Enabling Double Buffering

Question

I\'ve seen the following code to enable double buffering on a winform:

// Activates double buffering 
this.SetStyle(ControlStyles.DoubleBuffer |
   ControlSt         


        

Answer 1

Control.DoubleBuffering performs

SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, value);

so your code sets ControlStyles.UserPaint as well (which probably has no effect at this point).
