MFC 中 WM_NOTIFY messages 传递过程

// ListDlg.h : header fileclass CListDlg : public CDialog{// Overrides// ClassWizard generated virtual function overrides//{{AFX_VIRTUAL(CListDlg)public:virtual BOOL OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo);protected:virtual BOOL OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult);//}}AFX_VIRTUAL// Implementationprotected:// Generated message map functions//{{AFX_MSG(CListDlg)afx_msg void OnItemchangedListMeasure(NMHDR* pNMHDR, LRESULT* pResult);//}}AFX_MSGDECLARE_MESSAGE_MAP()}

 

 // ListDlg.cpp : implementation fileBEGIN_MESSAGE_MAP(CListDlg, CDialog)//{{AFX_MSG_MAP(CListDlg)ON_NOTIFY(LVN_ITEMCHANGED, IDC_LIST_MEASURE, OnItemchangedListMeasure)//}}AFX_MSG_MAPEND_MESSAGE_MAP()BOOL CListDlg::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult){return CDialog::OnNotify(wParam, lParam, pResult);}BOOL CListDlg::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo) {return CDialog::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);}void CListDlg::OnItemchangedListMeasure(NMHDR* pNMHDR, LRESULT* pResult) {NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;// TODO: Add your control notification handler code here*pResult = 0;}

 

 

 

WM_COMMAND messages传递过程与上述相似。
