Lock a Tab in a Tab Control in LabVIEW

[Jon_S.]

Overview

This example shows how to the user can lock (disabled and greyed) a tab on the front panel

Description

This VI  uses a property node to return an array of pages within a tab control.  It then indexes a page out of the array and sets it to Disabled & Grayed.  The Lock/Unlock control on the front panel prompts the user for the password "engineer".  If password is correct the indexed page's status is reversed to either enabled or disabled & grayed depending on its current state.

Requirements

LabVIEW Full Development System 2012 or compatible

Steps to Implement or Execute Code

1. Run the VI
2. Notice that Tab 2 is Disabled and Greyed out by default
3. Click on Lock/Unlock button to change the enabled state
4. Enter a selected password, in this case it is "engineer"
5. Notice that Tab 2 has now switched states, from enabled to disabled or from disabled to enabled

Perfect! I've been wanting to disable a tab for a while if a certain condition existed, but settled on disabling certain controls.

You can use the Page Enabled property from above to disable and gray out a tab when your VI starts.  Just make it one of the first things that execute.
