How to upgrade sql server express 2005 to 2008R2?

SQL Server 2000 DB attached in SQL Server 2005 Express not connecting to VB .NET 2003 application now. WHY ?

  • I made a S/W using VB .NET 2003 and SQL Server 2000. Now, i uninstalled both and installed Visual Basic 2005 Express and SQL Server 2005 Express. I attached the old database (created in SQL Server 2000) with SQL Server 2005 Express and it attached successfully. But when i run the executable of my application (created in VB .NET 2003), it doesn't connect to the database suceessfully. What might be the reason for that and what should i do to resolve it ??? ... Thanks, Zain.

  • Answer:

    Check the connection string and make sure your application has access to the database. Be aware that the default instance created by SQL Server 2005 Express is (local)\SqlExpress. Use Microsoft's free SQL Server Management Studio Express to check the connection settings, connect to the database, manage it, run SQL queries, etc.
