Different ways to refresh or reload page using jQuery

2011-11-28T23:01:00.001-08:00

In this post, I will show you the different ways using which you can reload or refresh the webpage using jQuery. The first method is nothing to do with jQuery. It is a HTML tag which you need to put in the head section of your page and your page will get refreshed automatically after specified interval.


<meta http-equiv="refresh" content="10">

The meta tag with "http-equiv" is used to refresh the page. This attribute tells the browser that this meta tag is sending an HTTP command rather than a standard meta tag.

Refresh is an actual HTTP header used by the web server.The content attribute in the tag is having value in seconds. As per the above code, it is set to 10, which means after 10 seconds your page will get refreshed or reloaded.

You can also use jQuery to refresh/reload the page automatically. See below jQuery code.


function ReloadPage() { 
   location.reload();
};
 
$(document).ready(function() {
  setTimeout("ReloadPage()", 10000); .
});

location.reload() will reload the page again. The advantage of location.reload() is that it works with all the major browsers.

If you want to reload the page on click of button, then you can call location.reload() on button click event. See below jQuery code.


$(document).ready(function() {
     $('#btnReload').click(function() {
             location.reload();
       });
});

Creating Your Own jQuery Custom Selector

2011-11-28T22:46:00.000-08:00

jQuery supports a large subset of selectors defined by the CSS3 Selectors draft standard. Additionally it also contains some very useful pseudo classes (similar to :first-child, :hover etc).

Due to its extensible framework, the best part is that jQuery lets you create and define your own custom selectors with ease. A full list of jQuery selectors is available on the jQuery site.

In this article, we will learn how to create our own custom selector that identifies all the mailto: links on a page. Let us see some code first:

As you can observe, we have extended jQuery’s selector expressions under the jQuery.expr[':'] object. To learn more about this, visit the jQuery hot Selector engine called sizzle. We have defined a custom selector called :mailToLink to which we are passing an object, which is a collection of links. This selector looks for all anchor elements that contains an href attribute matching mailto.

That’s it. Our selector :mailToLink is ready and here’s how we can use it:

To test this selector, we have used some hyperlinks, out of which one of them is a mailto: link. When you click the button, we use our custom selector to indentify the :mailto link and set it’s color to red.

As you can see, we have extended jQuery’s expression engine with ease!

Web Browser Developer Tools vs Layout Engines

2011-11-28T22:23:00.001-08:00

A layout engine a.k.a web browser engine or browser rendering engine is a component that parses HTML, XML, CSS, Images etc. and renders it on the screen.

A browser developer tool lets you inspect, debug, analyze and diagnose issues with CSS, HTML, Scripts etc. inside your browser.

As a web developer, you must know what layout engines and developer tools your browser uses.

It helps to understand browser rendering and resolve issues when you are developing cross browser apps. Here’s a list of some popular browser developer tools and the layout engines for your reference.

Browseer Name	Layout Engine	Developer Tools
Chrome	WebKit	Google Chrome Inspector
FireFox	Gecko	Firebug
Internet Explorer and WP 7	Trident	IE Developer Tools
Konqueror	KHTML	KIO
Opera (desktop and mobile)	Presto	Opera DragonFly
Safari (desktop and mobile)	WebKit	Web Inspector

Hope this information will help you updated!!!!

Best way of using jQuery Selector

2011-11-28T22:12:00.001-08:00

It is pretty important to understand how to write efficient element selection statement. One has to be very careful while jQuery selector statement. Below are some tips on how to use your jQuery selectors efficiently.

1. Always try to use ID as selector

You can use ID as selector in jQuery. See below jQuery code.

$("#elmID");

When IDs are used as selector then jQuery internally makes a call to getElementById() method of Java script which directly maps to the element. When Classes are used as selector then jQuery has to do DOM traversal.So when DOM traversal is performed via jQuery takes more time to select elements. In terms of speed and performance, it is best practice to use IDs as selector.

2. Use class selector with tags

You can use CSS classes as selector. For example, to select elements with "myCSSClass" following jQuery code can be used.

$(".myCSSClass");

As said earlier, when classes are used DOM traversal happens. But there could be a situation where you need to use classes as selector. For better performance, you can use tag name with the class name. See below

$("div.myCSSClass");

Above jQuery code, restricts the search element specific to DIV elements only.

3. Keep your selector simple, don't make it complex

Avoid complex selectors. You should use make your selectors simple, unless required.

$("body .main p#myID em");

Instead of using such a complex selector, we can simplify it. See below.

$("p#myID em");

4.Don't use your selector repeatedly.

See below jQuery code. The selectors are used thrice for 3 different operation.

$("#myID").css("color", "red");$("#myID").css("font", "Arial");$("#myID").text("Error occurred!");

The problem with above code is, jQuery has to traverse 3 times as there are 3 different statements.But this can be combined into a single statement.

$("p").css({ "color": "red", "font": "Arial"}).text("Error occurred!");

5.Know how your selectors are executed

Do you know how the selectors are executed? Your last selectors is always executed first. For example, in below jQuery code, jQuery will first find all the elements with class ".myCssClass" and after that it will reject all the other elements which are not in "p#elmID".

$("p#elmID .myCssClass");

Hope this will help you. Happy coding!!!!

VisualStudio "Find in files" not working

2011-10-15T03:52:00.000-07:00

The "Find in files" function of Visual Studio (2008 or 2010) stops working. Whatever I search for it always says "No files were found to look in. Find was stopped in progress". It is very annoying. Since I have only found solution in blog.

The solution is to press Control + Scroll Lock and all is fixed. It works smart! :)

At present, the workaround is to press

Ctrl + Scroll Lock
Ctrl + Break
The Break key alone
ALT + Break
ALT + Scroll Lock

Thanks.

VS Macro / Shortcuts to Expand / Collapse all regions

2011-10-14T07:01:00.000-07:00

CTRL+M CTRL+M (that's two key presses!) - Collapse / Open the current parent region

CTRL+M CTRL+L - Collapse / Open all regions in document recursively (meaning you might get only one line in the document - one big namespace region which is collapsed or you'll see the entire page code uncollapsed)

CTRL+M CTRL+O - Collapse all regions not recursively.

What a "GO" statement do in T-SQL ?

2011-09-13T23:43:00.000-07:00

What a "GO" statement do in T-SQL ?

By definition it is a batch separator. It will run a batch and commit it. But along with that it also accepts one parameter which tells the SQL engine basically how many times to do the job.

For Example:

SELECT * FROM   sys.objects;
GO 3

It will show the output THREE times :)

Note: "GO" is the keyword used by SSMS to separate query batches. It can be configured in this location:

Tools » Options » Query Execution » SQL Server » General. Change the value for "Batch Separator:" in the right pane.

To see the immediate effect of this change, you need to close all query windows in the current session and open new query window.

Next Example:


IF EXISTS (SELECT 1
           FROM   tempdb.sys.objects
           WHERE  name LIKE '%#ProductTable%')
DROP TABLE #ProductTable;
 
CREATE TABLE #ProductTable
(
    ID INT IDENTITY (1, 1),
    Name VARCHAR (50)
);  
GO

INSERT  INTO #ProductTable (Name) VALUES  ('Office XP'); 
GO 3
 
SELECT * FROM #ProductTable;

OUTPUT:

Hope this helps you and thanks to SQLLion.

Introduction to Script#

2011-09-13T23:01:00.000-07:00

Have you heard about Script#?

I knew that there is a Java-to-Javascript converter called GWT (Google Web Toolkit) in Java World since long time back and I thought that it might be good if we, the C# developers, also have that kinda tools for ASP.NET web development.

Now C# developers can do the same using Nikhil Kothari's Script# project. This is not quite the same as using Atlas with ASP.NET though both cover similar territory.

Nikhil has written a C# compiler that outputs JavaScript instead of IL code. JavaScript is a powerful but not very friendly scripting language and Ajax is a technology that updates part of web pages from a web server without redrawing the entire page.

Script# is a compiler that generate the Javascript instead of MSIL from C# sourcecode. Like GWT (Google Web Toolkit) that can convert the Java code to browser-compliant JavaScript and HTML, Script# is able to convert the C# codes to Javascript (either human-readable format or compact one). It is the best tool for those who hate to write the Javascript in HTML view.

How it works?

Script# works by compiling C# source code and files directly into a single JavaScript file, in much the same way as the C# compiler that generates MSIL into a single assembly.

The inputs into the C# compiler are your source files, and any referenced assemblies. The referenced assemblies represent either script APIs in existing script files written manually, or script APIs defined within another Script# project with a corresponding generated script file.

The regular C# compiler is used to produce an assembly for your code and the XML doc-comments file that can then be used to produce documentation. The Script# compiler on the other hand generates a .js script file. All the script files - existing and generated – can then be deployed into a Web site or Web application running on any platform for use at runtime without any Script# dependency.

During compilation, the C# compiler and Script# compiler together provide build-time type checking and validation of your code. This helps catch typos and other common script errors at build-time on the development machine as opposed to at runtime on the end-user's machine.

