  1. Hi there. I would like to optimize the double buffer rendering system I made in win32 c++ programming with gdi+. So far I created an offscreen static bitmap surface and a global Graphics object to draw onto it. The problem is, every time I want to update the HDC of my window i need to create a new Graphic object and destroy it at the end of the event, like this: ... case WM_PAINT: hdc = BeginPaint(hWnd,&ps); graphics = Graphics(hdc); graphics.DrawImage(backbuffer,0,0,width,height); EndPaint(hWnd,&ps); break; ... //graphics gets destroyed at the end of WndProc   Since this operation is repeated almost 40 times per second, i was wondering wether creating and destroying every time that object would somehow slow down my program. Maybe this solution would be better: - using a new compatible HDC as the backbuffer instead of the BMP - inside WM_PAINT, copy that with BitBlt instead of creating a Graphics object What do you think?
