Winform Application flickers on XP system

Hi I have a windows application (winform .net framework 4). The app is flickering alot on windows XP system. I added code:

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

The flickers were removed when I added above code. It worked fine on my development system which is windows 7 32 bit but On Windows XP the flickers has increased and also the background image is not loaded.

Is there any way by which flickers can be removed in all the windows OS?

Here is some information about Double Buffering. This is a built-in feature that is turned off by default. In my experience it doesn't always help but it is worth trying.

To turn it on, open the designer and select the form and look in the Properties of the form. Under the category 'Behavior' you will find the DoubleBuffered property. Just set this to true.

You may also try 

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