Error when passing connectin string to activeX

Mar 26 2013 12:44 PM
Hello all
 
I am using ActiveX in my web application in one page, it is working properly in my PC, i am passing the connection string from the web page that has the activex in it as following:
 
This is the javascript code in the page that passing the connection string to the activex:
 

<script language="javascript" type="text/javascript">       function Connect() {           var doc = document.forms[0];             var PrinterControl = document.applets('PrinterObject1');           PrinterControl.UserText = document.form1.hdnConString.value + ',' + document.form1.hdnCategory.value + ',' + document.form1.hdnLoginID.value + ',' + document.form1.hdnPassword.value + ',' + document.form1.hdnCategoryType.value;         }                 </script>   <body  önload="Connect()">     <form id="form1"  runat="server" > . . . . </form> </body>

and in the activeX code i receive the connection string and other values as following: 
 
 public String UserText         {             get              {                  return conString;              }             set             {                  conString = value;                                   string[] arrID = conString.Split(',');                  conStr = Convert.ToString(arrID[0]);                  category = Convert.ToString(arrID[1]);                  loginID = Convert.ToString(arrID[2]);                  password = Convert.ToString(arrID[3]);                  categoryType = Convert.ToString(arrID[4]);             }         }
