From the front panel or block diagram window of a VI, select File»VI Properties and select Protection from the Category pull-down menu to display this page.

Use this page to set options for password-protected VIs.

This page includes the following components:

  • Unlocked (no password)—Allows any user to view and edit the front panel and block diagram of the VI.
  • Locked (no password)—Locks the VI so the user must unlock it from this page to edit the front panel or block diagram.
  • Password-protected—Protects the VI with a password so the user cannot edit the VI or view the block diagram without the correct password.
    Caution  VI password protection does not encrypt block diagrams. For maximum security, remove the block diagrams from your VIs. Refer to the KnowledgeBase at ni.com for more information about the security differences between password protection and removing block diagrams.
  • Change Password—Changes the password for the VI.

You also can use the Lock State:Set method to lock a VI, unlock a VI, or set the password of a VI programmatically.
