exception thrown. Access violation reading Location

Question

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.

Answer 1

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.
