Offhand the only way I know would be to enumerate the running
processes with...
CreateToolhelp32Snapshot
Process32First
Process32Next
...until you find one with the correct exename. Stash the process ID
from that, then enumerate the top-level windows with EnumWindows until
you get one who's PID matches.
Of course if your app is launching the exe, VB's shell or several Api
methods can provide the PID at that time, and you could skip the
process enumeration part.
