You have the right idea. The proper way to exit an application is to find
it's main window handle and send it a WM_CLOSE message. You can also use
TerminateProcess, but that is an emergency measure only. It's basically like
using the "End Process" button of the Task Manager.

Finding a main window handle is not difficult. There have been several
different solutions posted through the years. Search the archive for
BodyContains = FindWindow and you'll get a lot of hits.

If the application is stubborn and doesn't want to close, search the archive
for AttachmentName = KillExcel. Excel is notorious for not behaving properly
:). KillExcel is easy to modify for any process.
