IPHelp在Win98以后就被Windows支持，
是MS在WinSock上的再一层封装。
请下面的代码：
得到网卡列表：
//-----------------------------------------------------------------------
// GetAdapterLists
//-----------------------------------------------------------------------
BOOL CNetcfgDlg::GetAdapterLists(CComboBox &cmdAdapter)
{
bool bRet = false;
DWORD Err;
PIP_ADAPTER_INFO pAdapterInfo, pAdapt;
DWORD AdapterInfoSize;
CString csTmp;
UINT nIndex = 0;
cmdAdapter.Clear();
//
// Enumerate all of the adapter specific information using the IP_ADAPTER_INFO structure.
// Note: IP_ADAPTER_INFO contains a linked list of adapter entries.
//
AdapterInfoSize = 0;
if ((Err = GetAdaptersInfo(NULL, &AdapterInfoSize)) != 0)
{
if (Err != ERROR_BUFFER_OVERFLOW)
{
return false;
}
}
// Allocate memory from sizing information
if ((pAdapterInfo = (PIP_ADAPTER_INFO) GlobalAlloc(GPTR, AdapterInfoSize)) == NULL)
{
return false;
}
// Get actual adapter information
if ((Err = GetAdaptersInfo(pAdapterInfo, &AdapterInfoSize)) != 0)
{
return false;
}
pAdapt = pAdapterInfo;
//m_AdapterList.push_back(*pAdapt);
while (pAdapt)
{
csTmp.Format("%d\t%s",nIndex,pAdapt->Description);
cmdAdapter.AddString(csTmp);
//m_AdapterList.push_back(*pAdapt);
cmdAdapter.SetItemDataPtr(nIndex,pAdapt);
nIndex++;
pAdapt = pAdapt->Next;
}
}
显示单个网卡的信息：
csTmp.Format("适配器GUID:%s\n",pAdapt->AdapterName);
csAdpInfo += csTmp;
csTmp.Format("名称描述:%s\n",pAdapt->Description);
csAdpInfo += csTmp;
char buf[2];
CString csBuf = "";
for (UINT i=0; i<pAdapt->AddressLength; i++)
{
if (i == (pAdapt->AddressLength - 1))
sprintf(buf,"%.2X",(int)pAdapt->Address[i]);
else
sprintf(buf,"%.2X-",(int)pAdapt->Address[i]);
csBuf += buf;
}
csTmp.Format("网卡物理地址(MAC):%s\n",csBuf);
csAdpInfo += csTmp;
csTmp.Format("DHCP: %s\n", (pAdapt->DhcpEnabled ? "允许" : "不允许"));
csAdpInfo += csTmp;
pAddrStr = &(pAdapt->IpAddressList);
while(pAddrStr)
{
csTmp.Format("IP地址:%s\n",pAddrStr->IpAddress.String);
csAdpInfo += csTmp;
csTmp.Format("子网掩码:%s\n",pAddrStr->IpMask.String);
csAdpInfo += csTmp;
pAddrStr = pAddrStr->Next;
}
csTmp.Format("默认网关:%s\n",pAdapt->GatewayList.IpAddress.String);
csAdpInfo += csTmp;
csTmp.Format("DHCP服务器 :%s\n",pAdapt->DhcpServer.IpAddress.String);
csAdpInfo += csTmp;
csTmp.Format("主WINS服务器:%s\n",pAdapt->PrimaryWinsServer.IpAddress.String);
csAdpInfo += csTmp;
csTmp.Format("从WINS服务器:%s\n",pAdapt->SecondaryWinsServer.IpAddress.String);
csAdpInfo += csTmp;
SetDlgItemText(IDC_ADPINFO,csAdpInfo);
