This code lets you to Print, Save to file, Load data from file to/from ListBox or ListView object.

Listbox related functions:

PrintListBox -Inputs: ListBox object
ListView related:
SaveLV -Inputs: ListView object, Subitems amount in that object, Directory where to save

I fogot to say that those ListView functions assumes that ListView viewmode is lvwReport and you should have one or more subitems in that object, Sorry ;)
