• A dialog bar is not quite similar to a dialog box, although both can be based on a dialog template.
  That because CDialogBar is not derived from CDialog but from CControlBar.
  
• OnDraw is a virtual member function of CView which is called from within WM_PAINT message handler (OnPaint). Neither CDialog, nor CDialogBar have OnDraw method.
  
• If you need a text in a dialog box or a dialog bar is easier to put it in a static or edit control rather than drawing it in WM_PAINT message handler.
