如何使用.NET Compact Framework 3.5在Win CE 6.0中創建全屏應用程序？

Question

我們希望我們的應用程序能夠在全屏模式下運行，並且Win CE 6.0驅動的設備上沒有標題欄。該應用程序正在使用.NET Compact Framework 3.5（C＃）開發。任何示例代碼或指向文章的讚賞。

Answer 1

首先，您必須通過P/Invoke隱藏任務欄。這裏的C代碼，這應該是很容易to convert：

HWND hwndTaskbar = ::FindWindow(_T("HHTaskBar"), NULL); 
::ShowWindow(hwndTaskbar, SW_HIDE); 

一旦你這樣做，然後使用Screen.PrimaryScreen以確定您的顯示器有多大和調整您的表格，這些尺寸。

使用此代碼：

public class FullScreenEngine 
{ 
    // Fields 
    private IntPtr _hWndInputPanel; 
    private IntPtr _hWndSipButton; 
    private IntPtr _hWndTaskBar; 
    private Rectangle _desktopArea; 

    public FullScreenEngine() 
    { 
     Init(); 
    } 

    public bool SetFullScreen(bool mode) 
    { 
     try 
     { 
      if (mode) 
      { 
       if (_hWndTaskBar.ToInt64() != 0L) 
       { 
        ShowWindow(_hWndTaskBar, SW_HIDE); 
       } 
       if (_hWndInputPanel.ToInt64() != 0L) 
       { 
        ShowWindow(_hWndInputPanel, SW_HIDE); 
       } 
       if (_hWndSipButton.ToInt64() != 0L) 
       { 
        ShowWindow(_hWndSipButton, SW_HIDE); 
       } 
       WorkArea.SetWorkArea(new RECT(Screen.PrimaryScreen.Bounds)); 
      } 
      else 
      { 
       if (_hWndTaskBar.ToInt64() != 0L) 
       { 
        ShowWindow(_hWndTaskBar, SW_SHOW); 
       } 
       if (_hWndInputPanel.ToInt64() != 0L) 
       { 
        //ShowWindow(_hWndInputPanel, SW_SHOW); 
       } 
       if (_hWndSipButton.ToInt64() != 0L) 
       { 
        ShowWindow(_hWndSipButton, SW_SHOW); 
       } 
       WorkArea.SetWorkArea(new RECT(_desktopArea)); 
      } 
     } 
     catch (Exception) 
     { 
      return false; 
     } 
     return true; 
    } 

    private bool Init() 
    { 
     try 
     { 
      _desktopArea = Screen.PrimaryScreen.WorkingArea; 
      _hWndInputPanel = FindWindowW("SipWndClass", null); 
      _hWndSipButton = FindWindowW("MS_SIPBUTTON", null); 
      _hWndTaskBar = FindWindowW("HHTaskBar", null); 
     } 
     catch (Exception) 
     { 
      return false; 
     } 
     return true; 
    } 

    private const uint SW_HIDE = 0; 
    private const uint SW_SHOW = 1; 

    [DllImport("coredll.dll")] 
    private static extern int ShowWindow(IntPtr hwnd, uint command); 

    [DllImport("coredll.dll")] 
    private static extern IntPtr FindWindowW(string lpClassName, string lpWindowName); 

    // Nested Types 
    public struct RECT 
    { 
     public int Left; 
     public int Top; 
     public int Right; 
     public int Bottom; 

     public RECT(Rectangle rect) : this() 
     { 
      Left = rect.Left; 
      Right = rect.Left+rect.Width; 
      Top = rect.Top; 
      Bottom = rect.Top + rect.Height; 
     } 
    } 

    private static class WorkArea 
    { 
     [DllImport("coredll.dll")] 
     private static extern bool SystemParametersInfo(uint uAction, uint uparam, ref RECT rect, uint fuWinIni); 

     private const uint WM_SETTINGCHANGE = 0x1a; 
     const uint SPI_GETWORKAREA = 48; 
     const uint SPI_SETWORKAREA = 47; 

     public static bool SetWorkArea(RECT rect) 
     { 
      return SystemParametersInfo(SPI_SETWORKAREA, 0, ref rect, WM_SETTINGCHANGE); 
     } 

     public static RECT GetWorkArea() 
     { 
      var rect = new RECT(); 
      SystemParametersInfo(SPI_GETWORKAREA, 0, ref rect, 0); 
      return rect; 
     } 
    }
