hi Friends,
I'm making Voice Chat application.
What I'm doing is:
*First record the message and then send.
*At the receiving side I'm able to get only one packet and others are lost.
Is it possible that using some Multithreading features..i can spawn some
process which handles the streaming of outgoing data and incoming data.
Or can ne one suggest some thing related to this application..so that data
shud appear stream properly.
