Hello,

I want to send SMS through my application, before which i want to check whether the computer has live internet connection. Is there a fool-proof way to determine it?

推荐答案

My.Computer .Network.IsAvailable 可以确定计算机当前是否已在网络中连接.

还可以ping一些网站以检查互联网连接

My.Computer.Network.IsAvailable  can determine whether computer is currently connected in network or not.

You can also ping some website to check internet connection

    If My.Computer.Network.Ping("www.google.com") = True Then
            MsgBox("Internet available")
        Else
            MsgBox("Internet unavailable")
        End If
