Answer 1

Private Declare Function Ping Lib "iphlpapi" _
Alias "#65" (ByVal pInternetProtocol As Long, pNumberOfCalls As Long, _
ByVal pMaxNumberOfCalls As Long, lTime As Long) As Long
Private Declare Function ConvertStringToIP Lib "wsock32" _
Alias "#10" (ByVal stoip As String) As Long

Function MyPing(sIPAddr As String) As Boolean
Dim IP As Long, pNumCalls As Long, lTime As Long
IP = ConvertStringToIP(sIPAddr)
MyPing = (Ping(IP, pNumCalls, 15, lTime) = 1): End Function

'Chamando a Função'
Private Sub Form_Load()
Dim Result As Boolean: Result = MyPing("200.158.24.129")
If Result = True Then
MsgBox "OK"
Else
MsgBox "Não Respondeu": End If
End Sub 

Answer 2

It is that this solution is called API and depends on specific Dlls. Another solution is to use the INET component and encode like this:

Wresposta = Inet1.OpenURL("http://www.brasil.gov.br/")
if Wresposta = "" then
   msgbox("Fora da NET")
endif
