title: Read a picture from Access DB into PictureBox
body: <p>I have been trying to read a picture saved in Access DB as a OLE object in a PictureBox in a C# windows Application.</p>
  
  <p>The code that does this is presented below:</p>
  
  <pre><code>        string connString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Rajesh\SampleDB_2003.mdb;";
          OleDbConnection oConn = new OleDbConnection(connString);
          oConn.Open();
          string commandString = "select * from employee where id = " + id + "";
          OleDbCommand oCmd = new OleDbCommand(commandString, oConn);
          OleDbDataReader oReader = oCmd.ExecuteReader(CommandBehavior.SequentialAccess);
  
          while (oReader.Read())
          {
              txtID.Text = ((int)oReader.GetValue(0)).ToString();
              txtName.Text = (string)oReader.GetValue(1);
              txtAge.Text = ((int)oReader.GetValue(2)).ToString();
              txtType.Text = (string)oReader.GetValue(3);
              byte[] imageBytes = (byte[])oReader.GetValue(4);
  
              MemoryStream ms = new MemoryStream();
              ms.Write(imageBytes, 0, imageBytes.Length);
              Bitmap bmp = new Bitmap(ms);
              pbPassport.Image = bmp;
          }
  </code></pre>
  
  <p>When I execute the above code, an 'Parameter is not valid' exception is thrown at the line:</p>
  
  <pre><code>Bitmap bmp = new Bitmap(ms)
  </code></pre>
  
  <p>From the exception message, it is clear that 'ms' is in a format that is not recognisable. Any suggestion to get past this?</p>
