Now, i get this error: Unhandled exception at 0x00530a33 in MyPrg.exe: 0xC0000005: Access violation reading location 0x1271e40a. and control goes to: void CWnd::SetWindowText(LPCTSTR lpszString) { ENSURE(this); ENSURE(::IsWindow(m_hWnd) || (m_pCtrlSite != NULL)); if (m\_pCtrlSite == NULL) ::SetWindowText(m\_hWnd, lpszString); else **m\_pCtrlSite->SetWindowText(lpszString);// control points here** }
