Instead of ReceiveStr, call Receive to be able to get winsock.recv return code. This return code is -1 if some error occure, 0 is remote has gracefully closed or a positive integer to telle how many bytes you have received.
Usually you can safely ignore any OnDataAvailable where Receive return <= 0. -- Contribute to the SSL Effort.
