LV 8.5.X: Enum Constant, Number of Elements

[Udo]

Hello,

I want to determine the number of elements of an enum constant, is
that possible at all?

Thanks and greetings,
Udo

THat could be a little tricky since you don't have properties. I'd first try to use a flatten to string (configure for the LV 7 version) and then parse the type descriptor.

Anyone have any better ideas?

Number of Items property node?

Oh. Just noticed that he said Constant.

That is for me interesting too. I use Enum-Typedef to enumerate my Tasks (parallel Loops) and want to create one queue per Task. So I take my enum-CONTROL and than the property of them to get all strings from the list to give my queues the names from the list. But I would prefer to use enum constant for this. Is it possible?

Thanks

There is an OpenG VI to get the possible string values of an Enum. The length of the returned array is the number of possible values.

Thank you, my question is answered. I can use flatten 7X and then format into string for my issue.

Ben,

What is the thing behind indexing 2?

I mean, how will I have to know that when I index 2, I ll get the Enum constant's item count...

That is buried inside the LabVIEW data-type definition:

---

Enumerated 8-Bit Integer

In the following example of an enumerated 8-bit integer for the items am, fm, and fm stereo, each group of characters represents a 16-bit word. The space enclosed in quotation marks (" ") represents an ASCII space.

0016 0015 0003 02a m02 fm 09f m" " st er eo

0016 indicates 22 bytes total. 0015 indicates an enumerated 8-bit integer. 0003 indicates there are three items.

Here's the VI I was talking about.
