Lock State:Set Method
Short Name: Lock State.Set
Installed With: Base Package
Class: VI Methods
Sets the lock state of a VI. If interactive is FALSE (default), you can use password to either unlock a password-protected VI or set the password of an unprotected VI. If interactive is TRUE, LabVIEW ignores password and displays a dialog box that prompts you to change the lock state.
This method is similar to the Unlocked (no password), Locked (no password), and Password-protected options on the Protection page of the VI Properties dialog box.
