Suppose I have "Hi there" text written previously in a rich text box. But then on click of a button I want to enter some more text, say "Kaustav" into the rich text box in Bold.How can I do that.

eg.
RTB contains: Hi there
I click a button to enter "Kaustav" in bold
RTB contains: Hi there Kaustav
Bye

Kaustav

Kaustav

.selStart = Len(.Text) <- set the insertion point at the end of the text
.selText = "Kaustav" <- add this from the insertion point
