Timer

and it does not necessarily change it's x coordinate by a constant value. It may also changes its y value.

So?? The concept is still the same. You're just chaning the math that you have to do inside the Tick event.

Intresting, but I'd be delighted if you could give me some more detailed code because I am a real noob in C#. Thank you:)

And as such, I would be doing you a disservice if I provided you with code; read the documentation and experiment, you'll learn more.

I would definitely use a Windows.Forms.Timer since that one ticks on the GUI thread, hence the tick handler can manipulate all Controls directly without needing any Invoke stuff. :)

Yeah, but since he's so new at this, I didn't want to throw the control cross-threading problem into his already existant confusion.

I lost you guys... But I'll try to find some book about it. Thanks anyway:)

[Luc Pattyn]

Yep. use a Windows.Forms.Timer, but before you do read up on everything you plan on using. A book is always a good start. :)

If you just want an interval, System.Threading.Thread.Sleep() should do the job.

Yeah, but the change in location requires a WM_PAINT message to go through the pump, which youre suggestion just halted for x milliseconds, preventing the message from being processed and the form being repainted.

Didn't know that. Maybe you have a command for refreshing the form?

Regards, Leonardo Muzzi

[Dave Kreskowiak]

Yeah, it's Invalidate, which generates a new WM_PAINT event for the entire form. Same problem. If the UI thread is blocked (sleep), the form doesn't get painted.
