注意事项

1.右键菜单中,不能出现系统命令,例如,ID_EDIT_UNDO/ID_EDIT_COPY/ID_EDIT_PASTE/ID_EDIT_CUT/ID_EDIT_SELALL等,否则,无法响应消息. 2.菜单项目,不能用OnCommand的方式进行消息处理,必须在Message Map中用ON_MESSAGE的方式,并且在头文件中实现定义好消息函数如OnMenuUndo. BEGIN_MESSAGE_MAP(CReferenceFormView, CFormView)  //{{AFX_MSG_MAP(CReferenceFormView)  ON_MESSAGE(ID_MENU_UNDO, OnMenuUndo)  ON_MESSAGE(ID_MENU_CUT, OnMenuCut)  ON_MESSAGE(ID_MENU_COPY, OnMenuCopy)  ON_MESSAGE(ID_MENU_PASTE, OnMenuPaste)  ON_MESSAGE(ID_MENU_CLEAR, OnMenuClear)  ON_MESSAGE(ID_MENU_SELECT_ALL, OnMenuSelectAll)  //}}AFX_MSG_MAP END_MESSAGE_MAP()

3.需要在FormView的OnInitialUpdate()函数或者Dialog的OnInitialDialog()函数中调用  m_ctrlRichEditReference.SetEventMask(ENM_MOUSEEVENTS);   表示RicheditCtrl的鼠标事件交由父窗体进行处理. 4.在父窗体(FormView或者Dialog)的OnNotify消息中做如下处理: BOOL CReferenceFormView::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)  {  // TODO: Add your specialized code here and/or call the base class 要点1:

The RichEditCtrl sends the message "EN_MSGFILTER" to the parent, now to get at which message has been reflected (because it could be a left click or a mouse move) we need to examine the message filter, so we cast lParam to MSGFILTER *

 MSGFILTER * lpMsgFilter = (MSGFILTER *)lParam;  要点2:   if ((wParam == IDC_RICHEDIT_REFERENCE) && (lpMsgFilter->nmhdr.code == EN_MSGFILTER)   && (lpMsgFilter->msg == WM_RBUTTONDOWN))                                            {   //if we get through here, we have trapped the right click event of the richeditctrl!    CPoint point;                                            ::GetCursorPos(&point); //where is the mouse?   CMenu menu; //lets display out context menu :)    UINT dwSelectionMade;                                          VERIFY(menu.LoadMenu(IDR_MNU_REFERENCE4RE) );     CMenu *pmenuPopup = menu.GetSubMenu(0);   ASSERT(pmenuPopup != NULL);                                          dwSelectionMade = pmenuPopup->TrackPopupMenu( (TPM_LEFTALIGN|TPM_LEFTBUTTON|TPM_NONOTIFY|TPM_RETURNCMD),    point.x, point.y, this    );

  pmenuPopup->DestroyMenu();    PostMessage(dwSelectionMade,0,0);  }    return CFormView::OnNotify(wParam, lParam, pResult); }
