How to dump in the event of a buffer running

I'm looking for some effective ideas on a dump of the event.  At this moment I have a basic data logger.  It takes data at 100 Hz and ignores all but the last data point for a given period. for example: a sample every two seconds, not two cents.  I await with discontinuity record events without sacrificing the base datalog feature.

I think I want the channels of interest to be stored in a buffer running at the full 100 Hz.  Maybe a queue with loss or a specified length running table?  Another concern is how add these data after the datalog colums base but not the datalog out of queue on the possible event data? Is there a difference between putting the structure of the event around queue item in the process loop and place it around the dequeue element in the loop of datalog?  I'm relatively new to labview so if I make it work, it will probably not answer 'best practice '.   I'm going to start playing with the code, but the high speed, low drag answers are really appreciated.

Good news! This works.  I set the logic of works so that it catches small interruptions.  It took some time, but it works.  I tried a local variable to receive the data, but it didn't intercept the fast events.  I had to put it in the Q and split in the loop of logging. Another thing is the case adding the table structure.  the first iteration feeds the first element in the top of the table to append, so the timestamp is preserved. all subsequent iterations shift the new item to the following location, make room for the table attached to slot 1.

  • How can I disable the Agent updates from HP running?

    HP pavilion D4100Y

    Windows XP SP2 or 3 (not sure)

    No error message

    No recent changes

    Problem: The program "HP updates Agent" run frequently and on no particular schedule, certainly not the one I chose.  He takes over my computer for hours and using most of the CPU, fluctuating between 13% and 87% to 1 etc.3% at 6%, etc.. The computer crashes and I can not use it for something else. On the HP updates screen, I put updates on 'NEVER', but that did not work.  The programs always run. In the Windows Task Manager window, the program is called "Agent updates from HP".

    I find nothing on this problem in the base of support.

    How can I disable the Agent updates from HP running?

    Select your Start button, in the search box type 'msconfig' then msconfig.exe under programs.

    Look under the tabs "Services" and "Boot". Uncheck update HP agent, select 'Apply' and close.

  • How to aggregate all the events which lead to the occurrence of a complex event?

    Hello

    Is it possible to aggregate all of the events that lead to the occurrence of a complex event in this complex event?

    Let's say we have six singles events
    id    amount    groupId
    1     1         1 
    2     0         2 
    3     1         1
    4     1         2
    5     2         2
    6     1         1
    The definition of complex event is
    select sum(amount), groupId from myStream[range 20 seconds slide 20 seconds] group by groupId having sum(amount) = 3
    Consider that I have the following class for my complex event:
    public class ComplexEvent {
        private int groupId;
        private int amount;
        private List<SimpleEvent> events;
    
        // getters and setters
        ...
    }
    Is it possible to have two complex events:
    ComplexEvent1 = {groupId=1, amount=3, events=[{id=1, amount=1, groupId=1}, {id=3, amount=1, groupId=1}, {id=6, amount=1, groupId=1}]}
    ComplexEvent2 = {groupId=2, amount=3, events=[{id=2, amount=0, groupId=2}, {id=4, amount=1, groupId=2}, {id=5, amount=2, groupId=2}]}
    How can achieve us?

    Hello

    I blogged an example of solution to this type of use case since it is a common scenario in the CEP applications:

    http://blogs.Oracle.com/CEP/2010/08/enriching_complex_events_with.html

    There are not currently out-of-the-box support for the events of paging to disk storage. If you really more events that can fit into the Java heap, you can try persistent events of the database or a data grid, such that the consistency and by linking to the database or the cache to create the event complex containing the events of causality.

    Another approach is to horizontally partition the flow of incoming events on multiple servers.

    Kind regards

  • How to check if the event in actionscript is initiated or not?

    Okay, so I played with event management in action script two or three times, but I came across this situation, where I need to check if the event in the actionscript code is already called or not. looks like the code snippet below:

    currentTrajectory = new collection ArrayCollection (event.result as Array);

    var _multiTrajectoryEvent:MultiTrajectoriesEvent;

    If (_multiTrajectoryEvent is initialized) / / that's where I need to check

    {

    _multiTrajectoryEvent = new MultiTrajectoriesEvent (MultiTrajectoriesEvent.DRAW_AUTO_TRAJ);

    }

    //raise an event to

    Swiz.dispatchEvent (_multiTrajectoryEvent);

    }

    Whenever I get the result of the database event and I add result to arraycollection of event collection. However, I want to make sure that this event object is created only if it has not been initialized before in order to have the previous value of the table collection event isnide.

    Check if the event object is null does not work and if the event is not initialized, I can't check its property bubble as well...

    I would appreciate your quick thoughts for the same

    Thank you very much

    Generally, people reuse events. I've never seen a recycled event object, potentially, it could lead to side effects if any code handling the event maintains a reference to the event.

    My advice not to recycle the event objects. They should be garbage collected when they are no longer used. Create a new each time. Your custom event has no payload, so I'm really not point of needing to reuse. Any use not made of currentTrajectory.

