Question

Setup: A form with a text box, a button, and a list box. The list box has ~10 values that are added to it when the form loads.

I’m wondering if it is possible to write the code for the button so that, when pressed by the user, it would add whatever text is in the text box to the list box and change the code of the form load to add that text to the pre-existing listbox.items.add’s that are in the code of the form load.

Answer 1

From my comment:

You need a data source, either a file or a database, etc, to save your information that is used in the list box.

and as you commented:

So something like a text file that holds all of the items, and then append the latest item to the text file? So that the next time the form loads, the new text file is used?

Yes, that is a viable solution.

If using files, make sure to use the Environment.GetFolderPath(...) as the path location. You should almost never use your executable’s path for storage location.
