After running for almost half an hour my program throws an exception.

  1. dadc = GetDC();
  2. dadc->FillRgn();

It throws exception at line 2. How to handle it??

Regards.

    Maybe GedDC returned NULL due to insufficient resources, because you did not free or did not manage correctly some GDI objects.

    Check if dadc is valid and show more details.
