I'm new to VC++ and would like to know know how to link "wsock32.lib" within VC++. I'm trying to write a simple c++ server app and these are the error messages I'm getting. So how do I go about linking something in VC++?. Also is wsock32 the correct lib that I need?

推荐答案

您应与"ws2_32.lib"库链接.在项目设置中或通过pragma指令在源代码中指定它:

You should link with "ws2_32.lib" library. Specify it in project settings or in source code via pragma directive:

#pragma comment(lib, "ws2_32.lib")

添加:AFAIK Visual C ++ Express不包含Platform SDK，因此，如果在计算机上找不到库，则应下载并安装.

Addition: AFAIK Visual C++ Express does not includes Platform SDK, so if you can't find library on your computer you should download and install Platform SDK and add necessary folders in Visual Studio "VC++ Directories" property page.
