Overview

Coding that exemplifies how to recognize only alphanumeric keys.

 

Description

This is a simple VI that will only pass through alphanumeric key entries and will filter out any other keys. It only passes through the keystrokes themselves that are alphanumeric. Capitalization plays no part in this. Also, note that the 10-key portion of traditional qwerty desktop keyboards is also filtered out.

 

Requirements

LabVIEW 2012 or compatible

 

Steps to Implement or Execute Code
1. Run the VI
2. Press different keys
3. Stop the execution with the Stop button.
