How to create a full screen application in Win CE 6.0 using .NET Compact Framework 3.5?

We want our application to run in full screen mode with no title bar on a Win CE 6.0 powered de开发者_如何学编程vice. The application is being developed using .NET Compact Framework 3.5 (C#). Any sample code or pointers to articles is appreciated.

Use this code:

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)

First, you have to hide the task bar via P/Invoke. Here's the C code, which should be really easy to convert:

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

Once you do that, then use Screen.PrimaryScreen to determine how big your display is and resize your form to those dimensions.
