Want to highlight a piece of string in Rich Text Box

you can use the prebuilt class as follows...

richTextBox.Select(start_index, length_of_text);
richTextBox.SelectionColor = Color.Red; // or custom color, whatever

If you are using a large richTextBox, then doing it this way is a terrible idea, its very slow (if you're highlighting things all over the place)... I have previously made a class that writes a .rtf file to disk and then loads it into the richTextBox... that method is magnitudes faster, but considerably more complicated (unless you use my class ;) ). If you can manage to squeeze all of the rtf code into a string (or maybe use an array of strings), then you can also use richTextBox.Rtf = "... "
