Programmatically Update Array Index Indicator

[Kelly_R]

Overview 

This example shows you how you can programmatically update the indicator of your array index on your front panel.  This allows you to alter what values are visible in your array during run-time. 

Description

In this example the Index Values property node is used to update the value of the array index on the front panel to reflect the current element being updated in the array.  For this VI the value in the array are not being updated, only the index is as a proof of concept.

Requirements

LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

Open and run the VI "Update Array Index Value Programmatically_LV2012_NI Verified"

This method doesn't work if the array is a strict typedef in which case the property "Index Values" is read only.

• That loop also needs a small delay (wait), else only the last position is ever noticeable.
• The array should have some illustrative default data. Just scrolling an empty default array is relatively uninteresting.

• Programmatic scrolling of an array is more suitable for an indicator. If it is a control, it could intefere if the array is scrolled while it is operated.
