Programatically populate a listbox in a PDA

[AJL]

Is it possible to populate a listbox programatically on a PDA? For my application, I have to record data for a specified number of parameters. These parameters are stored in a file that I can access at a later time to input more data. I can check this file for what parameters already have data. What I need to do is if a particular parameter already has data stored in it I need to remove it from the listbox so I don't have the option to change this data. This would be easy if property nodes were available in the PDA module. Can the items in the listbox be changed programatically?

Thanks,

AJL

While there are no property nodes, there are "property VIs". These can be found in the application control palette and I believe one of them does set listbox strings. If it exists, it might only be available for 7.1.
Also, there are more "property VIs" available .here [link removed; example no longer available]
