MS SQL database not connecting problem

hi

I usually did my database in SQL Server Management Studio Express then when I was in Visual Studios I would connect to it in the server explorer tab but I wanted to try to do it through Visual studios so I took my database files then went to my app_data folder and added them as existing items. I then went back to the server explorer tab and set it up.

Everything thing seemed to set up but when I run it I get an error.

I get this error when it does conn.Open();

Error:

1System.Data.SqlClient.SqlException was unhandledbyuser code2 Message="Cannotopen database \"Japanese\" requestedby the login.

This is what I have as my connection stuff

webconfig

1 <connectionStrings>2 <add name="Japanese" connectionString="Server=localhost\SqlExpress;3 Database=Japanese; Integrated Security=True"4 providerName ="System.Data.SqlClient"/>5 </connectionStrings>67

In my file

 
1 SqlConnection conn;2 SqlCommand comm;3 SqlDataReader reader;45string connectionString = ConfigurationManager.ConnectionStrings["Japanese"].ConnectionString;6 conn =new SqlConnection(connectionString);78 comm =new SqlCommand("SELECT HiraganaCharacter,HiraganaImage FROM Hiragana", conn);9 conn.Open();10 reader = comm.ExecuteReader();
 Thanks 

Hi,

can you check your code connection string?

it would be usually in this format for SQLserver connection in the config file:

connectionString="Data Source=yourservername;Initial Catalog=yourdatabasename;User ID=userid"

providerName="System.Data.SqlClient"

Hope this helps
