Preventing multiple instances of a Windows app - still a problem

Since you just want to kill the process, and not necessarily bring it to
the front or anything like that, I think this is great advice. Just kill it
through shell, shouldn't matter if its actually running or not.

However, on the vbscript side I found a MUCH easier way to see if the
process is running.

Do the following as vbscript. (can run it direct, no need for a tmp file or
anything)

Set colProcessList = GetObject("Winmgmts:").ExecQuery ("Select * from
Win32_Process WHERE Name = 'System Idle Process'")
result = colProcessList.Count

If the result is > 0 the process is running. Note the single quotes around
my process name.
