Alright, lets say I have a list box on my form that has the text Se7ensins, Halo Modding, and GoW modding. I also have this code: Code: richTextBox1.Text = richTextBox1.Text + " " + listBox1.SelectedIndex; Now if I already had the text Se7ensins in the text box, once I click my button it will say Se7ensins-1. Then if I select another index it will add -1 again to my rich text box. But what I want it to add is Se7ensins or GoW modding. How can I do this?