The Script# compiler produces both release and debug versions of your script. The release version is minimized by removing whitespace and by reducing identifier lengths for internal and private members with shorter names. The debug version is formatted for readability and debuggability

The Script# System

Logically speaking there are three layers to the Script# system:

The Compiler

The Core RunTime

The Framework

Script# Compiler - The compiler compiles C# code into JavaScript, and is only needed on the development or build machine. The compiler assumes the existence of APIs defined in the Script# core runtime to represent classes and other OOP constructs defined in the originating C# source code.

Script# Runtime - At development time, the runtime provides the equivalent of mscorlib.dll. It defines various key .NET types such as System.Object, primitive types and other core BCL types needed to author and compile C# source code.

At runtime, the core runtime is a small bootstrapper script file that implements how various OOP constructs are defined and simulated in JavaScript, as well as providing basic extensions to existing JavaScript objects to implement functionality expected by .NET developers.

The default Script# runtime is implemented in sscorlib.dll and its accompanying runtime counterpart sscorlib.js. To use Microsoft ASP.NET Ajax, the equivalent pair consists of aacorlib.dll and MicrosoftAjax.js as its runtime counterpart.

Runtime assemblies shipping with Script# representing other script APIs such as Virtual Earth, RSS Feeds etc. ship in assemblies named ss*.dll.

Script# Framework - The framework is completely optional. The choice of framework also depends on the application and the developer. The compiler itself is not bound or dependent in any way against any particular framework choice. The default ScriptFX framework accompanying Script# ships in assemblies and scripts named ssfx.*.dll and ssfx.*.js.

Using Script#

Script# can be used either via the command-line (ssc.exe) or via MSBuild (via a custom task added to your .csproj profile file). The MSBuild approach is recommended.

Maintain Scroll Position After Postback in Asp.Net

2011-08-29T01:07:00.000-07:00

In this example i'm explaining different methods of maintaining scroll position after postback in asp.net 2.0, 3.5 & 4.0 web pages or applications.

Method : 1

Write below mention directive in page directive section of html source of aspx page to maintain scroll position of only one page or selected pages rather then whole web application.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" 

        MaintainScrollPositionOnPostback="true"  Inherits="_Default" %>

Method : 2

To maintain scroll position programmatically use code mentione below.

System.Web.UI.Page.MaintainScrollPositionOnPostBack = true;

Method : 3

To maintain scroll position application wide or for all pages of web application we can write below mentioned code in pages section of web.config file so that we don't need to add page directive in each and every page.

<pages maintainScrollPositionOnPostBack="true">

Hope this helps.

Design Patterns : An introduction

2011-01-12T02:49:00.000-08:00

Design Patterns

Design Patterns are an essential tool for any object orientated programmer who wants to take his/her skills to the next level. Understanding the specifics of Design Pattern practices and methodologies will help developers uncover reoccurring patterns in software development and give them the tools to apply the correct solution.

Types of Design Patterns

Informal Design Patterns - such as the use of standard code constructs, best practice, well structured code, common sense, the accepted approach, and evolution over time.
Formal Design Patterns - documented with sections such as "Context", "Problem", "Solution", and a UML diagram.

Formal patterns usually have specific aims and solve specific issues, whereas informal patterns tend to provide guidance that is more general. Formal patterns usually have specific aims and solve specific issues, whereas informal patterns tend to provide guidance that is more general.

For example, some patterns provide presentation logic for displaying specific views that make up the user interface. Others control the way that the application behaves as the user interacts with it. There are also groups of patterns that specify techniques for persisting data, define best practices for data access, and indicate optimum approaches for creating instances of objects that the application uses.

The following list shows some of the most common design patterns within these groups:

Presentation Logic
1. Model-View-Controller (MVC)
2. Model-View-Presenter (MVP)
3. Use Case Controller

Host or Behavioral
1. Command
2. Publish-Subscribe / Observer
3. Plug-in / Module / Intercepting Filter

Structural
1. Service Agent / Proxy / Broker
2. Provider / Adapter

Common Table Expressions (CTEs)

2011-01-11T23:22:00.000-08:00

Common Table Expressions (CTEs)

Why we need CTEs ?

You need to implement recursive queries to retrieve data which is presented in a hierarchical format. We normally resort to implementing views, cursors or derived tables and perform queries against them. The problem arises when the hierarchy level increases as SQL Server is limited to 32 levels of recursion.

We need a better way to implement recursive queries in SQL Server 2005 / 08. How do we do it? Use CTE.

Common Table Expressions (CTEs) are one of the most exciting features to be introduced with SQL Server 2005. CTEs come in 2 forms, non-recursive and recursive

A CTE is a "temporary result set" that exists only within the scope of a single SQL statement. It allows access to functionality within that single SQL statement that was previously only available through use of functions, temp tables, cursors, and so on.

CTE can be used for both selects and DML statements. CTEs can also contain references to themselves. CTEs can also be used in place of views.

You can also use a query hint to stop a statement after a defined number of loops. This can stop a CTE from going into an infinite loop on a poorly coded statement. You do this by including the MAXRECURSION keyword in the SELECT query referring to the CTE.

1. Non-Recursive CTE

Non-Recursive CTE as a derived table, or a temporary view.

The concept behind a CTE is simplicity itself. Consider the following statement:

with MyCTE(x)
as
(select x = 'Kannan')

select x from MyCTE

In brackets after the 'as' keyword is the query that defines the CTE and it simply returning the string "Kannan".

2. Recursive CTE

To print the numbers 5 to 10 using SQL. How ? Before we go to actual code, let we see the syntex of it.

Syntex

WITH cte_alias (column_aliases) 
AS 
(
cte_query_definition   --initialization
UNION ALL
cte_query_definition2 --recursive execution
) 
SELECT * FROM cte_alias

The table defined in the CTE can be referenced in the CTE itself to give a recursive expression, using union all.

DECLARE @Start INT
DECLARE @End INT
SET @Start = 5;
SET @End = 10;

WITH CTE AS
(SELECT @Start AS NUM
UNION ALL 
SELECT NUM + 1 FROM CTE WHERE NUM < @End
)

SELECT * FROM CTE

The query:

SELECT @Start AS NUM

is called the anchor member. This is executed in the first pass and will populate the CTE with the result, in this case 5. This initial CTE is repeatedly executed until the complete result set is returned. The next entry:

SELECT NUM + 1 FROM CTE WHERE NUM < @End

is a recursive member as it references the CTE, CTE. The recursive member is executed with the anchor member output to give 6. The next pass takes 6 as input and returns 7, and so on so that we arrive at a CTE populated with rows as follows:

The recursion will terminate when the recursive member produces no rows – in this case recursion stops when the length of x equals 10.

Note:

Note the ";" before the CTE definition – that's just a syntax requirement if the CTE declaration is not the first statement in a batch.

Disadvantage :

1. CTE will be available with the scope of the statement or block of code.
2. Compute, Order By (without a TOP), INTO, Option, FOR XML, and FOR BROWSE are all not allowed.

Hope this will help you. If so please add your comments. Thanks.

Just in Time (JIT) and its types

2010-11-18T03:24:00.000-08:00

Just in Time (JIT)

JIT is responsible for converting the managed code into machine code. It is a part of the runtime execution environment.

JIT known as dynamic translation is a technique for improving the runtime performance of a computer program.

JIT builds upon two earlier ideas in run-time environments:

Byte code compilation
Dynamic compilation.

It converts code at runtime prior to executing it natively, for example byte code into native machine code.

The performance improvement over interpreters originates from caching the results of translating blocks of code, and not simply reevaluating each line or operand each time it is met.

It also has advantages over statically compiling the code at development time, as it can recompile the code if this is found to be advantageous, and may be able to enforce security guarantees.

Thus JIT can combine some of the advantages of interpretation and static compilation.

Several modern runtime environments, such as Microsoft's .NET Framework and most implementations of Java and most recently Action script 3, rely on JIT compilation for high-speed code execution

JIT are of three types :

Pre JIT
Econo JIT
Normal JIT

1. Pre JIT : Compiles entire code into native code at one stretch

It converts all the code in executable code
it is slow
It compiles complete source code into native code in a single compilation cycle.
This is done at the time of deployment of the application.

2. Econo JIT : Compiles code part by part freeing when required

It will convert the called executable code only.
it will convert code every time when a code is called again.
It compiles only those methods that are called at runtime.
these compiled methods are removed when they are not required.
This compiler converts the MSIL code into native code without any optimizations

3. Normal JIT Compiles only that part of code when called and places in cache

It will only convert the called code
It will store in cache so that it will not require converting code again.
Normal JIT is fast.
Compiles only those methods that are called at runtime.
These methods are compiled the first time they are called, and then they are stored in cache.
When the same methods are called again, the compiled code from cache is used for execution.

