How to update a listbox in another thread in another class

[yeah1000]

Hi, i need to add some items to a listbox in another thread and another class. The secont thread passes a ListBox item to the invoking function but i cannot access its listbox.items.add functionality. I can only set values to the common parameters to all Controls (i.e. text, name etc.) How could this be solved? ty

Create a custom event (and custom EventArgs object). Put the string/item into the EventArgs object and handle the event in the desired location.

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.
