Copy text to clipboard by finding start and stop positions in code

Hello,

Does anyone know how to copy text from a rich text box by setting the the start and stop position in the code and transfering the selected text to the clipboard?

Code:

---

    RichTextBox1.SelStart = 2
    RichTextBox1.SelLength = 3
    Clipboard.SetText RichTextBox1.SelText

---

There ya go :)

Thanks!