WCF Binding Comparison

2010-10-29T05:18:00.000-07:00

WCF Binding Comparison

In my ongoing quest to produce the simplest table possible summarizing the key differences between the various Windows Communication Foundation (WCF) built-in bindings, I came up with the following:

Binding Class Name	Transport	Message Encoding	Message Version	Security Mode
BasicHttpBinding	HTTP	Text	SOAP 1.1	None
WSHttpBinding	HTTP	Text	SOAP 1.2 & WS-A 1.0	Message
WSDualHttpBinding	HTTP	Text	SOAP 1.2 & WS-A 1.0	Message
WSFederationHttpBinding	HTTP	Text	SOAP 1.2 & WS-A 1.0	Message
NetTcpBinding	TCP	Binary	SOAP 1.2	Transport
NetPeerTcpBinding	P2P	Binary	SOAP 1.2	Transport
NetNamedPipesBinding	Named Pipes	Binary	SOAP 1.2	Transport
NetMsmqBinding	MSMQ	Binary	SOAP 1.2	Message
MsmqIntegrationBinding	MSMQ	X**	Not Supported	Transport

Types of Services in WCF

2010-10-29T03:58:00.000-07:00

There are three types of services in WCF, and they are the following:

Typed
Untyped
Typed message

Typed Service

A typed service is the simplest of services, and is very similar to the methods in a class, in that both the parameters and method return values can be both simple or complex data types.

A typed service can also return a value or return a modified parameter value. The following example illustrates a typed service in which typed operations are used:

[ServiceContract(SessionMode = SessionMode.Required)]
public interface IBookOrder
{

[OperationContract]
void PlaceOrder(string title, decimal cost);

}

This next example shows the use of the ref parameter to return a modified parameter value:

[ServiceContract(SessionMode = SessionMode.Required)]
public interface IBookOrder
{

[OperationContract]
void PlaceOrder(string title, decimal cost, ref ordernumber);

}

Data contracts provide the ability to extend this functionality and accept complex data types as parameters or returned results.

Typed Message Service

A typed message service accepts and returns message information via custom classes that are defined by message contracts. With a typed message service the operation accepts a custom message parameter in the form of a message class, and the responsibility of deciphering the message falls upon the service operation.

The following example shows a service contract along with a defined typed message that is used as a parameter in a typed service operation:

[ServiceContract]
public interface IBookOrder
{

[OperationContract]
void PlaceOrder(Contract MyContract);

}

[MessageContract]
public class MyContract
{

[MessageHeader]
string Title;

[MessageBodyMember]
decimal cost;

}

Untyped Service

Untyped services let you do your work at message level, so this is the most complex of the service types. At this level the service operation accepts and returns message objects so it is recommended that you use this type of service only when you need this level of control, that is, working directly with the message.

The following example shows an operation contract passing a message object as an untyped service operation:

[ServiceContract(SessionMode = SessionMode.Required)]
public interface IBookOrder
{

[OperationContract]
void PlaceOrder(message IncomingMessage);

}

WCF Service Bindings - Basic

2010-10-29T00:06:00.000-07:00

Windows Communication Foundation Bindings

This article offers a brief explanation on the basic concepts of the Communication part in the Windows Communication Foundation - WCF. In order to communicate with a WCF service, the client needs to know simple details like 'ABC' of the service.

Whats meant by ABC of WCF ?
Before we learn the ABC of WCF, we need to know how a WCF service is made accessible to the clients.

A WCF service allows communication through an Endpoint. And the endpoint is the only point of communication of the WCF service that enables message exchange with the client as shown in below figure.

And this Endpoint needs to set the ABC attributes of the WCF service as shown in the below figure.

Thus in the WCF world, ABC is an abbreviation of Address, Binding and Contract attributes of an Endpoint.

An example of the Endpoint

Let us quickly run through an example of an endpoint setting in the web.config file at the service side.

<endpoint 
address="http://localhost:8731/EmpWCFService.ServiceImpl.Manager/"
binding="basicHttpBinding"
contract="EmpWCFService.ServiceContract.IEmployee" />

Where,
- address is the network address of the service,
- binding specifies transport protocol (HTTP, TCP, etc.) selected for the service &
- contract is the interface the service implements.

So, what is the Binding?

The Binding is an attribute of an endpoint and it lets you configure transport protocol, encoding and security requirements as shown in the below figure.

Types of Binding

WCF supports nine types of bindings. WCF allows you to transmit messages using different transport protocols (such as HTTP, TCP, and MSMQ) and using different XML representations (such as text, binary, or MTOM).

Basic binding - BasicHttpBinding
- It is suitable for communicating with ASP.NET Web services (ASMX)-based services that comfort with WS-Basic Profile conformant Web services.
- This binding uses HTTP as the transport and text/XML as the default message encoding.
- Security is disabled by default
- This binding does not support WS-* functionalities like WS- Addressing, WS-Security, WS-ReliableMessaging
- It is fairly weak on interoperability.
Web Service (WS) binding - WSHttpBinding
- Defines a secure, reliable, interoperable binding suitable for non-duplex service contracts.
- It offers lot more functionality in the area of interoperability.
- It supports WS-* functionality and distributed transactions with reliable and secure sessions using SOAP security.
- It uses HTTP and HTTPS transport for communication.
- Reliable sessions are disabled by default.
TCP binding - NetTcpBinding
- This binding provides secure and reliable binding environment for .Net to .Net cross machine communication.
- By default it creates communication stack using WS-ReliableMessaging protocol for reliability, TCP for message delivery and windows security for message and authentication at run time.
- It uses TCP protocol and provides support for security, transaction and reliability.
MSMQ binding - NetMsmqBinding
- This binding provides secure and reliable queued communication for cross-machine environment.
- Queuing is provided by using MSMQ as transport.
- It enables for disconnected operations, failure isolation and load leveling
Peer network binding - NetPeerTcpBinding
- This binding provides secure binding for peer-to-peer environment and network applications.
- It uses TCP protocol for communication
- It provides full support for SOAP security, transaction and reliability.
Duplex WS binding - WSDualHttpBinding
- This binding is same as that of WSHttpBinding, except it supports duplex service.
- Duplex service is a service which uses duplex message pattern, which allows service to communicate with client via callback.
- In WSDualHttpBinding reliable sessions are enabled by default. It also supports communication via SOAP intermediaries.
IPC binding
- Offered by the NetNamedPipeBinding class, this uses named pipes as a transport for same-machine communication. It is the most secure binding since it cannot accept calls from outside the machine and it supports a variety of features similar to the TCP binding.
Federated WS binding
- Offered by the WSFederationHttpBinding class, this is a specialization of the WS binding, offering support for federated security.
MSMQ integration binding
- Offered by the MsmqIntegrationBinding class, this converts WCF messages to and from MSMQ messages, and is designed to interoperate with legacy MSMQ clients.

That's all at this moment. Will see more in the next post.

    static void Main(string[] args)
    {
        string s = "toUpperFirstLetter";

        // ToUpperFirstLetter is the extension method defined below             
        Console.WriteLine(s.ToUpperFirstLetter());
        
        // output:  ToUpperFirstLetter             
        Console.ReadLine();
    }
}

// string extension class     
public static class StringExtension
{
    // string extension method ToUpperFirstLetter         
    public static string ToUpperFirstLetter(this string source)
    {
        if (string.IsNullOrEmpty(source))
            return string.Empty;
        // convert to char array of the string             
        char[] letters = source.ToCharArray();
        
        // upper case the first char             
        letters[0] = char.ToUpper(letters[0]);
        
        // return the array made of the new char array             
        return new string(letters);
    }
}

Difference between WCF and Web service

2010-07-28T07:42:00.000-07:00

Difference between WCF and Web service

Web service is a part of WCF. WCF offers much more flexibility and portability to develop a service when comparing to web service. Still we are having more advantages over Web service, following table provides detailed difference between them.

Features	Web Service	WCF
Hosting	It can be hosted in IIS	It can be hosted in IIS, windows activation service, Self-hosting, Windows service
Programming	[WebService] attribute has to be added to the class	[ServiceContraact] attribute has to be added to the class
Model	[WebMethod] attribute represents the method exposed to client	[OperationContract] attribute represents the method exposed to client
Operation	One-way, Request- Response are the different operations supported in web service	One-Way, Request-Response, Duplex are different type of operations supported in WCF
XML	System.Xml.serialization name space is used for serialization	System.Runtime.Serialization namespace is used for serialization
Encoding	XML 1.0, MTOM(Message Transmission Optimization Mechanism), DIME, Custom	XML 1.0, MTOM, Binary, Custom
Transports	Can be accessed through HTTP, TCP, Custom	Can be accessed through HTTP, TCP, Named pipes, MSMQ,P2P, Custom
Protocols	Security	Security, Reliable messaging, Transactions

Difference between BasicHttpBinding and WsHttpBinding

2010-07-28T06:42:00.000-07:00

Difference between BasicHttpBinding and WsHttpBinding

If we want to summarize in one sentence, the difference between WsHttpBinding and BasicHttpBinding is that WsHttpBinding supports WS-* specification. WS-* specifications are nothing but standards to extend web service capabilities.

Below is a detailed comparison table between both the entities from security, compatibility, reliability and SOAP version perspective.

