[.net] Flickerless GDI+

1: it's probably purely api-specific question. I'll answer non-api specific part: the answer is "doublebuffering" (and google).

Just patiently wait while it will be moved to .net - relared forums.(don't crosspost!)(if you want you can report your post to moderator)

Like this in the OnPaint:

Bitmap b = new Bitmap(this.Width, this.Height, e.Graphics);
Graphics g = Graphics.FromImage(b);

g.Draw...
g.Draw...

e.Graphics.DrawImageUnscaled(b, 0, 0);
b.Dispose();
g.Dispose();

Cheers
