In my app, there are some toolbars and an user can show/hide them freely
just as "docktool" sample in [MSDN]does. I make a pop-up Menu to set
show/hide them toolbars as follows,

BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_RBUTTONDOWN)
{
CWnd* pWnd = CWnd::FromHandlePermanent(pMsg->hwnd);
CControlBar* pBar = DYNAMIC_DOWNCAST(CControlBar, pWnd);

if (pBar != NULL)
  {
  CMenu Menu;
  CPoint pt;

  pt.x = LOWORD(pMsg->lParam);
  pt.y = HIWORD(pMsg->lParam);
  pBar->ClientToScreen(&pt);

  if (Menu.LoadMenu(IDR_TOOLBAR))
  {
   CMenu* pSubMenu = Menu.GetSubMenu(0);

   if (pSubMenu!=NULL)
   {
    pSubMenu->TrackPopupMenu(TPM_LEFTALIGN |
TPM_RIGHTBUTTON,pt.x,pt.y,this);
   }
  }
}
}
return CFrameWnd::PreTranslateMessage(pMsg);
}

I hope the pop-up Menu will be showed only when I right-click their
toolbars. But when I right-click the statusbar of app, the pop-up Menu
also appears. That is, pBar is not equal to NULL.
So, how can I distinguish between CControlBar and CStatusBar?

Have you considered overriding WM_RBUTTONDOWN in a CControlBar-derived class
that both of your bars derive from? That's much more encapsulated than
doing it in MainFrame.

Also instead of looking at WM_RBUTTONDOWN, check out WM_CONTEXTMENU which is
generated when the right-click occurs in many cases.
