String manipulation

[jfloan]

I have a string that can vary in length. The length can be anywhere from 1 to unlimited characters. How can I change the 10th character from whatever it is to a 'N'? Thanks in advance.

This is a start

If Textbox.Text.Length > 9 Then Textbox.Text = Textbox.Text.SubString(0, 9) & "N" & Textbox.Text.SubString(11)

Thank you very much. It is definitely a shove in the right direction.
