reference of a control from the reference of a vi

[RavensFan]

Use the property node Array Element.  You can cast that to a more specific type of control if needed.

Try this (Test.vi).

This still does not tell me how to obtain references to the individual elements of an array.

The only way that I have ever read about to get at elements in an array is demonstrated in the Nugget I linked above. Asie from that example, I know of no other way to get at indiviual elements inside an array.

In the "Get All Control ReferencesV4.vi" you have:

The only thing that is of meaning for "individual elements of the array" is the value of a particular element.  In that case you can use the Value property node of the array and then index array to get the value of your element of interest.  All other properties of the elements of the array must be the same, in which case you use the method I showed you in reply #11 to get the properties of the elements.

I need the reference to the individual elements because I'm using an array of clusters and need to access nonvalue properties of individual controls inside of the clusters.

provided you are not trying to set the properties of different elements of the array to different settings, the code shown in that Nugget will help show you how to do it.

Yes that Nugget is not easy to understand but what what you have been asking is not easy and prior to that Nugget was not commonly concidered possible.

No I don't get paid my how many views of the Nugget i get.

But this only returns the reference to the array. I need access to individual elements.

"provided you are not trying to set the properties of different elements of the array to different settings"

I am trying to.

Elements of an array can differ ONLY in their value. The properties of all elements in an array MUST be the same.

if you really need to do that, use a cluster where you can have different properties.
