Hi Glenn,
Sorry, I have NO knowledge of Win NT. I have searched Delphi 5's help
and could not find 'GetEnvironmentVariable' but I did find it under the
SDK info - but I don't understand it at all! I also searched for
'Userprofile' and didn't find that either. Are these now functions in
Delphi 8 or Turbo Delphi (which I can't run since they require Win XP
and I'm still running Win 98)?
