Hi! I can't get the CS_SAVEBITS option to work properly. Could somebody please give me a hint of what to do? I have created a standard frame window with my own window procedure to the client window. In the WM_CREATE part of that procedure I register a new window class with the CS_SAVEBITS option. I also create a small window of that class with my client window as parent and owner. This window is moved in the client window (trigged by a timer) with the procedure WinSetWindowPos ( ..., SWP_MOVE). All this works fine _BUT_ I also recieves WM_PAINT messages to my client window procedure every time my small window is moved! Why? And how can I avoid this. When I read my PM manual it says that CS_SAVEBITS (which implikates WS_SAVEBITS) should prevent this. Regards. | Per Ersson ! Hagelv. 1 rum 78 | E-adr: d89-pen@sm.luth.se | | University of Luleaa !
