Getting Started with NuGet Packages step by step overview.

We can all see lots of buzz about NuGet in asp.net world. So I decided to explore it. let’s explore it in some details. Following is a explanation of NuGet Extension on the code plex here.


"NuGet is a Visual Studio extension that makes it easy to add, remove, and update libraries and tools in Visual Studio projects that use the .NET Framework. When you add a library or tool, NuGet copies files to your solution and automatically makes whatever changes are needed in your project, such as adding references and changing your app.config or web.config file. When you remove a library, NuGet removes files and reverses whatever changes it made in your project so that no clutter is left."

For that first you have to go thorough the Tools->Extension Manager and then search for nuget and it will appear in …

Programmatically creating asp.net request and handling response

Recently one of the my friends asked about how to create a web request in asp.net to a url outside of project. So I decided to write a small blog post regarding this. This web request can be easily created with httpwebrequest class and you can easily consume the response we are getting from this. This kind of request can be very useful when you are implementing payment gateways or other third party components. Following is a code for it. It is very easy.using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.IO;

namespace Experiment
{
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string url = "http://localhost:1798/WebForm2.aspx";
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.Method = "POST";

Let’s investigate one of great features that Microsoft has given with Visual Studio 2010.What is code snippets?Code snippets is a one of the cool feature that given in Visual Studio IDE. If you know the chunks of the code that you need to type over and over again throughout the code then this code snippets feature will help you on this. For example your exception handling code. Your redirection code everything you need more can be putted in the code snippets.You can insert code snippets via right click –> Insert code snippets and there is also a short code is also available to bring up directly code snippets via pressing ctrl-K+ ctrl-X.

HTTP Module in details

I know this post may sound like very beginner level. But I have already posted two topics regarding HTTP Handler and HTTP module and this will explain how http module works in the system. I have already posted What is the difference between HttpModule and HTTPHandler here. Same way I have posted about an HTTP Handler example here as people are still confused with it. In this post I am going to explain about HTTP Module in detail.What is HTTP Module?As we all know that when ASP.NET Runtimes receives any request it will execute a series of HTTP Pipeline extensible objects. HTTP Module and HTTP handler play important role in extending this HTTP Pipelines. HTTP Module are classes that will pre and post process request as they pass into HTTP Pipelines. So It’s one kind of filter we can say which will do some procession on begin request and end request. If we have to create HTTP Module we have to implement System.Web.IHttpModule interface in our custom class. An IHTTP Module contains two m…

Converting a generic list into JSON string and then handling it in java script

We all know that JSON (JavaScript Object Notation) is very useful in case of manipulating string on client side with java script and its performance is very good over browsers so let’s create a simple example where convert a Generic List then we will convert this list into JSON string and then we will call this web service from java script and will handle in java script.To do this we need a info class(Type) and for that class we are going to create generic list. Here is code for that I have created simple class with two properties UserId and UserNamepublic class UserInfo { public int UserId { get; set; } public string UserName { get; set; } } Now Let’s create a web service and web method will create a class and then we will convert this with in JSON string with JavaScriptSerializer class. Here is web service class.using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; namespace Experiment.WebService { /// <summary> /// Su…

Distinct operator in Linq

Linq operator provides great flexibility and easy way of coding. Let’s again take one more example of distinct operator. As name suggest it will find the distinct elements from IEnumerable. Let’s take an example of array in console application and then we will again print array to see is it working or not. Below is the code for that. In this application I have integer array which contains duplicate elements and then I will apply distinct operator to this and then I will print again result of distinct operators to actually see whether its working or not. using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Experiment
{
class Program
{
static void Main(string[] args)
{
int[] intArray = { 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5 };
var uniqueIntegers = intArray.Distinct();
foreach (var uInteger in uniqueIntegers)
{
Console.WriteLine(uInteger);
}
Console.ReadK…

ASP.NET 4.0- Html Encoded Expressions

We all know <%=expression%> features in asp.net. We can print any string on page from there. Mostly we are using them in asp.net mvc. Now we have one new features with asp.net 4.0 that we have HTML Encoded Expressions and this prevent Cross scripting attack as we are html encoding them.ASP.NET 4.0 introduces a new expression syntax <%: expression %> which automatically convert string into html encoded. Let’s take an example for that.I have just created an hello word protected method which will return a simple string which contains characters that needed to be HTML Encoded. Below is code for that.protected static string HelloWorld()
{
return "Hello World!!! returns from function()!!!>>>>>>>>>>>>>>>>>";
}
Now let’s use the that hello world in our page html like below. I am going to use both expression to give you exact difference.<form id="form1" runat="server">
<div>

.NET Framework 4.0-Guid.Parse Method

In earlier version of .NET framework we don’t have Guid.Parse method Now we have an Guid.Parse method in .NET Framework and it’s work like any parse method. Let’s see it by an example. Let’s create console application for that.class Program
{
static void Main(string[] args)
{
string newID = "f718943d-757d-4975-947b-3dbff1205be6";
Guid myGuId = Guid.Parse(newID);
Console.WriteLine(myGuId.ToString());
Console.ReadLine();


}
}
and as expected here is the out put for that.
That’s is it’s cool. Stay tuned for more..Happy programming..

Creating an HttpHandler to handle request of your own extension

I have already posted about http handler in details before some time here. Now let’s create an http handler which will handle my custom extension. For that we need to create a http handlers class which will implement Ihttphandler. As we are implementing IHttpHandler we need to implement one method called process request and another one is isReusable property. The process request function will handle all the request of my custom extension.so Here is the code for my http handler class.using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; namespace Experiement { public class MyExtensionHandler:IHttpHandler { public MyExtensionHandler() { //Implement intialization here } bool IHttpHandler.IsReusable { get { return true; } } void IHttpHandler.ProcessRequest(HttpContext context) { string excuttablepath = context.Request.AppRelativeCurrentExecutionFilePath; if (excuttablepath.Contains("HelloWorld.dotnetjalps")) { Page page = n…
