To determine which network was attached or detached, the script needs to call
GetString() on the roNetworkAttached/roNetworkDetached event object. These methods provide an index of the network interface that was attached or detached.
Reconfiguring a network interface using roNetworkConfiguration may cause it to detach and attach again.
SetPort(a As Object)
Posts messages of type roNetworkAttached/roNetworkDetached to the attached message port.
SetUserData(user_data As Object)
Sets the user data that will be returned when events are raised.
GetUserData() As Object
Returns the user data that has previously been set via
SetUserData(). It will return Invalid if no data has been set.
