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

MS SQL 05 auto increment

Hello,

Firstly Hello to everyone I'm new the forum and fairly new to .net

I'm working on web datbase application using visual studios 05 and MS SQL05 I've used 2003 (briefly) before but 2005 is very new to me.

To my problem I download the GUI interface from microsoft so I can now setup a local database and do my own testing.

I have created the table and fields with in it however on a particular table i have made a primary Key and left it as an INT but I would like to set it as auto increment ! I dont know how to select that option as i was used to mysql way of doing things or does this have to be done as a stored procedure ?

Any assistance much appreciated.

in the management studio you can right click on the table name and click on "modify table" then in the right pane select the column you want to set autoidenty on to and in the bottom pane check the Identity property.