Criteria	BasicHttpBinding	WsHttpBinding
Security support	This supports the old ASMX style, i.e. WS-BasicProfile 1.1.	This exposes web services using WS-* specifications.
Compatibility	This is aimed for clients who do not have .NET 3.0 installed and it supports wider ranges of clients. Many of the clients like Windows 2000 still do not run .NET 3.0. So older version of .NET can consume this service.	As its built using WS-* specifications, it does not support wider ranges of client and it cannot be consumed by older .NET version less than 3 version.
Soap version	SOAP 1.1	SOAP 1.2 and WS-Addressing specification.
Reliable messaging	Not supported. In other words, if a client fires two or three calls you really do not know if they will return back in the same order.	Supported as it supports WS-* specifications.
Default security options	By default, there is no security provided for messages when the client calls happen. In other words, data is sent as plain text.	As `WsHttBinding` supports WS-*, it has WS-Security enabled by default. So the data is not sent in plain text.
Security options	None Windows – default authentication Basic Certificate	None Transport Message Transport with message credentials

One of the biggest differences you must have noticed is the security aspect. By default, BasicHttpBinding sends data in plain text while WsHttpBinding sends it in encrypted and secured manner.

To demonstrate the same, lets make two services, one using BasicHttpBinding and the other using WsHttpBinding and then lets see the security aspect in a more detailed manner.

WCF Data Services vs WCF RIA Services

2010-07-28T05:01:00.000-07:00

To sum up my findings as to the differences between WCF Data Services vs WCF RIA Services.

WCF (ADO.NET) Data Services	WCF (.NET) RIA Services
Expose data model as RESTful web service	Prescriptive approach to n-tier app development
Cross platform interoperation as a goal - “Unlock data silos” - Out-of-box support from future MS products such as SQL2008 R2, Azure, Excel 2010, SharePoint 2010	Designed specifically for end-to-end Silverlight & ASP.NET solutions - Some technology proprietary to Silverlight (no WPF support) - Use ASP.NET Authentication/Roles across SL and ASP.NET - ASP.NET/AJAX can also access service layer
Loosely coupled clients and servers	Client & server are designed and deployed together
Service layer exposes “raw” data sources	Opportunity to easily add business logic into service layer - Encourage “domain” concepts - Strong validation framework - Offline / Sync enabled
Service can be consumed from .NET, Silverlight, AJAX, PHP and Java (libraries available)	Service can be consumed easily from SL, AJAX, WebForms
Service’s data source must: - Expose at least one IQueryable property - Implement IUpdateable if you desire updates	Service exposes domain objects via convention: - IQueryable GetX - UpdateX/InsertX/DeleteX
No design time experience yet (??)	Design time experience with data sources, drag drop etc
- OData for all clients - Within OData, multiple formats supported (JSON, XML etc)	- SOAP (binary) for SL clients - JSON for AJAX clients - SOAP (XML) for other clients
Discoverable (?)	Non-discoverable
Hosted as WCF Service (.svc)	Old version hosted in custom web handler (.axd). New version is WCF service.
Standardized on OData protocol	Will “support” OData
More mature – public for at least 2 years, formerly “Project Astoria”	Less mature – public for 6 months

Common features

Based on WCF
Use a RESTful architecture
Can be used to expose any data source (sql, xml, poco/objects etc.)
Client side libraries provide ability to query using LINQ

General

Currently they do not share much (any?) technology / code
RIA Services is not based on top of Data Services
RIA Services & Data Services will “align”
OData eventually pushed down into WCF stack

"Publish failed" in Visual Studio 2008

2010-07-15T08:21:00.000-07:00

I was publishing a website today, and received an error message in the status bar indicating 'Publish failed. This was the only info I got, and couldn’t figure out what had happened as I had published successfully just minutes prior.

It turns out that there was an image that got included in my .csproj project file that had been deleted, and there was an error trying to locate it.

If you look in the output window (ctrl + alt + o) you will get a detailed list of any errors that occurred in the publishing process. I simply had to remove the image from the project file (as it didn’t exist any more anyway) and everything worked.

ASP.NET 3.5 vs ASP.NET 4.0

2010-07-01T03:10:00.000-07:00

Main Differences between ASP.NET 3.5 and ASP.NET 4.0.

ASP.NET 3.5 is having the following main features which are not availablle in the prior releases

AJAX integration
LINQ
Automatic Properties
Lambda expressions

I hope it would be useful for everyone to know about the differences about asp.net 3.5 and its next version asp.net 4.0 Because of space consumption I'll list only some of them here.

1. Client Data access:

ASP.NET 3.5: There is no direct method to access data from client side. We can go for any of these methods

Pagemethods of script manager
ICallbackEventHandler interface
XMLHttphanlder component

ASP.NET 4.0: In this framework there is an inbuilt feature for this. Following are the methods to implement them.

Client data controls
Client templates
Client data context

i.e we can access the data through client data view & data context objects from client side.

2) Setting Meta keyword and Meta description:

Meta keywords and description are really useful for getting listed in search engine.

ASP.NET 3.5: It has a feature to add meta as following tag

<meta name="keywords" content="These, are, my, keywords" /%>
  <meta name="description" content="This is the description of my page" /%>

ASP.NET 4.0: Here we can add the keywords and description in Page directives itself as shown below.

< %@ Page Language="C#"  CodeFile="Default.aspx.cs" 
  Inherits="_Default" 
  Keywords="Keyword1,Key2,Key3,etc" 
  Description="description" %>

3) Enableviewstage property for each control

ASP.NET 3.5: this property has two values "True" or "false"

ASP.NET 4.0: ViewStateMode property takes an enumeration that has three values: Enabled, Disabled, and Inherit. Here inherit is the default value for child controls of a control.

4) Setting Client IDs

Some times ClientID property creates head ach for the programmers.

ASP.NET 3.5: We have to use ClientID property to find out the id which is dynamically generated

ASP.NET 4.0: The new ClientIDMode property is introduced to minimize the issues of earlier versions of ASP.NET.

It has following values.

AutoID - Same as ASP.NET 3.5
Static - There won't be any separate clientid generated at run time
Predictable-These are used particularly in datacontrols. Format is like clientIDrowsuffix with the clientid vlaue
Inherit- This value specifies that a control's ID generation is the same as its parent.

List all stored procedure created / modified in N days

2010-06-28T09:52:00.000-07:00

Following script will provide name of all the stored procedure which were CREATED in last 7 days, they may or may not be modified after that.


SELECT name
FROM sys.objects
WHERE type = 'P'
AND DATEDIFF(D,create_date, GETDATE()) < 7
----Change 7 to any other day value.

Following script will provide name of all the stored procedure which were MODIFIED in last 7 days, they may or may not be modified after that.


SELECT name
FROM sys.objects
WHERE type = 'P'
AND DATEDIFF(D,modify_date, GETDATE()) < 7
----Change 7 to any other day value

'HttpUtility' is not a member of 'Web' in console application VS2010.

2010-06-18T03:03:00.000-07:00

Today I started my first console application developmentin VS 2010.

After I added the below code

System.Web.HttpUtility.UrlEncode(item)

and build the application, the system throws the error message like

Error message: 'HttpUtility' is not a member of 'Web'.

This error message suggests to add a reference to System.Web. When I look into it over the reference list, its was not there. I only have "System.Web.ApplicationServices" and "System.Web.Services". I dont know why its not there in the list?

Then my friend said, 'target framework may be different'. After that I checked the target framework, its was .NET Framework 4 Client Profile. Then I changed it as .NET Framework 4. Now my code works fine.

Hope this ll help you.

jQuery UI Date Picker control issue with .Net

2010-06-10T07:51:00.000-07:00

I build .net applications that require date entry, so I implement the Date Picker control often. Unfortunately, there is a problem when it is used on a field that is validated using a .Net validation control.

Upon clicking on a date, I get the following error:

length is null or not an object

This only occurs when using Internet Explorer. Currently, my only solution is to edit the source code.

Locate the following code in jquery-ui.js or ui.datepicker.js:

inst.input.trigger('change')

Replace it with:

if (!$.browser.msie){inst.input.trigger('change')}

This prevents the change event firing in IE.

New <%: %> Code Syntax in ASP.NET 4.0

2010-04-07T22:56:00.000-07:00

HTML Encoding

Cross-site script injection (XSS) and HTML encoding attacks are two of the most common security issues that plague web-sites and applications. They occur when hackers find a way to inject client-side script or HTML markup into web-pages that are then viewed by other visitors to a site.

This can be used to both vandalize a site, as well as enable hackers to run client-script code that steals cookie data and/or exploits a user’s identity on a site to do bad things.

One way to help mitigate against cross-site scripting attacks is to make sure that rendered output is HTML encoded within a page. This helps ensures that any content that might have been input/modified by an end-user cannot be output back onto a page containing tags like <script> or <img> elements.

How to HTML Encode Content Today

ASP.NET applications (especially those using ASP.NET MVC) often rely on using code-nugget expressions to render output. Developers today often use the Server.HtmlEncode() or HttpUtility.Encode() helper methods within these expressions to HTML encode the output before it is rendered. This can be done using code like below:

<div class="someclass">
<%= Server.HtmlEncode(Model.Content) %>
</div>

While this works fine, there are two downsides of it:

It is a little verbose
Developers often forget to call the Server.HtmlEncode method – and there is no easy way to verify its usage across an app

New Code Nugget Syntax

With ASP.NET 4 we are introducing a new code expression syntax () that renders output like blocks do – but which also automatically HTML encodes it before doing so.

