When I try to build it into an EXE, this is the error I keep getting. Any ideas on what this may be from? --------------------Configuration: main - Win32 Release--------------------
Linking...

When a compiler generates such errors it's (very often) because it doesn't recognise the used commands/variables/ops/function calls
.
In your case, the unrecognized are:
_listen@8
_closesocket@4
and so on... (you get it)..
those function calls are surely, like SilentRage said, defined in the wsock32.lib .....
Yep...
that's why.
Hope you got some light into it,,,

Just in case you don't need IMP files with every non-template header, I didn't know. I'm fairly new to C++. | | |
