Re: Local connection to SQL Server 2005 Express fails

Thanks for the info, but I did everything suggested in those two articles
and I still get the same connection error. I also tried various alterations
of my connection string with no success. Further research indicates that
this is a common problem, so I wonder why Microsoft ships the Express
edition along with Visual Studio 2005, but makes it so difficult to connect.

If you or anyone else has any other ideas, I would be most grateful.

Thanks.

I just installed SQL Server 2005 Express edition, and created an app in
Visual Studio using C#. I get the following error when trying to connect:

"An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005, this failure may be caused by the
fact that under the default settings SQL Server does not allow remote
connections. (provider: Named Pipes Provider, error: 40 - Could not open
a connection to SQL Server)"

I enabled Named Pipes but left TCP/IP disabled because this is a
localhost connection on the same computer.

Here is the portion of the code I am using to connect:

string dbCString = "Persist Security Info=False;Integrated
Security=true;Trusted_Connection=true;Initial
Catalog=MxData;server=(local)";

SqlConnection ThisConnection = new SqlConnection(dbCString);

ThisConnection.Open();



Thanks in advance for any help.
