Find my own process ID in VBScript

Question

I\'m using the following code snippet to determine what process ID my vbscript is running as:

On Error Resume Next
Dim iMyPID : iMyPID = GetObject(\"winmgmts         


        

Answer 1

Here's an even better code snippet:

      ' ***********************************************************************************************************
      ' lng_MyProcessID finds and returns my own process ID. This is excruciatingly difficult in VBScript. The
      ' method used here forks "cmd /c pause" with .Exec, and then uses the returned .Exec object's .ProcessID 
      ' attribute to feed into WMI to get that process's Win32_Process descriptor object, and then uses THAT
      ' WMI Win32_Process descriptor object's .ParentProcessId attribute, which will be OUR Process ID, and finally
      ' we terminate the waiting cmd process. Execing cmd is what causes the brief cmd window to flash at start up,
      ' and I can' figure out out how to hide that window.

      ' returns: My own Process ID as a long int; zero if we can't get it.
      ' ************************************************************************************************************

      Function lng_MyProcessID ()

        lng_MyProcessID = 0                     ' Initially assume failure

        If objWMIService Is Nothing Then Exit Function      ' Should only happen if in Guest or other super-limited account

        Set objChildProcess = objWshShell.Exec ( """%ComSpec%"" /C pause" ) ' Fork a child process that just waits until its killed

        Set colPIDs= objWMIService.ExecQuery ( "Select * From Win32_Process Where ProcessId=" & objChildProcess.ProcessID,, 0 )

        For Each objPID In colPIDs                  ' There's exactly 1 item, but .ItemIndex(0) doesn't work in XP

          lng_MyProcessID = objPID.ParentProcessId          ' Return child's parent Process ID, which is MY process ID!

        Next

        Call objChildProcess.Terminate()                ' Terminate our temp child

      End Function ' lng_MyProcessID
