Quick system info retrieval
Kris McCann
Quite often it is necessary to retrieve certain information about the
system. I have seen all sorts of API calls to get snippets of
information such as the Windows directory, but a lot of people seem to
have missed the "environ" function. With this function you can return a
wealth of information from a single line of code - and it's fast.
Code: Environ("")
Returns a string, where can be any of the following:
ALLUSERSPROFILE
APPDATA
CommonProgramFiles
COMPUTERNAME
ComSpec
HOMEDRIVE
HOMEPATH
LOGONSERVER
NUMBER_OF_PROCESSORS
OS
Os2LibPath
Path
PATHEXT
PROCESSOR_ARCHITECTURE
PROCESSOR_IDENTIFIER
PROCESSOR_LEVEL
PROCESSOR_REVISION
ProgramFiles
SystemDrive
SystemRoot
TEMP
TMP
USERDOMAIN
USERNAME
USERPROFILE
windir
If you wish to dump all of the environment variables, this simple piece
of code will work:
For i = 1 To 26
Debug.Print Environ(i) & vbCrLf
Next i

Special Bonus Tip
Get quick access to your source code
Frank Silva
This is really more an organizational tip than a true VB tip, but it
has helped me greatly, especially in the field. By saving my code
snippets as Outlook Notes, I am able to download them to my Palm Pilot.
Therefore, anywhere I go, I can have access to my source code.
