Redraw the full screen?

How can I redraw the full screen (all the windows)?

i guees you are talking of invalidate,or then go for GetDesktopWindow()(desktop handle) then invalidate that,i havent done its just a guess ,if you mean one from program then just invalidate().

Thanks for the response. Unfortunately it didn't work :(( The reason I need to erase/redraw/invalidate everything is becouse I am drawing on the screen DC (GetDC(NULL)) but at the some point I want to revert changes. I guess enumerating all windows and invalidating the visible ones could work but I tought the might be a better way...

InvalidateRect(NULL, NULL, TRUE) will invalidate all windows. Now I need something like UpdateWindow or RedrawWindow, but for all windows. -- modified at 13:22 Saturday 1st October, 2005

Enumerate all the windows and if the WS_VISIBLE style bit is 1, then set it to zero then back to 1 and this toggle will force a repaint. Send an F5 keystroke to the desktop window and it will redraw all the icons etc. OR since you want to use the entire screen, create a window with no frame or menu and size it to the display then get the DC for that window. When that window is closed/destroyed all the other windows/desktop will redraw on their own. This is how many screen savers work!

Thank you. I think one of your methods will be perfect...
