    UpdateData???

    Everything works as expected in release mode...In debug mode there is an assertion failure in wincore.cpp line 884. If I hit ignore the code proceeds through the loop and the text is actually updated, but next time it hits the UpdateData(false) line there's the same assert error. It's strange...

    MS VC++ 6.0 application question

    I'm trying to copy a dialog from one project to another, so I don't have to lay it out again. Is there anyway to do this? I've exported other resources (ie bitmaps), but I can't figure out how to transfer the dialogs. Thanks.
