hello friends,

I have two program: receive.cpp and send.cpp

They re very simple, when compiling there is no error in both.

I only wanna see them to talk to each other but when run these progs,

both of them gives 10061 error. Below the codes, firstly receive.cpp:

thanks my friend, I read the note but I still cant solve the problem.

my LAN ip is <snip>
I wonder that: if I must change the adress in the both program codes
to that ip or it must stay the same "127.0.0.1" ?

don't know --- try 127.0.0.1 and find out if it fixes your problem.

I do not see any Listen for port number in any of the applications ?
if you have setup listening for the ports in some way I do not know about, then perhaps your problem could be Firewall or Antivirus program blocking the attempt to connect to port
