If i want a client-server app, do i need to have 2 sockets on each computer, one for sending and one for recieving, or is there a way to use just the one socket for input & output? Cheers, Steve Steve

Just one client socket for input and output

This is what i do:
Client:
Create
Connect
Send
Close
And that works fine.

Server:
Create Socket
Listen
Accept
Send
Close
But the client doesn''t get any data from the server (or the server doesn''t send it)

Any ideas whats missing?

this might not be right but...

I think you''re missing a recv() call somewhere in there

int recv(int sockfd, void *buf, int len, unsigned int flags);

sockfd is socket definition, *buf is where you''re recieving it, len is maximum length *buf can be, and flags I leave as 0.

hope thats right

I''ve fixed it now, i wasn''t doing a WSAAsyncSelect(...,FD_READ) if this was a client.
