InfoPath Dev

New to Infopath. I have a MFC application and i want to view and edit Forms in a dialog. 

I have loaded the IInfoPathEditor Object onto my toolbar. Dropped it into my CDialog and generated a wrapper class for it. I am experiencing some plroblems when opening the dialog and when trying to load a form (Done via the OnBnClickedButton1 method see below).

void WorkRequestDetailsDlg::OnBnClickedButton1()

{

HRESULT hr = S_OK;

OPENFILENAME ofn; // common dialog box structure

hr = OpenFileDialog("Select XML File", &ofn, "All\0*.*\0XML files\0*.xml\0");

if (FAILED(hr))

return;

// Open a form based on the solution.

m_infopathEditor.NewFromSolution(ofn.lpstrFile);

}

When opening the dialog this error occurs:

occsite.cpp line 853. The

ASSERT(!IsEqualIID(*piid, GUID_NULL)); has failed

if (SUCCEEDED(m_pObject->QueryInterface(IID_IProvideClassInfo2,

(LPVOID*)&pPCI2)))

{

ASSERT(pPCI2 != NULL);

if (SUCCEEDED(pPCI2->GetGUID(GUIDKIND_DEFAULT_SOURCE_DISP_IID, piid)))

ASSERT(!IsEqualIID(*piid, GUID_NULL));

else

ASSERT(IsEqualIID(*piid, GUID_NULL));

pPCI2->Release();

}

Then when i try opening a form the following error occurs "Library not registered". I dont know which library its looking for.

Please help!
