Hello everyone.

I am writing a user-mode program that manages NICs concently.
But I don’t know how to get NIC’s status(for example NIC is enabled
or not, NIC’s cable is connected or not)

Does anyone know the method?
Thanks.

Use WMI.

This is a script that will dump out lots of info on your attached NICs.

I think Availability and NetConnectionStatus under win32_networkadapter are
what you are looking for. You can also do it from C.

set svc = GetObject(“winmgmts:\root\cimv2”)
set NetAdapterConfigEnum = svc.ExecQuery(“select * from
win32_networkAdapterConfiguration where ipEnabled = true”, “WQL”, 32)

for each obj in NetAdapterConfigEnum
wscript.echo obj.GetObjectText_
strQuery = “associators of {” & obj.path_.relpath & “} where resultclass
= win32_networkadapter”
set NetAdapterEnum = svc.execQuery(strQuery, “WQL”, 32)
for each objAdapter in netadapterenum
wscript.echo objAdapter.GetObjectText_
next
next
