Mapped Drives and Run As Administrator issue - Stuart McLachlan - 01-29-2025
Just ran into a little oops.
Writing a small backup utility to copy files from a mapped drive to a USB Thumb Drive.
I initially couldn't work out why it was silently failing with "Compile and Execute"
I tried running the executable from Windows Explorer and it worked.
Then it dawned on me
: I have PBEdit and PBWin set to "run as Administrator' to avoid the known issues with occasional slow compilation and/or compiler fails.
"Administrator " didn't have the drive mapping.
My solution:
Code:
dwDrives = GetLogicalDrives
IF BIT(dwDrives,25) = 0 THEN ' Drive Z not available
? "Cannot access source drive Z:\." & $LF & $LF & "You must run this application as a user with drive Z:\ mapped!" & $LF & $LF & _
"Note that the backup will fail if you run ""as administrator"" rather than as a normal user who has Z:\ mapped",%MB_ICONERROR,"Backup To USB Failed"
EXIT FUNCTION

Stuart, I think this MS article fixes the problem of a network share in one context (elevated/normal) not appearing in the other context.

Yes, it does in certain situations, but those solutions are not applicable in the use case of the utility I was developing (for users on workstations in a network I have no control over).
