Hi guys, I have just set up a database in SQL 2005 Express Edition. However, I have a problem accessing it with the application program created in VB 2005 EE. Before using SQL 2005, the application worked perfectly in SQL 2000.
Here is my connection string used in SQL 2000:

Dim sqlConn As New SqlConnection("Data Source=(local); Database='Inventory List'; Integrated Security=yes")

Is this valid in SQL 2005 Express Edition? Or should I change the connection string instead? Thank you very much.

The normal connection string for express would be;

Dim sqlConn As New SqlConnection("Data Source=(local)\sqlexpress; Database='Inventory List'; Integrated Security=yes")

|||Did you enable remote connections for the SQL Express instance ? See the Screencast on my site for more information.
