        public static extern int FindWindow(string IpClassName, string IpWindowName);
        [DllImport("user32.dll")]           //控制窗口的可见性
        public static extern int ShowWindow(int hwnd, int nCmdShow);
        [DllImport("user32.dll")]           //在窗口列表中寻找与指定条件相符的第一个子窗口
        public static extern int FindWindowEx(int hWnd1,int hWnd2,string Ipsz1,string Ipsz2);
        private void button1_Click(object sender, EventArgs e)
        {
            if (radioButton1.Checked)
                ShowWindow(FindWindowEx(FindWindow("Shell_TrayWnd", null), 0, "Start", null), SW_HIDE); //隐藏开始按钮  
            else
                ShowWindow(FindWindowEx(FindWindow("Shell_TrayWnd", null), 0, "Start", null), SW_SHOW);//显示开始按钮
        }
