Smooth Scrolling (Rich Text Box)

In the visual studio IDE, when you use the mouse scroller (up or down), it moves only for a little while, and nice and smooth, and it doesn't get faster if you move your mouse wheel faster...

I am wondering how I can get the same result in my rich text box.. It is sort of an IDE itself (IDE being an integrated development environment) but on a much lesser scale.. I will be using syntax coloring and things like that, and I really just want a nice smooth scroll, does anyone know how to achieve this?

Thanks
