I am currently making an rpg using Winforms for a school project. However my knowledge on classes is so limited that I'm having trouble making a proper class that takes in data from 1 form, is used in the second form, then sent back to the first form.

The process I'm trying to accomplish is like this:

• main form opens a second form that displays items in a listbox. 1

• when you select an item and press a button to use it, the items effects are applied. 2

• The data for the effect is in the first form where many other calculations are made with the same data. 3

I keep running into the problem of making a new object of a class and the data from the first form is reset. How would I go about either using an existing object from the first form, or creating a reference class maybe?

This is the function I want to run on the first form when the button on the second form is clicked.
