[System.Runtime.InteropServices.DllImport("coredll.dll", EntryPoint = "FindWindow")]
        public static extern int FindWindow(string lpWindowName, string lpClassName);
        [System.Runtime.InteropServices.DllImport("coredll.dll", EntryPoint = "ShowWindow")]
        public static extern int ShowWindow(int hwnd, int nCmdShow);
        public const int SW_SHOW = ; //显示窗口常量
        public const int SW_HIDE = ; //隐藏窗口常量
        public static bool HideTaskBar(bool FLAG)
        {
            int Hwnd = FindWindow("HHTaskBar", null);
            if (Hwnd == ) return false;
            else
            {
                if (FLAG)
                {
                    ShowWindow(Hwnd, SW_HIDE);
                }
                else
                {
                    ShowWindow(Hwnd, SW_SHOW);
                }
