This Custrom probe is useful for browsing the contents of a variant.

It will try to parse all the fields in the variant (notify me if you have a fail).

It will track the history of the variant and allow you to pause on a change.

It will present the data in a tree structure, allowing you to browse through the history.

Be warned, the tree structure is great for viewing, but tracking a lot of history (>50 or so) will slow down the update of the tree.

Version History:

• 2.4: Immediate updating after changing of attributes
  Rebuild in LabVIEW 2011
  
• 2.3: Fixed a bug that caused attributes not to be traversed on certain data-types
  
• 2.2: Fixed a relinking bug
  
• 2.1: Fixes a bug where unnamed cluster elements where used (http://lavag.org/topic/10269-discuss-variantprobe/page__view__findpost__p__67677)
  
• 2.0: Added an XControl
  Show XControl in palette (under user.lib controls)
  Add coloring
  Add 'user permissions' on XControl
  Add Reset on XControl
  Add optionally traversing attributes on XControl
  Add optionally colorizing on XControl
  Add optionally resetting on XControl
  
• 1.2.0: Upgraded to LabVIEW 8.5 to use Inheritance
  Support for Waveforms, timestamps and dynamic datatypes (thanks to Osvaldo)
  Added probe for an array of Variants
  Distributed as one .llb and added OGP installer
  If a Variant hasn't changed it's not decomposed (optimization)
  
• 1.1.0: Support for attributes of variants
  
• 1.0.1: Controls placed on a seperate pane
  Resize tree to upper pane
  Hide unused columns
  Limited maximum history length (default 10)
  Window resizable
  
• 1.0.0: Initial release of the code.
  

Uses the following OpenG packages:

oglib_comparison-2.0-1

oglib_lvdata-2.7-1

oglib_file-2.7-1

oglib_string-2.5-1

oglib_error-2.3-1

To get these OpenG packages use VIPM

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.

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.

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?

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

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

Have fun

Ton

[Jim Kring]

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,

[Ton Plomp]

Jim, done!

Distribution:

This code was downloaded from:

http://lavag.org/ind...ads&showfile=19

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.

The datatype description will betermine the color of the tree items.

Historical data is available as well.

Version 2.0 introduces a Variant Tree XControl which can be used in any project. Located under the user.lib palette, it gives great flexibility to

the programmer.

The programmer has the posibility to give the end user permissions for the following actions:

-Reset

This will reset the whole tree contents

-Traverse Variant Attbributes

This will enable/disable the traversion of variant attributes

-Colorize

This will enable/disable coloring of the actual datatype

All of these customizations are available as properties/methods for the actual XControl as well.

Demo:

Installation method 1:

Install the VariantProbe_2.0-2.ogp using VIPM (www.jkisoft.com/vipm)

Installation method 2:

Place the contents of the user.lib folder inside the LabVIEW user.lib folder.

and you have a custom VariantProbe and xcontrol

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.

Dependencies:

The following OpenG packages should be installed:

oglib_string>=2.6

oglib_lvdata>=2.8

oglib_comparison>=2.3

oglib_error>=2.0

Known issues:

Is slow on large variants.

I like it!

Just found one small bug - it doesn't show correctly for a cluster with multiple elements of the same name (often un-named!). I think a possible fix is to change browseVariant.vi by converting the Cluster Variant to an Array of VData (using the OpenG routine), rather than pulling out cluster elements by name.

Cheers ~ Greg

[Ton Plomp]

I posted a fix (version 2.1)

I posted a fix (version 2.1)

Something seems to have got out of sync in the fix. The probes are looking for "C:\Program Files\National Instruments\LabVIEW 2009\XControls\VariantXControl.xctl"

and though they do find "C:\Program Files\National Instruments\LabVIEW 2009\user.lib\_LAVA\VariantProbe\VariantXControl__VP.xctl", the Reset method call in the probe is not shown correctly:

Strange crosslinking issue with the NI builder. I have reopened the probes and relinked them.

I found a small bug causing some of the attributes not shown.

Aside from the great-looking Xcontrol, posting tutorial videos is a great way to see the code in action.

This would be great for all LAVACR entries.

I may steal your idea in the future

[Antoine Chalons]

Any way to make the new version (2.4) support LV2010?

Starts from 2011 at the moment... cheers.
