dotnetnuke, survey module and module development

I am trying to develop a module and using the how-to guide that dnn provides along with the survey module. In the开发者_StackOverflow社区 tut they reference code behind files but when I downloaded the zip file off their site I am not seeing any code-behind files. Does anyone know if I downloaded the right package? I got it here: http://www.dotnetnuke.com/Community/Extensions-Forge/Module-Survey.aspx

And if I dl'd the right package why is there no code behinds.

Also, anyone recommend any good dotnetnuke module tutorials?

DotNetNuke Survey is hosted in Codeplex:

http://dnnsurvey.codeplex.com/

You can find the latest source package there. Module pages in www.dotnetnuke.com are not always up-to-date.

I think that the best DNN module development tutorials are still found in printed books and their code supplements, although they won't cover the latest features (No books on DNN6 yet).

I would recommend Professional DotNetNuke Module Programming by Mitchel Sellers. It is somewhat dated (2009), but still a good reference. See review.

Other books that cover module development, in addition to DNN administration, are:

• Building Websites with DotNetNuke 5 by Ian Lackey and Michael Washington. (Review).
• Professional DotNetNuke 5: Open Source Web Application Framework for ASP.NET. (Review)
