Hi Mike-

This makes sense to me. I have been using Codebook for the last year or so and the problem is that the busobj displays messages when errors occur. I like the idea of having the busobj store error info and then allowing the client to retrieve the error message. This is exactly the type of approach I was looking for.

When a method fails, like save, the calling object calls the business object's GetErrorMessage method, which just returns the error message as a string. GetErrorMessage basically stores cErrorMessage to a variable, clears the property and returns the variable. SetErrorMessage accepts a string, which is added to the existing error message, which is nice in case multiple business rules were violated. It's actually a little more complicated than this because GetErrorMessage actually polls member objects for errors as well, but you get the idea.
