Actually I want to allow only number in a textbox not alphabets. The code which I have posted is accepting both and also special symbols. I can just see on the status bar that error in script.

Please help me in doing this...

I just ran the script you have me on FireFox 2.0 and IE7 and it works absolutely fine. You must have Javascrip enabled because of the error.... I ave not idea what the problem could be....
What browser are you using?

You are using evt and event. The evt object is null in IE6. Try this:

function isNumberKey(evt)
      {
         if(!evt) evt = event;  
         var charCode = (evt.which) ? evt.which : evt.keyCode
         if (charCode > 31 && (charCode < 48 || charCode > 57))
            return false;

         return true;
      }

In IE(6) an event function does not receive any parameters.

Yahoo Mail Beta File Upload

Hi,

Anyone knows how the Yahoo Mail Beta does the File Upload technically? It is clear that it does not use FileUpload control from ASP.NET 2.0 for sure or HtmlInputFile HTML control.

Thanks,

Capricron

One would imagine that Yahoo is not using ASP.NET for its its mail beta (or indeed any of its sites)....although I could always be wrong.

I think they use Perl-CGI or PHP since their servers are mostly OpenBSD or Linux.

The reason why I am interested in knowing it is because I like the way that it allows opening the "Choose file" window directly. If using HtmlInputFile or FileUpload, I have to create another page that the control to open the "Choose file" window by clicking the "Browse" button. It is nice to open the "Choose file" window by just clicking the "Attach" button on the page. Is it possible to make it work using Javascipt+ASP.NET?
