Distribution:
This code was downloaded from:
the LAVA CR

Description:
A custrom probe to put on a variant.
It will create a tree based on the variant data, and populate the tree with the data, the attributes of the variant will be shown as well. Historical data is available as well.

Installation method 1:
Install the VariantProbe_1.2-3.ogp using VIPM (www.jkisoft.com/vipm)

Installation method 2:
Place the VariantProbe.llb inside one of the following dirs:
-\_probes
-\Probes

and you have a custom VariantProbe.

Don't forget to remove the old version manually if needed!

To use it add a probe to a variant datatype or to an array of variant's.

It can pause if the data changes, and will notify you if a change happens.

Known issues:
Is slow on large variants because of the use of the tree control and the recursive listing of a Variant just takes time.

Thanks Ton,

This is a cool probe...

I set the window to be able to resize and the treecontrol to size with it so I can fit more data on my screen.

Hi Ton,

Nice implementation. Were you aware that Jim Kring had already done something similar?
See: OpenG Universal Probe
Anyway, nice to see another, keep up the good work.

Sounds like an update with a resizable window is in order.

Hi Mike,
No didn't know, it looks like you had a different approach. And the old OpenG content is hard to get...
Only one question when I want to probe a non-variant data type I get this error:

Has the probe engine changed?


Here you go! And you used another screenshot (mine was too big I assume?)?

Have fun

Ton

Hi Ton,

Nice job. I guess great minds think alike ;-)

BTW, in your download description you mention dependencies to many OpenG packages. Can you put a link to VI Package Manager (or OpenG.org), so that people can easily get them?

Thanks,

Jim, done!

Ton

updated to version 1.1.0, includes attributes!

Hi Ton, thank you very much for this update! Both of my favorite state machine/module architectures use variants to pass data around between modules and I use the attributes to carry things like command options, module return addresses, whether a callback is requested, etc. I've used both Jim Kring and your implementations of variant probes, and the addition of attributes is a very nice one for me. I really like the history on yours as well.

Keep up the good great work!
