Read/Write Read only.
Added to API Depends on the object used to access the property. Generally,
this property exists for an object as soon as the object is
added to the API.
_NewEnum
Summary Enables you to iterate over the objects in a collection using
For Each ... Next statements.
•
If you are developing your OpenLNS app in Visual C++,
you can browse a collection to find a particular item by
using the _NewEnum property. See the IEnumVARIANT
interface for details.
• If you are developing your OpenLNS app in Visual Basic,
you do not need to use the _NewEnum property because
it is automatically used in the implementation of For
Each ... Next statements.
• If you are developing your OpenLNS app in C#, you do
not need to use the _NewEnum property explicitly
because it is automatically used in the implemention of
foreach statements.
Availability Local, full, and lightweight clients.
Syntax retrievedObject = coll Object._NewEnum
Element Description

Data Type Object.

Added to API OpenLNS.
NvMonitorOptions
The NvMonitorOptions object contains a set of monitoring options that can be applied to the
network variable monitor points that LNS is monitoring. Depending on how this object is
accessed, writing to it may affect the monitoring options used for an entire monitor set, or for
an individual network variable monitor point.
The
NvMonitorOptions object accessed through a MonitorSet object's NvOptions property
contains the defaults options for the monitor set. These are the default options applied to all
NvMonitorPoint objects as they are added to the monitor set.
You can change the defaults an individual NvMonitorPoint uses by writing to the
NvMonitorOptions object accessed through the DefaultOptions property of that
NvMonitorPoint object. This object contains the default options that will be used each time
the monitor set containing that particular NvMonitorPoint object is opened. Note that this
only applies to network variable monitor points in permanent monitor sets. The