  • How seeds Cache using the Event Table of the poll

    Hello Experts

    I have configured the Event Table of the poll in my PC
    Steps to follow:
    (1) table created using SAEPT. Oracle.SQL scheme in 10g
    (2) any SAEPT. Oracle.SQL by creating a new connection pool in the physical layer
    (3) configured in repository - tools - utility - OBI event Polling tables by selecting SAEPT. Oracle.SQL and gave 15 min in the polling frequency
    (4) inserted data in SAEPT. Oracle.SQL
    (5) NQserver.log checked after the time of the poll which is 15 minutes. NQserver.log was not getting updated or details about the event that occurred.

    You think that I missed a few steps in the configuration of EFA, if so... Please help me I need to implement on the client machine soon.

    Enjoy your time guys.

    As much as I know the vote event tables are used to purge the cache automatically. It is not used to start the cache.
    If you want to start the cache, the ibots use or you do like a program...

  • How autoinitialize controls to the value by default to run?

    Hi all

    I am trying to initialize the default values to controls just after the run button is hit. This only works if the control is loaded with default values before running. I am a frame and any kind of help will be really appreciated.

    Your VI is stupid. You must understand the data flow. Not sure if the control is going to write to the indicator, first, or if the case statement will run. What finally will you do with your program. I hope that you have some kind of while loop (do NOT use the continuous run button). Then the method would be just outside the loop and don't run once - no need an instruction box. You could also place inside the first State of a state machine.

  • How can we save the event when Photoshop is stopped?

    Hi all!!

    I have to perform actions on the record of events of a document. I had no problem doing the same thing. But, in the course of the different tests save event trigger scenarios, I fell on the situation in which a document without title is open and the user closes Photoshop. At this point, Photoshop prompts the message "do you want to save the document? Regardless of the user's selection ('Yes' / 'No'), the plugin is unable to obtain registration event, perhaps due to the termination of the application. I get the message of kSPInterfaceShutdownSelector directly. Don't stop to save event reminder.

    How can I make sure that my save event callback is executed each time a user saves a document?

    Thank you!

    You must analyze the close event descriptor. Locate the key keySaving

  • How to get to the event with a click on send in the Messages application

    Hi all

    We write code in my application to get the content (, object, body.. data) while clicking on "Send" menuitem in the application "Messages"...

    Or can show our own guest while clicking 'Send' element in the 'Messages' application to copy the details of the e-mail (messages) in my application...

    Thanks in advance...

    You can place an ApplicationMenuItem on the program of Messages, but I don't think that's what you're looking for.

    You can also try adding a FolderListener in the mail store, then you get to announce to any e-mail message hit the folder. The subject of the message has a "isInbound()" method that will tell you if the message is incoming or outgoing.

    See the documentation for the API to Store, FolderListener, Message, and FolderEvent.

  • How can I prevent the error "Firefox is already running" message while trying to open the links and FF has already been opened by a symbolic link?

    I use symbolic links and shortcuts of programs as a way to easily open different Firefox profiles IE. one for casual/personal use and the other for work. It works well, but I get the error message "Firefox is already running, but is not responding" if I try to open external links with FF as my default browser. FF is actually open and works very well, but I guess that it does not recognize this fact due to how I started the beginning of the process.

    I could not add executables symbolically related to the component of default program. Is there a way to get around this error or another way to solve this problem?

    The solution to the question below, it's what I use to open the different profiles of FF.

  • How can I preserve the history of Start Menu run?

    In Windows XP SP3, the list of recently used commands via "Start/run" is somehow erased every day and I would have preferred to select a command, that I recently used instead of having to retype.

    Thanks Jim. I tried to make sure that no programs are compensation history and I'm not clear manually. RegMon is a free download? I don't know how to create .reg files. Regarding adding these commands to my quick launch or in a folder on the root of the Start Menu, I see that as something that I probably could do.

  • How can I change the programs that my computer runs at startup... as when I first cut it on all programs that just automaticlly opens

    When I cut on my computer it starts a program called frost wire and it freezes I want to remove where it starts automaticlly and just start up when I open

    Hello

    FrostWire is a BitTorrent software or any bit torrent software can be dangerous to use that you can end up with a Malware infected computer.

    As your computer freezes because of this, I would like to download Malwarebytes anti-malware update and scan of Malware:

    You can manage through Windows Defender startup programs.

    But if you use McAfee, Norton, AVG and MSE, etc as an Anti Virus they disable Defender, which is the best thing for them to do.

    There are a couple of other ways to manage startup programs:

    Here's how to use MSCONFIG in Windows Vista to disable some unnecessary programs that load automatically at startup. Disabling these programs will help your computer boot faster and crash less.

    Alternatively, you can use this free Autoruns program:

    This utility, which has a knowledge of auto-starting locations of any startup monitor, shows you what programs configured to run at system startup or login and that the entries in the order of processing windows. These programs include those in your startup folder, Run, RunOnce, and other registry keys. You can configure Autoruns to show other locations, including Explorer shell, toolbar extensions, helper objects to the browser, Winlogon notifications, auto and many start-up services even more. Autoruns goes way beyond the MSConfig utility bundled with Windows Me and XP.

    Autoruns' hide signed Microsoft entries allows you to zoom in on images of automatic start of third parties who have been added to your system and it has support for looking at images of Autostart configured for other accounts configured on a system. A command-line equivalent that can display in format CSV, Autorunsc is also included in the download package.

    You may be surprised how many executables are launched automatically!

    And some programs under Tools > Options give you the choice to know if they start when Windows starts, or not.
