Use this line that you have commented out

'Dim dirInfo As New DirectoryInfo(Server.MapPath("/Upload"))

Hi

The risen i have done that is bc i get the same error/blank page, so no luck with that..

Nasir Razzaq

I have just tested your code in my sample web app and it works fine. Just make sure you are using the correct path and that ASPNET user has access to that path.

Where do i setup the ASPNET user Access !?

Nasir Razzaq

Right click on folder and security tab. Is it using the anonymous IIS user or are you using windows authentication?

Nasir Razzaq

If anonymous then also give iis_usr user permissions.
