Well, OnPaint() calls OnDraw(). I think OnDraw() is specific to views, whereas OnPaint() is for repainting in general. Five birds are sitting on a fence. Three of them decide to fly off. How many are left?

1. Yes 2. If I remember correctly (haven't done painting stuff for a while) the CPaintDC class prepares the window dc for painting (calling BeginPaint on creation and calls EndPaint when destroyed). So, I guess you should skip the GetDC and ReleaseDC calls alltogether and only use the CPaintDC (which, if I remember correctly has a HDC operator).

There is a lot of stuff in there to help you. http://pws.prserv.net/mfcogl/ Mykel Everything's beautiful if you look at it long enough...

I don't know what you mean by '#define new..." I'm overriding the MFCApp::ExitInstance() function and calling the base ExitInstance(). Then I do the object dump, so I can't see why a few objects are still allocated. BTW I am extremely paranoid about memory leaks after having lots of trouble with my last PC (crashing.......sloooowdown etc..)
