ThanX megatron, it all works now

And I have another question (two).

1. I remember a while ago, somebody asked about why when loading a text from a file, adds 2 pipes. The answer was to make the textboxes multiline.
It worked fine until I noticed that when I press Down, I can't see the text and I have to go up to see it again.
When users will use my app and that will accidently happen to them, it will be very confusing.
How can I fix this? By the way, I need to leave the textbox unlocked and Enabled.

2. How do I use a ToolBar?
Adding items to it, Adding to every item of it, a picture, and making it to do things accoarding to the pressed button?
