Syncronizing index of to array controls

[Anders Björk]

I have been trying some hour to to syncronize the index of two array controls by use of the property nodes, is it possible to get that working?

I don't fully understand what you want.

I think you mean that if one of the array controls it's index changes the other one follows?

And most likely this should be event driven.

What kind of code do you have?

Yes thats what I meant.

I had a simple while loop with two array controls, two property nodes, a time delay and stop button. For testing, tested several properties by read and write.

Could you post an attachment that illustrates what you've tried (either VI or screenshot of the Block Diagram)? Sometimes a picture really helps define what you're trying to accomplish.

If you're just trying to get an array to change its index that is currently appearing at the upper left corner of the front panel array control, use the "Index Values" property.

Thanks very much for your help! I used the same properties before it didn't work, I was quite puzzled why :/

Hmm.. Not sure why that wouldn't work (works fine for me). On a side note, wiring through block diagram objects like that (through Array2's property node to Array3's) violates the left-to-right data flow, and you can't be 100% certain where the connection points are without moving Array2's property node out of the way. Of course, I'm being slightly hypocritical on style guidelines since I didn't wire up the error nodes in my example.

Is it working for you now, or are you still having trouble?

Example (LV8.0.1)

It is working fine, tomorrow I will try to implement that in an application. I will take note of your suggestion when wiring it up tomorrow.