This eliminates the need to explicitly HTML encode content like we did in the example above. Instead, you can just write the more concise code below to accomplish the exact same thing:

<div class="someclass">
<%: Model.Content %>
</div>

We chose the syntax so that it would be easy to quickly replace existing instances of code blocks. It also enables you to easily search your code-base for elements to find and verify any cases where you are not using HTML encoding within your application to ensure that you have the correct behavior.

Happy Coding!!!

NUnit Test vs MsTest

2010-03-08T01:06:00.001-08:00

What are the differences between the two most popular UNIT testing frameworks in the .NET world: the open source NUnit and the commercial MsTest.

Here’s a short list of what i remember instantly:

Nunit contains a [TestCase] attribute that allows implementing parametrized tests. this does not exist in msTest
MsTest's ExpectedException attribute has a bug where the expected message is never really asserted even if it's wrong - the test will pass.
Nunit has an Assert.Throws API to allow testing an exception on a specific line of code instead of the whole method (you can easily implement this one yourself though)
Nunit contains a fluent version of Assert api (as already mentioned - Assert.That..)
Nunit is much faster
NUnit can run tests in 32 and 64 bit (MSTest only runs them in 32 bit IIRC)
NUnit allows abstract classes to be test fixtures (so you can inherit test fixtures). MsTest does not.
NUnit allows non public classes to be test fixtures (as of the latest version)
NUnit was created SOLELY for the idea of unit testing. MsTest was created for Testing - and also a bit of unit testing.
NUnit contains PNunit (running prallel tests with Nunit). MsTest only adds this ability in vs 2010

given all these – MsTest has much better abilities for integration based testing (all these are things Nunit doesn’t even want to have):

Ability to do data-driven tests from a db data source
Ability to do performance testing
Ability to determine the order of tests (ordered tests)
Ability to easily setup and teardown and generate database data
Great integration with team system reporting for LOADS of statistics

having said all these:

if you’re working with team system, I’d use MsTest. the integration with other team system tools and reporting is just beyond compare and the reporting alone helps alot to find recurring breaking tests, code churn vs. new tests and others.

Happy coding!

.NET 4 String Function to Check for Empty Strings

2010-02-11T03:06:00.000-08:00

Question is...

How to Check an Empty Strings or not in ASP.NET 4.0?

How many times have you written code similar to this?


string firstName = FirstName.Text.Trim();

if (!string.IsNullOrEmpty(firstName))
{
    // do something
}

// or

if (someParam == null || string.IsNullOrEmpty(someParam.Trim())
    throw new ArgumentException("Empty string", "someParam");

// do something

A nice little time-saver for those guard functions is now included in .NET 4 - the IsNullOrWhiteSpace function


if (!string.IsNullOrWhiteSpace(FirstName.Text))
{
    // do something
}

IsNullOrWhiteSpace checks for null, empty or whitespace characters.

Sure, it’s a little thing, but it’s nice to have it in there, especially considering we get all sorts of nice new little things, and the client framework install is still smaller than it was in .NET 3.5

Convert a DataTable to a List<> using C#

2010-02-10T01:24:00.000-08:00

Question is...

Convert a DataTable to a List<> using C#

To convert a DataTable to a List<> in .NET 2.0.

Here’s the code to do so:


// Assuming there is a DataTable called dt
List<DataRow> drlist = new List<DataRow>();

foreach (DataRow row in dt.Rows)
{
    drlist.Add((DataRow)row);
}

Please note that this is just a prototype and may not cover all scenarios.

Note: I have not tested this but in .NET 3.5, you should be able to do this:


List<DataRow> drlist = dt.AsEnumerable().ToList();

Simplest way to Programmatically ShutDown or Restart your System using C#

2010-02-10T00:16:00.000-08:00

Question is...

Simplest way to Programmatically ShutDown or Restart your System using C#

One of the ways to ShutDown or Restart your system is to use WMI (Windows Management Interface). However it does require you to write a few lines of code.

I have found that the simplest way to ShutDown or Restart your computer is to use the Process class in the System.Diagnostics namespace. Here’s an example:


private void btnShutDown_Click(object sender, EventArgs e)
{
    Process.Start("shutdown", "-s -f -t 0"); 
}

private void btnRestart_Click(object sender, EventArgs e)
{
    Process.Start("shutdown", "-r -f -t 0"); 
}

Convert a String Array to a Decimal Array using C#

2010-02-10T00:14:00.000-08:00

Question is...

Convert a String Array to a Decimal Array using C#

The Array.ConvertAll() method is a very useful method to convert an array of one type to an array of another type.

Here’s how to use ConvertAll() to convert a String[] to Decimal[]


static void Main(string[] args)
{
    string[] strArray = new string[] { "1164", "2213" };

    decimal d;
    decimal[] d1;

    // Check if string can be converted to decimal equivalent
    if (strArray.All(number => Decimal.TryParse(number, out d)))
    {
       d1 = Array.ConvertAll<string, decimal>(strArray, Convert.ToDecimal);
    }
}

The first step is to use Enumerable.All(TSource) to determine whether all the elements in a sequence satisfy a condition, in our case, if all the elements of the array can be converted to its decimal equivalent.

Once this can be done, we use ConvertAll() to convert an array of string to an array of decimal.

Convert LowerCase and UpperCase to TitleCase in C#

2010-02-10T00:08:00.000-08:00

Question is...

Convert LowerCase and UpperCase to TitleCase in C#

The String class has the ToLower() and the ToUpper() methods to convert a string to lowercase and uppercase respectively.

However when it comes to converting the string to TitleCase, the ToTitleCase() method of the TextInfo class comes very handy. Let me demonstrate this with an example:


class Program
{
static void Main(string[] args)
{
  string strLow = "lower case";
  string strT = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(strLow);
  Console.WriteLine("Lower Case to Title Case: " + strT);
   
  string strCap = "UPPER CASE";
  strT = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(strCap.ToLower());
  Console.WriteLine("Upper Case to Title Case: " + strT);
  Console.ReadLine();
}
}

Make sure you import the System.Globalization namespace. As you can observe, we are using the CurrentCulture.TextInfo property to retrieve an instance of the TextInfo class based on the current culture.

Note:
As mentioned on the site, "this method does not currently provide proper casing to convert a word that is entirely uppercase, such as an acronym". This is the reason why we first convert strCap to lower case and then supply the lowercase string to ToTitleCase() in the following manner:

CultureInfo.CurrentCulture.TextInfo.ToTitleCase(strCap.ToLower());

Convert Enum to List<> using C#

2010-02-10T00:06:00.000-08:00

Question is...

Convert Enum to List<> using C#

A user recently asked me how to convert an Enum to a List<>.

Here's the code to do so:


class Program
{
    enum Days { Sat, Sun, Mon, Tue, Wed, Thu, Fri };

    static void Main(string[] args)
    {
        Array arr = Enum.GetValues(typeof(Days));
        List<string> lstDays = new List<string>(arr.Length);

        for (int i = 0; i < arr.Length; i++)
        {
            lstDays.Add(arr.GetValue(i).ToString());
        }
    }
}

Find Out the Image Type without Checking its Extension using C#

2010-02-10T00:04:00.000-08:00

Question is...

Find Out the Image Type without Checking its Extension using C#

My colleague called up with a query. His application accepted images to be uploaded to a central server. Later the application processed the images and separated them according to the Image Type. They determined the image type by checking the extension of the image uploaded –- a very common practice of detecting the image type.

The issue here was that some images which were actually gif’s were renamed as jpeg's and then uploaded, which led to faulty image processing. The requirement was to determine the correct image type in the simplest possible way even if the extension was renamed.

Here’s what I suggested:


try
{
    Image imgUp = Image.FromFile(Server.MapPath("~/images/abc.jpg"));

    if (imgUp.RawFormat.Equals(ImageFormat.Jpeg))
        Response.Write("JPEG");

    else if (imgUp.RawFormat.Equals(ImageFormat.Gif))
        Response.Write("GIF");
}
catch (Exception ex)
{
}

How to calculate the CPU Usage Programmatically using C#

2010-02-09T23:59:00.000-08:00

Question is...

How to calculate the CPU Usage Programmatically using C#

The PerformanceCounter class represents a WindowsNT performance counter component. To read from a performance counter, we first create an instance of the PerformanceCounter class supplying the CategoryName, CounterName, and InstanceName as parameters to the constructor and then call the NextValue() method to take a performance counter reading.

Import the namespaces System.Diagnostics and System.Threading.


static PerformanceCounter cpuUsage;
public static void Main(string[] args)
{
    cpuUsage =
        new PerformanceCounter("Processor", "% Processor Time", "_Total");

    Console.WriteLine(cpuUsage.NextValue() + " %");
    Thread.Sleep(1000);

    Console.WriteLine(cpuUsage.NextValue() + " %");
    Console.Read();
}

Note:
Observe that we are calling NextValues() twice and after a delay of 1 second. This is because performance counters need two samples to perform the calculation and the counter value is updated once per second, hence the 1 second delay between the two calls.

