Given two Win16 applications running on Windows 98:

One of the applications would like to close the other at shutdown time.  The
problem is that it doesn't have the task handle for the other app.  Win16 seems
to offer limited task management calls.

Would this technique work even in theory:

EnumWindows -- get all top-level windows in all running programs
GetWindowTask on the one I need
PostAppMessage (WM_QUIT) on the resulting task


I think if I can get the window of the remote app (it has only one), then from
there I can maneuver around.  The problem is what facility exists in Win16 to
get the handle to a remote app's main 
window.

Open to ideas here,

    That should work, but you shouldn't need to find the window's task handle. 
As you get passed each HWND in the system, you can pass it on to
GetWindowText() to check the caption. If it's the
window you are looking for, then call PostAppMessage(hWnd,WM_QUIT,0,0).  This
works if you know the window's caption (assuming it has one).  If you know the
window's class name, you could use
GetClassName() instead checking the caption.

        Hope this helps,

This was my solution:

other_window = FindWindow(NULL,"Other Window Title");
if (other_window != 0) PostMessage(other_window,WM_DESTROY,0,0);

Since I know the title of the external window these two lines of code always
work.
