Scroll of a texbox always on bottom [duplicate]

Question

There is a way to keep the scroll on bottom for a multi line textbox?

Something like in the vb6

txtfoo.selstart=len(txtfoo.text)

I'm trying with txtfoo.selectionstart=txtfoo.text.length without success.

Regards.

Answer 1

Ok, I found that the solution was to use

txtfoo.AppendText 

instead of

 txtfoo.text+="something"
