listbox鼠标拖动数据和为button注册快捷键

分别对应控件注册如下事件DragEnter，MouseDown，DragDrop

代码如下：

//P128 DataGridView的托动改成listBox的拖动
        private void listBox1_DragEnter(object sender, DragEventArgs e)
        {
            e.Effect = DragDropEffects.Move;
        }

        private void listBox2_DragEnter(object sender, DragEventArgs e)
        {
            e.Effect = DragDropEffects.Move;
        }

        private void listBox1_MouseDown(object sender, MouseEventArgs e)
        {
            listBox1.DoDragDrop(listBox1.Text, DragDropEffects.Move);
            //MessageBox.Show(listBox1.Text);
        }

        private void listBox2_DragDrop(object sender, DragEventArgs e)
        {
            //MessageBox.Show((string)e.Data.GetData(typeof(string)));
            listBox2.Items.Add((string)e.Data.GetData(typeof(string)));
        }

button注册快捷键方式：

//方法一
        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {
            if (keyData==(Keys.Control | Keys.R))
            {
                this.buttonX1.PerformClick();
                return true;
            }
            return base.ProcessCmdKey(ref msg, keyData);
        }
   　　 //方法二
        protected override bool ProcessDialogKey(Keys keyData)
        {
            if (keyData==(Keys.Control|Keys.Shift|Keys.R))
            {
                this.buttonX1.PerformClick();
                return true;
            }
            return base.ProcessDialogKey(keyData);
        }
        private void buttonX1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("被点击了！");
        }
