I''m confused as to why a call to GetDC() would cause problems for your debugging session. Running graphics in exlusive mode would, but...

What compiler are you using?

If you are running in exclusive mode, I usually use PlaySound to find where I''m crashing (if it beeps before it fatals, I know that the crash is somewhere after that... makes it easy to narrow down the bug''s location.)

They say you can debug fullscreen exclusive apps with either two monitors or over an ipx network connection. Since I dont have any, I can only dream

Anyways, this is what I''m using for my project. I dont really understand exceptions, but when they happen the program doesnt just exit, it exits exclusive mode (DebugKillDDraw ()) and gives me the exception address. I throw the address in the exception wizard (http://members.aol.com/ExceptWiz/index.html) and voila : the exact place where the code crashed

And I can always put a breakpoint in that __except block and see my data.

I also use lots of asserts that on failure call DebugKillDDraw and then go into a breakpoint and let me look at the data.

Maybe you could use a similar approach with your DC problems, only instead of DebugKillDDraw, you might have a DebugReleaseBuggyDC function.

I can guess this is pretty obsolette stuff, but it helped me alot..
