Determine Parent of Script

[tyrant1969]

I have a VBscript that performs several steps for me but it can be called by one of a few different processes.

Most of the steps are identical for both processes - if process 1 calls the VBS file it does steps 1,2,3,4,5,6; but if process 2 calls the VBS file I want it to do 1,2,3,7,8,9 and if process 3 calls it I want it to do 1,3,4,7,9,10 and 11.

How do I tell what external program called my script?

The easiest way would be for the external programs to call it with an argument that identifies the program that called it.

That would be ideal, but two of the three processes that call it right now we didn't create.

Any other thoughts?

In that case you may be able to navigate through the WMI Win32_Process class to use the .ParentProcess property to figure it out.

Man...you're everywhere! LOL Thanks, I'll give that a shot.

Using your suggestion of the ParentProcess property, along with the fact that I know that this is a unique process when it is called I was able to get my app's PID, determine the parent PID and look up the name of the parent.

Then, dependent on what the name of the parent was I executed the appropriate sub-set of the scripts.

Thanks!
