将Microsoft Visual Studio 2010连接到SQL Server 2008 R2数据库

Question

I want to use my database in Visual Studio. I attach the database in SQL Server and when I want to run the project in Visual Studio 2010, I get this error:

http://i57.tinypic.com/2cz3rra.jpg

I enabled TCP/IP and disabled the firewall, and in SQL Server, remote connection is checked. My port is 1433 and everything is ok for Enable remote connection.

I connect to SQL Server by localhost .. and don't know what is my instance

Perhaps my project is not work good and error is for my project ..

I put my project link in first comment , any body can check it for errors ? This is very important for me !!

Answer 1

Check whether your id has access on the specified database(and server) or not. Also check whether you've enabled SQL server browser or not. Required services for the server in SQL configuration manager should be running.

Answer 2

检查您的连接字符串，或者您的防火墙正在阻止连接
