Question

I have developed a windows form application using c#. And now when I move the that form on desktop a very large trail appears. Its like when we move any window like notepad when system is overloaded. But when system is working fine. no overload still the trail appears. which doesn’t look good.
so is there any way to avoid that.
My system RAM is 2GB!

Answer 1

Do you use large pictures on winform?

You can try this:
Try to set the Double buffered property of the form.

or

Maybe you can solve with this code:

protected override CreateParams CreateParams {
get {
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x02000000;  // Turn on WS_EX_COMPOSITED
return cp;
  }
}

And finally you can try to set this property of the form : Transparency key with a color which you don’t use on your form.
