Detecting internet connection.

[wyrd]

Is there a way to check if the user is connected to the internet?

 

[dynamic_sysop]

in a class module ( or below the End Class statement of your Form ) ...

Public Class _Win32

    Public Enum Connection As Integer
        Connected = 1
        DisConnected = 0
    End Enum

    Public Declare Function InternetGetConnectedState Lib "wininet.dll" (Optional ByRef lpdwFlags As Integer = 0, Optional ByVal dwReserved As Integer = 0) As Connection

End Class

to use from a button_click on your Form ...

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If _Win32.InternetGetConnectedState = _Win32.Connection.Connected Then
            MessageBox.Show("you are connected to the net")
        Else
            MessageBox.Show("you are NOT connected to the net")
        End If
    End Sub

So theres no way to do this using the .NET framework directly? Thanks.
