void CMyDlg::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); // TODO: Add your message handler code here if (IsWindow(m_ListCtrl.m_hWnd)) { CRect rect; GetClientRect(rect); m_ListCtrl.MoveWindow(rect); m_ListCtrl.SetBkImage(::LoadBitmap(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BKIMAGE))); } } problem still unresolved, autofit(stretch) no effect! Thanks!
