请教高手，socket问题

[williams_h]

程序出错部分代码如下：(vc60)

#include <winsock.h>
char szHostName[128];
CString str;

if(gethostname(szHostName,128)==0)
{
// Get host adresses
struct hostent * pHost;
int i;

pHost=gethostbyname(szHostName);

for(i=0;pHost!=NULL&&pHost->h_addr_list[i]!=NULL; i++)
{
int j;

for(j =0; j<pHost->h_length;j++)
{
CString addr;

if(j>0)
str+=".";

addr.Format("%u", (unsigned int)((unsigned
char*)pHost->h_addr_list[i])[j]);
str+=addr;
}
// str now contains one local IP address - do whatever you want to do with it (probably add it to a list)
}
}
出错代码为：
Linking...
showipView.obj : error LNK2001: unresolved external symbol _gethostbyname@4
showipView.obj : error LNK2001: unresolved external symbol _gethostname@8
Debug/showip.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

可否告知错在那里，如何修改,不胜感谢！！！！！！！！！！！！！！！

gethostname()函数需要：
Version: Requires Windows Sockets 1.1 or later.
Windows CE: Requires version 1.0 or later.
Header: Declared in winsock2.h.
Import Library: Use ws2_32.lib.

工程设置中，alt + F7,选 Link ,在 lib中添加ws2_32.lib

这是低手也应该会的问题
