How do I count Nic cards?

NTDEV
1

In NT I can count the keys in :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards

I don’t see anything similar in 9x. The closest I can see is in
HKLM\Enum\PCI then enuming thru the entries and looking for a subkey of
class with a value of “NET”. Observation seems to indicate that only NIC
cards have this setting, although I have not seen this verified thru a
“reputable” doc anywhere…is there a better way to do this?

Thanks,
Adam

Hi,

In fact I was just looking into this thing recently for all the OS’s.

I believe you can find the cards under HKEY_LOCAL_MACHINE\System\Services\Class\Net in win98.

You should avoid reading the registry as much as possible. There are several
ways to get this information.

  1. You can use INetConnectionManager interface (presuming you know COM) and
    enumerate all LAN devices.
  2. You can use GetAdaptersInfo.
  3. You can use SetupDi functions and enumerate GUID_NDIS_LAN_CLASS devices
    and filter out WAN devices.

I don’t know which one is compatible across all platforms. My guess would be
2).

I really liked option 2, and will keep it in mind for the future.
Unfortunately it doesn’t support NT or 95. Option 3 requires a driver which
is out of the question. Option 1 has me curious, searching my MSDN I find
no hits on ‘INetConnectionManager’, so I checked the 2K and 98 DDK’s and the
msdn online and still found no hits. What/where is this thing?
