首先定义右键消息函数：

    afx_msg  void  OnRBClick(NMHDR* pNMHDR, LRESULT* pResult);    

    然后在消息循环中定义消息对应关系：

    ON_NOTIFY(NM_RCLICK, ID_TREECTRL, OnRbClick)

    接着定义消息函数内容：

    void OnRBClick(NMHDR* pNMHDR, LRESULT* pResult)

    {

           CPoint point;

           GetCursorPos(&point);

           CPoint pointInTree = point;

           m_TreeCtrl.ScreenToClient(&pointInTree);

           HTREEITEM item;

           UINT flag = TVHT_ONITEM;

           item = m_TreeCtrl.HitTest(pointInTree, &flag);

           if(item != NULL)

           {

                  m_TreeCtrl.SelectItem(item);

                  CMenu menu;

                  menu.LoadMenu(IDR_MENU1);

                  menu.GetSubMenu(0)->TrackPopupMenu(TPM_LEFTALIGN | 

                             TPM_RIGHTBUTTON, point.x, point.y, this, NULL);

           }

    }
