      sl := TStringList.Create;
      try
        ms := TMemoryStream.Create;
        try
          sl.Text := HTMLCode;
          sl.SaveToStream(ms);
          ms.Seek(0, 0);
          (WebBrowser1.Document as IPersistStreamInit).Load(TStreamAdapter.Create(ms));

    WebBrowser1.Navigate('about:blank');
    HTMLDocument := WebBrowser1.Document as IHTMLDocument2;
    HTMLDocument.write(PSafeArray(TVarData(vv).VArray));
