Hi, There! I didn't visit to this that It was for a long time.

Until This Time, I was building My Another Project.
It was need to some text editor. So I did making with learning api(window). But I faced the problem that I need the editor with
various functions like line number , syntax highlight ...etc.
However , I Got Some Informations That it's knowledge About Rich Edit Box Recently. So I was excited about that. but I don't know
what is rich box , how use it and how i use that in DBPro.
I need some helps.
