Hi dude...
try it...
=========================================================
function checkFileExtension(elem) {
var filePath = elem.value;
if(filePath.indexOf('.') == -1)
return false;
var validExtensions = new Array();
var ext = filePath.substring(filePath.lastIndexOf('.') + 1).toLowerCase();
validExtensions[0] = 'txt';
validExtensions[1] = 'doc';
validExtensions[2] = 'rtf';
for(var i = 0; i < validExtensions.length; i++) {
if(ext == validExtensions[i])
return true;
}
alert ('You Cant upload a '+ext.toUpperCase()+' file!');
return false;
}
============================================================

You can't do this, other than using javascript to check the filename extension as someone else mentioned.

I recently installed IIS on my home machine running XP Pro so I could start learning to develop web sites. I'm trying to use the Club Site Kit. When I ran it from files d:\ClubSite it ran fine but after installing IIS and using http://localhost/ClubWebSite to host it, when I run it I get the following error;
Server Error in '/ClubWebSite' Application.
Failed to access IIS metabase.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.Hosting.HostingEnvironmentException: Failed to access IIS metabase.
I've spent all day googling and dinking around to try and configure IIS to work but I don't have much hair left to pull out!
Any help or links would be much appreciated.

Thanks it worked like a charm.
I used the -i option and it got me past that point.
I got it working on my machine but I have another computer running server 2003 and having other problems there. But I want to do some research so I can ask intelligent questions. As I said I'm just starting to do Web development and at the moment its a bit overwhelming.
Thanks for your help I really appreciate it.

I think so this will help you to resolve your issue
an Exp. is here
Write down some text in TextBox and Click On link It'll change tool tip for Text box what Text you entered in Text Box
JavaScript Function:
function HelloToolTip(v){
document.getElementById(v).title = document.getElementById(v).value;
}
Html Code Here:
<table>
<tr><td>
<a href='#' onclick="javascript:HelloToolTip('<%=txt.ClientID%>')>Change ToolTip</a>
</td>
<td>
<asp:TextBox id="txt" runat="server"/>
</td>
</tr>
</table>

Double post = no help.
Read the forum guidelines. You claim to be a university graduate but you can't follow simple instructions? How do you expect to be able to hold down a career in the technology industry if you can't do that?

Do NOT post the same question in multiple forums. Doing so is considered very rude around here and on other sites as well. And, as you've found out, it doesn't get your question answered any faster.

Hi All,
I'm trying to get feedback from others who have experience with online stores (shopping cart applications).
I'm soliciting bids for a web site design. I desire one database. The one database should handle customer information/orders. In addition, I want support and other information to exist in the database. My experience has been less than desireable when splitting databases.
The sales teams I am speaking with keep telling me it is not possible - customer information/sales is different than support. I don't understand why. Perhaps because of a 'canned solution'?
What I don't want to do is have a second database, duplicating information from the first. What has others experience been? I don't feel I am asking for too much here.

I don't see how that can be. Customer information is needed in order to provide support

Do you not know how to use Google? You will find plenty of information if you bother to search.
Also, don't just ask for code. It's rude, and makes you look like another lazy, stupid Indian developer who isn't capable of doing their job.
