    ' using the PrimaryScreen and the WorkingArea properties. 
    Dim workingRectangle As System.Drawing.Rectangle = _
        Screen.PrimaryScreen.WorkingArea

    ' Set the size of the form slightly less than size of 
    ' working rectangle.
    Me.Size = New System.Drawing.Size(workingRectangle.Width - 10, _
        workingRectangle.Height - 10)

    ' Set the location so the entire form is visible.
    Me.Location = New System.Drawing.Point(5, 5)

End Sub
C#
    // 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 = 
            Screen.PrimaryScreen.WorkingArea;
        
        // 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);
