Greetings my dear folks. I really appreciate the time you spend for reading this post. So...I am NULL in the matter of network programming...but I really hope I will get it some days (the hope dies the last ), so I wanted to ask u: 1) How do I send to all computers in the LAN some info like your IP. I repeat...to ALL computers. 2) How do I send a 2 dimensional array, to the server located either on the same computer or some other PC on the LAN, please give me some specific algoritm for doing it, and desirable some C/C++ functions for doing it. Thanks, and hope to hear from you soon. Best Regards.
