Numbering (bullet) problem

In richtextbox I use this code to make numbering (instead of bullet)

Code:

---

       
        RichTextBox1.SelectionBullet = True
        SendKeys.Send("^+{L}")
        RichTextBox1.SelectionIndent = 10

---

and under the numbering, I use this code to make indention with (a, b, c)

Code:

---

       
        RichTextBox1.SelectionBullet = True
        SendKeys.Send("^+{L 2}")
        RichTextBox1.SelectionIndent = 20

---

now the problem is after it, i will use again

Code:

---

       
        RichTextBox1.SelectionBullet = True
        SendKeys.Send("^+{L}")
        RichTextBox1.SelectionIndent = 10

---

the numbering start again with 1, instead of 4 (because 3 is the last number)

kindly correct my coding please?

try this control for Numbered Bullet....
