This snippet will check if your computer is currently logged onto the internet in VB.NET. This is especially useful if you are using winsock

Module CheckNetwork

    Sub main()

        If My.Computer.Network.IsAvailable = True Then

            System.Console.WriteLine("Computer is connected.")

        Else

            System.Console.WriteLine("Computer is not connected.")

        End If

        System.Console.ReadLine()

    End Sub

End Module

VisualBasic is my current AS level course language, which i get on with quite well, unlike my rather stupidsounding comments on here! i have somewhat a reluctance to try things out for myself -- mainly because Visual Studio takes such a dam long time too load! haha

Thanks :)

If you're into scripting I would suggest F# .. It basically gives you all the benefits of a compiled language and the agile/cool features of a scripting language.. It's pretty much the next big thing in Microsoft and considered to be the language of the future :)

Okay, i sort of see. I'm fairly new to this -- although been using various computer languages they've been scripts rather than compiled programs.

The imports keyword is only used to create a shorthand notation for ease of use of the underlying namespace classes. When converted to MSIL the hardcoded IL written is actually System.Console.WriteLine ...

You are actually "importing" the functionality of an assembly when you add it to your project reference's file. P.S you can only use Imports when an external assembly is referenced.

so by using system.console, or another cmd like that you are "temporarily" importing those class libraries?

Yeah, System.Console is unneeded. To go even further you can use "Imports System.Console" and simply use "WriteLine" and "ReadLine".

This snippet does not detect if your computer is connected to the internet. It actually determines if your computer is connected to a network (like LAN etc) :)

Why System.Console.etc, why not just Console.WriteLine? I'm fairly new to .net :)
