I am trying to run code from the book 'expert one-on-one Visual Basic .NET Business Objects from Rockford Lhotka'. The code is located on pages 108-112. When I run the code all I get is Server Error 500. I don't want to go further in the book until I get a handle on the code examples but I have not been able to get this to work. Is there something I am missing? I am running the example on a machine with IIS 5.0. If you someone knows how to get this to work please let me know. Thanks.
