    using socket to communicate between programs on one computer

    Hi,
    I have to separate programs. Usually they would be located on different computers and communicate between themselves using the CSocket class. My question is for testing purposes, can I run the two programs on 1 computer and then have one send data to a port A and the other one read data from port A. Would that work. Thanks

    Sure, just pick two different ports and 127.0.0.1 as the host, it should work.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Correct.

    True for TCP: once a process is listening on a port, no other processes can listen on that same port. Many processes can connect to the same port.
