Flickering while refreshing

[Jack Smash]

Hi,

I'm using a UserControl object for all the graphics handling in my
application. However, if I select an image and move it around, I get
flickering. So in order to get rid of the flickering, I added this code in
the constructor of the UserControl:

this.SetStyle(ControlStyles.AllPaintingInWmPaint |
ControlStyles.DoubleBuffer, true);

Now the control doesn't flicker, but I still get some minor flickering of
the image I am moving, and if I move the mouse too quickly, the image will
not "keep up" with the mouse pointer.

Any suggestions?

how exactly are you moving that image around? If you are doing all
your painting to the Graphics object that comes through onpaint then
if your using doublebuffer and all painitng in paint you shouldn't get
any flicker at all. Are you instead using a second control and
painting on that perhaps?

Also, are you overriding OnPaintBackground?
