Question

This is my first time trying to use a database in ASP.Net, and I have a problem here:

My database is on my computer (localhost), and it throws an exception on me when I click the “submit” button :

SQLException was unhandled by user code. Login failed for user “.

    protected void Register_Click(object sender, EventArgs e)
    {
        SqlConnection connection = new SqlConnection("server = localhost ;uid=; Password= database = Movies;");
        connection.Open();
        //FirstName***********
        string firstName = UsernameTextBox.Text;
        string sqlquery = ("INSERT INTO [Movie] (FirstName) VALUES (' " +FirstNameTextBox.Text + " ' ");

        SqlCommand command = new SqlCommand(sqlquery , connection);
        command.Parameters.AddWithValue("FirstName", firstName);

Since the server is on my computer, I dont have any username, right?!

Answer 1

You do need a username and password, or else you need to use integrated security, which means that your windows credentials are used.

You can add integrated security to your connection as follows:

SqlConnection connection = new SqlConnection("server = localhost ;integrated security=SSPI; database = Movies;");
