I get what you mean, just don't know how to help, sorry.
And for people who doesn't get it, I will try to explain:
A program that has a textbox, and it's text count all the way to a certain number, but he doesn't want it going like this:
1 2 3 4 5
He wants it going down, not to the side, like normal, but down, like this:
1
2
3
Hope I explained it a bit
But one thing I DO know is that you need to have the textbox on multiline, and have it opened up on the top and bottom.
It's better with a RichTextBox, so it will have a scroll bar
