Hi, I would like to implement a Run-time license checking mechanism that will enable or disable some parts of my LabVIEW API depending on a license status. After reading numerous discussions here on the forum (We need a new password cracker :( , Low level VI data editor (warning: not for production use!) , I found some more hidden INI keys, Password Security in LabVIEW) I realised few things: - reverse engineering in a LabVIEW-related field seems to be a doable task for some smart people, - password protection on block diagrams does not protect your IP, it is more of a "r -
I am trying to connect a PostgreSQL database (ver 9.6) with LabVIEW (2016) on Windows 10. I followed the following tutorial: https://decibel.ni.com/content/docs/DOC-30308 Without access to a cRIO, I have followed the steps to create the database, table and block diagram. Please see block diagram attached.The system exec.vi calls the psql.exe with SELECT command using database "lisam" and database user "postgres".

Modify the LabVIEW executable binary to ignore the password checking. I have not tried this on LabVIEW 2011, but if this works it basically means that passwords are just a sign that says 'Do not trespass' Can anyone verify the
