OpenLNS Programmer's Reference 629
CurrentOptions properties of network variable monitor points in temporary monitor sets are
not accessible, as temporary monitor sets are only used in a singe client session.
You can change the monitoring options a NvMonitorPoint will use for an active monitoring
session by writing to the NvMonitorOptions object accessed through the NvMonitorPoint
object’s CurrentOptions property. Changes made to the current options take effect for the
current session only, and are not stored persistently in memory.
Note that the NvMonitorOptions object contained within the NvOptions property of a
monitor set (or the DefaultOptions or CurrentOptions properties of a monitor point) is not
passed by reference. If you acquire an NvMonitorOptions object through any of these
properties and modify it, you must then explicitly assign the modified object back to the
source property for the changes to take effect.
The following table summarizes the NvMonitorOptions object.
