IPersistStreamInit::Save()在IE9中不工作

Question

此代码适用于IE8及更早版本。对于IE9, IPersistStreamInit::Save()返回E_NOTIMPL。任何帮助都非常感谢!

HRESULT CHtmlCtrl::GetDocumentHTML(CString& strHTML) const
{
    HRESULT hr = E_NOINTERFACE;
    CComPtr<IHTMLDocument2> spHTMLDocument;
    GetHtmlDocument()->QueryInterface(IID_IHTMLDocument2, (LPVOID*)&spHTMLDocument);
    if (spHTMLDocument)
    {
        CComQIPtr<IPersistStreamInit> spPSI;
        spPSI = spHTMLDocument;
        if (spPSI)
        {
            CStreamOnCString stream;
            hr = spPSI->Save(static_cast<IStream*>(&stream), FALSE);
            if (hr == S_OK)
            {
                if (!stream.CopyData(strHTML))
                    hr = E_OUTOFMEMORY;
            }
        }
    }
    return hr;
}

似乎是MFC中的一个bug，正如这里所描述和确认的。修复了Visual Studio 2012 RTM
