Hi All
I have an error for retrieving images from Ms Access like this:
<<Parameters is not valid.>>

Although I copy the code from practical sample but I don't understand this Error:

private void button1_Click(object sender, EventArgs e)
    {
        OleDbConnection myConnection = new OleDbConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

        myConnection.Open();
        OleDbCommand cmd = new OleDbCommand("select * from [Images] where ID=1", myConnection);
        OleDbDataAdapter da = new OleDbDataAdapter(cmd);
        DataTable dt = new DataTable();
        da.Fill(dt);

        if (dt.Rows.Count > 0)
        {
            if (dt.Rows[0]["AImage"] != DBNull.Value)
            {
                pictureBox.Image = ByteArrayToImage((Byte[])dt.Rows[0]["AImage"]);
            }
        }
        myConnection.Close();   

    }

    Bitmap ByteArrayToImage(byte[] b)
    {
        MemoryStream ms = new MemoryStream();
        byte[] pData = b;
        ms.Write(pData, 0, Convert.ToInt32(pData.Length));
        Bitmap bm = new Bitmap(ms, false);
        ms.Dispose();
        return bm;
    }

The error has been shown in

Bitmap bm = new Bitmap(ms, false);
