  • How to listen out for a stream of data coming from (web)server

    Hello
    I have an applet that connects to a server (same location as web server) and connects to a server on a socket. This all works fine for sending commands to this server. But the server can send data to the client at any moment in time. So how do I listen out for the activity? do I launch a separate thread that sits listening for incoming data?
    What is the way to do it?

    How do you delete [empty] a single file or folder from "Trash"?
    Can you "securely delete" just 1 item?

    A dangerous and incorrect shell command has been posted in this thread.
    NEVER empty the Trash in the shell (Terminal.) NEVER put anything in the Trash unless you intend to delete it immediately. If you do put something in the Trash and change your mind about deleting it, move it out or use the Put Back contextual menu item. Then empty the remaining items in the Trash as usual.

    How to remove the old email address that was hacked from my iCloud account when iCloud won't let me?
    Pretty much the the email that I used (but didn't verify) to create my iCloud account was hacked and now I can't remove it from my iCloud account due to the iCloud password also being changed by the same person and the fact I had "Find my iPhone" app on my phone also??? I had to change my iTunes email as well but that was far easier so yeah :S.
    Please help. I live in NZ, out in the country, so reception is rare and so is getting into the nearest town that has an Apple Store.
    Thanks

    If you truly change your existing Apple ID's email address to a new email address, follow these instructions: iOS 7: If you're asked for the password to your previous Apple ID when signing out of iCloud
    If you created a whole new Apple Account because you couldn't access the old one after being hacked, you will need to contact the Apple Account Security Team. Apple ID: Contacting Apple for help with Apple ID account security

  • How to store the data coming from network analyser into a text or excel file

    Hii everyone
    I'm using Agilent 8719ET network analyser and wish to store the data coming from netowrk analyser into a text file/ excel file.
    Presently I'm able to get the data on Labview graph using GPIB . Can anyone suggest how to go ahead after collect data sub vi. How can the data be stored into a file apart from showing on the graph?
    Attached is the vi for kind consideration...
    Looking for help

    First let me say that your code really looks pretty good. The data handling could be made more efficient by calculating the number of datapoints that are going to be in the completed dataset and preallocating the entire array -- but depending upon your answer to my questions, the logic in the lower shift register may be going away - so we won't worry about that right now.
    The thing I need to know before addressing the data storage question is: Each time you call "Collect and Display Data.vi", how many element are in the array? Are you reading single data points, or a group of data? (BTW: if the answer to that question is obvious based on the way the other VIs are setup, I don't have the drivers so I can't tell what the setup values are.) Second, how fast does the loop iterate? Are we talking msec per loop?, seconds? fortnights?
    The issues here are two-fold: how much data? and how fast is it coming? The answer to these will tell you how to save the data.

  • How to insert data coming from 2 different file adapters in to one DB adapt

    Hi
    i want insert data in to database containing two diffferent tables, so i imported tables in to DB adapter by creating relation ships.But, data for two tables are in xml format & two are in different locations.So, i used 2 file adapters to get data from 2 different & i used BPEL(Define service later) Service. now in bpel i used receive activity to receive one file adapter data ( i checked create instance in receive) then used transform activiy for tranformation & finally invoke activity to invoke DB adapteer........similarly i repeated sequetially to 2 file adapter, by keeping 2nd receive(no need to check create instance) next to invoke.*Problem is after deployment finished only data coming from 1st receive is inserting to the table...& 2 nd receive not working it showing as Pending & showing as Asynchronus Call back inte console*
    I configured all the adapters perfectly..........Can any one can help me how to Commit 2 nd receive to insert data in the 2nd table
    Regards,
    jay

