Another new addition to our Web offerings: the online code formatter. It is based on the syntax highlighter of SharpDevelop's text editor, and thus supports quite a few formats out of the box: SP/XHTML, BAT, Boo, Coco, C++.NET, C#, HTML, Java, JavaScript, Patch, PHP, TeX, VBNET, XML. In addition the Web form, I also added a Web service that can be used in your application to perform code conversion, a sample is available.
Noteworthy: the Web offerings are built upon the sample you can find in the source download (revisions 2522 upwards) - \Samples\HtmlSyntaxColorizer.
