Change the text of a line vb 2005

[BarryM]

Say if there is a bunch of writing in a text box and you want to change the first line to lets say "line 1" and the last line to "last line" but keep the lines in the middle the same text, how can i do this

i had tried this but failed

dim last_line as integer = txttext.lines.length -1
txttext.lines(0) = "line1"
txttext.lines(last_line) = "last line"
