How to Highlight a sentence row by row? For example I made a simple notepad written in VB.net. Then, I'd like to hightlight a row by row automatically and manually. lets say I have a button named "auto" to highlight row downward automatically , and I have a button named "downward" to highlight row downward everytime I click the button downward, and button name "upward" to highlight row upward everytime I click the button upward.
Thanks for advance.
