[英]How to create a full screen application in Win CE 6.0 using .NET Compact Framework 3.5?
我們希望我們的應用程序以全屏模式運行,在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指針都表示贊賞。
首先,您必須通過P / Invoke隱藏任務欄。 這是C代碼,應該很容易轉換 :
HWND hwndTaskbar = ::FindWindow(_T("HHTaskBar"), NULL);
::ShowWindow(hwndTaskbar, SW_HIDE);
完成后,使用Screen.PrimaryScreen確定顯示器的大小,並將表單調整為這些尺寸。
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;
}

return rect;
}
}
