Accessing a Form's Controls from another Class

[ZMeister]

I have a form that creates an instance of a class that processes some data
when a button is pushed on the form. In this class that processes the data
I would like to update a listbox on the form. I cannot figure out how to
get a hold of the listbox to add items. I have changed the listbox to
public... I can get the listbox in the form button_click handler but not in
the class that it creates.

What can I do about this.??

Thanks, ZMeister.

It's good design not to reference a UI element, like a form, from a class.
In the class, you can raise an event. The form should handle the event and
update the listbox with the data given by the event parameters.
