Overview
This VI forces user to enter a valid password before the program executes.


Description
This VI was created to add a password string to stop people viewing the front panel data until the password was correct. Initially the user can only see a password field. Once they enter the correct password (in this case "labview"), a graph appears and begins updating. Since the password is visible in the block diagram code, this method will only be useful with a password-protected block diagram or a deployed executable.

 
Requirements

  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

 

  1. Click the Run arrow
  2. Notice that the front panel displays nothing
  3. Type "labview" into the string control
  4. Notice that the front panel now displays
