Not hard at all if you know the answer. I guess thats why I asked.

But you'll have to dumb it down a bit more for me.

for i = 0 to x
me.textbox2.text=textbox2.text & " " & aa(i)
next i

gives me the same result as I had before I added the me. windows form bit. It goes through the loop and the user only sees what comes out at the end.
