Check if user is Online

Description

The code checks if the User is online or not. If he's online it will prompt a MsgBox "You are connected to the net.") or it will Show: "You are NOT connected to the net.". You can also insert your code. This code is useful when your application uses the internet. So if the user is not connected the net, the program will simply unload.
