The goal ist to create a routine or methode, that changes the ´string list in a cluster'. There would be multiple clusters to control a Multipexer with 80 Channels, so I dont want to generate 80 x 8 references to each Ring. Is there a way to do it?
If you have 80 separate clusters and want to change the strings of a ring control in each of them without using reference constants get the references programatically...
In the attached example I have three clusters. If you change the strings array and run the VI you'll see that the options ring in all clusters are changed. In this example I identify all the clusters by searching for clusters that has a name containing cluster, that's just an example...you could have an array with the names of the clusters you want to control...or some other way of identifying them.
Forgot to close the VI reference at the end of the code by the way, if you use a similar technique remember to close *all* opened references, otherwise you can easily get a memory leak in your application. It's not always easy to know when clsoing will be necessary or whether it will be a NULL operation...especially since it has been changed between different LabVIEW versions, but it's a good idea to do the close just as a rule of thumb.
