Q:

Winsock Programming

I have had nothing but trouble with Winsock since I started using it.  I cannot seem to initialize Winsock to save my life.  I'm not asking for anyone to write the whole program ( As I know how annoying that is ) I just need help with Winsock.  I have tried several compilers and always get weird errors.

Here is my code:
#include <cstdlib>
#include <iostream>
#include <string.h>
#include <winsock2.h>

int iReqWinsockVer = 2;

using namespace std;

int main()
{
    cout<<"Initializing Winsock 2...\n";

    // WINSOCK INITIALIZATION

WSADATA wsaData;

if (WSAStartup(MAKEWORD(iReqWinsockVer,0), &wsaData)==0) {
    // Check if major version is at least iReqWinsockVer
    if (LOBYTE(wsaData.wVersion) >= iReqWinsockVer) {
        // Network stuff here
    }
    else {
        // Required version not available
    }

    // Cleanup winsock
    if (WSACleanup()!=0) {
        // cleanup failed
        }
    }
else {
    //  startup failed
}
    // END WINSOCK INITIALIZATION

        system("PAUSE");
    }

A:

Add ws2_32.lib as linker input. 
Project Properties->linker->input page
On that page you will see Additional Dependencies. 
Put it in there - note that library names should be seperated with spaces
Or you could add this line directly to your source file:
#pragma comment(lib, "ws2_32.lib")
