RE: [Dev-C++] restoring window

[Vlada D. <dj...@im...>]

I'm having some problems with this, because the program "freezes" when I
use WM_PAINT. Is this message generated when dialog box pops up in front
of the window or when I draw line with the mouse? Is there some other
message that causes window to redraw its content?

Sorry.

Either perform all drawing to a bitmap that may be blitted back to the
window on a WM_PAINT, or keep a list of all draw operations, and replay
the list. The OS does not keep track of the contents of the windows.
