Hey Guys
I have a shell extension and it generally works fine in release mode but when i compile it into debug mode i get assertion errors generally just before a MFC window is called.
Can someone tell me what causes these assertion errors and whether i should worry about them.
Cheers

MFC uses the ASSERT macro that does exactly the same. An assertion error is always a bad thing, and you should make sure you don't have any. If you ignore assertion errors, then you may get some weird errors in totally unrelated places that are hard to track.
Click "retry" when the assertion message comes, then "debug" in the next dialog. You will be placed at the line where the assertion failed. Using the call stack, you can then find out which function of yours called the function that asserted. You shold then set a breakpoint there and find out where the error comes from.
