struct

[labview99]

Hi,

I would like to know if there is any structure in LABVIEW to create as a library where I can save one name and its numerical value.

For example, I save:

RESET  8

START   12

OFF       64

In that way, if I want to compare if Reset is bigger than 12, I don´t have to put all  the time that the reset has the value 8. I write one string constant with the name "Reset" and I know that this name is going to have the value 8 saved.

Best regards

The way you describe this problem seems to indicate you are looking for a LookUpTable (LUT). These LUTs can be implemented using VariantAttributes (in older LabVIEW versions) or using Sets/Maps (in recent LabVIEW versions)…

You also should link to your other threads to give a broader view on your problem, like this or that…

Btw. why should "Reset be bigger than 12" when you define it as value=8?

The comparison was only one example. It is just compare with one number. So, this "set attrobute" would work like one struct? I would have all the names that I want with its corresponding value?

I have read that I cando it also creating a cluster in LabVIEW that duplicates the layout of the C struct. Then I have to configure the call library function node,  as "Adapt to type" and  I have to wire the cluster to the input for that parameter. But I don´t know how to configure the call library function node, could you help me please?

What I want is to create as a library in LABVIEW to save, for example the name of ine person and his age.

JHON=30

MARY=23

So, when I use the names in my program, it is going to be like if I was using the age.

I don´t know if I have explained better myself

Hola

Estoy tratando de hacer algo parecido. Solo que mas sencillo. Me gustaría guardar el nombre de una persona y su edad. Así en mi programa puedo comparar quien es mas mayor utilizando los nombres en vez de sus edades, porque cada nombre tendrá grabada una edad.

Hi 99,

see this old thread about using Variant attributes to create fast LUTs!

Are you able to use LV2019? Then you should use maps to create your LUTs…

Why do you mention the CLFN at all? How is it related to your current problem???

So you still need a LUT? Why does it has be (some kind of) library? Please explain all details of your problem!

All your questions indicate you really should take the Training resources offered in the header of this LabVIEW board! Did you take any lessons so far?

You have been told to post in the Spanish regional board when you want to write in Spanish.

It also doesn't make sense to ask for something similar, but still different, in a very old thread.

Please stick with one thread per problem!

My problem is that I want to create as a library to save the name of a person and her age.

For example:

JHON=30

MARY=23

....

And the I want to compare people and see who is taller. I mean, instead of being comparing the ages I compare with the names of the pepople because its one has the age saved.

So you want to create a LUT. See explanations and links above.

Why does it has to be "created as a library"? ("Library" refers to either LabVIEW LLB files or Windows DLLs in my understanding…)
