I'm writing an app which has a couple of non-MDI child windows.  I can't find
an example of this anywhere in the SDK (*every* reference to "child" in
the Guide to Programming is for MDI!).

Anyway, my problem is this: I do not (of course) process all messages
in the child window's window function, and I just pass most of them on
to DefWindowProc().  Now, it seems to me that I should pass
DefWindowProc() the handle to the *child* window.  However, if I try
to do that, then CreateWindow() returns NULL!  I have to pass the
handle to the *parent* window, and then things seem to more-or-less work.

Now, this sounds really wrong to me.  Am I doing something wrong?  I'm
creating the window with WS_CHILD | WS_VISIBLE, and correctly specifying
the parent.  Right now I'm just processing WM_PAINT, although I'll be
processing other messages later.

Any insights would be very much appreciated.
