        if (dr.Read())
        {
            txtCourseCode.Text = dr["Course_Code"].ToString();
            txtCourseDesc.Text = dr["Course_Desc"].ToString();

        dr.Close();
        conn.Close();
    }
}

mySQL = "SELECT * from Eng_Dip = @par_Course_Name";

mySQL = "SELECT * from Eng_Dip WHERE Course_Name = @par_Course_Name";

Same on line 18. The syntax is

SELECT * FROM table WHERE column = 'value'
