I've never used the Class Designer, so I took a quick look at it in my little test app. I guess it could be useful. <g> Although, there is a limit to the usefulness, as you obviously discovered. There appeared to be plenty of methods that I couldn't run.

Your error is probably the result of the fact that your method needs to access data, going through the DAL and utilizing the app.config. I guess you just can't test this type of functionality in the Class Designer.
