My first question is...why not declare the window without the
WS_THICKFRAME parameter.  Else, if you really want to get down
and dirty...

WM_SYSCOMMAND, SC_MOVE | SC_SIZE

These messages are sent just before the window is about to be movedor
sized.  You can do all sorts or nasty things here, like returning
with some valid return value (see samples/defprocs/defwnd.c for more
info on how windows processes the message).  I myself would disable
the thickframe style, and avoid messyness.

I would think your application would know better how to manage the client
updating better than windows.  i.e. keep a bitmap around for yourself, and
make it discardable, so in low memory situations, the bitmap will
disappear, but you could re-create it in such a case.  This is basically
what windows does with the CS_SAVEBITS...notice the mention that it MAY
NOT ALWAYS SAVE the BITS in low memory situations.
