用VC编程出现的连接错误—— 一个弱智的问题

[wisename]

我是个菜鸟级的菜鸟
刚买了本比较旧的书 书中有这样的程序，我在VC6.0下编译通过，但不能执行出现连接错误
helo.obj : error LNK2001: unresolved external symbol __imp__closesocket@4
helo.obj : error LNK2001: unresolved external symbol __imp__send@16
.........
Debug/tcpip.exe : fatal error LNK1120: 8 unresolved externals
Error executing link.exe.
我不知如何解决，那位高手给我一个建议，万分感谢！！！！

我建工程时选的是WIn32 Console Application
以下是hello.cpp
#include < winsock.h>
#include < iostream.h>

class ENoSocket{};
class EBadSocket{};
class EBadClient{};

class CWin32TCPEnv

{
public :
CWin32TCPEnv(void)
{
const WORD wMinVer=0x0101;
WSADATA wsaData;
if(0!=::WSAStartup (wMinVer,& wsaData))
throw ENoSocket();
}
~CWin32TCPEnv(void)
{
if(0!=::WSACleanup ())
throw ENoSocket();
}
};


int main(void)
{

SOCKET s,sc;

CWin32TCPEnv Environment;

try
{
if(INVALID_SOCKET==(s=::socket (PF_INET,SOCK_STREAM,0)))
throw ENoSocket();

SOCKADDR_IN sa;
sa.sin_family=AF_INET;
sa.sin_addr.S_un.S_addr =INADDR_ANY;

sa.sin_port=htons(2058);

if(SOCKET_ERROR==::listen(s,5))
throw EBadSocket();

cout< < "Ready to server my first client.Please connect..."< < endl;

if(INVALID_SOCKET==(sc=::accept(s,NULL,NULL)))
throw EBadSocket();

const char szHello[]="Hello,TCP/IP!\r\n";

if (SOCKET_ERROR==::send (sc,szHello,sizeof(szHello),0))
throw EBadClient();

cout< < "Anotherclient srver!"< < endl;

::closesocket (sc);
::closesocket (s);
}
catch(ENoSocket& )
{
cerr< < "ERR:TCP/IPstack error"< < endl;
}

catch (EBadSocket& )
{
cerr< < "ERR:Server socket is bad."< < endl;

::closesocket(s);
}
catch(EBadClient& )
{
cerr< < "ERR:Client went Bad."< < endl;

::closesocket (sc);
::closesocket (s);

}
return 0;
}

将Ws2_32.lib加入，方法是：
Project->Settings->line->object/library modules
在输入框中输入Ws2_32.lib

这是你的编译设置里没有包含相应的库文件(.lib)
看下面：
Header: Declared in Winsock2.h.
Library: Use Ws2_32.lib.
把这个库文件加入再试试！
