What is the best method to refresh the content of the screen (possibly push refresh)?

We use Coldfusion 9.0, and our question is simple.  We were asked to do some screens display to set up a schedule of events.  So, we created a Publisher backend HTML fast and made the client refresh every 30 seconds with meta refresh that displays the screen that is published.  Wonderful œuvres.  A change is made, the screens to be quickly updated in 30 seconds or less.

This weekend we had an update put the server to this plate up a larger problem.  Update temporarily stop the Web server and which caused the display to the standard site is not reachable (diagnose connection, etc.).  At this time where the discount is killed, display screens are dead in the water until someone knocks f - 5.  Makes us think that whenever we have any operation of blip, the screens will have to be touched.  It is a small project, we wanted something simple and we got it.  I'm afraid that now we just created a situation of surveillance techsupport involuntarily.

Which brings me to the real issue.  What is the best practice to do?  After doing a google search, it seems to be all sorts of directions to go.  I don't want a complex solution because the decision not to outsource was based on the speed of a project, it was.  I'm hoping to get some tips on how to make a simple pressure of the HTML to a screen in a Coldfusion environment.

Thanks in advance for any help offered.

Thank you very much for your answers.  I think we're going to depend on the network is stable and organize updates on the server at the time we can monitor screens.  After researching the issue, we found that it is a little more deeper than at first glance.  We found which is a good lead if we go to another direction, or someone else has a similar problem: http://en.wikipedia.org/wiki/Comet _ (programming)

  • A2109 - what is the screen? I guess what no gorilla glass?

    Hello

    I have 2 of A2109 on command.  I was trying to get an iPad, but saw these on sale at Newegg for 229 and decided that I could get one for my wife and one for me for the same price as a single Apple device.  And specifications are superb.  Yes, I'm sure someone will remind me on the screen, but I don't think that that's going to bother me. Which brings me to my question: what covers the screen?  Glass of what that it is special or simply?  I don't expect exotic glass at this price, but I was wondering if there is anything knows what it covers?  Thank you.

    Never mind.  According to this, it's just glass.

  • What is the screen resolution?

    Why can't one find a space to put my password when you are prompted to upgrade adminastrator password?

    Hello

    Where are you that prompts for the password?

    Are you invited to enter the password after your computer comes out of the screen saver?

    When have you started to notice this behavior on your computer?

    If you receive this message when you try to run any application, then your user account may not have the required administrator credentials. In this case, you must change the type of account to the account administrator.

    Change the type of user account
    http://Windows.Microsoft.com/en-us/Windows-Vista/change-a-users-account-type

    Since you mentioned the screen saver, and assuming that you found the password after the computer comes out of the screen saver mode, you will need to disable this option.

    1. open the screen saver settings by clicking the Start button picture of the Start button, clicking Control Panel configuration, appearance and personalization, customization, and then click screen saver.

    2. Unselect/disable the one summary, require the connection box, set a time after which the screen saver throw and then click on apply. (Choose a time-out period that is not long enough for an unauthorized person to use your computer, but not too short that if you are inactive for a while, the screen saver locks your computer.)

    If the fast user switching is turned on, select the On resume, display logon screen check box.

  • Whats with the screen pink flashing when you cancelled your Rhapsody account?

  • What is the right time to call the pushScreen()?

    Hello

    I made a screen that simply indicates "Loading"... "while my app works through its processes. the problem is that the screen never had pushed until after the function when pushScreen() is back. the call looks like this:

    function func() {
    
    //I'm hoping the loading screen would be pushed right here....
    
    app.pushScreen(loadingScreen);
    
    //app does its stuff
    
    return;
    
    //but instead the screen is pushed after func() finishes.
    
    }
    

    what I am doing wrong?

    Thank you

    Edit: I forgot to mention that this function if calling from a menu item, and in fact the menu itself doesn't close until after func() is done. How can I fix it?

    Or, a bit simpler:

    new Thread() {
        public void run() {
            // do the work here
        }
    }.start();
    

    Somewhere in run(), once the work is done, you can call Application.invokeLater (), passing an executable to update the UI with the results. (Alternatively, you can update the user interface of a separate thread by synchronizing on the object returned by Application.getEventLock (), but that is more complicated).

  • Satellite P105-S6114 - gray line vertically on the screen

    Hello

    I'm new to the forum so please excuse me if I look like a novice (because I am).
    I have a Toshiba P105-S6114 that suddenly developed a gray vertical line about 1 inch wide and about 3 inches from the right side of the screen. It seems that if it is washed out. You can not see on white screens but is very sensitive to all other colors. It appears when you start the laptop to search on the net, I think while it is on the screen. What is the screen? or something escapes me?

    Please correct me for false assumptions in my post.

    I started pricing new screens. Locally for installing I got a quote of less than $500.00. I saw on ebay (new) about $280.00 aus replacement screens. Installation I expect about $100.00. If someone knows a cheaper solution, I would be very happy to hear it.

    I saw a screen for a P105-s6062 that appears from the PDF file to be identical to the S6114. It is second hand, but sounds like a viable option. Does anyone know if the screens are identical, including the connections?

    Someone at - it any other suggestions? I'd be happy to hear from someone as the laptop itself is large and I don't really want to get rid of it.

    > It appears when starting the laptop to search on the net, I think while it is on the screen. What is the screen? or something escapes me?
    It might be the screen of laptops, but it could also be a malfunction of the graphics card.
    If you first need to know what's exactly wrong.

    In your case, I recommend you to connect a second external monitor to the laptop.
    Then check if the same vertical lines appears also on external monitor.

    If the same could not be visible on the other display, the chances are high that a graphics card is malfunctioning.

    In this case a replacement of the motherboard would be necessary and this would be a costly affair!

    Anyway, in both cases, I would recommend contacting the ASP in your country.

    Good bye

  • Equium M40X: red lines on the screen

    Maybe my graphic.and so yes anyone with a solution or do I have to disassemble everything this...

    Thank you

    I agree with Richard. There's probably graphics card failure. If the same behavior occurs during the starting procedure, the graphics card must be exchanged. I mean the motherboard together. ;(

    Hi friend

    It's definitely a hardware failure. The question is:

    What is the screen, the display cable or the motherboard.

    You know that you will have to pay for it, but it s on you if you do not want to spend the money for it or just sell it on Ebay and get another machine.

    If I were you I contact some store or a repair service center and ask them a health check of equipment, so you can locate the defective part.

    Welcome them

    P.S.: If you need a link to the closest match. Authorized service center then click on [HERE: http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_whitepaper.jsp?service=EU&WHITEPAPER_ID=0 000000871].

    You really want to change the order of these two instructions - first super.makeMenu and menu.add.

    I guess that your screen extends the screen. If this is the case, the correct way of creation, it would be

    super(new VerticalFieldManager(), Screen.DEFAULT_MENU);
