  Parameter      Description
 
  <dwExStyle>    Specifies the extended style of the CWnd being created.
                 It may be one of the following values:
 
                 Style                  Meaning
 
                 WS_EX_DLGMODALFRAME    Designates a window with a double
                                        border that may optionally be
                                        created with a title bar by
                                        specifying the WS_CAPTION style
                                        flag in <dwStyle>.
 
                 WS_EX_NOPARENTNOTIFY   Specifies that a child window
                                        created with this style will not
                                        send the WM_PARENTNOTIFY message
                                        to its parent window when the
                                        child window is created or
                                        destroyed.
 
                 WS_EX_TOPMOST          Specifies that a window created
                                        with this style should be placed
                                        above all nontopmost windows and
                                        stay above them even when CWnd is
                                        deactivated. An application can
                                        use the SetWindowPos member
                                        function to add or remove this
                                        attribute.
 
  <lpClassName>  Points to a null-terminated character string that names
                 the Windows class (a WNDCLASS struct). The class name can
                 be any name registered with the AfxRegisterWndClass
                 function or any of the predefined control-class names. It
                 must not be NULL.
 
  <lpWindowName> Points to a null-terminated character string that
                 contains the window name.
 
  <dwStyle>      Specifies the Windows style of CWnd.
 
  <x>            Specifies the initial x-position of the CWnd window.
 
  <y>            Specifies the initial top position of the CWnd window.
 
  <nWidth>       Specifies the width (in device units) of the CWnd
                 window.
 
  <nHeight>      Specifies the height (in device units) of the CWnd
                 window.
 
  <hwndParent>   Identifies the parent or owner window of the CWnd window
                 being created. Use NULL for top-level windows.
 
  <nIDorHMenu>   Identifies a menu or a child-window identifier. The
                 meaning depends on the style of the window.
 
  Remarks
 
  Creates an overlapped, pop-up, or child window with the extended style
  specified in <dwExStyle>.
 
  The CreateEx parameters specify the WNDCLASS, window title, window
  style, and (optionally) initial position and size of the window.
  CreateEx also specifies the window's parent (if any) and ID.
 
  When CreateEx executes, Windows sends the WM_GETMINMAXINFO,
  WM_NCCREATE, WM_NCCALCSIZE, and WM_CREATE messages to the window.
 
  To extend the default message handling, derive a class from CWnd, add a
  message map to the new class, and provide member functions for the above
  messages. Override OnCreate, for example, to perform needed
  initialization for a new class.
 
  Override further On<Message> message handlers to add further
  functionality to your derived class.
 
  The <dwStyle> parameter can be any combination of window styles:
 
  Return Value
 
  TRUE if the CWnd window is created; otherwise FALSE.
