public string sendRequestXML(string ticket, string strHCPResponse, string strCompanyFileName,
            string qbXMLCountry, int qbXMLMajorVers, int qbXMLMinorVers)
        {


            if (Session["counter"] == null)
            {
                Session["counter"] = 0;
            }
            string evLogTxt = "WebMethod: sendRequestXML() has been called by QBWebconnector" + "\r\n\r\n";
            evLogTxt = evLogTxt + "Parameters received:\r\n";
            evLogTxt = evLogTxt + "string ticket = " + ticket + "\r\n";
            evLogTxt = evLogTxt + "string strHCPResponse = " + strHCPResponse + "\r\n";

            if (count < total)
            {
                request = req[count].ToString();
                evLogTxt = evLogTxt + "sending request no = " + (count + 1) + "\r\n";
                Session["counter"] = ((int)Session["counter"]) + 1;
            }
            else
            {
                count = 0;
                Session["counter"] = 0;
                request = "";
            }
