wince隐藏任务栏

前段时间做了一个wince项目。因为wince设备屏幕一般都比较小，所以经常隐藏任务栏来增大界面空间。在ce程序中调用下面的代码可以控制系统中任务栏的隐藏和显示

 

下面是代码：

/// <summary>
/// 调用winceAPI
/// </summary>
public abstract class CommonApi
{
    [DllImport("coredll.dll", EntryPoint = "FindWindow")]
    public static extern int FindWindow(string lpWindowName, string lpClassName);
    [DllImport("coredll.dll", EntryPoint = "ShowWindow")]
    public static extern bool ShowWindow(int hWnd, int nCmdShow);
    [DllImport("coredll.dll", EntryPoint = "SystemParametersInfo")]
    public static extern int SystemParametersInfo(
      int uAction,
      int uParam,
      ref Rectangle lpvParam,
      int fuWinIni
      );
    public const int SPI_SETWORKAREA = 47;
    public const int SPI_GETWORKAREA = 48;

    public const int SPIF_UPDATEINIFILE = 0x0001;
    public const int SPIF_SENDCHANGE = 0x0002;

    public const int SW_HIDE = 0;
    public const int SW_SHOWNORMAL = 1;
    public const int SW_SHOW = 5;
    public const int SW_SHOWNA = 8;
}

 

 

/// <summary>
/// 隐藏开始方法
/// </summary>
private static Rectangle winRectangle = new Rectangle();
public static bool SetFullScreen(bool fullscreen)
{
    int Hwnd = 0;
    Hwnd = CommonApi.FindWindow("HHTaskBar", null);
    if (Hwnd == 0) return false;
    if (fullscreen)
    {
        CommonApi.ShowWindow(Hwnd, CommonApi.SW_HIDE);
        Rectangle rectFull = Screen.PrimaryScreen.Bounds;
        CommonApi.SystemParametersInfo(CommonApi.SPI_GETWORKAREA, 0, ref winRectangle, CommonApi.SPIF_UPDATEINIFILE);//get
        CommonApi.SystemParametersInfo(CommonApi.SPI_SETWORKAREA, 0, ref rectFull, CommonApi.SPIF_UPDATEINIFILE);//set
    }
    else
    {
        CommonApi.ShowWindow(Hwnd, CommonApi.SW_SHOW);
        CommonApi.SystemParametersInfo(CommonApi.SPI_SETWORKAREA, 0, ref winRectangle, CommonApi.SPIF_UPDATEINIFILE);
    }
    return true;
}

 

调用方法

/// <summary>
/// 应用程序的主入口点。
/// </summary>
[MTAThread]
static void Main()
{   
    try
    {
        //隐藏开始
        SetFullScreen(true);
        //显示开始
        SetFullScreen(false);
    }
    catch (Exception ex)
    {
        Common.SetFullScreen(false);
    }
}
