如何使用.NET Compact Framework 3.5在Win CE 6.0中创建全屏应用程序？

我们希望我们的应用程序以全屏模式运行，在Win CE 6.0驱动的设备上没有标题栏。 该应用程序正在使用.NET Compact Framework 3.5（C＃）开发。 任何示例代码或指向文章的指针都表示赞赏。

Answer 1

首先，您必须通过P / Invoke隐藏任务栏。 这是C代码，应该很容易转换 ：

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

完成后，使用Screen.PrimaryScreen确定显示器的大小，并将表单调整为这些尺寸。

使用此代码：

 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; } } }
