Parameter to center window on desktop

[Nobody/Anonymous]

Is there any parameter i can set at CreateWindow to make my MainWindow always show at the center of the Desktop?

The simple answer is no but it is quite easy to do. You can refer to the MSDN website to find info on functions.

I have a small routine which will centre a window on your screen:

   void CentreWnd()
   {
      RECT  rc2, rc1;
      RECT  FAR *lprc;
      int   nWidth, nHeight, cxCenter, cyCenter;
      HWND  hParentWnd;

      // Set the hParentWnd variable. If no window exists then the parent is the desktop.
      hParentWnd = GetParent();
      if (!hParentWnd)
         hParentWnd = ::GetDesktopWindow();
   
      ::GetWindowRect(hParentWnd, &rc2);
      lprc = (RECT*)&rc2;
 
      cxCenter = lprc->left+((lprc->right-lprc->left)/2);
      cyCenter = lprc->top+((lprc->bottom-lprc->top)/2);

      GetWindowRect(rc1);
      nWidth  = rc1.right-rc1.left; 
      nHeight = rc1.bottom-rc1.top;
   
      Move(cxCenter-(nWidth/2), cyCenter-(nHeight/2), nWidth, nHeight);
      return;   
   }

I have this function built into a class which manages all Win32 API calls which manage actions on windows.

Sorry - as this is it won't work as you need to modify the Move line to:

::MoveWindow(_hwnd, x, y, width, height, TRUE);

where _hwnd is the handle to the window you wish to centre.

note that in my class _hwnd is the member variable.
