VB 6 Program Exe file

Sir:

I have a VB main program that includes a menu that calls/executes another vb exe file. Problem is, I want the other vb exe file to get the focus (if it is open) should the user attempts to set the focus on the main exe. I tried to trap it inseveral events of the MDI form (e.g. Activate, mousedown) but it failed to do what I want to happen. Are there any other techniques/tips you can give me?

Thanks in advance.
