Mac CFPreferences Access

Overview

This is a example of a LLB file including two VIs that allow access to store and retrieve persistent data in the OS on the Mac.

 

Description

Here are two VIs that allow access to store and retrieve persistent data in the OS on the Mac.

CFPreferences Set Application Value 2012.vi (or CFPreferencesSetAppValue.vi) uses a Call Library Function Node to call the function CFPreferencesSetAppValue to store a string for a given key/applicationID.

CFPreferences Copy Application Value 2012.vi (or CFPreferencesCopyAppValue.vi ) uses the same way to call the function CFPreferencesCopyAppValue to retrieves a string for a given key/applicationID.

Very simple functionality.
