Visual Basic Coding. Text box?

My Visual Basic knowledge is little, I need the following to happen:
at the tick of "Timer1" check if "textbox1" first line of text is empty (no spaces or anything)
If it IS NOT empty, do nothing.

if it IS empty then "textbox2" will add a line (like hitting enter) that line will be selected for new text, and the first line in "textbox1" will be removed bringing up the second line to first.

Html coding? Look up "html coding cheat sheet" or maybe use this img=scr"(image here)>
For basic text on a page, use <p>texthere<p>
