Is there any way for Syntax highlight emulation?
Scan RvData and change styles...

Do you need a realtime syntax highlight?
See TSyntaxRichViewEdit on http://www.trichview.com/resources/ . It is quite a basic and slow component, so it can be used for very simple highligting in relatively small documents.

Or do you want to display a preformatted highlighting?

I know TSyntaxRichViewEdit but I don't need realtime syntax highlighting.
I want to create special button "Pascal highlight" or "HTML highlight" and reformat existing text (or selection).

I think the simplest way is to read the selected text, then to add it to a hidden RichView (using normal AddNL methods) using proper styles for keywords. Then save data to stream (SaveRVFToStream) and insert it back (InsertRVFFromStreamEd)

Thanks, I try to use this method.
