问关于WSAStartup(WINSOCK_VERSION,&wsaData）的参数

stone_w8 2000-09-06 10:46:00

用WSAStartup(/*WINSOCK_VERSION*/WINSOCK_VERSION,&wsaData)提示错误：
error C2065: 'WINSOCK_VERSION' : undeclared identifier

可能是少一个包含文件，我想
该怎么对付

如果是 Winsock 1.1 则

#define WINSOCK_VERSION MAKEWORD(2,0)

改为

#define WINSOCK_VERSION MAKEWORD(1,1)

//winsock 2.0
#define WINSOCK_VERSION MAKEWORD(2,0)

VC/MFC社区版块或许是CSDN最“古老”的版块了，记忆之中，与CSDN的年龄几乎差不多。随着时间的推移，MFC技术渐渐的偏离了开发主流，若干年之后的今天，当我们面对着微软的这个经典之笔，内心充满着敬意，那些曾经的记忆，可以说代表着二十年前曾经的辉煌……
向经典致敬，或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天，我们期待着MFC技术能够恢复其曾经的辉煌，或许这个期待会永远成为一种“梦想”，或许一切皆有可能……
我们希望这个版块可以很好的适配Web时代，期待更好的互联网技术能够使得MFC技术框架得以重现活力，……
