Count the Number of Controls, Indicators, and Nodes in a VI in LabVIEW

[Cameron-T]

Overview

Some developers are interested in the number of Controls or Indicators on a Front Panel or the number of Nodes on a Block Diagram. This is a good way of measuring code complexity. This example illustrates the properties that can be used to get these counts.

Description

This VI uses Front Panel property Controls[] and the Block Diagram property Nodes[] to get references to all respective items in an array. The size of this array returns the count of the respective items. In the case of Nodes on the Block Diagram, a Loop or Structure along with any code inside of it will be counted as a single Node. To account for all of the Nodes inside of a Loop or Structure this VI implements an algorithm to find all Nodes on all Diagrams of a Loop or Structure. Notes are included explaining how to account for nested Loops or Structures.

Requirements

• LabVIEW 2013 (or compatible).
  

Steps to Implement or Execute Code

1. Download the VI
2. Open the VI
3. Choose the path of a VI you would like to get a count for
4. Run the VI
