Connect to outlook from C++

[verasen]

Outlook 2007 uses the MS Word editor for composing/viewing emails. I'm trying to get a handle to the Word object within outlook and have most of the code. There's one line that's giving me an error and I'm not sure how to get around it. The compiler refuses to compile because of the line which says QueryInterface. The error is "error C2787: 'MSWord::_Document' : no GUID has been associated with this object". I've been breaking my head over this for hours. Anyone know how to fix this?

#include "stdafx.h"
#include "./MSWord/msword8.h"
 
// Define this according to the Outlook Object
// Model version you are compiling under
#define OUTL12    // Outlook 2007
 
#pragma warning(disable:4146)
 
#if defined(OUTL12) // Outlook 2007
    #import "C:\Program Files\Common Files\Microsoft Shared\OFFICE12\mso.dll" \
        no_namespace
    #import "C:\Program Files\Microsoft Office\OFFICE12\msoutl.olb" \
        rename_namespace("Outlook")
#endif // OUTL12
 
#pragma warning(default:4146)
 
void GetOutlookWordEditor (MSWord::_Application *pWordApp)
{
    CLSID clsid;
    LPUNKNOWN pUnk;
    CLSIDFromProgID(L"Outlook.Application", &clsid);
    HRESULT hr = ::GetActiveObject(clsid, NULL, &pUnk);
    if (SUCCEEDED(hr))
    {
        // Get IDispatch
        IDispatch *pDispApp;
        HRESULT hr = pUnk->QueryInterface(IID_IDispatch, (void **)&pDispApp);
 
        if (FAILED(hr))
        {
            return;
        }
 
        pUnk->Release();
 
        Outlook::_ApplicationPtr outlookApp(pDispApp);
 
        if(outlookApp->ActiveInspector()!=NULL)
        {
            Outlook::_InspectorPtr pInsp(outlookApp->ActiveInspector());
            if(pInsp!=NULL)
            {
                IDispatch *pDispWordEditor;
                MSWord::_Document document;
 
                 if (SUCCEEDED(pInsp->get_WordEditor(&pDispWordEditor)))
                 {
                    pDispWordEditor->QueryInterface(__uuidof(MSWord::_Document), (LPVOID *)&document);
                 }
            }
        }
    }
    return;
}
