Hi,

When I try to singnup a new user, I get the following error message:

"{"Unable to open the physical file \"E:\\VS2010 Projects\\Silverlight 4\\MyProject\\FitnessTrackerPlus\\FitnessTrackerPl us.Web\\App_Data\\FitnessTrackerPlus.mdf\". Operating system error 5: \"5(Access denied.)\".\r\nAn attempt to attach an auto-named database for file E:\\VS2010 Projects\\Silverlight 4\\MyProject\\FitnessTrackerPlus\\FitnessTrackerPl us.Web\\App_Data\\FitnessTrackerPlus.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."} System.Exception {System.Data.SqlClient.SqlException}"

In the server explorer I can connect to the database, but after running, the program can't access it.

Does anybody can help me, how to diagnose the cause?

Thanks in advance

Gabor

Answer my own question:

On the basis of this forum:

I changed the User Instance = False to UserInstance = True in web.config and now everything working as expected.

Thanks for read that post

The UserInstance = False seems to be a new requirement for SQL Express 2008 R2, True should work for all other previous versions of SQL Express

It is strange, because I'm using SQL Express 2008 R2

I am not able to register a new user. I receive a Domain Exception was unhandled by user code error. The CreateUser method is not working. I did set the UserInstance to true in the web.config file. I am using SQL Express 2008 R2. All of the tables Nick created are visible, but I can not add any updates to get a new user. I really like the design ideas presented by Nick.
