Javascript reference in ExcelWebAddIn Project

Hi

To use the following code in my JavaScript what reference would I have to make
"Microsoft ActiveX Data Objects 6.0 Library" and it didn't work

          connection = new ActiveXObject("ADODB.Connection");

            var ConnString = "Provider=SQLOLEDB;Data source=xxx;Initial catalog=Demo1;User Id=xxx;";
            connection.open(ConnString);
            var rs = new ActiveXObject("ADODB.Recordset");
            rs.Open("SELECT [Company] FROM [Contacts]", connection);
            rs.MoveFirst();
            while (!rs.eof) {
                document.write(rs.fields(1));
                rs.MoveNext();
            }
            rs.close();
            connection.close();

Select allOpen in new window
