Question

Right now, the line of code I’m worrying about looks like this:

listView1.Items.Add(additional + message, icon);

Works fine, but only in Form1 of course. What do I need to do if I want to use the Add() method of my Listview from another class? (Multithreading ‘n stuff.)

Add a method on your form:

    public void AddMessageAsync(string message, int icon)
    {
        Action<string, int> handler = (aMessage, imageIndex) =>
            listView1.Items.Add("someMessage" + aMessage, imageIndex);


        BeginInvoke(handler, message, icon);
    }
