EDIT: Tried doing: Code: private void Form1_KeyDown(object sender, KeyEventArgs e) { Graphics GE = Graphics.FromHwnd(this.Handle); Pen PE = new Pen(Color.Black); Rectangle NE = new Rectangle(15, 15, 20, 50); GE.DrawRectangle(PE, NE); if (e.KeyCode == Keys.Down) { NE.OffSet(17,17); } } To move the current shape drawn, but it doesn't move at all.

        private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            Graphics GE = Graphics.FromHwnd(this.Handle);
            Pen PE = new Pen(Color.Black);
[B]            int X = 10;
            int Y = 10;[/B]
            Rectangle NE = new Rectangle(15, 15, [B]X, Y[/B]);

            if (e.KeyCode == Keys.Down)
            {
                Y++;
                GE.DrawRectangle(PE, NE);
            }
        }
