Syntax

Finding out whether an Internet connection is enabled Hide the details

<Result> = InternetConnected()

<Result>: Boolean

True if an Internet connection is enabled on the current computer,
False otherwise.

Versions 19 and later

Asking for a notification when the status of the Internet connection changes Hide the details

<Result> = InternetConnected([<Procedure name>])

<Result>: Boolean

True if the procedure was associated with InternetConnected,
False otherwise.

<Procedure name>: Character string (with or without quotes)

WLangage procedure ("callback" procedure) called when the status of Internet connection changes.
This procedure has the following format:

PROCEDURE <Procedure name>(<Status>)

<Status> is an integer constant corresponding to the new status of the Internet connection.
It can take the following values:
networkDisconnected The network is disconnected or inaccessible.
networkEthernet The Internet connection is performed by Ethernet.
networkMobile The Internet connection is performed in mobile mode: edge, 2G, 3G, 4G, ...
networkWifi The Internet connection is performed by Wi-Fi.

If <Procedure Name> corresponds to an empty string (""), the WLanguage procedure that was defined beforehand will not be called anymore.

Remarks

Firewall

InternetConnected uses a ping request in order to check the access to Internet. Therefore, the ping must be allowed by the security parameters of the network in order for the result of the function to be pertinent.

Remark: The ping is performed on the Google DNS (6 seconds, 1 attempt). The equivalent code is:

Ping("8.8.8.8", 6000, 1)
