Re: File Download from Network Share

Hi! Patrice,

Thanks for the response. I am using filestream to read the file like
Dim strFilePath As String

It's working fine when i am viewing a page without user authentications.

In my project, different user's have username and encrypted passwords. On
valid authentication user is allowed to go into the site. Here the problem
occours when the user is trying to view the files, whereas if user downloads
the file, its downloads properly with the correct file.

Thanks,
Baren
