Hi, I have a simple client-server TCP/IP server working ok and I now want to change it over to the UDP protocol rather than TCP but I am having a few problems - possibly because I''m not 100% sure about what is required when establishing a UDP connection. Can anybody tell me if this is the correct method. 1. Start up winsock on both applications 2. Create sockets of type SOCK_DGRAM on each application 3. Bind sockets on both applications 4. Use sendto and recvvfrom to send and recieve data. Am I missing anything. I think I am correct in that there is no need to listen() and connect() with a UDP connection. Is it correct to send and recieve over the one socket that has been created on each application. This is just a win32 console application at this stage. I can post some code if needed but your help on these concepts would be appreciated so I can see if I''m on the correct track. Thanks henry

That''s it.

If you want to check your code against something that works.
You can find a UDP client / server here.
