HRESULT hResult;
IVdsService* pService = NULL;
IVdsServiceLoader *pLoader = NULL;

//Launch the VDS Service
hResult = CoInitialize(NULL);
if( SUCCEEDED(hResult) )
{
    hResult = CoCreateInstance( CLSID_VdsLoader,
                NULL,
                CLSCTX_LOCAL_SERVER,
                IID_IVdsServiceLoader,
                (void**) &pLoader
                );

    //if succeeded load VDS on local machine
    if( SUCCEEDED(hResult) )
        pLoader->LoadService(NULL, &pService);

    //Done with Loader now release VDS Loader interface
    _SafeRelease(pLoader);

    if( SUCCEEDED(hResult) )
    {
        hResult = pService->WaitForServiceReady();
        if ( SUCCEEDED(hResult) )
        {
            AfxMessageBox(L"VDS Service Loaded");
            IEnumVdsObject* pEnumVdsObject = NULL;
            hResult = pService->QueryProviders(VDS_QUERY_SOFTWARE_PROVIDERS, &pEnumVdsObject);

            IUnknown* ppObjUnk ;

            ULONG ulFetched = 0;

            hResult = E_INVALIDARG;
            while(!SUCCEEDED(hResult))
            {
                hResult = pEnumVdsObject->Next(1, &ppObjUnk, &ulFetched);
                hResult = ppObjUnk->QueryInterface(IID_IVdsSwProvider, (void**)&pVdsSwProvider);
                if(!SUCCEEDED(hResult))

                hResult = pEnumVdsObject->Next(1, &ppObjUnk, &ulFetched);
                hResult = ppObjUnk->QueryInterface(IID_IVdsPack, (void**)&pVdsPack);
                if(!SUCCEEDED(hResult))
                    _SafeRelease(ppObjUnk);
            }

            _SafeRelease(pEnumVdsObject);
            _SafeRelease(ppObjUnk);

            hResult = pVdsPack->QueryVolumes(&pEnumVdsObject);
            pEnumVdsObject->Reset();

            hResult = E_INVALIDARG;
            ulFetched = 0;
            BOOL bDone = FALSE;
            while(!SUCCEEDED(hResult))
            {
                hResult = pEnumVdsObject->Next(1, &ppObjUnk, &ulFetched);
                hResult = ppObjUnk->QueryInterface(IID_IVdsVolume, (void**)&pVdsVolume);
                if(!SUCCEEDED(hResult))
                    _SafeRelease(ppObjUnk);
            }
            _SafeRelease(pEnumVdsObject);
            _SafeRelease(ppObjUnk);
