// This method will adjust the size of the form to utilize 
// the working area of the screen.
private void Button1_Click(System.Object sender, System.EventArgs e)
	// Retrieve the working rectangle from the Screen class
	// using the PrimaryScreen and the WorkingArea properties.
	System.Drawing.Rectangle workingRectangle = 

	// Set the size of the form slightly less than size of 
	// working rectangle.
	this.Size = new System.Drawing.Size(
		workingRectangle.Width-10, workingRectangle.Height-10);

	// Set the location so the entire form is visible.
	this.Location = new System.Drawing.Point(5, 5);
