Value (Signaling) Property

Short Name: Val(Sgnl)

Installed With: Base Package

Class: VISAResourceName Properties

Sets the value of the control and generates a Value Change event.

This property updates the value of an object similar to the Value property. However, Value (Signaling) also causes LabVIEW to generate an event as if the user had interactively changed the value of the object. National Instruments recommends you use this property only when you rely on LabVIEW generating an event in response to the programmatic value change.
