classic asp/asp.net web services

I create a classic asp bridge to call the webservices. The webservices url is working properly. I have the following code, and how can i call to get the result from "SendEncryption"?



Private function EncryptionRequestString()
            Dim p
            p = "<?xml version=""1.0"" encoding=""utf-8""?>"
                p = p & "<s:Envelope xmlns:s=""http://www.w3.org/2003/05/soap-envelope"" xmlns:a=""http://www.w3.org/2005/08/addressing"">"
            p = p & "  <s:Header>"
            p = p & "   <a:Action s:mustUnderstand=""1"">" & m_soapActionEncryption & "</a:Action>"
            p = p & "   <a:To s:mustUnderstand=""1"">" & m_serviceUrl & "</a:To>"        
            p = p & "  </s:Header>"
                p = p & "  <s:Body>"
            p = p & "    <RequestEncryption xmlns=""" & m_xmlns & """>"
            p = p & "       <plainText>" & m_WsOnlineEncryptionAndDecryption.StringText & "</plainText>"        
            p = p & "       <accessCode>" & m_accessCode & "</accessCode>"
            p = p & "    </RequestEncryption>"
                p = p & "  </s:Body>"
                p = p & "</s:Envelope>"
                EncryptionRequestString = p      
End Function

Public function SendEncryption()
            Dim objRequest, objXMLDoc
            Dim strRet, strRequest
        On Error Resume Next
        strRequest = EncryptionRequestString()
            Set objRequest = CreateObject("MSXML2.ServerXMLHTTP")
            objRequest.open "POST", m_serviceUrl , false
            objRequest.setRequestHeader "Content-Type", m_content_type
            objRequest.setRequestHeader "Content-Length",CStr(Len(strRequest))
            objRequest.setOption 2, 13056  
            objRequest.send strRequest
            strRet = ErrHandlerXMLHTTPRequest(objRequest, strRequest)
        set objRequest = nothing
        SendEncryption =  strRet
End function