Count Words and Characters in a String using C#

2010-02-09T23:56:00.000-08:00

Question is...

Count Words and Characters in a String using C#

A user recently asked me a question on how to use Regular Expressions to count words and characters in a string. Here’s how:

First add a reference to System.Text.RegularExpressions

Here the strOriginal is your string.


// Count words
MatchCollection wordColl =
    Regex.Matches(strOriginal, @"[\S]+");

Console.WriteLine(wordColl.Count.ToString());

// Count characters. White space is treated as a character
MatchCollection charColl = Regex.Matches(strOriginal, @".");
Console.WriteLine(charColl.Count.ToString());

Find Information about your Network Cards using C#

2010-02-09T23:52:00.000-08:00

Find Information about your Network Cards using C#

Here’s a small snippet of code of how to find out which network cards are enabled and able to transmit data on your machine. Here’s the code.

Add a reference to System.Net.NetworkInformation


var nics = NetworkInterface.GetAllNetworkInterfaces()
       .Where(o => o.OperationalStatus == OperationalStatus.Up);

foreach (var item in nics)
{
    Response.Write(item.Description + "<br />");
    Response.Write(item.Name + "<br />");
    Response.Write(item.Speed + "<br />");
    Response.Write(item.NetworkInterfaceType + "<br /><br />");
}

Hiding a File using C#

2010-02-09T23:50:00.000-08:00

Hiding a File using C#

The FileInfo class is very useful class that contains methods for the creation, copying, deletion, moving, and opening of files. Here’s how to hide a file using C#.


class Program
{
    static void Main(string[] args)
    {
        try
        {
            string filePath = @"D:\Network.txt";
            FileInfo f = new FileInfo(filePath);
            f.Attributes = FileAttributes.Hidden;
            Console.WriteLine("File Hidden");
        }
        catch (Exception ex)
        {
            // handle ex
        }
    }
}

Retrieve a List of the Services Running on your Computer using C#

2010-02-09T23:45:00.001-08:00

Retrieve a List of the Services Running on your Computer using C#

The ServiceController class can be used to retrieve a list of the services running on your computer. The GetServices() can be used to do so. Here’s an example to list the services that are running on your machine

Add a reference to System.ServiceProcess.

Then write the following code:


using System;
using System.ServiceProcess;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
         {
            try
            {
                ServiceController[] sController = 
                                          ServiceController.GetServices();
                foreach (ServiceController sc in sController)
                {
                    if (sc.Status.ToString() == "Running")
                    {
                        Console.WriteLine(sc.ServiceName);
                    }
                }
                Console.ReadLine();
            }
            catch (Exception ex)
            {
                // handle ex
            }
        }
    }
}

Optional parameters and named parameters in C# 4.0

2010-02-09T23:31:00.000-08:00

Optional parameters and named parameters in C# 4.0

Imagine you have two List. Two new features to C# 4.0 are optional parameters and named parameters.

Optional parameters have been a part of VB.Net but it's now possible to do this in C#. Instead of using overload methods, you can do this in C#:


private string SomeMethod(string givenName,
                          string surname = "Kannan", 
                          int age = 10)
{
      return givenName + " " + surname;
}

The second and third parameters, surname & age, both have default values. The only parameter required is givenName. To call this method you can either write this:


string name = null;
name = SomeMethod("Arjun");

That will return Arjun Kannan. You can also do this:


string name = null;
name = SomeMethod("FName", "LName");

The value returned is FName LName. But what if you didn't want to specify a surname but you did want to pass the age? You can do this by using named parameters:


string name = null;
name = SomeMethod("Rangoli", age: 20);

These are nice additions to the language.

List the Drives on your Computer using C#

2010-02-09T23:29:00.000-08:00

List the Drives on your Computer using C#?

Imagine you have two List. If you want to create a program to provide information about your Computer Drive, then use the System.IO.DriveInfo class.

The DriveInfo class can be used to determine the drives available on your computer, drive capacity, free space, type of drives etc. as shown below:


// Add namespace System.IO;

DriveInfo[] myDrives = DriveInfo.GetDrives();

foreach (DriveInfo di in myDrives)
{                
    Console.WriteLine(di.Name);
    if (di.IsReady)
    {
        Console.WriteLine(di.TotalSize);
        Console.WriteLine(di.DriveFormat);

        Console.WriteLine(di.AvailableFreeSpace);
        Console.WriteLine(di.TotalFreeSpace);

        Console.WriteLine(di.DriveType);
        Console.WriteLine(di.VolumeLabel);
    }
}

Compare Two List of Strings in C#

2010-02-09T23:26:00.000-08:00

Compare Two List of Strings in C#?

Imagine you have two List. You want to quickly compare them to see if all the elements match each other. Here's how to do so:


List<string> strList1 = new List<string>
{
    "Jack", "And", "Jill", "Went", "Up", "The", "Hill"
}; 

List<string> strList2 = new List<string>
{
    "Jack", "And", "Jill", "Went", "Down", "The", "Hill"
};

bool result = strList1.SequenceEqual(strList2);

How to check if a TCP port is blocked using C#

2010-02-09T23:23:00.001-08:00

How to check if a TCP port is blocked using C#?

In order to check if a TCP port is blocked, use the System.Net and System.Net.Sockets classes as shown below:


protected void Button1_Click(object sender, EventArgs  e)
{
      string host = "localhost";
      int port = 6900;
      IPAddress addr = (IPAddress)Dns.GetHostAddresses(host)[0];
      try
      { 
            TcpListener tcpList = new TcpListener(addr, port);
            tcpList.Start();
      }
      catch (SocketException sx)
      {
             // Catch exception here if port is blocked
      }
}

Convert Domain Name to IP Address

2010-02-09T23:17:00.000-08:00

How to convert Domain Name to IP Address in C#?

The answer is quiet simple. Just use the System.Net.Dns class


using System.Net;

protected void Page_Load(object sender, EventArgs e)
{
    foreach (IPAddress address in Dns.GetHostAddresses("www.youraddress.com"))
    {  
        Response.Write(address.ToString());
    }
}

Multiple Inheritance in C#

2010-02-09T23:11:00.000-08:00

C# supports single inheritance, however they do support multiple 'interface' inheritance:

Here's a sample demonstrating the same:


//Single Inheritance

public class A
{
    public A() { }
}

public class B : A
{
    public B() { }
} 


//Multiple Interface Inheritance

interface IComparable
{
    int CompareTo(object obj);
}

interface ISomethingElse
{
    int EqualTo();
}


public class Z :  IComparable, ISomethingElse
{
    public int CompareTo(object obj)
    {
        // implementation code goes here 
    }


    public int EqualTo()
    {
        // implementation code goes here 
    }
}

When I would need to create an interface when designing my application ?

2010-02-09T22:29:00.000-08:00

Question ...

When I would need to create an interface when designing my application ?

Short Answer...

When you want to abstract out what is required from how that requirement is met.

Full Answer...

The somewhat longer answer is to start with some of the premises of writing Clean Code:

Each method should be very short and do just one thing
Each class should have one easily articulated area of responsibility
Classes should know what other classes do but not how.

Let's look at how that might play out with an small example...

You might start off by refactoring into a Note class and a FileManager class like this:


using System.IO;
using System;

namespace Interfaces
{
   class Program
   {
      static void Main( string[] args )
      {
         var np = new NotePad();
         np.NotePadMainMethod();
      }
   }

   class NotePad
   {
      private string text = "Hello world";

      public void NotePadMainMethod()
      {
         Console.WriteLine( "Here I would interact with you and offer you 
a writing surface" );
         Console.WriteLine( "Then when you push the right button, 
I ask FileManager to " );
         Console.WriteLine("print the file..." );

         var fm = new FileManager();
         fm.Print(text);
      }
   }

   class FileManager
   {
      public void Print(string text)
      {
         Console.WriteLine( "I'm pretending to backup the old version of the file and then " );
         Console.WriteLine( " print the text you sent me " );
         Console.WriteLine( " printing {0}" , text );
         var writer = new StreamWriter( @"c:\temp\HelloWorld.txt", true );
         writer.WriteLine( text );
         writer.Close();
      }
   }
}

This console program is stripped of all error checking and all three classes are in one file to keep things simple. The idea is that the NotePad class interacts with the user, obtains a string to print, and then sends it to the FileManager whose job is to see if the file exists, if so make a backup, and then write the user’s text to the file (presumably we’d open a file save dialog rather than just assuming the user wants to write to c:\temp\HelloWorld.txt).

