how can i get from enum items name.

[M_Peeker]

Hi,

An enum contains the names in its type definition, and this can not be changed in run time.

Cut from the help of the Strings[] property: "If the string is an enumerated type control, you cannot write this property when the VI is running"

If you wish to edit the strings programatically I believe using a text or menu ring is the way to go.

Hello Siva,

To add to the discussion, you may find the following KnowledgeBase article useful:

What is the Difference Between a Text Ring and an Enum?

As it has been pointed out, you can't change the items in an enum at runtime. You can however enable and disable (gray-out) items at runtime. Perhaps that helps.

openg.org no longer exists. Support is now through lavag.org. See OpenG's Get Strings from Enum__ogtk.vi

Hi dwb,

thanks for bringing back this old thread!

What's wrong with the "Strings[]" property of the enum? No need to download any library of VIs…

Not sure if it is currently a complication but...

In RT (LV 6.1) the FP control properties do not work. Drove me nuts that I could step through the code and see it work but when run as an exe, no-workie.

I was really just updating information from another persons post because the URL and VI name have changed, but, if you want a list of the strings (or just the number of them) from a Block Diagram enum constant, that library function does it. I didn't want to create a Front Panel object just to be able to access the properties.

Or the 'Type def to strings' from the Variant function panel, no property nodes needed. 🙂

It is still that way.  It makes sense because there is no front panel loaded when an RT application is running.  Exceptions are the remote front panels and the cRIO-903X controllers that have a Display Port that you can enable.
