Rendering controls on glass: Solution found, needs double-buffering/perfecting

Question

I (finally!) found a way of rendering Windows.Forms controls on glass that doesn\'t seem to have any major drawback nor any big implementation time. It\'s inspired by this artic

I had a problem with flickering before (lots of controls on the form, user controls). Tried almost everything. This is what worked for me:

Have you tried putting this in your form class?

    protected override CreateParams CreateParams
    {
        get
        {
            CreateParams cp = base.CreateParams;
            cp.ExStyle |= 0x02000000; // WS_EX_COMPOSITED
            cp.ExStyle |= 0x00080000; // WS_EX_LAYERED
            return cp;
        }
    }

And in your constructor you have to enable double buffering, otherwise it won't work:

this.DoubleBuffered = true;
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);

It only works when aero is enabled, if not it can make flickering even worse.

and you can also add this

  protected override CreateParams CreateParams
    {
        get
        {
            CreateParams cp = base.CreateParams;

                cp.ExStyle |= 0x02000000; // WS_EX_COMPOSITED
            return cp;
        }
    } 

to your UserControls class.
