Re: How to get MAC address

I wrote the following code to get the MAC address of my Ethernet card but
it also returns a whole bunch of other interfaces. How can I just get the
address of my Ethernet card?

CString strMACAddress;
DWORD dwCount;
DWORD dwResult = GetNumberOfInterfaces(&dwCount);
MIB_IFROW ifEntry;
memset(&ifEntry, 0, sizeof(ifEntry));
for (DWORD i = 0; i < dwCount; i++)
{
 ifEntry.dwIndex = i + 1;
 dwResult = GetIfEntry(&ifEntry);
 if (dwResult == NO_ERROR)
 {
  if (ifEntry.dwOperStatus == MIB_IF_OPER_STATUS_OPERATIONAL &&
ifEntry.dwType == MIB_IF_TYPE_ETHERNET && ifEntry.dwPhysAddrLen != 0)
  {
   for (DWORD i = 0; i < ifEntry.dwPhysAddrLen; i++)
   {
    str.Format(_T("%.2X"), ifEntry.bPhysAddr[i]);
    strMACAddress += str;
    strMACAddress += _T('-');
   }
   strMACAddress.Delete(strMACAddress.GetLength() - 1);
   AfxMessageBox(strMACAddress, MB_OK, 0);
   strMACAddress.Empty();
  }
 }
}

Thanks
