Hi All,
I'm having trouble getting an event structure to register value changes on boolean and enumerated control types when their values are changed using an invoke node called from a separate VI rather than via user interaction in the same VI.
I have a control VI which the user interacts with... and a display VI linked via a VI server reference which contains a video playback, but normally no user interface.
When the user changes a boolean in the Control VI, the boolean value changes in the Control VI and this change is reflected in the Display VI. However, the Value Change event for this boolean IS NOT registered within the Display VI. If you manually change the value in the Display VI, after making the control visible, the Value Change event for that boolean IS registered.
It seems that Value Change event cannot be triggered using an invoke node to operate on a control... Has anyone run into this and discovered any work arounds?
Thanks,
Andrew Brown

Are you using Value Change property node or Value Change (Signalling) property node. The latter is designed so that Event structures are triggered.

Thanks a lot.
Works Perfectly Now!
