问题
I'm looking for a RichTextBox with syntax highlighting! Sounds easy but I'm searching since months and didn't find that what I need.
First I started to do it by myself... No good idea...
I tried to use this: http://blogs.microsoft.co.il/blogs/tamir/archive/2006/12/14/RichTextBox-syntax-highlighting.aspx
but that code don't handle loading files or pasting so i started to write a highlight function for inserting text-blocks. That tutorial and my code worked fine first, but then I saw a lot of tiny bugs and loading large files took too much time.
Then a found a lot of similar tutorials/codes at codeproject.com like this: http://www.codeproject.com/KB/edit/SyntaxHighlighting.aspx
But there I get problems if the file becomes large, too. Pasting and loading files will take a while...
I think I'm searching for something like this: http://www.aqistar.com/
But I don't can spent money and I want to sell my program maybe so the code/control should be free.
Can anybody help me?

AvalonEdit is the WPF-based text editor used in SharpDevelop 4.0. It has built-in support for syntax highlighting for several languages and you can add new highlighting definitions using an XML-based file format.
AvalonEdit is open-source, but can also be used in commercial applications (LGPL).
If you don't want to use WPF, you could also use ICSharpCode.TextEditor, the old Windows Forms text editor from SharpDevelop 3.x.
