To jest cały program

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Jeden
{
		public partial class Form1 : Form
		{
				public Form1()
				{
						InitializeComponent();
				}

				private void Form1_Load(object sender, EventArgs e)
				{
						this.ActiveControl = this.panel1;
						this.panel1.KeyDown += new KeyEventHandler(panel1_KeyDown);
				}

				void panel1_KeyDown(object sender, KeyEventArgs e)
				{
						String s = e.KeyCode.ToString();
						e.Handled = true;
						MessageBox.Show(s);
				}
		}
}


Na Form1 jest Panel i to wszystko. Chciałbym na panellu rysowac
figurę, a badać klawisz Delete po to aby
można narysowaną fiigurę usunąć. Stąd takie proste ćwiczenie, ale nie
rrozumieem dlaczego MessageBoox.Show
wywwołuje mmi się dwa razy. e.Handled = true nie pomaga.

Pozdrawiam
