Internet connection

[Krzysztof Kazmierczak]

Hi All!

How i can check if is there an internet connection
available? When i use API functions
(InternetAttemp tConnect, InternetCheckCo nnection,
InternetGetConn ectedStateEx) i sometimes have diferent
results (when there's no cable, functions says that i'm
connected).
Is there any other method instead of trying to catch the
exception while proceding WebRequest and WebResponse when
the network cable is unplugged?

Thank you very much for any help!
Kind regards
Krzysztof Kazmierczak

Hi Krzysztof,

You can use the WMI class MSNdis_MediaCon nectStatus in the root\wmi
namespace. The NdisMediaConnec tStatus property gives the connection status
of the NIC on the network. Please refer to the following thread for some
code snippet:

Hope this helps.
