The WebRequest class throws a WebException when errors occur while accessing
an Internet resource, so just try to connect and trap any erro that arises.

just call above ftn which returns true or false

Private Function IsConnectionAvailable() As Boolean
'Call url
Dim url As New System.Uri("http://www.google.com/")
'Request for request
Dim req As System.Net.WebRequest
req = System.Net.WebRequest.Create(url)
Dim resp As System.Net.WebResponse
resp = req.GetResponse()
req = Nothing
Return True
Catch ex As Exception
req = Nothing
Return False
End Try
End Function
