Detecting Internet Connection

How can I check if there is an active internet connection? It needs to work on a LAN going through a proxy server...

I've tried
http://www.vb-world.net/tips/tip27.html

Which doesn't work, but one of the replies mentioned using


Private Declare Function InternetGetConnectedStateEx Lib "wininet.dll" Alias "InternetGetConnectedStateExA" (ByRef lpdwFlags As Long, ByVal lpszConnectionName As String, ByVal dwNameLen As Long, ByVal dwReserved As Long) As Long


but I have no idea what values to provide for all the arguments this function requires...

Help!!
