highlight words with colour in RichTextBox control

I have a VB application with RichTextBox control that I load with text from a text file. During runtime, I want to replace few words and highlight them with some colour. I need some way desperately.

Thanks in advance.

Use the selcolour property of the richtextbox to colour a selected area

'the words "is a" will be green
eg. with richtextbox1
.text = "This is a test"
.selstart =6
.sellength =4
.selcolour = vbgreen
end with

correction sorry, spelt color wrong

with richtextbox1
.text = "This is a test"
.selstart =5
.sellength =4
.selcolor = vbgreen
end with

You can also do it this way

with richtextbox1
.text = "This is a test"
.find("is a")
.selcolor = vbgreen
end with

Dustybryn, Thanks for quick reply. Here are my comments:
1) FIND will highlight only the one word.
2) selstart, sellength with selcolor works fine, if multiple words to be highlighted. I already knew this way.
Please see my requirement as follows:
Dim X,Y
X = "S"
Y="SET"
rtfTextBox1.Text= Replace(rtfTextBox1.Text, X, Y)

I want to make sure that all the replaced words i.e. "SET" are highlighted.
