            //Does NOT require to create an odbc connection in windows system
            if( IntPtr.Size == 8 ){
               // Do 64-bit stuff
                strConnectionString = string.Concat(strConnectionString, "Driver={HDBODBC};");
            }else{
               // Do 32-bit
               strConnectionString = string.Concat(strConnectionString, "Driver={HDBODBC32};");
            }
            strConnectionString = string.Concat(strConnectionString, "ServerNode=", _strServerName, ";");
            strConnectionString = string.Concat(strConnectionString, "UID=", _strLoginName, ";");

            OdbcConnection hanaConn = new OdbcConnection(strConnectionString.ToString());
