socket编程声明就出错，有劳定位下，辛苦了

[zhaolixin007]

#include "winsock2.h"//add by zhaolixin here
#pragma comment(lib,"ws2_32.lib")//add by zhaolixin here

在函数::InitInstance()中填写的语句如下
WSADATA wsd;//add by zhaolixin here
WSAStartup(MAKEWORD(2,2),&wsd);//add by zhaolixin end

提示如下错误：
Compiling...
ZQQ.cpp
F:\DD\ZQQ\ZQQ.cpp(47) : error C2065: 'WSADATA' : undeclared identifier
F:\DD\ZQQ\ZQQ.cpp(47) : error C2146: syntax error : missing ';' before identifier 'wsd'
F:\DD\ZQQ\ZQQ.cpp(47) : error C2065: 'wsd' : undeclared identifier
F:\DD\ZQQ\ZQQ.cpp(48) : error C2065: 'WSAStartup' : undeclared identifier
Error executing cl.exe.

ZQQ.exe - 4 error(s), 0 warning(s)

#include <winsock2.h>

#pragram comment(lib, "Ws2_32.lib")

加在 stdafx.h 最后面

[Shrek_MyCpp]

在stdafx.h中，加入#include <afxsock.h>

在cpp文件中，调用AfxOleInit()

[Shrek_MyCpp]

然后，就可以直接使用socket的接口函数了。

#include "winsock2.h"//add by zhaolixin here
#pragma comment(lib,"ws2_32.lib")//add by zhaolixin here
---------------------------------------------------------
这个你加在哪里？？？

检查一下
如果工程里存在afxsock.h的话
就把winsock2.h和另一个（我不记得名字了）有关socket的头文件去掉
