I have a floating CToolbar in the CMainframe.  When the user closes the toolbar using the toolbar's [X] button, does the toolbar notifies the parent mainframe?

If yes, how do i catch this notification message?

If no, what should i do so that my Mainframe is aware that the toolbar has been closed by the user?

It doesn't work.  

The CMyToolBar::OnClose() wasn't called when the user closes the CMyToolBar using the toolbar's [x] button.

Just implement the CMyToolBar as inpras has mentioned. But override the OnWindowPosChanged(WINDOWPOS FAR* lpwndpos) function. Write some codes like this:

      if (lpwndpos->flags & SWP_HIDEWINDOW)
      {
            //Here is your notification code;
      }

Do as inpras suggested
but map WM_SYSCOMMAND message
in the sys command handler add the following lines

void CMyToolBar::OnSysCommand(UINT nID, LPARAM lParam)
{
      if ((nID/* & 0xFFF0*/) == SC_CLOSE)
      {
// your toolbar is being closed
// notify parent
// say
GetParent()->PostMessage(WM_COMMAND, ID_TOOLBARCLOSING);
      }
      else
      {
            CToolBar::OnSysCommand(nID, lParam);
      }
}

and be sure you have changed
CToolBar m_wndToolBar;
to
CMyToolBar m_wndToolBar;

in your CMainFrame cpp file

Hope this helps

NutsNuts's answer works.

vachooho's suggestion of using WM_SYSCOMMAND doesn't works in my application.  The void CMyToolBar::OnSysCommand(UINT nID, LPARAM lParam) is never called.

Thank you guys.
