Mike,

I have Kevin's book, but I haven't downloaded his sample code. How is the current SaveDataSet() method currently coded? Does it not include a way to work with a multi-table DataSet? I've not written any "generic" data access class to do this sort of thing (all my data access classes are specific to what's being updated), so looking at the code for the sample SaveDataSet() method that you're already using may give me some ideas of how to "generic-ize" it. <g>

However, I was trying to use Kevin's business objects, from Chapter 8, where there is a generic SaveDataSet() method in the DataAccessSql data object in the Data.cs file, where commands are built on-the-fly for the DataSet passed in.
