各位大侠，请问如何获取局域网内的各计算机的IP地址（vc下）帮忙了

[dolphi]

在子网范围内全部Ping一下，通的IP就记下来。这办法挺笨的。

[wjy88]

struct hostent *host;
struct in_addr *ptr; // To retrieve the IP Address

DWORD dwScope = RESOURCE_CONTEXT;
NETRESOURCE *NetResource = NULL;
HANDLE hEnum;
WNetOpenEnum(dwScope, NULL, NULL, NULL, &hEnum);

WSADATA wsaData;
WSAStartup(MAKEWORD(1,1),&wsaData);

if (hEnum)
{
DWORD Count = 0xFFFFFFFF;
DWORD BufferSize = 2048;
LPVOID Buffer = new char[2048];
WNetEnumResource(hEnum, &Count, Buffer, &BufferSize);
NetResource = (NETRESOURCE*)Buffer;
char szHostName[200];
for (unsigned int i = 0; i < BufferSize/sizeof(NETRESOURCE); i++, NetResource++)
{
if (NetResource->dwUsage == RESOURCEUSAGE_CONTAINER && NetResource->dwType == RESOURCETYPE_ANY)
{
if (NetResource->lpRemoteName)
{
CString strFullName = NetResource->lpRemoteName;
char buf[512];
if ( 0 == strFullName.Left(2).Compare("\\\\"))
strFullName = strFullName.Right(strFullName.GetLength()-2);
gethostname(szHostName, strlen( szHostName ));
host = gethostbyname(strFullName);
if (!host) continue;
ptr = (struct in_addr *) host->h_addr_list[0];
sprintf(buf, "%d.%d.%d.%d", ptr->S_un.S_un_b.s_b1,
ptr->S_un.S_un_b.s_b2, ptr->S_un.S_un_b.s_b3, ptr->S_un.S_un_b.s_b4);
}
}
}
delete Buffer;
WNetCloseEnum(hEnum);
}
