How to change the page encoding in Web Browser AxtiveX control? Currently I make:

    HRESULT hr;
    CComPtr<IDispatch> disp = this->GetHtmlDocument();
    CComPtr<IHTMLDocument2> m_doc = NULL;
    hr = disp->QueryInterface(&m_doc);
    if (SUCCEEDED(hr))
    {
        m_doc->put_charset(CComBSTR("windows-1251"));

        CComPtr<IHTMLElementCollection> m_pElemCollection;
        CComBSTR Text;


        hr = m_doc->get_all(&m_pElemCollection); // get collection
        if (SUCCEEDED(hr))
        {
            long cntr;
            hr = m_pElemCollection->get_length(&cntr); // get lenght

            if (SUCCEEDED(hr))
            {

                for (int i = 0; i<cntr; i++) // all collection
                {
                    VARIANT vIndex;

                    vIndex.vt = VT_I4;
                    vIndex.intVal = i;
                    IDispatch* pDisp = NULL;
                    m_pElemCollection->item(vIndex, vIndex, &pDisp);

                    IHTMLMetaElement* m_Meta = NULL;
                    hr = pDisp->QueryInterface (&m_Meta);
                    if (SUCCEEDED(hr))
                    {
                        m_Meta->put_charset(CComBSTR("windows-1251"));
                        m_Meta->Release();
                    }

                    pDisp->Release();

                }
            }
        }

    // hr = m_doc->put_defaultCharset(CComBSTR("windows-1251"));

    // CComPtr<IHTMLLocation> pLoc = NULL;
    // m_doc->get_location (&pLoc);

    // hr = pLoc->reload(VARIANT_FALSE);

    }
and nothing changes, it doesn't work. Could you please advise on what to do?

Anybody know this problem decision?
Please help.
