As somebody else suggested, follow Petzold's example.  However, the
really crucial thing is this: when you register your Window's class,
don't give it an icon.  That way you ensure that all repaint requests
will come to you via the WM_PAINT message.  Then you can test your
window handle with IsIconic() to find out if you have to paint the 
icon or the window.  I use this for a Mac-style trashcan.  I just
use DrawIcon with the plain icon (for empty can) or a bulging icon
(for a can with something in it).  Easy.

The trick is to have no ICON, but descent the PAint method and look
at IsIconic(HWindow) and then do the painting.

Look at the OWLDEMOS/GDIDEMO how they do it.
