CreateFile() and fopen issues on vista

["Kirk Russell" <Krussell at bju dot edu>]

Hi,

I am trying to port a program from Windows XP to Vista and am running into several issues. 

1) When I issue an fopen of a file with "rb" or "wb" modes they fails. I have since switched to just a "r" and "w" and it now works. This was not an issue on XP.

2) When I issue a CreateFile() function call against f: which is a USB drive an invalid handle error is returned. I would appreciate any help solving this. Some of the things that I have done are.

             a) Ran as the admin user
             b) created a manifest file to run the process as admin
             c) Ran CreateFile() on a directory (f://test) and not the root for the USB drive (f:)
             d) Turned off UAC
