WInsock SendData problem HELP
Thnaks for your proposal I will give a try.
I have an other question by the way.
How can I handle a real sychronisation between the server
and the client. This in order to get feed back from the
server that it has really accepted the connection or
detect that a connection is down from client or server
side.
Do i have to use the same SendData method for that or
should I use an other insatnce of the winsock control
dedicated fro handshaking?
thanks for your help
Regards
Serge
