Retrive images from local database(.sdf) to picturebox in c#

Question

Hi,
  Small help.... I need to get images from my local database(.sdf). I saved image into  local database but i cant get it to my picturebox in my application. My codings are

                string sql = "Select gift_img from gift_entry where gift_points = '" + comboBox_id.Text + "'";

                if (conn.State != ConnectionState.Open)

                    conn.Open();

                SqlCeCommand command = new SqlCeCommand(sql, conn);

                command.CommandType = CommandType.Text;

                command.ExecuteNonQuery();

                SqlCeDataReader reader = command.ExecuteReader();

               

                reader.Read();

                if (reader.HasRows)

                {

                    byte[] img = (byte[])(reader[0]);

                    if (img == null)

                        pictureBox1.Image = null;

                    else

                    {

                        MemoryStream ms = new MemoryStream(img);

                        pictureBox1.Image = Image.FromStream(ms);

                    }

                }
this same coding was worked in sql database.. but this is not worked in local database...
