using a new guid as a file name
Hi,
Users can upload images onto my site.
However I want to rename them and give them a random name.
I wanted to create a guid that would be used as the filename.
Something like:
Dim file As String = newFileName.ToString & "." & file_ext
but when i create the file with that the name is:
00000000-0000-0000-0000-00
any ideas?
