I used to add "afx_msg" prefix at declaration of message handler function.
But I found the function still called whithout the prefix.
Is "afx_msg" nessary?

class CVLManageDlg : public CDialog  
{    ...
protected:   
    void OnAdd();
    void OnModify();
    void OnDel();
}


BEGIN_MESSAGE_MAP(CVLManageDlg, CDialog)
    ON_BN_CLICKED(IDC_ADD_VL_MANAGE, OnAdd)
    ON_BN_CLICKED(IDC_MD_VL_MANAGE, OnModify)
    ON_BN_CLICKED(IDC_DEL_VL_MANAGE, OnDel)
    ON_NOTIFY(NM_CLICK, IDC_LIST_VL_MANAGE, OnClickList)
    ON_WM_SIZE()
