  Feb 08, 2013 07:08 AM|LINK

  Hi,

  I work with Morena 6 scan java library and must to Handle POST operation with img/jpeg content: Here how to send data:

   

  private class UploadImageAction extends AbstractAction implements Runnable
      { UploadImageAction()
        { super("upload to server");
        }
      
        public void actionPerformed(ActionEvent event)
        { new Thread(this).start();
        }
  
        public synchronized void run()
        { try
          { status.setText("Working ...");
            Image image=selected.getImage();
            ByteArrayOutputStream tmp=new ByteArrayOutputStream();
            BufferedImage bufferedImage=new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_INT_RGB);
            bufferedImage.createGraphics().drawImage(image, 0, 0, null);
            ImageIO.write(bufferedImage, "jpg", tmp);
            tmp.close();
            int contentLength=tmp.size();
            if (contentLength>1024*1024)
              throw new Exception("Image is too big to upload");
            URL uploadURL=new URL(documentBase, "upload.php");
            HttpURLConnection connection=(HttpURLConnection)uploadURL.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setUseCaches(false);
            connection.setDefaultUseCaches(false);
            connection.setRequestProperty("content-type", "img/jpeg");
            connection.setRequestProperty("content-length", String.valueOf(contentLength));
            OutputStream out=connection.getOutputStream();
            out.write(tmp.toByteArray());
            out.close();
            InputStream in=connection.getInputStream();
            int c;
            while ((c=in.read())!=-1)
              System.err.write(c);
            in.close();
            URL imageURL=new URL(documentBase, connection.getHeaderField("file-name"));
            status.setText("Done - image is uploaded to "+imageURL+" (for at least 5 minutes) ...");
          }
          catch (Throwable exception)
          { JOptionPane.showMessageDialog(MainPanel.this, exception.toString(), "Error", JOptionPane.ERROR_MESSAGE);
            exception.printStackTrace();
            status.setText("Failed, try again ...");
          }
        }
  
        public boolean isEnabled()
        { return hasServer && selected != null;
        }
      }

  in PHP it is done by:

  <?PHP
    $dh  = opendir(".");
  	while (false !== ($filename = readdir($dh)))
  	{ $dc[] = $filename;
  	}
    foreach($dc as $f)
    { if (substr($f, 0, 4)=="img_")
        if (filectime($f)<time()-5*60)
          unlink($f);
    }
    $fn="img_".time().".jpg";
  	$fp=fopen($fn,"w");
  	fwrite($fp, $HTTP_RAW_POST_DATA);
  	fclose($fp);
  	header("file-name: ".$fn);
  ?>
  

  I am trying do do same as PHP with ASP.NET. Can someone help to translate this PHP code in ASP.NET?
