    To Whom It May Concern:

      I learning Visual Basic and tried to connect to SQL Server in a Vb Project after making sure that I had SQL server running on my localhost and that I had copied and pasted the password to the connection string:  “A network-related or instance-specific error occurred while establishing a connection to SQL Server.   The server was not found or was not accessible.   Verify that the instance  name is correct and that SQL server is configured to allow remote connections.  (provider: Named Pipes Provider, error 40 – Could not open a connection to SQL server). ”  I even wondered whether there was something wrong with the Vb environment, so I tried connecting to an Access database—no problem.   What gives?   Thanks!

  2. Hi Peter,

    You need to make sure that when you’re connecting to your local server that you use the dot syntax (.) to identify the local machine. If you are running SQL Express (which is by default installed with Visual Studio) you would refer to it as .sqlexpress

    The easiest thing to do is add a new connection from Visual Studio’s Server Explorer and use the dialog and put a dot (.) in there for the server and see if you can browse the databases.

    Note that if you are using Visual Basic Express 2008, you can only work with local data files like Access, SQL Express detached MDF files and SQL Compact .SDF files.
