Pointers for solving windows GUI problem.

Greetings all,

I'm posting this question in the hope that someone has already done
this, or something similar, and can perhaps direct me some code or a
tutorial that will shorten the path to a solution.

I have a Windows COM object which renders a series of images into a
window. I can control the COM object using provided API methods. I
don't have the source for the COM object.

I want to do screen grabs of the display of this window at various
stages, so that I can dump them to files, in GIF, JPEG or PNG format.

What I'm looking for is perhaps some sample code that does this or
something similar. Failing that, a pointer to a good MFC tutorial
would be most helpful.

I am totally unfamiliar with MFC and Win32 GUI programming, although
I've developed some X-Windows stuff in the distant past.

However, given the excellent tools available, namely Python and Mark
Hammond's excellent Windows extensions, I have every faith that the
job can be done without having to go near VC++ (which I can do, but
really don't want to :-)

TIA for any pointers.
