- I have a class that extends CSocketComm, it is a socket server

- after client send data to server (OnDataReceived function), how can
I send back some data to client? i think i should put the code inside
(OnDataReceived function).

- Currently (OnDataReceived function) only receive data from client
and insert data into a link list - (m_listMessages)

- any example code on response data back to client like -
<resp><picID>2</picID></resp>
