// CMessageBox dialog
// Simon FitzMaurice, October 1998
//
// CMessageBox replicates the functionality of CWnd::MessageBox(), but also
// allows the creation of custom and modeless messageboxes.
//
// Use the 3-parameter constructor and DoModal() to obtain the usual results.
// [Create() may be used to invoke a modeless dialog]
// All flags described in "Message-Box Styles" are supported with the
// exception of MB_TASKMODAL (not useful within an MFC app).
// In addition, two new styles are available: MB_YESNOALL and MB_YESNOALLCANCEL.  These
// add "Yes All" and "No All" buttons to the normal MB_YESNO and MB_YESNOCANCEL,
// respectively (with ids of IDYESALL and IDNOALL).  The MB_DEFBUTTON(n) macro 
// may be used to extend extend the series MB_DEFBUTTON1, MB_DEFBUTTON2, 
// MB_DEFBUTTON3 ...
//
// Use the parameterless constructor to customize the messagebox.  Buttons must
// be added [using AddButton()] and other attributes changed before calling 
// DoModal() or Create().
//
// In the case of Create(), the CMessageBox object must be allocated on the heap;
// it deletes itself when the dialog is dismissed.  The parameters of Create()
// may be used to specify that the parent be sent a notification message when 
// this happens.
