I've been searching around the Internet for ages now.
Never did I saw a working code to check and see if the
End-User has a valid Internet Connection.

Checking Registry, WinInet.dll, Pinging, URL Exists,
DSN Resolves, API, and even useless Winsock Control.

None of these things really worked.
People these days are connected to all types of devices.

Modem, LAN, Proxy, DSL, T1, T2, T3, DS3, OC3
All kinds of speed.

How can Microsoft do this? and not make it public information
on how to determine if a User is Connected?

Anyone who got a REAL WORKING API CALL, DEMO, OR EXAMPLE PROJECT? If you do please give me the URL and I can take
it from there.
