That is unrelated to the question. How can I delete it?

The SharpDevelop code text editor didn't work for me. The other article worked well, although the line numbers would only update when I changed the text, instead of scrolling.

Oh, nevermind. I didn't know that it was a link.

I don't get it...

Hello. I'm trying to make an IDE for a seperate programming language called DarkBASIC. Everything is going perfectly fine, but I'm trying to be able to show line numbers in the editor, which is a RichTextBox control. So is there a way to show the line numbers in a RichTextBox control? And if there isn't, is there an alternative?
