NvHubs

Summary

Returns a collection containing all network variable hubs for

which the network variable is a target, including the network

variable if it is the hub for a connection. In conjunction with

the

NVTargets

property, this property enables you to manage

complex network connections involving multiple hubs and

sets of targets.
When a new hub is added, it will not neccessarily be added to

the end of the list of hubs; therefore, you should update the

cached copy of the complete hub list when you add or delete a

hub.

Availability
