My program (C++, winsock, Windows 8, 10) sends UDP broadcast message to invite other computers to make connection via TCP.
Therefore, the program receives this (own) message just like other computers too.
The question is: how can I find out that my program has got your own message ?
One way I see is to generate unique number (key), send it with broadcast message, analyze it when the message received – if matches the unique key, then it is own message.
Are there more simple way ?
