I have a program with SDI document and i'm drawing all kinds of things on the client area. What i did was to call Draw functions of all object that should be drawn from the View class Draw function.
My problem is that it draws everything slowly. What i tried was to create a temp CDC object and send it to the draw functions and when it returns copy it to the active DC. I tried using BitBlt but it doesnt work. How can i do this?
