The Timer control works as a projector, retrieving frames from the bitmap, which is selected into memory device context. Obviuosly it takes a small fraction of time and does not degrade performance too much.
Though you must understand that the Timer is in the same process and thread as the whole FoxPro application. That means it can stop or slow down while there is another time consuming operation around.
