extract cluster element names and values automatically

[Jamieg]

Dear Labview forum,

I would like to extract cluster element names and values automatically without prior knowledge of the cluster element size or contents.
I am able to extract the names but have some trouble with the values.  (see attached VI)

I wish to write each the cluster element name and value in a string, and then write the string to a new line in a file.

Regards,
Jamie

This can become arbitrarily complex, because a cluster can contain many types of data, even other clusters, arrays, typedefs, etc. So getting a "value" of an element is not as easy as you might think. There is a reason you get a variant. 😉

If all cluster elements are simple numerics you can use "variant to data" with the correct type. The attached shows a few possibilities. Modify as needed.

Hi,

It will be better that ur question is a little bit clear.

I think ur query is regarding how to get the cluster element values?

The vi below will be helpful for u

Parsing all the different data types to be able to write it to a file is a lot of work.

Luckily, the work has already been done - You can go to the OpenG site and download the Variant Configuration VIs which allow saving and loading clusters to text files. See here for an example.

Hi all,

altenbach's solution was what I was looking for.  The openG options I haven't yet explored.

Thanks for everyones' help.
