WM_PAINT work on tabs and resetting to default colour

5 posts in this topic

i have some troubles with WM_PAINT work on tabs (it wont redraw pic on tab item change) and also with resetting image place holder to default colour before drawing new pic in to it (previous pic can be seen if it aspect ratio is different from new)...

what i'm doing wrong?
