Hi,

I am trying to display data from a column in my database onto my rich textbox, but I am getting mixed up between DataSet and DataReader - I know the majority of the code below is correct, I just get two lines containing errors, and I'm not sure why:

// Create a connection string
            string ConnectionString = ("Provider=Microsoft.ACE.OLEDB.12.0;Data Source= C:\\Documents and Settings\\Harley\\Desktop\\Test.accdb");
            string SQL = "SELECT * FROM Paragraph";

            // create a connection object
            SqlConnection conn = new SqlConnection(ConnectionString);

            // Create a command object
            SqlCommand cmd = new SqlCommand(SQL, conn);
            conn.Open();

            DataTable dt = new DataTable();
            da.Fill(dt); //ERROR

            // Call ExecuteReader to return a DataReader
            SqlDataReader reader = cmd.ExecuteReader();

            foreach(DataRow reader in dsRtn) //ERROR
            {
                richTextBox = richTextBox.Text + reader[0].ToString();
            }

            //Release resources
            reader.Close();
            conn.Close();

        }
