Here's a simple version that might help.
Option Explicit Option Private Module Private Declare Function InternetGetConnectedState Lib "wininet" _ (ByRef dwFlags As Long, _ ByVal dwReserved As Long) As Long Private Declare Function InternetCheckConnection Lib "wininet.dll" _ Alias "InternetCheckConnectionA" (ByVal sUrl As String, _ ByVal lFlags As Long, ByVal lReserved As Long) As Long Public Function IsNetConnected() As Boolean Dim lReturn As Long 'you might want to put a get out clause in here that returns true 'if the test is taking place behind a proxy server, which sometimes doesn't work 'e.g. this checks a registry setting for an option to disable the function 'you can omit the next 4 lines if this is beyond your needs If CBool(GetSetting("ProgName", "Settings", "DisableNetDetect", "FALSE")) Then IsNetConnected = True Exit Function End If IsNetConnected = InternetGetConnectedState(lReturn, 0) If IsNetConnected = False Then _ IsNetConnected = InternetCheckConnection("http://www.yahoo.com", 1, 0) If IsNetConnected = False Then _ MsgBox "You do not appear to have an active internet connection at this time" _ & vbcrlf & "Please connect to the internet then retry this command", _ vbOKOnly + vbInformation End Function Robin Hammond www.enhanceddatasystems.com wrote in message ups.com...
