Peter,

What is in the code for play_animation? Are you looping through and repainting on every invocation of the loop? It seems like that is the case here.

What you really want to do is create a timer which you invalidate your picturebox on every tick (the frame rate of your animation will depend on the frequency of the timer).


Yes. I am looping through dozens of on-screen objects, updating their position. That's what my program does, and spends all its time. In the main animation loop, I still use a myBuffer.Render() command, as the drawBox.Invalidate() command flickers (even though it just does a myBuffer.Render() ).

I was told before (and I think by you) to use a timer in asynchronous thread. It didn't seem an issue in my app, as most people will want to run it flat out, so having two threads was more complexity that I didn't understand.

The annoying thing is that it is just a problem at start up of the Form. Everything else works brilliantly.

Is there some quick and dirty I can do for the start-up to make the form appear before the animation starts (or even finishes!)?

Or if I have to do this properly, can you refer me to a web page that might get me started?
