Pointer in LV?

[TriStones]

Hi there.

I am working on a set of instruments which have 2 similar monochromater to be selected.

like:

As are shown above, I am wondering if pointers are available in LV, so that I can just add a small case structure in initialization.

Is it possible?

Thanks!

If you are looking for a way to group the objects, it is better to use cluster (don't forget to make it strict-type-definition). There are something similar to pointers - data value reference, and a control reference.

Hi, Micheal, seems DVR is not available in LV 8.6??

[TriStones]

Actually, mine is ancient LV 8...

You can also use LV2 globals (Action Engine)

No, there are no pointers in LabVIEW. And in many ways that's a good thing. As for your specific issue, it sounds to me like you'd benefit from LVOOP programming.

Yes, he would benefit from LabVOOP, but LabVIEW classes were introduced in LabVIEW 8.2.  However, you can get object-like functionality without LabVIEW objects.  The two best ways to do this in LabVIEW 8.0 are single-element queues and action engines.  I prefer the single-element queue approach, as it is closer to the syntax of LabVIEW objects and more scalable.  Refer to the two linked tutorials and keep posting if you have questions.

Good luck!

Hi TriStones,

Please let us know which approach you choose and any questions you have along the way.

Thank you,
