Description:

A custom 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 determine 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 possibility to give the end user permissions for the following actions:

-Reset

This will reset the whole tree contents

-Traverse Variant Attributes

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, or you access them (while the owning VI is in edit mode) via the short cut menu.

Installation method 1:

Install the OGP file using VIPM (www.jkisoft.com/vipm)

and you have a custom VariantProbe and xcontrol

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

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.

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)
