Using BitBlt() Function !!
Posted on 2002-04-20
Hello Experts !!
I developed an SDI application which displays a Bitmap !! I call UpdateAllViews(NULL) very frequently when a MOUSE_MOVE message is sent. The problem is that the bitmap flickers a lot. I wanna reduce or simple avoid flickering, which is why I'm using BitBlt() function. but still It seems to flicker.
This is the code I've written;
dc.BitBlt(0,0,rc.Width(), rc.Height(), &memDC,0,0,BLACKNESS);
Can somebody tell me why this does not work as expected.
