Problem connecting to sql server
I have downloaded the code for ASP.NET INstant Results chapter 7(Wrox Photo Album). I am using SQL Server 2005 standard edition. The database files are located in App_Data folder. I am not able to connect to database
"Connection to the server failed. Servername/instance cannot found"
As I have other applications in my system and are connecting well. I changed the ConnectionString in the web.config file as with my current running application changing the database name.
What could be the problem.
How can I attach the photodb.mdf file in sql server database?
Thanks in advance
