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

using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

[DllImport("coredll.dll", EntryPoint = "EnableWindow")]
public static extern bool EnableWindow(IntPtr hwnd, bool bEnable);

if (!hwnd.Equals(IntPtr.Zero))
{
if (enabled)
{

}
else
