How can I determine the representation of a numeric control from a reference?

[johnsold]

Property nodes report Class ID and Class Name but those are the same for U8, I32, DBL,... 18 and Digital, respectively.

Maybe there is a better way to do what I am trying to do. I have a cluster with mostly numeric controls, mixed U8, U16, U32, and SGL. I want to write the values and labels to a config file. I was going to select which type of Write to Config File VI to use based on the datatype. I take a reference to the cluster, get the array of Controls[] references and feed that to a for loop. But I cannot seem to find a way to distinguish the numeric types from each other. The Data Range property can be used to identify the integer types (as long as it has not been modified), but I cannot find a property for the representation itself.

Thanks,

Hi Lynn,

This LAVA post covers your question (scripting used), but what about the OpenG Variant Config tools?
They do exactly what you want!

Ton,

Thanks,

That got me on the right path.

If you are using LV8.0 or later, there are a group of datatype VIs in vi.lib which also do the same thing.  Be aware that they are not "finished" so the API and location may change from LV version to LV version.  Since they are used internally, changes should be minimal.  You can find them at <vi.lib>/Utility/VariantDataType.

I saw a reference to these in another thread where you posted.

Thanks,
