Examples
This example reports whether or not the server can be pinged by determining whether the Ping method returns True.
If My.Computer.Network.Ping("198.01.01.01") Then
MsgBox("Server pinged successfully.")
Else
MsgBox("Ping request timed out.")
End If
Replace "198.01.01.01" with the IP address, URL, or computer name of the server to ping.
This example reports whether or not the server can be pinged by determining whether the Ping method returned True and specifies a timeout interval of 1000 milliseconds.
If My.Computer.Network.Ping("www.cohowinery.com",1000) Then
MsgBox("Server pinged successfully.")
Else
MsgBox("Ping request timed out.")
End If
Replace "www.cohowinery.com" with the IP address, URL, or computer name of the server to ping.
Remarks
The Ping method is not a fail-safe method for determining the availability of a remote computer: the ping port on the target computer may be turned off or the ping request may be blocked by a firewall or router.
The address passed to the Ping method must be DNS resolvable and cannot be preceded by "http://".
