Thank u Jesse.
I proceded as u have guided and the outcome is good, but now my program only distinguishes between authenticated user and anonymous users. I need a method from which I can know whether the said user is a subscriber to that document or not.
Now suppose a situation can be created like this:-
A person X has subscribed a document "abc.doc" now X is able to see the document and also can see the full URL. Now if he copy the url and give it to other person Y. Then Y can do these steps to see the document
1)Login
2)paste the url given by X
Then he will be able to see the document, even if Y is not a subscriber to that document.
Please help to rectify this.
Thank U.

I'm afraid that I don't see a quick answer to this. You're going to have to come up with a security strategy. You will need to set up some kind of way to distinguish who has access to a given document. There are a couple of strategies that come to mind.
If you find that document permissions are grouped in some kind of pattern, then you will probably want to consider a role-based[^] security solution. Basically, what this means is that you'll define the general groups that the documents fall into, and associate a user with each group. The search that I linked has tons of good examples. I'd start with Heath Stewart's article[^] here on CodeProject.
If you can't discern any grouping patterns, then you will most likely have to devise a system of associating a user with an individual document. The easiest approach that I can think of to do so would be a simple table in a database that matches the user id and the document id.
Hope that helps a bit.

Technically, I believe it would work. However, I wouldn't advocate it as written for heavy use with large files. The drawback to my code is that the files being passed through the HttpHandler are being read into memory then dumped to the response buffer.
For your purposes, I spend a bit more time looking into securing that directory. You're not the first person to tackle this, so I'd have to imagine that sifting through Google may yield some gems.
If you were interested in experimenting a bit, you could try more of a streaming approach to the HttpHandler. You could use the same basic method, but instead of reading the entire file, use a binary reader to get a chunk of bytes, pass it to the response string, flush the response buffer, and repeat until done. That should lower the memory footprint [may also impact the speed a bit]. The disclaimer here is that I'm throwing an idea off the top of my head. I haven't tried it, but it may be worth some experimentation. If you do decide to go this route, please check in and let me know the results.
Best of luck.

You can't access web server controls from Javascript. They only exist on the server and are used to produce the html code of the page. When the page reaches the browser, the server controls no longer exist.
Some server controls procude an html element that directly correspond to the server control. In that case you can access that element from Javascript code.
As a RadioButtonList does not correspond to a single element in the html code, there is no single element that you can access from Javascript.

You'll probably find that the control is prefixed with "_ctl0_" - since it's in a usercontrol.
The simplest way to find out is to turn on Tracing at the top of the page, and make sure that the full client ID of the control is what you expect it to be - having said that, I use the MS IE Developer Toolbar - worth its weight in gold in my book!

Is there anyone having good example for windows service to asp.net page. i want to send weekly and monthly reports but it should done automatically when system starts. Thanks.

Not quite sure what you mean by this - a service can't talk to a web page, and vice versa - a service just sits there running all the time....
If the service is coded correctly, then it can be set to auto start with the OS, but this has nothing to do with ASP.
If you want a webform to collect data to give to a service that is scheduled to run at specific times, then you'll have to use an intermediary database, or my personal fave - MSMQ

Hello,
I started to work with Atlas and I use the Sys.UI.AutoCompleteBehavior.
I need to extend it and to override one of its methods.
I will appricaite if someone will tell me how to do it.
What I did is:
1 - I created a .js file with:
Type.registerNamespace('My.Sys.UI');
My.Sys.UI.MyAutoCompleteBehavior = function () {
My.Sys.UI.MyAutoCompleteBehavior.initialize(this);
}
this.initialize = function() {
My.Sys.UI.MyAutoCompleteBehavior.callBaseMethod(this,'initialize');
}
this.dispose = function() {
My.Sys.UI.MyAutoCompleteBehavior.callBaseMethod(this,'dispose');
}
My.Sys.UI.MyAutoCompleteBehavior.registerSealedClass('My.Sys.UI.MyAutoCompleteBehavior',Sys.UI.AutoCompleteBehavior);
Sys.TypeDescriptor.addType('script','MyAutoCompleteBehavior', My.Sys.UI.MyAutoCompleteBehavior);
and then instead of using:
<behaviors>
<autoComplete
.....
...../>
<behaviors>
I used:
<behaviors>
<autoComplete
.....
...../>
<behaviors>

Seems you didn't say what you might want to extend, or what happens with your sample code.

I want to extend the _setText method (I didn't put it in my code yet)
and I get Object doesn't support this property.
