Thanks for response Jim.Here is the problem.
Here are all the files involved. I am completely stuck here. Note that the error shown suggests I am running asp.net 1.0 yet I think I have configured matrix to use asp.net 1.1. All this code is box standard from the book beginning ASP.NET 1.1 with
vb 2003 EXCEPT for the fact I am trying to use the SQL data store of WroxUnited.
Please please can you get me help.
This is the DataAccessCode.
vb that compiles to the .dll
