Question

How do I syntax highlight in a richtextbox control AS THE USER TYPES and USING A String[] keywords. I will be publishing a lightweight notepad to the web soon

Answer 1

The Scintilla control is an excellent source code editor that includes syntax highlighting amongst a whole range of other features. You can embed it in your own app and there is a .NET wrapper available.

With Scintilla you can specify the keywords and it will then apply the syntax highlighting as you type.
