      When I tried to use the IAxWinHostWindow interface in a MFC project I get the following

      An assert in CComTypeInfoHolder::GetTI(LCID lcid) at

      ATLASSUME(!InlineIsEqualGUID(*m_plibid, GUID_NULL) && “Did you forget to pass the LIBID to CComModule::Init?”);

      If I ignore this assert then I get

      Unhandled exception at 0x0176cfa8 in testcontAINER.exe: 0xC0000005: Access violation reading location 0x00000000.

      at the lines in ActivateAx

      CComQIPtr spClientSite(GetControllingUnknown());

      hr = m_spOleObject->DoVerb(OLEIVERB_INPLACEACTIVATE, NULL, spClientSite, 0, m_hWnd, &m_rcPos);

      RedrawWindow(NULL, NULL, RDW_INVALIDATE | RDW_UPDATENOW | RDW_ERASE | RDW_INTERNALPAINT | RDW_FRAME);

      The code to create the control is as below, where m_controlWindow is a

      CAxWindow

      RECT rcClient;

      GetClientRect(&rcClient);

      AtlAxWinInit();

      USES_CONVERSION;

      if(!m_controlWindow.Create(this->GetSafeHwnd(), rcClient, _T(“OutlookBar.PVOutlookBar.1”), WS_CHILD |

      WS_VISIBLE | WS_CLIPCHILDREN, WS_EX_CLIENTEDGE/*,IDC_OUTLOOKBAR*/))

      return false;

      CComPtr spHost;

      HRESULT hr = m_controlWindow.QueryHost(&spHost);

      _bstr_t str(“OutlookBar.PVOutlookBar.1”);

      hr = spHost->CreateControl(str, m_controlWindow, 0);

      I can create the control in the ATLCon example for VC2005 but not in an MFC Container App created using VC2005.

      Does anyone know why this is not working and how I can fix it.

      Thanks

      Katherine