    Thank u both for ur replay.........
    I am doing this in 11g there is no problem regarding transform activity.
    My requirement is
    two different files from two different folders in a drive & we can't use one file adapter bcoz both have different columns(only few are common columns) so we use two different xsd's .So, i am using two file adapters to insert in database having two different tables with respect to two different files data coming from two file adapters. i am using one DB adapter to insert bcoz both tables are in same database with relationships & i used BPEL(define service later) .
    NOW PLEASE SUGGEST ME THE FLOW IN BPEL TO INSERT BOTH FILES IN THERE RESPECTIVE TABLES IN DATABASE.
    The flow i did 1st file adater--->receive--->transform---->invoke----->DB adapter.....Then again repeating this as keeping 2nd receive below 1st invoke
    2nd file adapter-------->2nd receive---->2nd invoke------>same DB adapter
    MY problem is only data coming from 1st process is inserting & 2nd one is not working as i discussed earlier........I USED READ FILE OPTION, UNCHECKED DELETE FILES OPTION & SET DIFFERENT POLLING FREQUENCY FOR BOTH FILE ADAPTERS.
    I tried to set correlation but it is not working & later tried i kept non-blocking invoke as TRUE in DB adapter also didn't work...........also i tried this transaction property in bpel component _<property name="bpel.config.transaction"_
    many="false" type="xs:string">required / requiresNew</property>...............BUT NO CHANGE...........

  • How can i use an ao card (pci 6723) to output data and to trigger an ai o acquire the data coming from the ao card?card (pci 6254) t

    Hello
    I am trying to perform AO (pci 6723) and to trigger my AO card (pci
    6254) to read the data coming from the AO card. I am using LV7,1,
    win2000.
    Is an RTSI cable necessary or I can connect the trigger signals externally ?
    I am using the LV example " multi function - synch ai-ao.vi" but i can't for some reason configure the trigger lines.
    thank you in advance for your time.
    Yiannis

    Hello Yiannis,
    If I understand you correctly, you want to synchronize your analog input and analog output that are started by a trigger on the analog input board. If you don't want to use the RTSI lines, your best bet is to export the AI Sample Clock and then read it in to the AO board. There is an example on ni.com called DAQmx - Synchronized AIAO Shared Clock. It appears to be having techincal issues so I have attached the example below. To export ai/sampleclock, use DAQmx Export Signal.vi after Get Terminal Name with Device Prefix.vi. Export Sample Clock to PFI3 (There are only connections between the sample clock and PCI3/4/8/9). Connect PFI3 on your AI board to PFI0 on your AO board (with a wire). Then change the source for the AO Timing.vi to Devx/PFI0. If you want to do triggering, stick the DAQmx Trigger.vi between the Timing property node and the DAQmx Start.vi on the AI task. I have shown how to do this in the modified version below. Please take a look at it and let me know if you have any questions. If you still get an error please take a screenshot of it and post to the forum. Have a great day!
    Sincerely,
    Marni S.

  • How to find out the URL of the user coming from?

    Hi folks,
    From the HttpServletRequest, is there a way to find out the URL of the user coming from?
    Thanks in advance!
    Billy

    It is strange. The link is on a different http site eg. http://www.othersite.com. The link is pointing https://www,mysite.com/index.html. I put the alert(document.referer) on the index.html. Using FireFox will show the alert http://www.othersite.com every time. However, on IE, the first time is empty. The second time I click on the link, it will show http://www.othersite.com. Very consistent.

  • How can you tell where a call is actually coming from not just where the phone was activated?

    me and my wife check our account and we are wondering how we can find out where our son is calling from it only puts the town where we originally signed up with Verizon,help please!!!!

    If this is a Microsoft based phone AND you have location awareness turned on AND they have this phone tied to a Microsoft account AND you have access to all of the account information, then there is a Microsoft web site that will show you the current location of the phone.  Otherwise MrGecko is pretty much dead on.  You would have to have an app on the phone, or pay Verizon more money to give you the location.

  • How to figure out where non-deallocated objects are coming from?

    When running the instruments program and checking the "net" box on the left side, is see that as I run my program the counts for various object types keep increasing. As my program is a simple one where the user is going from page to page, I will assume that these increases are the mark of a memory leak. The system is not detecting these as leaks but certainly my block count should stay more or less constant. I see that I am leaking some CGImage blocks; how do I find out where in the code these blocks are coming from; how to I go the line of code that create a particular block?

    Instruments has plug-in tools. Which tool are you working with?

  • How to remove the empty Top Navigation space on a main publishing page.

    What I did so far was to use snippet into the page (using Script editor) to do the following:
    a. Disable Top Navigation bar
    b. Disable the Title
    c. Remove the left nav bar
    d. Remove the search box on top right
    here is the code used so far:
    <style type="text/css">
    #titleAreaBox {
    display: none;
    #sideNavBox {
    display: none;
    #contentBox {
    margin-
    .ms-fullscreenmode #contentBox
        margin-
    h1.ms-core-pageTitle { display: none; } /* hide page title next to the logo */
    </style>
    As you see in the following picture, there is lot of space left at the Top Navigation area and I want it to go away, at least the most of it. How do I do that using the snippet code? Is there any other way round? I am not a web designer, so please keep it
    clean and simple when you try to explain to me what to do.

