Thanks a lot Kirtan for your fast reply.. Your codes didnt worked for me and I really dont know why. Is your code working on second or third lines? My string is like below; 3.note 11.01.2010 21:27:13 *********************** 2.note 11.01.2010 21:27:03 *********************** 1. note 11.01.2010 21:26:52 ***********************

Friend , here is the Code you need :) if my answer helps you then please check "do you like this answer" check box please :) it helps me . Code ---------------------- using System.Text.RegularExpressions; private void button1_Click( object sender, EventArgs e) { Regex rex = new Regex ( "[*]*" ); foreach ( Match m in rex.Matches(richTextBox1.Text)) { // Preserve Position of Cursor int pos = richTextBox1.SelectionStart; richTextBox1.Select(m.Index, m.Value.Length); richTextBox1.SelectionColor = Color .Red; richTextBox1.SelectionStart = pos; richTextBox1.SelectionColor = Color .Black; } } if you want to change Color in realTime when user types the Text then Just Place the code in TextChanged Event instead of Button Click :)
