     **DOUBLE BUFFERING FOR BEGINNERS** Drawing constantly to a picture box causes huge amounts of flickering which is undesirable and looks unprofessional. This is a very easy way of removing the flickers using the double buffer method. Double Buffering has been used in games since time began, even back on the Amiga with Blitz Basic and Amos. The idea is to draw all details into a buffer, this means the user cannot see it and it is very quick. Once all the drawing is complete it is then copied to the front buffer (Picture box in this case). This means there is only ever one update per cycle as opposed to an update for every item drawn. When I began looking for this I found only examples of drawing onto a form... well that's a cheat, it has a DoubleBuffer property, a picture box doesn't... I'm not fussed about votes folks, just let me know if this has helped.
