Load And Draw Bitmap

Hey im trying to load a draw a bitmap. But I don't know how to get the System.Windows.Form.PaintEventArgs?

Code:

---

private void Draw_Ball()
{
        Image ball = new Bitmap("c:\\source\\c#\\bounce\\ball.bmp");
        Graphics g = e.Graphics;
        g.DrawImage( ball, new RectangleF(10, 10,
        ball.Width, ball.Height) );
}

---

Anyone know what im doing wrong?

Thanks

Adapt your existing function to take a graphics parameter and then call your function from the Paint() event, passing e.graphics() into it via the new parameter.
