>In a vfp-function that calls an API function, a constant is declared. See my actual example:

I wanted to know the other possible values, so I searched for the text DRIVE_REMOTE on the internet and in my own header files.

Peter,
Visual Studio 6.0 includes API text viewer utility:
"The utility for viewing Win32 API Constants, Declares, and Types. Selected items can be copied from the API Viewer to Visual Basic applications or the Windows Clipboard."
