Hi,

One approach is to intercept WM_ENTERSIZEMOVE and WM_EXITSIZEMOVE messages
to detect the start and end of the resizing operation and set a flag during
the move to stop painting until the drag finishes.

Best way is to remove CS_VREDRAW and CS_HREDRAW in the class style. Also,
calculating the new area to be drawn and only drawing there (if you don't
need to redraw the old area) will help a ton.

Yes, I argee with that, remove CS_VREDRAW and CS_HREDRAW. The list of
rectangles to re-draw can be gotten from ::GetUpdateRgn and then
::GetRegionData. Clip your datastructure according to this list.
