c# wince 显示隐藏任务栏

[DllImport("coredll.dll", EntryPoint = "FindWindow")]
public static extern int FindWindow( string lpWindowName, string lpClassName );
[DllImport("coredll.dll", EntryPoint = "ShowWindow")]
public static extern int ShowWindow( int hwnd, int nCmdShow );
public const int SW_SHOW = 5; //显示窗口常量
public const int SW_HIDE = 0; //隐藏窗口常量

隐藏/显示Windows 任务栏的小例子：
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
int Hwnd = FindWindow("HHTaskBar", null);
if (Hwnd != 0)
{
ShowWindow(Hwnd, SW_HIDE); //隐藏任务栏
}
}

private void button2_Click(object sender, EventArgs e)
{
int Hwnd = FindWindow("HHTaskBar", null);
if (Hwnd != 0)
{
ShowWindow(Hwnd, SW_SHOW); //显示任务栏
}
}

//禁用开始菜单和键盘输入菜单
