initializing menu ring elements in array

[lmd2]

I know that it is possible to initialize the elements of a menu ring using the property STRINGS[]. I have an array of 16 menu rings for labeling DAQ channels, and need to initialize the rings based of the set of available sensors (ie some sensors are retired, or out for calibration, new ones purchased). Is there a way to expose this property for an array of menu rings?

thanx

Hi lmd2,

you want to have different strings for those rings? That's not possible, all elements in an array have to have the same properties!
Their only difference is the value...

Solution: define the ring with all needed values/strings and just set the values of the rings in the array!

I understand that all the array elements will be identical; but my point is that this week they need to be A, B, C; and next week A, B, D
I don't understand your solution; for a single ring yes, use STRINGS[] - but I can not find this property for a ring that is an array element.

Hi Lawrence,

one way to get a property node is to right-click the array element on the front panel -> create property node. That should always work...

This seems to work, but I don't know how it would behave in a compiled application.

Use a property node to get the Array Element.Reference.

From the front panel, select the ring inside the array and Create Reference (switches to BD and places a constant)

Use 'To More Specific Class' to convert the array Element Reference to a menu ring ref using the constant from above.

Set the strings Property.

been using LabVIEW for 13 years and never accessed an array elements properties from the front panel, very cool
thanx
