Iterator blocks are called when you want to fetch the data from the Enumerable.

Actually if you call the the function, it will not be called. Rather if you do a foreach on the Enumerable object the function will be called and will return you 10. Wink | ;)

Just change your code a bit as I did:

IEnumerable<int> arr = Documented.GetValuesUpto(10);
MessageBox.Show(arr.ToList<int>().Count.ToString());

public static IEnumerable<int> GetValuesUpto(int n)
{

    for (int ctr = 1; ctr <= n; ctr++)
    {

       yield return ctr;
    }
            
}

Put a breakpoint in the line IEnumerable<int> arr = Documented.GetValuesUpto(10);. and also a breakpoint within GetValueUpto block. You will see the function is called when we try to call ToList() rather than the actual call to GetValueUpto. This is the main advantage of iterator blocks.

Hi ,
I found the solution for finding the cursor position in the textarea . i have used it in my numberbox.

@Abhishek Sur : thanks for the link , i found some useful stuff there which was useful.

Solution is :

<br />
                // initialize cursor position<br />
                var Curpos=-1;<br />
                //Firefox code <br />
                Curpos = srcElement.selectionStart;<br />
                //IEcode code<br />
                if (Curpos!=-1){<br />
                if( document.selection ) { <br />
                r = document.selection.createRange();<br />
                r.moveStart('character', -myString.length); <br />
                Curpos =r.text.length;<br />
                }   <br />
                }<br />
<br />
<br />
<br />

Thanks and Regards,
Sriharsha

Ajax Refresh Without Timer

Hello,
I am Developing a Web-Chat Application using ASP.Net with c# language. For chat window updation I am using

AJAX Panel and updation happen for every 1 second as the Timer control Interval given in Timer is 1 Second.

Updation code is implemented in Timer_Tick().
I feel is for every frequent time interval updation happens which can cause unnecessary load on the server.

Basically for chat application only when send button is clicked updation is needed. I feel AJAX Refresh is not needed when the user is idle i.e when the user doesn't click on send button.

My Query is it possible to refresh all the webpages of this particular link opened in different PC's when any user clicks on Send Button. What can i do for similar Implementation. If my query is not clear please
feel free to ask questions.

So if you chat to me, I won't see it until I click a button ? Sounds like crap to me

No. There's no way this can work, that's why you're using a timer.

Just do

if(Request.Session["yourkey"] == null)
linkbutton2.visible = false;
else
linkbutton1.visible = false;

But you must be careful to this, as Asp.NEt doesnt renders visible=false controls to the client. Thumbs Up | :thumbsup:

Otherwise you can use display:none style entry to the control Style property.

Problem I'm having is with the CSS Styling. I'm using a .ascx control and I've linked the CSS into that but it doesn't style the Accordion. At one point it was styling it on load then as soon as i clicked a Link Button the styling would disapear, now the styling doesn't appear at all.

Any help would be greatly appreciated.

You can rather use a regular expression validator.

Web application with unamnaged DLL calls

I've got web application that calls to unmanaged DLL. For simplicity there is a function that just returns immediatly.

From VS it runs normally both in debug and release builds.

After web application linked in IIS7.0 unmanaged debug DLL version still runs from web project, but when the release build unmanaged DLL is put, it hangs after web application invokes unmanaged function, as I traced the cs code, and never returns.

What might be the problem?

are you running from web server?

If you are using file:// protocol, means directly opening a file from hard disk, you will be prompted to have script block issue.

This will not happen if you publish your file. If still javascript is not running, check the path of the script file properly. always use relative path to your server.

Also place a <noscript> tag to check if javascript is disabled.

Hope this helps you. Thumbs Up | :thumbsup:
