Winsock client/server - server socket error

[x-ice]

I am making a winsock client/server char application as suggested by my programming lecturer (because I have finished all his work for now). When I attempt to create a socket it fails. Here is my code:

SimpleCharServer.cpp

#include <iostream>
#include <winsock2.h>
#include <wininet.h>
#include <sys/types.h>
#include <string>

#include "SimpleChatServer.h"

using namespace std;

const char ipAddress[16] = "127.0.0.1";
const int portNum = 4444;
const int MAX_USERS = 10;
const int BUFFER_SIZE = 50;
const int REQ_WINSOCK_VER = 2;
const int QUEUE_SIZE = 5;

int main(void)
{
	//Array of 'connectedUser' structures to hold a list of hosts connected
	//connectedUser currentUsers[MAX_USERS]; //Enough space for 10 users

	//Show welcome message
	showWelcomeMsg();

	struct sockaddr_in clientIn;
	struct sockaddr_in serverIn;
	//Buffer to messages
	char txtBuffer[BUFFER_SIZE];

	WSADATA wsaData;

	serverIn.sin_family = AF_INET;
	serverIn.sin_addr.s_addr = htonl(INADDR_ANY); 
	serverIn.sin_port = htons(portNum);

	SOCKET hSocket;

	if(WSAStartup(MAKEWORD(REQ_WINSOCK_VER,0), &wsaData)==0)
	{
		//Create a socket
		if(hSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)==0) //Create socket success
		{
			cout << "Socket created" << endl; //TEST

			//Bind the socket to socket address
			bind(hSocket,(struct sockaddr*)&serverIn,sizeof(serverIn)); //Bind socket success
			
			cout << "Socket bound" << endl; //TEST

			listen(hSocket, QUEUE_SIZE); //Listening
			
			cout << "Listenining on socket" << endl; //TEST

			int addrLen;

			bool errOccur = false;
			
			while(!errOccur) //Infinate loop, see Glenn about it
			{
				//Wait for a connection, then accept it
				accept(hSocket,(struct sockaddr*)&clientIn, &addrLen);
				//Receive the data that was sent
				if(recv(hSocket,txtBuffer, sizeof(txtBuffer),0)==0)
				{
					//Print the message
					printMessage(txtBuffer);
					//Send data back to all clients	
					send(hSocket, txtBuffer, strlen(txtBuffer),0);
				}
			}
		}
		else
		{
			cout << "Error: Unable to create socket" << endl;
		}
	}
	//Close the socket
	closesocket(hSocket);

	//Winsock cleanup routine
	WSACleanup();
	cout << "Server shutting down" << endl;

	return 0;
}

void printMessage(char *txtBuffer)
{
	cout << txtBuffer << endl;
}

void showWelcomeMsg()
{
	cout << "===============================================================================" << endl;
	cout << "=                                                                             =" << endl;
	cout << "=                              SIMPLE CHAT SERVER                             =" << endl;
	cout << "=                                                                             =" << endl;
	cout << "=                               BY DANIEL MORGAN                              =" << endl;
	cout << "=                                                                             =" << endl;
	cout << "===============================================================================" << endl << endl;
}

SimpleChatServer.h

#ifndef SIMPLE_CHAT_SERVER
#define SIMPLE_CHAT_SERVER

/*typedef struct
{
	char hostAlias[25];
	char ipAddress[16];
}connectedUser;*/

//int addUserToList(connectedUser* currentUsers, char *userHostAlias, char *userIpAddress, int userCount);

void showWelcomeMsg();
//void connectServer(unsigned int portNum);
//void printUserList(connectedUser* currentUsers, int userCount); //Take array of 'connectedUser' structures by reference
void printMessage(char *txtBuffer);

#endif

Any idea what the problem is?

p.s. I am using Microsoft Visual C++ Express
