Sets the level of editing permission for a LabVIEW project library, including the password.

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

Note The LabVIEW Datalogging and Supervisory Control Module supports this method in the Run-Time Engine.

Parameters

Name Data type Required Description
lock state cenum.png Yes

Specifies the level of editing permission of the project library.

0invalid lock state
1Not locked—Users can view public and private items that the project library owns and can edit the project library and its properties.
2Locked (no password)—Users cannot add or remove items from the project library, edit project library properties, or view private items that the project library owns.
3Password-protected—Users cannot add or remove items from the project library, edit project library properties, or view private items that the project library owns. Users must enter a password to edit the project library.
interactive cbool.png 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 cstr.png 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 cbool.png 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.
