C# :: Mouse View In Picturbox?

i would like to add a image box to my application which shows a view/picture where ever my mouse is pointing. something like windows magnifier but it must not zoom in anything it must just display in picture box what your pointer is on.

So basically you have a picture box 504, 86 okay in a form when you move your cursor of mouse around desktop what ever you look at it will be visible inside picture box.

This is what i have so far.

private void MainForm_Load(object sender, EventArgs e) {
objPct.Visible = false;
this.Controls.Add(objPct);
}
PictureBox objPct = new PictureBox();

[code].....
