Hey guys I have what should be a simple question, but I am new to C# so I am having just a little problem. I am using the following connection:

SqlConnection conn = new SqlConnection(@"Server=myservername\SQLEXPRESS;Database=Names;");

I have also tried to include user id and password but my login always fails.

I think this is because I am not really sure what username and password to use.

With my sql server I am using windows authentication… if that helps.

does anyone know which username and password I should be using? or another way to do this?

I have seen that I may need to turn remote access on in my sql settings, can anyone tell me how to do that?

Thanks!

    Your connection string should specify that integrated authentication (Windows authentication) has to be used. Otherwise it tries to do SQL user/password authentication, which is disabled on the SQL Server by default, and if enabled it doesn’t authenticate against Windows users.

    Server=.\SQLEXPRESS;Database=YourDatabaseName;Integrated Security=SSPI;

    Remote access is only required if your application and the SQL Server Express instance aren’t on the same machine (which is why the sample connection string here has a . for the server name, which represents the local server).
