>If you look at the code, you'll see that the code uses tableadapters and business objects to accomplish the functions. You can ignore projects not referenced in the business layers as far as data is concerned. there are some projects that are left overs after the refactor that I use to show how it was done.

John,

I feel very upset. I haven't made any real progress yet and I wish to move with this to some point. Are you sure you don't have the exact project for your article somewhere? The Bird Watcher project even if it uses the same principles is not the one I want to concentrate at the moment. I want to see simple Orders Data Entry application.

Thanks again.
