emoreau, WSH is out as a solution. Thanks.

Michael, this process is already running so the second part of the suggested answer won't work and the first part doesn't seem to. Even though the process stopped process or was hidden, the event never fired.

A couple of questions.

The 'proc' in "WaitForSingleObject(proc.hProcess, INFINITE)" is a HWND? to the process that was started with the shell application is that correct? So they are getting the HWND using 'SHELL', the process that I am using is already running so do I need to identify the HWND and PID of it and then supply it to the 'WaitForSingleObject' function ?

Karl Peterson's site has a sample with three solutions to shell and wait.

Click "Samples" from the menu and then scroll down to the item listed as Shell32.zip

This process has not been 'shelled' but is currently a running process. So, essentially I want to be able to wait for a process to end given a HWND and or PID.

Thanks,
