Some questions

[Reinhard Pagitsch]

Hello everybody,

First I have to say I am new on wxwidgets. I use version 2.8.3.
If there is a better group for my questions please tell me or make a 
follow up.

Ok, now to my questions:
I am currently working on a little ball game. With the mouse I move the 
"hitter" and with a timer I move the ball around the frame.
I read that I have to use wxPaintDC in the OnPaint event and outside the 
wxClientDC.

I tried to move the ball outside of the OnPaint function but there I 
have the problem that the ball have traces. Now I put the paint of the 
ball also into the OnPaint function and it seems that it works, but only 
it seems. If I comment the function out which clear the previous painted 
ball there is also no trace of the ball.

But now I got an error message: "DAMAGE: after normal block (#1288) at 
0x00F8D998"
This message occurs if I exit the application.

Can anyone tell me how the best way to display an image which will be 
moved around the frame with a timer and what the problem with this error 
message is? Maybe someone have some code samples about it?

Thank you,
Reinhard
