Thanks for your help, but i think thats is a more complicated than i was thinking. On my design i have a textbox for input, a calculate button so when you press it then i either need a message box or a list box shows that shows the diamond. I was reading in abook about loops, can this be done using loops starting with the "Private Sub btn1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn1.Click" code


Thanks again for your help
sorry if this is lame
