get cluster element when changed

[El_Tipo]

Hello all,

Iam interested in knowning (after the user changes the value of a cluster) which element inside a cluster (any type of cluster) was changed.

so in an event structure case (clustername value change) i can get ctl ref, old val, new val.

On the other side I would like to get the either the refnum or name

I know old and new val will need to be variant (on my function) so that i can accomodate for any cluster. I have open G installed on my machine and have looked into the Open G LV data pallet as well as a Vcluster subpanel and havent been able to do this.

Here is an example of a given cluster

Here is another cluster example:

I have been able to do this in two different ways (always knowing before hand the cluster.

Method one:

Method two:

 Here is the skeleton of the function iam trying to build(testing the different possibilities):

So far I havent been successfull in this.

any help will be apreaciated.

This will get you the name of the 1st cluster item that is different from New Val

[Hooovahh]

Try this to get the old and new value along with the control name changed.

yes, but i still dont know which element inside the iner cluster changed.

example 1st cluster if i change say (electrical fault)

that array you sent will tell me that father cluster changed (only)

that i have been able to do.

thanks anyways

as soon as I changed your cluster with mine (with cluster inside cluster) the new/old value took a dump and lv started to complain. value change is good but i need name as well (at least)

thanks any ways hoovah.

Cluster in Cluster in Cluster etc...

You are going to have to recursively work down through levels of Clusters to get to the value.

A VI that you call recursively can walk down the cluster chain passing in the Old and new value.

There are posts about recursively walk down complex data control.

Yes, that is why you have to use the method that I posted.

Omar,

could you add a link of such recursively walk down examples (or posts)

Omar,

thanks for posting this.

Iam going to give it a try.
