I have recently started creating chat server, and client programs for my friends and I to use where the server program would be run on my computer, and I would give the client program to my friends to chat etc. when I use the

SockAddr.sin_addr.s_addr = inet_addr("127.0.0.1");

if(connect(sConnect,(SOCKADDR*)(&SockAddr),sizeof(SockAddr))!=0);

section of code it works perfect on my computer, I can connect, and everything works perfectly, but if I change the 127.0.0.1 to my real ip (just for example lets say that its 11.11.11.11) the client program wont connect. (obviously i do this so that the client program wont try to connect to a port on my friends computer where it will be run, but it will connect to one of the ports on mine)

any help would be appreciated

How did you create sConnect?
sConnect = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);??

If you really don't change anything but IP address and make no mistake in the address, I smell firewall!
Check up firewall logs, look at the firewall settings, consider using different protocol…

When you say real address do yen mean your computer's IP or your external internet IP?
If you are using your internet address, and have a router then you may need to set up port forwarding on your router, or use upnp to do it for you.
