有谁知道如何遍历局域网内的所有机器的IP地址.

另外问一下有没有相关的网站对其有介绍?

You can use this code to retrieve the host information in a network and also get the IP address of each pc.

大家已经说得很清楚了。

你可以安装一个叫做CommView的软件
其最新版本功能很强大的

BOOL Enumerate()
{
//get this machines host name
char szHostname[256];
WSADATA wsaData;
WORD wVersionRequested;
if ( WSAStartup( wVersionRequested, &wsaData ) == 0 )
{
if (gethostname(szHostname, sizeof(szHostname)))
{
TRACE(_T("Failed in call to gethostname, WSAGetLastError returns %d\n"), WSAGetLastError());
return FALSE;
}

//get host information from the host name
HOSTENT* pHostEnt = gethostbyname(szHostname);
if (pHostEnt == NULL)
{
TRACE(_T("Failed in call to gethostbyname, WSAGetLastError returns %d\n"), WSAGetLastError());
return FALSE;
}

//check the length of the IP adress
if (pHostEnt->h_length != 4)
{
TRACE(_T("IP address returned is not 32 bits !!\n"));
return FALSE;
}

//call the virtual callback function in a loop
int nAdapter = 0;
BOOL bContinue = TRUE;
while (pHostEnt->h_addr_list[nAdapter] && bContinue)
{
in_addr address;
CopyMemory(&address.S_un.S_addr, pHostEnt->h_addr_list[nAdapter], pHostEnt->h_length);
bContinue = EnumCallbackFunction(nAdapter, address);
nAdapter++;
}
WSACleanup( );
return TRUE;
}
}

BOOL EnumCallbackFunction(int nAdapter, const in_addr& address)
{
// printf("%0d %d.%d.%d.%d\n", nAdapter, address.S_un.S_un_b.s_b1,
// address.S_un.S_un_b.s_b2, address.S_un.S_un_b.s_b3, address.S_un.S_un_b.s_b4);
CString strAddr;
strAddr.Format("%0d %d.%d.%d.%d\n", nAdapter, address.S_un.S_un_b.s_b1,
address.S_un.S_un_b.s_b2, address.S_un.S_un_b.s_b3, address.S_un.S_un_b.s_b4);
::AfxMessageBox(strAddr);
return TRUE;
}
