Installed With: Base Package

This method is similar to the Protection box on the General Settings page of the Project Library Properties dialog box.

Parameters
| Name | Required | Description |
|---|---|---|
| lock state | No | Specifies the level of editing permission to set.
|
| interactive | No | Specifies the way in which you can use passwords with the project library. The default is FALSE, in which you can use a password to unlock a password-protected project library or to set the password of an unprotected project library. If you set interactive to TRUE, LabVIEW ignores the password and displays a dialog box that prompts you to change the lock state. |
| password | No | Specifies the password to set for a project library to which you want to add password protection, or the password to use to unlock a password-protected project library. |
| put in cache | No | Specifies whether you want to cache the password specified in password. The default is FALSE, which does not add the password to the LabVIEW password cache. |
