Call to transformNodeToObject fails

Question

I am newbie to xml and xslt area. I have written simple COM utility to transform xsl using xslt. But is failing at transformNodeToObject function call. I am using visual studio 15.

As you can see i am using the msxml6.dll import.

There was another type of call m_hrDOMInitStatus = CoCreateInstance(MSXML2::CLSID_DOMDocument60, NULL, CLSCTX_INPROC_SERVER, MSXML2::IID_IXMLDOMDocument3, (void**)&m_pDoc); Not sure whether i need to use this API

 #include "stdafx.h"
#include <windows.h>
#include "iostream"

#include <WTypes.h>
#include <comdef.h>

#include <wchar.h>

#include <vector>

#import <msxml6.dll>

using namespace MSXML2;
using namespace std;

int main()
{

    HRESULT hResult = S_OK;
    hResult = CoInitialize(NULL);

    if (FAILED(hResult))
    {
        cerr << "Failed to initialize COM environment" << endl;
        return 0;
    }

    // MSXML COM smart pointers
    // Use the Document2 class to enable schema validation
    IXMLDOMDocument2Ptr spDocSource;
    IXMLDOMDocument2Ptr spDocResult;
    IXMLDOMDocument2Ptr spDocStylesheet;
    struct IDispatch * pDispatch;

    // Create the COM DOM Document objects
    hResult = spDocSource.CreateInstance(__uuidof(DOMDocument60));
    if FAILED(hResult)
    {
        cerr << "Failed to create Source Document instance" << endl;
        return 1;
    }

    hResult = spDocResult.CreateInstance(__uuidof(DOMDocument60));
    if FAILED(hResult)
    {
        cerr << "Failed to create Result Document instance" << endl;
        return 1;
    }

    hResult = spDocStylesheet.CreateInstance(__uuidof(DOMDocument60));
    if FAILED(hResult)
    {
        cerr << "Failed to create Stylesheet Document instance" << endl;
        return 1;
    }

    // Load the source document
    spDocSource->async = VARIANT_FALSE;
    hResult = spDocSource->load("xmlinputfile.xml");
    if (hResult != VARIANT_TRUE)
    {
        cout << "Error parsing xmlinputfile.xml" << endl;
        return 1;
    }

    spDocSource->async = VARIANT_FALSE;
    hResult = spDocSource->load("XSLTFile1.xslt");
    if (hResult != VARIANT_TRUE)
    {
        cout << "Error parsing XSLTFile1.xml" << endl;
        return 1;
    }

    spDocResult->QueryInterface(IID_IDispatch, (void **)&pDispatch);
    VARIANT vResultDoc;
    vResultDoc.vt = VT_DISPATCH;
    vResultDoc.pdispVal = pDispatch;

    hResult = spDocSource->transformNodeToObject(spDocStylesheet, vResultDoc);


    if FAILED(hResult)
    {
        cout << "Error in performing transformation" << endl;
        return 1;
    }
        return 0;
        }

Answer 1

The Microsoft online examples on using MSXML with smart pointers, like https://msdn.microsoft.com/en-us/ie/ms766389(v=vs.100) , suggest that the call to transformNode would simply work as spDocSource->transformNodeToObject(spDocStylesheet, spDocResult.GetInterfacePtr()) .

I think this is due to KB of CVE-2019-1357. Does the phenomenon not stop when the following KB is uninstalled?
