Avatar

Level 2
Hi all,



I am trying to receive some data through TCP Socket from the
server using XMLSocketClass. Ther server is responding with some
data. But I can't access this data in my application. Pls tell me
the reasons for not working of handler private function
dataHandler(event:DataEvent):void .
