Positioning at the end of a textbox

Combo1.AddItem Text1, 0
Combo1.Text = Combo1.List(0)
or
Combo1.AddItem Text1
Combo1.Text = Combo1.List(Combo1.ListCount - 1)

If you're using a TextBox, use the VbNewLine to
create a newline everytime something is entered.

I think I know what you are looking for:

Is the textbox only one line in height?
if so try this easy piece of code

Code:

---

Text1.SelStart = 0
Text1.SelLength = 0
Text1.SelText = "New Text" & vbCrLf

---
