I've been writing a client side socket in C++ from a tutorial, and I haven't quite gotten my head around some of it yet. I've included many windows library headers, but none of them appear to be recognized by the compiler. It begins flagging every identifier in these libraries as undefined and even some of the ones I have created myself. The editor recognizes the code as completely correct, and tells me there are no issues, but the compiler throws over a hundred errors, most all linked to an undeclared identifier.
Some examples of supposedly undeclared identifiers include WSADATA, send(), and some of the most basic functions and classes from these headers. I included the header files windows.h, iostream, winsock2.h, ws2tcpip.h, and fstream. I initialized the socket libraries with "#pragma comment(lib, "Ws_32.lib")". Whatever help you can give is much appreciated.
Try to include winsock2.h before windows.h

And also compile with -lws2_32 parameter.

He already did pragma comment (lib,"ws232");

How would I add a parameter to Visual Studio? I probably shouldn't be using a platform like that, but it's the only one I'm comfortable with at the moment.

The fact that this eliminated so many error messages doesn't seem right to me. That is that something so trivial would matter so much.

yes, try winsock2.h before windows.h, if you are having linker issues, yeah, you might try and add ws2_32.lib from your solution->properties->linker->input

He didn't know what he was talking about, don't listen to him. That command line linker option isn't even for the MS compiler.

Post your errors.
You probably need to link the library with the functions.
