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);    }}