    Hi,
    From your description:
    a. Disable Top Navigation bar
    b. Disable the Title
    c. Remove the left nav bar
    d. Remove the search box on top right
    Here is the CSS code:
    <style>
    #sideNavBox { display: none }
    #contentBox { margin-left: 20px }
    .ms-core-navigation {display: none }
    h1.ms-core-pageTitle { display: none }
    #searchInputBox { display: none }

  • How to remove the empty lines in the generated XML?

    Hi, XML/JDOM experts,
    I used JDOM to generate an XML file in my exercise of comparing two xml files.
    I used a lot of times addContent()...
    The resuting xml is fine for its contents.
    But I don't like so many empty lines (or carriage return).
    Would you help to refine the result?
    Best regards,
    AG
    Sample results:
    <li delta:property="Modified">
    <code delta:property="Modified">
    <delta:NewValue>foreignObject</delta:NewValue>
    <delta:OldValue>text</delta:OldValue>
    </code>
    <svg xmlns="http://www.w3.org/2000/svg" width="6cm" height="45px" delta:property="Removed">
    <rect y="0" x="27px" width="110px" height="45px" style="fill: #C1FFFF" />
    <foreignObject width="120px" y="0" x="20px">
    <div xmlns="http://www.w3.org/1999/xhtml">

    <li>First item</li>

    text in SVG
    </text>
    </svg>
    </li>

    The solution is to add
    outputter.setTrimAllWhite(true);
    Below is the sample code.
         FileOutputStream out = new FileOutputStream("delta.xml");
         XMLOutputter outputter = new XMLOutputter(" ", true, "UTF-8");
         outputter.setTrimAllWhite(true);
         outputter.output(doc1, out);
         out.close();

  • How to remove an empty row after a table anchor?

    We are using FrameMaker 12 on a Windows 7 (64 bit) platform.
    I am working my way down a chapter of training content. I am halfway down the chapter, and—as fate would have it—I need to start a table at the top of a page.
    When I insert a table (with a caption/title at the top), FM creates an anchor at the top of the page. The space to the right of the anchor is a blank line.  I actually want the table to start at the top of the page without the blank line to the right of the anchor.
    This is what I tried, with the results:
    I put the cursor after the anchor, and press Delete.
    Result: The text *below* the table is brought up above the table.
    I put the cursor after the last bit of text on the previous page, and press Delete.
    Result: The paragraph on the previous page moves down to the next page on top of the table, leaving a large blank space on the previous page.
    I change the Start option (on Table Designer) to Top of Column (or Top of Page).
    Result: FM leaves the anchor where it was, moves the table down to the next page, and leaves a totally empty page where the table used to be.
    Is there any way to just move the table up so that it is on the same line as the anchor?
    (And as a tool design issue, is there EVER a reason why a content developer would want an entire blank line above of a table?)
    Thank you in advance,
    Tim

    I've always thought it strange that FrameMaker doesn't properly butt
    tables against the top of a column by default. Here's how to make tables
    do it.
    1. First, in the Table Designer, on the Basic tab, set Spacing Above to
    a negative number, such as -2.0 pt, for the table. (You probably want to
    update all of your table styles to use this number by default.)
    2. Create an anchor paragraph style to hold tables, perhaps naming it
    TableAnchor. In the Paragraph Designer, on the Basic tab, set Spacing
    Below Pgf to the same negative number, such as -2.0 pt, for this
    paragraph style and select the "Fixed" checkbox. On the Default Font
    tab, set the font to the same number, but positive-- such as 2.0 pt.
    3. Now, whenever you want to insert a table, first insert a TableAnchor
    paragraph to hold the table, then insert  your table. The table will not
    only fit properly against the top of a column, but should also look
    better when it follows text in a column.
    NOTE: Anywhere I've used 2.0 or -2.0, you can use any number you want,
    just be sure to get the signs right and use the same number in all three
    places. Some people use 12.0 pt and -12.0 pt, for example.
