MSDN magazin can be downloaded for free as compiled html (pretty hardcore .chm files though):
If you just look for code in <pre> tag examples, Oreilly open books do contain that. For example: http://www.masonbook.com/book/
Several Wrox and Addison Wesley titels came with a .chm version on the book CD. (Maybe you have one)
I would like to sent you a chm book, that even does have ACSCI tables in <pre> tags.
