Problem


I am frequently updating the grid. The problem is that is starts flickering a lot. Is there a way to turn off the flickering?


Cause



Action


Yes, you can tell the grid to draw to a memory device context. This will be a bit slower than drawing direct to the device context, but will look much smoother. There will be absolutely no flickering anymore.

To enable this special mode, you should call

SetDrawingTechnique(gxDrawUsingMemDC);
