使用类CGfxOutBarCtrl类，在响应消息点击消息的时候，

long CMainFrame::OnOutbarNotify(WPARAM wParam, LPARAM lParam)
{
    switch (wParam)
{
  case NM_OB_ITEMCLICK:
  // cast the lParam to an integer to get the clicked item
   {
    int index = (int) lParam;
    CString cs;
       cs = m_OutBar.wndBar.GetItemText(index);
        ReleaseCapture();//释放鼠标扑捉－－－－－－－－－－－－－－－－！！！！！！！！！！！！
          //执行弹出模式对话框后，CMyDialog dlg; dlg.DoModal();出现问题。

   }
  return 0;
  case NM_OB_ONLABELENDEDIT:
  // cast the lParam to an OUTBAR_INFO * struct; it will contain info about the edited item
  // return 1 to do the change and 0 to cancel it
   {
    OUTBAR_INFO * pOI = (OUTBAR_INFO *) lParam;
    TRACE2("Editing item %d, new text:%s/n", pOI->index, pOI->cText);
   }
  return 1;
  case NM_OB_ONGROUPENDEDIT:
  // cast the lParam to an OUTBAR_INFO * struct; it will contain info about the edited folder
  // return 1 to do the change and 0 to cancel it
   {
    OUTBAR_INFO * pOI = (OUTBAR_INFO *) lParam;
    TRACE2("Editing folder %d, new text:%s/n", pOI->index, pOI->cText);
   }
  return 1;
  case NM_OB_DRAGITEM:
  // cast the lParam to an OUTBAR_INFO * struct; it will contain info about the dragged items
  // return 1 to do the change and 0 to cancel it

Trick: How to open a modal dialog from the OnOutbarNotify funtion

--------------------------------------------------------------------------------
Since may have written to me reporting trouble when trying to execute a modal dialog box from within the OnOutbarNotify function, here's the trick;
- add ReleaseCapture(); before opening your dialog

The trouble is related to how the bar control capture the mouse to get the hoover look; if the control has capture (as is always the case in this function), no modal will be correctly executed until you release the mouse capture, with the function above.
