VC2005 problem:IAxWinH ostWindow interface in a MFC project

[kittymaguire]

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

An assert in CComTypeInfoHol der::GetTI(LCID lcid) at

ATLASSUME(!Inli neIsEqualGUID(* m_plibid, GUID_NULL) && "Did you forget to pass the LIBID to CComModule::Ini t?");

If I ignore this assert then I get

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

at the lines in ActivateAx

CComQIPtr<IOleC lientSite> spClientSite(Ge tControllingUnk nown());

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

RedrawWindow(NU LL, NULL, RDW_INVALIDATE | RDW_UPDATENOW | RDW_ERASE | RDW_INTERNALPAI NT | 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_controlWi ndow.Create(thi s->GetSafeHwnd( ), rcClient, _T("OutlookBar. PVOutlookBar.1" ), WS_CHILD |

WS_VISIBLE | WS_CLIPCHILDREN , WS_EX_CLIENTEDG E/*,IDC_OUTLOOKBA R*/))

return false;


CComPtr<IAxWinH ostWindow> spHost;

HRESULT hr = m_controlWindow .QueryHost(&spH ost);

_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

The assertion message and the exception bith suggest that you have failed to initialise something somewhere.

0xC0000005: Access violation reading location 0x00000000.

is most normally dereference of a NULL pointer i.e.

char *p=NULL;
 
*p = 'B';
 

sorry I can not be more help, I am just not familiar enough with the classes/methods you are using.

I think you were trying to use ATL classes in MFC container app. Actually, if you want to create an ActiveX control in MFC container apps, you only need to call CWnd::CreateCon trol.
