Hyperlink in a RichTextBox

Does anyone know of a way to embed a hyperlink into a richtextbox's RTFText?? I want the user's of my app to be able to type notes for a customer into a richtextbox, and I want to give them the ability to type a internet address and I want it to be displayed like a hyperlink (with the hotspot cursor, and appear underlined) and I want it to trigger some kind of code when clicked on. Perhaps this is not possible with the RichTextBox. If not, does anyone know of another control to use??

Thanks,
Rippin
