Using the MSHTML collection with a string containing HTML

I'm request html using the following method,


      Dim sResult As String
                        Dim oHttp As HttpWebRequest
                        Dim objResponse As WebResponse
                        Dim objRequest As WebRequest = System.Net.HttpWebRequest.Create(EventUrl)




                        objRequest.Method = "GET"
                        objRequest.Timeout = 120000 ' 20 sec.
                        objResponse = objRequest.GetResponse

                        Dim sr As System.IO.StreamReader = New System.IO.StreamReader(objResponse.GetResponseStream(), System.Text.Encoding.UTF7)

                        sResult = sr.ReadToEnd()
                        ' Close and clean up the StreamReader
                        sr.Close()

debug.write(sresult.tostring)

                        Dim DOCHTML As String
                        doc = DirectCast(sResult, mshtml.HTMLDocument)
                        dochtml = doc.documentElement.innerHTML()
                        Debug.Write(DOCHTML)


This doesn't seem to convert the html string so that it can be used with the mshtml collection. If I choose to display the html after it finishes with debug.write(sresult.tostring) it will output to the debug window. But when I try to output it with  Debug.Write(DOCHTML) it won't work. 500 points because I'm trying to finish the development of this application within the next few weeks. thanks guys.
