Simple questions: Placing Pixels on a form

Hello,
I'm trying to fill a windows form with red pixels.

My code is included bellow. I tried to place it in mouse down event handlers, paint event handlers but the result is mostly the same : the application slows down ( almost crashes) and does not display the pixels.


{

Bitmap bmp = new Bitmap(this.Width, this.Height);

for (int i = 0; i < this.Width; i++)

for (int j = 0; j < this.Height; j++)

bmp.SetPixel(i, j, Color.Blue);

Graphics g = this.CreateGraphics();

g.DrawImage(bmp, new Point(0, 0));
