If you're using BlitzMax, you can probably use its built-in AppSuspended() command to check whether the program is active or not.

When the system shuts down, there is a message broadcasted. The name of these messages can be found here:

In order to get these messages for your window, you should use either api_GetMessage (waits for message) or api_PeekMessage (doesn't wait)

The decls for these can be found here:

In this thread, you can find the numbers that belong to this messages:

The 'hwnd' of your window can be found with this:
print SystemProperty$("apphwnd")

You'll have to experiment to get this working. I'm not exactly sure how it should be done.
