?I would like a VBS or other program that I can call that will give me the complete PATH and FILE name of the CALLING program?

Not sure if you can do that direct . . . but a work around would be to force your script to have a parameter that accepts the path & program name.  If it's not there error out of your script.

I have a script that will work using AutoIT, on one condition;

Within MYprog.exe, are you able to call this script with a switch that is MYprog.exe? For example, the script below (which we'll call ReturnsCallersLocation.exe) would need to be run like this:

ReturnsCallersLocation.exe MYprog.exe

_ProcessGetLocation($CmdLineRaw)

Func _ProcessGetLocation($iPIDa)
    $iPID=ProcessExists($iPIDa)
	Local $aProc = DllCall('kernel32.dll', 'hwnd', 'OpenProcess', 'int', BitOR(0x0400, 0x0010), 'int', 0, 'int', $iPID)
    If $aProc[0] = 0 Then Return SetError(1, 0, '')
    Local $vStruct = DllStructCreate('int[1024]')
    DllCall('psapi.dll', 'int', 'EnumProcessModules', 'hwnd', $aProc[0], 'ptr', DllStructGetPtr($vStruct), 'int', DllStructGetSize($vStruct), 'int_ptr', 0)
    Local $aReturn = DllCall('psapi.dll', 'int', 'GetModuleFileNameEx', 'hwnd', $aProc[0], 'int', DllStructGetData($vStruct, 1), 'str', '', 'int', 2048)
    If StringLen($aReturn[3]) = 0 Then Return SetError(2, 0, '')
    Return $aReturn[3]
EndFunc

Is this to troubleshoot a program to make sure the correct one is the one running? Or that it is running the correct script?

As I read your question, you are asking an external application to determine something for you that is available in the application itself.
 Every dos/windows programming language I have used has a function in it to determine the path of the program itself. ie If you are creating a myprog.exe there are calls from whatever programing language you are using to determine what you ask.

If you are trying to determine in the script if the correct program has called it then TheGorby's solution would work, but if you are trying to determine for myprog.exe where it is running from there are far simpler ways available to run inside the myprog.exe itself.

I am using an automation tool that does NOT have a user interface provitding the ability to compute it's own location.

thus, I would like to have a program that I can call that will determine the location of the calling program.



I am not sure what auto.IT is

I don't know how I would instantiate the switch equal to the calling program.
