Determine if a Network (LAN) is Present

In AutoPlay Media Studio, to determine if a user is connected to a LAN:

1. Insert the following code into any event in your application:

lan = System.GetLANInfo();
lan_exist = true;
for j in lan do
    if lan[j] == "Unknown" then
        lan_exist = false;
    end
end

if lan_exist then
    Dialog.Message("", "You are connected to a LAN");
else
    Dialog.Message("", "You are not connected to a LAN");
end

Note:  This example works in Windows 98 First Edition, Windows 98 Second Edition, Windows 2000, and Windows XP.  Windows 95 and Windows NT do not fit this model.  To detect a LAN connection in all operating systems, first detect the user's OS, and the launch an appropriate detection script.
