Hi!!  
I am trying to populate a listview with num data from a system file, and update it when the user adds more nums to the file. Is this possible? I’ve found examples of this being done with signals but not data. I am using RAB 5.11 and [VB.Net](http://VB.Net). Any help will be greatly appreciated.

Thank You,  
Rick
