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:
- Declaring and Initializing
Dim networkAvailable As Boolean = My.Computer.Network.IsAvailable
- This line declares a Boolean variable
networkAvailableand initializes it with the result of
My.Computer.Network.IsAvailable. This property returns
Trueif a network connection is available, and
- Conditional Check and Message Box Display:
If...Elsestatement checks the value of
True(meaning the network is available), it displays a message box with the text “The network is available”.
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.
