Writing Your Own HttpHandler
0 commentsHi All,
Today i'll explain how to write our own handler for a new kind of page. Firstly, Handlers(as the term explain) are for handling things. These things are client requests. So for a client request to Default.aspx there will be a handler. This will be a default handler which will ship along with asp.net runtime. If you have new kind of extension you can writer your own handler.
The reason of writing this blog is for a good understanding of http handlers. I insist you to follow these steps and create your own handler. I have followed these procedures from the site:
http://www.15seconds.com/Issue/020417.htm
Step 1:
In u r VS, create a new c# class library and the name the class as MyOwnHandler.
The code should be
using System;
using System.Web;
using System.Text;
namespace MyCustomizedHandler
{
public class MyOwnHandler: IHttpHandler
{
public MyOwnHandler()
{
}
#region for implementing HttpHandler
Public void ProcessRequest(HttpContext context)
{
HttpResponse responseObject = context.Response;
responseObject.Write("<html><body><h1>My Customized page</h1>");
responseObject.Write("</body><html>");
}
Public bool IsReusable
{
get
{
return true;
}
}
#endregion
}
}
}
Rather than copying and pasting i insist all of u to type this small piece of code manually. Now just compile this from ur VS and paste the output of this dll into a virtual folder webapplication. I have a website in my iis with the name 'jsonSamples', so i placed the dll output of the above code into the bin directory of 'jsonSamples'.
Step2:
Now open the web.config file of the webapplication(in my case 'jsonSamples') and add the following piece of code inside it:
<add verb="*" path=".sample" type="MyCustomizedHandler.MyOwnHandler, MyCustomizedHandler">
</httpHandlers>
Step3:
All what we have done is in the application level. i.e., our application knows how to render a request for the page type .sample. Now we have to tell this to the iis webserver also. For that we have to do:
Launch IIS, right click on Default Web Site, go to home directories tab, click on configuration. This will open a new window. Now click on the add button and in the Executable section give the url of the aspnet_isapi.dll. Down to it, the extension should be given as 'sample'.
Click all ok's and close the window.
Now from ur browser just make a request some thing like this:
http://localhost/jsonSamples/helllo.sample
http://locahost/jsonSamples/239kshrkweh.sample
http://localhost/jsonSamples/anything.sample
You should get the output. (But i didn't get the output for the first time)
If u dont get the output then dont panic, just open ur webapplication(jsonSamples) in VS and for it add reference of u r class library dll. Even though u have placed the dll in the bin directory of the webappliation but u need to do add reference to the same item once again from VS. I dont know why but it works.
Hope this helped.

List all Running Applications through windows script
0 commentsHi All,
The following is a simple script which will list all the applications inside ur taskmanager applications tab.
Set objWord = CreateObject("Word.Application")
Set colTasks = objWord.Tasks
For Each objTask in colTasks
If objTask.Visible Then
Wscript.Echo objTask.Name
End If
Next
objWord.Quit
Must and should read link:
Infact i actually copied the above code from this link only. This was really very helpful and it explained me a lot. I'd simply like to say: "All the processes which are not running in hidden mode are listed in the applications tab.If a process doesn't have a visible window then it will not be present in the applications tab."
I really insist all of u to go through the above link for a better understanding of things.

Open Yahoo Mail through Windows Script
0 commentsHi People,
I'm a Newbie to scripting world. I thought of writing a windows script which will take my credentials and automatically logs me into yahoo. With lots of googling i m able to write the following code:
set objIE = CreateObject("InternetExplorer.Application")
objIE.Navigate "www.mail.yahoo.com"
objIe.Visible = true
'wait untill page gets loaded
While objIE.busy
WScript.Sleep 1000
Wend
objIE.document.getElementByID("username").value = "my_username"
objIE.document.getElementByID("passwd").value = "my_password"
objIE.document.getElementsByName(".save")(0).click()
That's it. Copy and paste the above code. Yeah pls fill corresponding username and password fields. This code needs to be worked in the following sections:
1)Inside the if condition i m finding the username textbox through DOM selection and then filling in the appropriate fields. But this may affect if the textbox name changes.
The following are some of the links where u can find some more useful information:

CSS Tips
0 commentsThe disadvantage of using table-layout is, once the entire table is loaded then only u can view it. This is a performance issue interms of user experience, for ex if u have table with hundred images, until all the images r loaded u cannot see them. Instead if u follow some other way like using div's, it might be good.
Also dont overwrite styles until unless they r explicitly required. This is because if u have color coming for a p element from two style rules then it is considered as an error in css validator checks.
Giving negative margins will mess up things in IE6.

Nullable Types in C#
0 commentsint x = 0; //valid statement
int y = null; //compile time error
This is because we know that null is a value for reference types and since int is a value type it cannot hold the value null in it. So if there comes a situation where u need to hold null value inside an int then the solution is the Nullable Type.
Any Value Type can be Nullable Type, which means that the default value can hold the possible value in its data range as well as a new value 'null' in it. The syntax for this is,
int? x = null; //valid statement; now x is a nullable type
Also dont guess that since now x can hold null value, it can be reference type. This is wrong. What Nullable Type is like a wrapper around a value type which can hold a null value also. So the value of x is stored in stack(by default).