Adding A Second Writer

After creating the above, you realize that there will be times that you will want to write to, e.g., Twitter. You could put in a branching statement:


using System.IO;
using System;

namespace Interfaces
{
   class Program
   {
      static void Main( string[] args )
      {
         new NotePad().NotePadMainMethod();
      }
   }

   class NotePad
   {
      private string text = "Hello world";
         
      public void NotePadMainMethod()
      {
         var dest = "Twitter";
         switch ( dest )
         {
            case "File":
               var fm = new FileManager();
               fm.Print( text );
               break;
            case "Twitter":
               var tm = new TwitterManager();
               tm.Tweet( text );
               break;
         }
      }
   }


   class FileManager
   {
      public void Print(string text)
      {
         // write to file
      }
   }

   class TwitterManager
   {
      public void Tweet( string text )
      {
         // write to twitter
      }
   }
}

Adding An Interface

This begins to get ugly, and more important, the NotePad class is now entirely dependent on both the FileManager class and the TwitterManager class. It is cleaner, easier to maintain, and far easier to test, if we remove those dependencies.

The first step in doing so is to have the NotePad not know which class will take care of writing the message; all it needs to know is that some class that knows how to "Write" will do the work. We accomplish this by creating an interface, Writer that has a Write method.


interface Writer
{
   void Write(string whatToWrite);
}

We then have the FileManager and TwitterManager classes implement this interface:


class FileManager : Writer
{
   public void Write( string text )
   {
      // write to a file
   }
}

class TwitterManager : Writer
{
   public void Write( string text )
   {
      // write to Twitter stream
   }
}

At this point, we return to the NotePad and it can instantiate the class it wants as a Writer:


public void NotePadMainMethod()
{
   var w = new TwitterManager();
   w.Write( text );
}

That is step 1 in decoupling the NotePad from the other classes; now all it knows is that it has a Writer, which can be one or the other of the streams (or any other class that implements that method) but we’re hard coding which implementing class to use (in this case TwitterManager) in the NotePad class… not great.

Dependency Injection

Dependency Injection is one of those terms you really want to work into your conversation at every conference you attend. It marks you as a cutting edge, in the know kind of geek.

Here’s how it works. You don't want to hard-code the dependency into NotePad because that makes for code that is hard to maintain and hard to test.

What you can do, instead, is “inject” the dependency at run time. You can inject in a number of ways, the most common of which are:

Constructor injection
Property injection
Parameter injection
Using a Factory
Using an Inversion of Control (IoC) container

(Yes, IoC container may be even cooler than dependency injection. More on IoC below, but not much more)

1. Constructor injection just says that we’ll let the Notepad know which type of writer it is going to use when we create the class:


class NotePad
{
   private string text = "Hello world";
   private Writer w;
   public NotePad( Writer w )
   {
      this.w = w;
   }
      
   public void NotePadMainMethod()
   {
      w.Write( text );
   }
}

Notice that we pass in an instance of Writer, stash it away in a member variable and then NotePadMainMethod just uses it. The actual instance is not created in NotePad, it is created in whomever instantiates the NotePad and “injected” into NotePad through the constructor.

2. Property Injection works the same way, but instead of passing in the writer through the constructor, you set a property,


public Writer MyWriter { get; set; }
   
public void NotePadMainMethod()
{
   MyWriter.Write( text );
}

Now whoever instantiates MyWriter just sets the property and NotePad can take it from there.

3. Parameter Injection, as you can, by now imagine, eschews having a member variable, and just passes the type of writer into the method as a parameter


public void NotePadMainMethod(Writer w)
{
   w.Write( text );
}

10 Things to Consider Before You Send the Next Email

2010-01-24T21:14:00.000-08:00

10 Things to Consider Before You Send the Next Email

Email is the primary mode of communication between Internet users. You use email to network with other bloggers, to grow your online business, to convert potential prospects into clients and so on. The micro blogging sites like Twitter, Facebook may have changed the way we share information but when it comes in communicating with web users, email is probably the simplest and universally accepted option.

Having said that, it's obvious that you should pay attention to all those emails you send everyday. Here are a few tips for maintaining proper email etiquette:

1. Use a meaningful subject.

Just as a meaningful title makes a reader read a blog post, a meaningful subject of your email sets it apart from the crowd. A meaningful subject saves time as the recipient can grasp your idea quickly.

For example: If you want to post a guest article at Dailyblogtips and want to contact Daniel, use the subject line as "Guest article" rather than "Hello Daniel".

2. Skip the introductory paragraphs, jump directly to the point

When you are writing an email, keep the purpose in focus. Do not make the email longer by adding unnecessary introductions or links. The person whom you are writing the email may have dozens of emails to read and if you make the email long and boring, he will rather skip reading it.

Thus, avoid the boring intros and jump directly to your point. It saves time at both ends.

3. Use saved templates for answering commonly asked questions

If you get frequent emails where readers ask you the same questions, spend some time writing a template and save it in your drafts folder. Whenever you get a similar message to which you have replied before, just paste the template into the email message.

4. Add a human touch. Make it personal

I just said using templates to answer commonly asked questions. But do not overkill by making everything automated. There are some emails that will need your personal attention. So spend some time on them and try to provide some value. Not only you will get respect from the receiver, it also adds an impression that you care about your prospects.

5. Never write in capital case

WRITING AN EMAIL IN CAPITAL CASE makes it difficult to read and the receiver will get annoyed for sure. Hence, do not write an email in capital letters or else your message might end up in the trash folder.

6. Stick to the proper message thread

Including the earlier conversations in your reply is a good habit. The receiver might not remember the subject and the progress of each and every conversation. Hence an email without a thread will surely frustrate the receiver and he will have to spend some time searching for earlier threads of the conversation.

Gmail automatically includes the threads in your "reply" messages. Whenever you are replying to an email conversation always click "reply" instead of composing a new email message.

7. Read the email before you send it

Before you hit the send button, read what you have just typed. There may be spelling and grammatical mistakes which might have slipped through. Try to read the email from the receivers angle and see if it delivers the same meaning which you are trying to convey.

8. Don’t use abbreviations, slang and emoticons

Business emails should be formal as they reflect the posture of your organization or company. If you lower the weight of your business email by adding lots of abbreviations and smilies (e.g., LOL and :) - smiles ), chances are there that your clients won’t take you seriously.

9. Be careful with formatting

Do not try to decorate your email message with lots of colors and formatted stuff. If you unnecessarily highlight text, the email can appear to be spammy. As a general rule, use black color on a white background.

10. Use short and simple sentences

Email’s should be simple to read and should convey the meaning as quick as possible. Never think that if your writing is Shakespearean, the recipient will take interest in reading it. Keep the sentences short and simple and never write an email when you are angry – it reflects.

Do you take care of all of the above mentioned emailing habits ? Let us know through the comments section.

Hope this will be useful.

Checkbox Validation using jQuery?

2010-01-22T01:16:00.000-08:00

How to validate the checkbox using Jquery?

In the HTML form have multiple chekcbox in same using html array element. That time we will use three types of checkbox validation for checked or not.

Multiple checkbox validation has three types.

Checkbox validation using Id
Checkbox validation using name
Checkbox validation using div tag

Let we see via examples:

Take the below html/aspx code likes ...


<form>
    <div id="checkboxId">
    <input type="checkbox" name="chkBox[]" id="chkBox[]">
    <input type="checkbox" name="chkBox[]" id="chkBox[]">
    <input type="checkbox" name="chkBox[]" id="chkBox[]">
    </div>

    <input type="button" name="Btnaction" 
value="submit" onclick="return validateId();">
</form>
</div>

// Calling jquery file.
<script language="javascript" src="jquery.js" type="text/javascript"></script>

1. Checkbox validation using Id


<script language="javascript">
function validateId()
{
    var selector_checked = $("input[@id=chkBox]:checked").length;
    alert(selector_checked);
    if (selector_checked == 0)
    {
        return false;
    }
    else if (selector_checked == 0)
    {
        return false;
    }
    else
    {
        return true;
    }
}
</script>

2. Checkbox validation using Name

Replace the function name from 'validateId' to 'validateName' in the above html/aspx code.


function validateName()
{
    var selector_checked = $("input[@name=chkBox]:checked").length;
    alert(selector_checked);
    if (selector_checked == 0)
    {
        return false;
    }
    else if (selector_checked == 0)
    {
        return false;
    }
    else
    {
        return true;
    }
}

3. Checkbox validation using Div tag

Replace the function name from 'validateName' to 'validateDiv' in the above html/aspx code.


function validateDiv()
{
    if($("#checkboxId input[type='checkbox']:checked").length > 0)
    {
        return true;
    }
}

4. Single checkbox validation.


<div>
        <input type="checkbox" name="chkBox[]" id="chkTCAgree" />Agree terms and condition
        text here<br />
        <input type="button" name="Btnaction" value="submit" onclick="return validateTC();" />
    </div>

 function validateTC() {
            var agree = $('#chkTCAgree').attr('checked');
            if (!agree) {
                alert("please accept the terms and conditions");
                return false;
            }
        }

Enjoy the technology!

Free ebook - Accelerated C# 4.0

2010-01-18T23:22:00.000-08:00

Accelerated C# 4.0 Description

C# 2010 offers powerful new features, and this book is the fastest path to mastering them—and the rest of C#—for both experienced C# programmers moving to C# 2010 and programmers moving to C# from another object-oriented language.

Many books introduce C#, but very few also explain how to use it optimally with the .NET Common Language Runtime (CLR). This book teaches both core C# language concepts and how to wisely employ C# idioms and object-oriented design patterns to exploit the power of C# and the CLR.

