I am a beginner/intermediate user of VBA but I would like to get much better. I am particularly interested in learning how to use class modules. I have read the chapter on this subject in the Litwin, Getz, Gunderloy book and I am left scratching my head. I have also read Beginning Access VBA 2003 by Cosnell. I learned a lot, but felt that her "How it Works" sections just repeated the preceding section rather than give an explanation.
I am looking for a book/resource that will explain this concept step by step with many more detailed examples, especially concerning more advanced techniques such as building class hierarchies. (I can already create very basic class modules.) Suggestions would be most appreciated.
Thank you and regards,
