The following piece of code uses the My.Computer.Network.IsAvailable property to determine whether or not the computer is connected to a network. This network could be the Internet or a local network; for as long as the computer is connected to one such network, the response retrieved will be positive.

Dim networkAvailable As Boolean = My.Computer.Network.IsAvailable

If networkAvailable Then
    MsgBox("The network is available")
Else
    MsgBox("The network is unavailable")
End If

This Visual Basic (VB.NET) code snippet is used to check if a network connection is available and then display a message box indicating the network status:

1. Declaring and Initializing networkAvailable:
   • Dim networkAvailable As Boolean = My.Computer.Network.IsAvailable
   • This line declares a Boolean variable networkAvailable and initializes it with the result of My.Computer.Network.IsAvailable. This property returns True if a network connection is available, and False otherwise.
2. Conditional Check and Message Box Display:
   • The If...Else statement checks the value of networkAvailable.
   • If networkAvailable is True (meaning the network is available), it displays a message box with the text “The network is available”.
   • If networkAvailable is False, it shows a different message box stating “The network is unavailable”.

This code is typically used in applications that need to verify network availability before performing network-dependent operations.
