Ever wanted to create your own syntax-highlighting editor? Scintilla is a source code edit control, similar in concept to Microsoft's RichEdit control, that supports things like syntax highlighting, code completion and call tips. It also supports things like the use of proportional fonts, bold, italics, multiple foreground and background colours, and multiple fonts. The source code is available free, and the licence allows you to use the control in any project, free or commercial. You may also want to check out the Free Spell Checker Libraries, Source Code, Controls, Components to avoid reinventing the wheel.
