  • Update database every 30 minutes once

    - by Ravi
    Hi, I am working on C#.Net Windows application with SQL Server 2005. This project i am using ADO.Net Data-service for database maintenance. I am working on industrial automation domain, here data keep on reading more than 8 hours. After reading data from device based on the trigger i have periodically update data to database. for example start reading data on 9.00AM, trigger firing on 9.50AM. Once trigger fire, last 30 minutes(9.20 AM to 9.50AM) data store into data base. After trigger firing keep on reading data from device and store into data base. 10.00AM trigger going to off at time storing data to database has to be stop. Again trigger firing on 11.00AM. Once trigger fire, last 30 minutes(10.30 AM to 11.00AM) data store into data base. After trigger firing keep on reading data from device and store into data base. After 10.00AM trigger not firing means data keep on store locally. Here i don't know until trigger fire keep on reading data where & how to maintain temporarily , After trigger firing, last 30 minutes data how to bring and store into database. I don't know how to achieve it. It would be great if anyone could suggest any idea. Thanks

  • Is it advisable to have non-ascii characters in the URL?

    - by Ravi Gummadi
    We are currently working on a I18N project. I was just wondering what are the complications of having the non-ascii characters in the URL. If its not, what are the alternatives to deal with this problem? EDIT (in response to Maxym's answer): The site is going to be local to specific country and I need not worry about the world wide public accessing this site. I understand that from usability point of view, It is really annoying. What are the other technical problem associated with this?

  • Java: Multithreading & UDP Socket Programming

    - by Ravi
    I am new to multithreading & socket programming in Java. I would like to know what is the best way to implement 2 threads - one for receiving a socket and one for sending a socket. If what I am trying to do sounds absurd, pls let me know why! The code is largely inspired from Sun's tutorials online.I want to use Multicast sockets so that I can work with a multicast group. class server extends Thread { static protected MulticastSocket socket = null; protected BufferedReader in = null; public InetAddress group; private static class receive implements Runnable { public void run() { try { byte[] buf = new byte[256]; DatagramPacket pkt = new DatagramPacket(buf,buf.length); socket.receive(pkt); String received = new String(pkt.getData(),0,pkt.getLength()); System.out.println("From server@" + received); Thread.sleep(1000); } catch (IOException e) { System.out.println("Error:"+e); } catch (InterruptedException e) { System.out.println("Error:"+e); } } } public server() throws IOException { super("server"); socket = new MulticastSocket(4446); group = InetAddress.getByName("239.231.12.3"); socket.joinGroup(group); } public void run() { while(1>0) { try { byte[] buf = new byte[256]; DatagramPacket pkt = new DatagramPacket(buf,buf.length); //String msg = reader.readLine(); String pid = ManagementFactory.getRuntimeMXBean().getName(); buf = pid.getBytes(); pkt = new DatagramPacket(buf,buf.length,group,4446); socket.send(pkt); Thread t = new Thread(new receive()); t.start(); while(t.isAlive()) { t.join(1000); } sleep(1); } catch (IOException e) { System.out.println("Error:"+e); } catch (InterruptedException e) { System.out.println("Error:"+e); } } //socket.close(); } public static void main(String[] args) throws IOException { new server().start(); //System.out.println("Hello"); } }

  • HTML tag for identifying text

    - by ravi
    I am not very much familiar with HTML programming. If we look at the source code of a page, then we can see what are the HTML tags for which texts and so. It is the case that there is group or class of HTML tags which is used for purpose such that it can be used for main text or so. I mean like '<\input type="radio" name="option"' this tag says that there will a radio button, similar can be make a group of HTML tags such that it consist of text part, which means we look at the tag and not at the content and can say that in between startTag and endTag we have text.

  • Can a variable like 'int' be considered a primitive/fundamental data structure?

    - by Ravi Gupta
    A rough definition of a data structure is that it allows you to store data and apply a set of operations on that data while preserving consistency of data before and after the operation. However some people insist that a primitive variable like 'int' can also be considered as a data structure. I get that part where it allows you to store data but I guess the operation part is missing. Primitive variables don't have operations attached to them. So I feel that unless you have a set of operations defined and attached to it you cannot call it a data structure. 'int' doesn't have any operation attached to it, it can be operated upon with a set of generic operators. Please advise if I got something wrong here.