This book is both a rapid tutorial and a permanent reference. You’ll quickly master C# syntax while learning how the CLR simplifies many programming tasks. You’ll also learn best practices that ensure your code will be efficient, reusable, and robust. Why spend months or years discovering the best ways to design and code C# when this book will show you how to do things the right way from the start?

Comprehensively and concisely explains both C# 2008 and C# 2010 features
Focuses on the language itself and on how to use C# 2010 proficiently for all .NET application development.
Concentrates on how C# features work and how to best use them for robust, high-performance code

What you’ll learn

How C# works with and exploits the CLR
How to use arrays, collections, and iterators
How to handle events with delegates and anonymous functions
How to design and use generic types and methods
How to thread efficiently and robustly
How C# anonymous types, lamba expressions, and extension methods work and how to use them

ASP.NET 4 Page Life Cycle

2010-01-18T04:37:00.000-08:00

When an ASP.NET 4.0 page runs, the page goes through a life cycle in which it performs a series of processing steps. These include

initialization
instantiating controls
restoring and maintaining state
running event handler code and
rendering.

It is important for you to understand the page life cycle so that you can write code at the appropriate life-cycle stage for the effect you intend.

The following diagram shows some of the most important methods of the System.Web.UI.Page class that you can override in order to add code that executes at specific points in the page life cycle.

It also shows how these methods relate to page events and control events. A preliminary version of the diagram was added to the ASP.NET 4 Beta 2 page life cycle documentation on MSDN.

Use the technology. Happy Coding...!

Removing non ASCII characters in C#

2010-01-18T03:06:00.000-08:00

Its one of the C# Tip....

Removing non ASCII characters in C# by using the regular expression.

To make sure you clean your string from non ASCII characters you can use Regex class instead of using string functions. The [\x01-\x1F] is the range you want to keep.


temp = Regex.Replace(temp, "[\x01-\x1F]", "");

Happy coding...

New Year Wishes - Year 2010

To my ever tolerant my friends and relatives, available round the clock for valuable support and guidance, and to all those who are very close to my heart, here is a special note, exactly a day before yet another sunrise in our life that'd see us replace one more calendar with a brand new one, quite symbolic to our mind's act of replacing unfullfilled dreams and promises with new ones and to give it all a fresh beginning.

GOOD BYE my 2009.

Here's wishing all a very happy, peaceful and prosperous New Year 2010.

What is an ASHX file Handler or web handler ?

2009-12-31T04:19:00.000-08:00

In ASP.NET, you probably spend most of your time creating .aspx files with .cs files as code behind or use .ascx files for your controls and .asmx files for web services.

A web handler file works just like an aspx file except you are one step back away from the messy browser level where HTML and C# mix. One reason you would write an .ashx file instead of an .aspx file is that your output is not going to a browser but to an xml-consuming client of some kind.

Working with .ashx keeps you away from all the browser technology you don't need in this case. Notice that you have to include the IsReusable property.

What does the code there do?

It defines two parts of the IHttpHandler interface. The important part is ProcessRequest(), which will be invoked whenever the Handler.ashx file is requested or pointed to.


<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;

public class Handler : IHttpHandler
{
   public void ProcessRequest(HttpContext context)
   {
       context.Response.ContentType = "text/plain";
       context.Response.Write("Hello World");
   }

   public bool IsReusable
   {
       get
       {
           return false;
       }
   }
}

Using query strings:

Developers commonly need to use the QueryString collection on the Request. You can use the Request.QueryString in the Handler just like you would on any ASPX web form page.


<%@ WebHandler Language="C#" Class="QueryStringHandler" %>

using System;
using System.Web;

public class QueryStringHandler : IHttpHandler
{
   public void ProcessRequest (HttpContext context)
   {
       HttpResponse r = context.Response;
       r.ContentType = "image/png";
       string file = context.Request.QueryString["file"];
       if (file == "Arrow")
       {
           r.WriteFile("Arrow.gif");
       }
       else
       {
           r.WriteFile("Image.gif");
       }
   }

   public bool IsReusable
   {
       get
       {
           return false;
       }
   }
}

Now Debug the application:

When you pass Fille='Arrow' in query string like as follows

http://localhost:1372/FileHandler/QueryStringHandler.ashx?file=Arrow
You will get the output with arrow image. Otherwise you will get output as image.

http://localhost:1372/FileHandler/QueryStringHandler.ashx?file=Image

The above code receives requests and then returns a different file based on the QueryString collection value. It will return one of two images from the two query strings.

When we use Handler:

Here I want to propose some guidelines about when to use custom handlers and when to use ASPX web form pages. Handlers are better for binary data, and web forms are best for rapid development.

Use web forms (ASPX) when you have:

Simple HTML pages
ASP.NET custom controls
Simple dynamic pages

Use handlers (ASHX) when you have:

Binary files
Dynamic image views
Performance-critical web pages
XML files
Minimal web pages

Hope this will be useful.

How to highlight the GridView rows when the mouse moves over it

2009-12-21T02:42:00.000-08:00

In ASP.NET, in order to add a TextBox to the GridView you will need to add a Template Column. In most of the cases I suggest that you use the Template Column instead of the Bound Column.

The reason is that by using the Template Column you can refer to the column by finding the control which exists inside the column. Bound Column works by using indexes which means that if later you add another column and change the columns placement then you will need to change all the columns respectively.

Take a look at the code below which adds Template Columns to the GridView.

We need to highlight the row when the focus is on the TextBox. For this we can attach a simple client side event to the TextBox which is called "onFocus". The onFocus event is fired whenever a focus is made on the control. Take a look at the code below which demonstrate how to add the onFocus event to the TextBox control.


 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BackColor="White"
            BorderColor="#CCCCCC" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" Font-Names="Verdana"
            Font-Size="Small" Width="300px">
            <FooterStyle BackColor="White" ForeColor="#000066" />
            <RowStyle ForeColor="#000066" />
            <Columns>
                <asp:ButtonField CommandName="Select" Visible="false" />
                <asp:BoundField DataField="RowNumber" HeaderText="S.No" InsertVisible="False" ReadOnly="True"
                    Visible="true" SortExpression="RowNumber" />
                <asp:TemplateField HeaderText="Name">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox1" onBlur="ResetColor()" onFocus="ChangeColor()" TabIndex="1"
                            Text='<%#Eval("FirstName")%>' runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Name">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox1" onBlur="ResetColor()" onFocus="ChangeColor()" TabIndex="1"
                            Text='<%#Eval("Address")%>' runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Delete">
                    <HeaderStyle HorizontalAlign="Center" Width="6%" VerticalAlign="Middle" />
                    <ItemStyle HorizontalAlign="Center" Width="6%" VerticalAlign="Middle" />
                    <ItemTemplate>
                        <asp:ImageButton ID="btnDelete" OnClientClick="return confirm('Do you want to delete this record?');"
                            CommandName="DeleteRow" AlternateText="Delete" runat="server" CommandArgument='<%# Eval("RowNumber") %>'
                            ImageUrl="icon_delete_grid.gif"></asp:ImageButton>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
            <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
            <SelectedRowStyle BackColor="Yellow" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
        </asp:GridView>

Include the javascript function on the page :


<script type="text/javascript">
     var oldRowColor;
    function ResetColor()
    {
        var obj = window.event.srcElement;
        if(obj.tagName == "INPUT" && obj.type == "text")
        {
            obj = obj.parentElement.parentElement;
            obj.className = oldRowColor;
        }
    }    

    // this function is used to change the backgound color
    function ChangeColor()
    {
        var obj = window.event.srcElement;
        if(obj.tagName == "INPUT" && obj.type == "text")
        {
        obj = obj.parentElement.parentElement;
        oldRowColor = obj.className;
        obj.className = "HighLightRowColor";
        }
    }    
    </script>

Include the style into the page


<style type="text/css">
        .RowStyleBackGroundColor
        {
            background-color: #FFFBD6;
        }
        .RowAlternateStyleBackGroundColor
        {
            background-color: White;
        }
        .HighLightRowColor
        {
            background-color: Yellow;
        }
    </style>

Finally, add the code behind code (sample given here is based on C#)


protected void Page_Load(object sender, EventArgs e)
        {
            DummyData();
        }

        private void DummyData()
        {
            DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
            DataRow drCurrentRow = null;

            //Store the current data to ViewState
            DataTable dt = new DataTable();
            DataRow dr = null;
            dt.Columns.Add(new DataColumn("RowNumber", typeof(string)));
            dt.Columns.Add(new DataColumn("FirstName", typeof(string)));
            dt.Columns.Add(new DataColumn("Address", typeof(string)));
            for (int i = 1; i <= 5; i++)
            {
                dr = dt.NewRow();
                dr["RowNumber"] = i;
                dr["FirstName"] = "Test Name " + i;
                dr["Address"] = "Test Address " + i;

                dt.Rows.Add(dr);
            }
            ViewState["CurrentTable"] = dt;

            //Rebind the Grid with the current data
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }

Now, run the application and focus on one of the TextBoxes and the appropriate row will be highlighted. The result should be like below :
