    /// <returns>connection string of type const</returns>
    public static string GetConnectionStringOfDatabase()
    {
        try
        {
            string cnc = @"data source=OnlineVertrag.mssql.somee.com;workstation      id=OnlineVertrag.mssql.somee.com;packet size=4096;user id="xxx";pwd="xxx";persist security info=False;initial catalog=OnlineVertrag";
            return cnc;
        }
        catch (Exception ex)
        {
            bool rethrow = ExceptionHelper.Handle(ex, "Business Logic");
            if (rethrow)
            {
                throw;
            }
        }
        return null;
    }




 public bool CheckIfUserIsActive(string username)
        {
            SqlConnection connection = new SqlConnection(SQLDataHelper.GetConnectionStringOfDatabase());

            try
            {
                connection.Open();
                SqlCommand cmd = new SqlCommand();
                cmd.Connection = connection;
                cmd.CommandType = System.Data.CommandType.Text;
                cmd.CommandText = @"SELECT IsActive "
                                + "FROM Users "
                                + "WHERE Username = @Username";
                cmd.Parameters.Add(new SqlParameter("@Username", UserName));

                SqlDataReader reader = cmd.ExecuteReader();

                bool isActiveValueFromDataBase = false;

                if (reader.HasRows)
                {
                    while (reader.Read())
                    {
                        isActiveValueFromDataBase = Convert.ToBoolean(reader["IsActive"]);
                        if (isActiveValueFromDataBase == true)
                        {
                            return true;
                        }
                        return false;
                    }
                }

                reader.Close();
            }

Mistake #1: Posting login information in a public forum.

Seriously – everybody who views this page and looks at the edit history of the question can now login to your database. You should change the password ASAP.

Mistake #2: Storing a connection string in code. As you just saw – password changes can come quite unexpectedly. Easiest way: store in the web.config and use ConfigurationManager.ConnectionStrings to access them:

Possible mistake #3: Try “data source=OnlineVertrag.mssql.somee.com;user id=xxx;pwd=xxx;initial catalog=OnlineVertrag”. Maybe the spaces between “workstation” and “id” are the problem.
