Full screen MFC application

Hi everybody,

I'm developping an application with MFC (VC 6.0), and I'd like that the main modal of my application to be in full screen, and I'd like that it works for different screen size.
For the moment I use the  following code:

// Put window on top and expand it to fill screen
      int cx, cy;
    HDC dc = ::GetDC(NULL);
      cx = GetDeviceCaps(dc,HORZRES) +
        GetSystemMetrics(SM_CXBORDER);
    cy = GetDeviceCaps(dc,VERTRES) +
        GetSystemMetrics(SM_CYBORDER);
    ::ReleaseDC(0,dc);

    ::SetWindowPos(m_hWnd, HWND_TOPMOST,
        -(GetSystemMetrics(SM_CXBORDER)+1),
        -(GetSystemMetrics(SM_CYBORDER)+1),
        cx+1,cy+1, SWP_NOZORDER);

But it just expand the window....
Moreover I'd like that this main window (the window which appears when you launch the program) to be not moved by clicking on the menu bar and moving the mouse...  
Hope you see what I mean.
Thanky by advance.
Vincent.

Do you mean maximised?
If so in the InitInstance
m_pMainWnd->ShowWindow(SW_MAXIMIZED);

In the InitInstance of MyApp.cpp, I have put:

m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);

like this
                ...
                int nResponse = dlg.DoModal();
      m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);
                ...

and the window is not maximised and I've an error after I close the application...
Could you tell me what I've done wrong?
Thanks

In that case you need the ShowWindow(SW_MAXIMIZED) in the OnInitDialog (after the CDialog::OnInitDialog()) of the dialog and remove the line
m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);

Thanks, now it works. I'd like to know if there is a way to center the window in the screen. For the moment my window is in the left-top corner, and i'd like to change the distance between the items of my window to fit with different screen sizes... A kind of scale change if you see what I mean...
I'd like that a button on the right down corner of my window to be at the right down corner of the screen, even if the user screen is bigger than the original size of my dialog...

Trap the OnSize message (that has the params for the new size).
GetDlgItem(IDC_XXX)->SetWindowPos(NULL, left, top, 0,0, SWP_NOZORDER|SWP_NOSIZE);
will just move a control.

GetWindowRect, GetClientRect and ScreenToClient, ClientToScreen are other functions to look up in help.

To center the window on the desktop. Within your OnInitDialog message handler, insert this line:

CenterWindow(CWnd::GetDesktopWindow());

Andy is correct... you will need to write special (custom) code to move and resize the controls... MFC does not provide that capability.  

If there are just a few controls, you can just move and resize them "manually" one-at-a-time in the OnSize handler.  If you have *lots* of controls, you may want to use a scheme where you keep track of the positions and sizes of each control in an array, and then cycle through the array moving and resizing them in turn.

By the way, I always caustion programmers against forcing their window to cover the entire screen.  There are *very* few cases where this is advisable, but novice programmers tend to always want to do it.  Sure, your program is very important... to YOU... but your user may have several other programs, web browsers, etc. open and those other programs may be very important ... to HIM :-)
