救救我这个菜鸟啊~~~~listctrl的问题

   对了，都是运行时提示"afxcmn.inl"……然后按retry,有个小箭头指向：
_AFXCMN_INLINE int CListCtrl::InsertColumn(int nCol, const LVCOLUMN* pColumn)
-〉〉〉〉 { ASSERT(::IsWindow(m_hWnd)); return (int) ::SendMessage(m_hWnd, LVM_INSERTCOLUMN, nCol, (LPARAM)pColumn); }
_AFXCMN_INLINE BOOL CListCtrl::DeleteColumn(int nCol)
