I've done a little Notepad clone with VB2003

It works great. Now, what I want to do is to set different opacity to my text area (is a richtextbox object), which should be seted on runtime by a trackbar.

I want it to be just like this picture, setting the background area but not any of the text typed.

Can I do this?

I thought that I could set the richtextbox background color to a "almost" white (RGB:254,254,254), to be more simple to detect the area that I want to set a different opacity.

Thank you.
