What does it mean ? Are you getting any error ? or what ?

You are talking about Hosting on IIS or Running your Application From Visual Studio ?

Yes ! That's why I asked you the question, what is the problem Smile | :)

if you are hosting on server, you have to give Write Access permission to that folder where you are uploadinf the file.

Always rememebr this rule of thumb:

Everyapplication can have one and only one Main function.

Search in your code, it looks that there are multiple main functions are defined.

This has nothing at all to do with ASP.NET. You want the C# forum. You should work through a basic book rather than trying to copy code off the web.
