strQuery = "select * from test_drawing where s_no=3";
           objCmd = new OleDbCommand(strQuery, objConn);
           dr = objCmd.ExecuteReader();
           if (dr.Read())
           {
               write = (byte[])dr[1];
           }
           dr.Close();
           //if (!File.Exists(path + "\\drawing.pdf"))
           //{
           //    File.Create(path + "\\drawing.pdf");
           //    filename = path + "\\drawing.pdf";
           //}
           //else
           //{
           //    File.Delete(path + "\\drawing.pdf");
           //    File.Create(path + "\\drawing.pdf");
           //    filename = path + "drawing.pdf";
           //}
           filename = path + "drawing.pdf";
           using (FileStream
          fileStream = new FileStream(filename, FileMode.Create))
           {
               // Write the data to the file, byte by byte.
               for (int i = 0; i < write.Length; i++)
               {
                   fileStream.WriteByte(write[i]);
               }

               // Set the stream position to the beginning of the file.
               fileStream.Seek(0, SeekOrigin.Begin);

               // Read and verify the data.
               for (int i = 0; i < fileStream.Length; i++)
               {
                   if (write[i] != fileStream.ReadByte())
                   {
                       Console.WriteLine("Error writing data.");
                       return;
                   }
               }
               fileStream.Flush();
               fileStream.Close();
               axAcroPDF1.LoadFile(filename);
           }
