What is the event appropriate to count the items in a DataGrid?

I have a drag and drop target datagrid.  I need to count the number of items is in this grid, every time something fell.

I use the dragDrop event to trigger a manager who gets the length of the data provider data grid.

However, when the first item is deleted, the dataprovider is null.

When the second element is removed from the dataprovider.length is 1; Although there are 2 products.

And each subsequent, the length is less than it should be.

Why is this?  If it is not updated properly is a different event should I link?

In the dragAndDrop Manager to try to use a method callLater to call the online account manager.

In this way the dragNDrop can complete until after the count.

You can also try the dragComplete Manager.  This is generally where any cleanup is performed.

  • What is the fastest method producer consumer. Queue, RT-FIFO, event

    Hi all

    Another question completed for the pro:

    I recently inherited the labview code that uses RT-FIFO for the transfer mechanism in the architecture of the producer consumer.

    The code was first written in 3-4 years and is currently in LV8.6. It is possible that the reasons for the architectural decision no longer exists.

    I am qualified using a producer consumer queued architecture,

    I understand the RT-FIFO Architecture.

    I started using an architecture based on events from the user.

    (I have attached samples of each)

    I also see the existence of a priority queue

    Each method has its own capabilities and gaps, that hand, nobody knows the relative performance of each method.

    (Assuming that the only process)

    I would expect RT-FIFO to be faster, there seems to be a version of low characteristic of a standard queue.

    What is the perfornace hit to use a coding user-friendly queue more

    RT-FIFO description talks about commications between the time-critical and lower priority threads.

    Until today, I thought that the queues had the same capacity.

    I've included an event method that I commonly use for review by peers and help from other users...

    It allows to:

    1. several producers with different types of data

    2. process 37 production order.

    3 allows asynchronous verification of functional notifiers such as stop, start and abort.

    4. in a system not real-time, it can include interactions of façade.

    What I do not understand on this subject, that's what are overhead or thread priority changes that may occur using this architecture (it solves a lot of problems for me).

    Thanks in advance,

    Hi Timmar,

    Here's a KB article on some frequently asked questions about the RT FIFO: http://digital.ni.com/public.nsf/allkb/7AE7075AF1B2C58486256AED006A029F?OpenDocument

    The more relevant question is #4, I posted below.

    What is the difference between RT FIFO and queues? 
    Functionally, RT FIFO and LabVIEW queues are two pads of first in, first out. However, here are the main differences between them:

    • RT FIFOs run deterministically in LabVIEW and evanescent code queues are not. This comes from the fact that queues use block calls during read/write to the resource shared, while RT FIFOs use non-blocking calls.
    • RT FIFO are fixed size while queues develop when items are added to them.
    • RT FIFOs will execute the code, even if there are input errors. They can (and will) produce new errors and spread the existing errors.
    • Queues work with any type of data, while the data types that can be used with RT FIFOs are limited. Generally any type of data involving allocations of extra memory can be used with RT FIFOs to preserve determinism.

  • What is the event when back to summon the Manager

    Hi, I use Invoke Manager to play the video

    What is the event when the invoke handler is close / back-> for my application.

    (I want to analyze how long this user read this video)

    Thank you

    I do not know what past all I KNOW the app called is not informed of which invokes this past that stage of the initial call, therefore no mechanism is a reminder when the application is closed.

    Obviously if you wrote the video player yourself you could invoke back or set up signs saying closed process.

  • What is the difference between Count (*) and Count (1)?

    Hello

    can you please what is the difference between Count (*) and Count (1)?

    I saw that Count (*), Count (1), Count (2)... etc return values from a table. Is there an exact difference between them?

    Have you read the forum space FAQ? I'm sure that you don't have because it is answered there.

    It is also answered via Google.

    The short answer is: there is no difference, unless you use count (1), count (2), etc. instead of count (*) it makes you look like an amateur.

    See that both give the same time

    Do you really think the 100th's of a second it takes 6 rows from counting will truly representative of the difference it takes actually?

    Such a small data set cannot possibly show no difference to these larger units of time (in the calculation of terms where we have millions of instructions per second in lieu)

    As the link to the FAQ provided in the response of Anton (first response on this thread) Watch, count (1) and count (*) are essentially the same, except that count (1) actually get re-written by the query re - write the step of the optimization to make it count (*).

    Generally 'count (*)' makes more sense language, because it reads like "count" while "count (1)" reads as "count we ', which does not have as much good sense when you actually count all.

  • I want to rename and move files from a shoot 5 d. I would like to use the functionality of the increment to count, but since I have to get out of each file to the following file, it starts again at 1. What is the best way to do it?

    I want to rename and move files from a shoot 5 d on a new drive. I would like to use the functionality of the increment to count, but since I have to get out of each file to the following file, it starts again at 1. What is the best way to do it?

    HI -.

    As a prelude to 2014.0, we have added a feature allowing you to choose what number to start the increment of.  Look in the section ingest Rename dialog and change your preset. When you click the button, you should see the option "Custom Auto Increment". This will allow you to choose what number to start on.  We've also added a few newspapers to try to remember where let prelude last successfully interfere the operation by using this option. So, in theory, to remember the number for you. But if it isn't (maybe you want multiple kickoff ingested at the same time) you can always manually set the number to start with.

    Check that out and let me know how it works for you.

    Kind regards

    What is customized event triggered in the OPA.

    I heard that, at the time of the training online OPA in last week.

    A custom event is a way to write a rule that will send a signal. When executing time event listeners can be attached to the motor of the OPA, and a custom event can be used as a way to signal that something should happen.

    For Documentation on writing a raiseevent rule see rules of use to trigger external software applications in modeling of political Oracle Help.
