Drawing Graphics and undo this

Markus

Hi,

if got the following Problem. I want to draw an Rectangle on an loaded Image
when the Right Mouse Button is Pressed and the Rectangle should Resize, when
the MouseMove Event is fired. So my Problem is, that i cant find a Method,
where i can undo the Paint of the Rectangle and do a new Paint and that
without flickering.

Excuse my Bad English.

Regards
Markus

Lots of help for you exists in the GDI+ FAQ and Windows Forms Tips and
Tricks.

You've asked about half a dozen questions there really.

Look for double buffering, drawing on images, why stuff disappears and
so-on.
