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.


Data type Name Required Description
Enum U32 lock state Yes Specifies the level of editing permission of the project library.
Boolean 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.
String 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.
Boolean 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.
