Rich Edit controls

Are there any good Rich Edit control tutorials out there?
Already searched google, probably I am not good at choosing the right keywords.

Ken Fitlike has a good Rich Edit example on his web site.

Well, I had a specific problem with Rich Edit controls: I couldn't get them working!
Then I found that my richedit.h is not for version 4.1 but for 3.0 and I couldn't get any newer ones. So I just renamed the class name to "Richedit50W".

Everything else about Rich Edit controls can be just looked from the MSDN reference.
