controls[]

[id]

I am simply trying to use the main menu vi  front panel controls property as a reference to pass to a subVI which shal execute a motion control move using an event structure.  When in the subVI, I want to determine which control has changed on the main menu front panel so that I can code it in the event structure. 

I know the front panel controls array is in the tab order on the main menu but how do I extract which button has been pushed so that I can do a changevalue event registration on the control?  It appears that I have to register each of these buttons as individual events rather than the entire menu cluster with post processing in the event structure case.  What am I doing wrong?

Why don't you pass references to just those controls that you are interested in? Alternately, you could put all the controls into a single cluster and pass a reference to that cluster to the subvi. You would then create a value change event on the cluster and compare the NewVal and OldVal event data to determine which control in the cluster changed.
