Hello.
IMHO, there is another book (quite new) that is better than the Pro DNN 4 book written by the core team, for beginning module development,
that is . . .
"Building Websites with VB.NET and DotNetNuke 4" by Daniel N. Egan, Michael Washington, and Steve Valenzuela.
In fact, one of the authors is a member of the core team.
The chapter on Custom Module Development is excellent. I followed through all the instructions and code to build a simple "Hello World!"
module and the corresponding Edit page with little difficulty. In sharp contrast to getting through the Pro DNN 4 book for the same task
(building a "Hello World!" module), after spending the entired afternoon trying to figure out the proper VS to use and the right source to
download and use to no success, I abandoned utilizing the Pro DNN 4 book.
