Sorry for not explaining the situation properly.

I know to set a color of text of a RTB,but actually what I wanted was Syntax Highlighting.

I did not know this word "SyntaxHighlighting" before.

Answer 4

If you want to Syntax Highlight in that scenario simple select the text by using appropriate method. Nothing else you have to do in my last post i mentioned charformat didn't observe you are not using Winform app

Just as a heads up from someone who had done syntax highlighting in a Rich Text box before -- it is the wrong tool for the job.  Yes you can kind of get it done by monitoring the EN_CHANGE notification, but it is painful at best.  Most of the time you feel like you are fighting the built-in formatting of the rich edit box.

I went the route of writing one from scratch -- not something I would recommend either.  You might check out Scintilla which is a free source code editor you can integrate.  Its license is quite permissive and unlike the Rich Text it is designed for source editing with syntax highlighting and all the other goodies you want in a code editor.  I wish I had known about it before I wrote one from scratch.
