Change of the Structure Persitible

Hi all

I plan on upgrading an application, but it seems that I forgot my class structure can change in the future by adding other objects to it.

Is the best practice to have right holders place in a class?

for example

Settings/public class implements Persistable {}

PlaceHolder1 int

int PlaceHolder2

int placeholder3

..

How should I manage change in format to an upgrade, create a mirror of my old class, read it in the updated application, and then save it in the new structure and save that?

You can use a mutable object, such as the hash table, for your settings.
This allows you to add and remove parameters without the object resulting from the config being incompatible.

  • leads the value change in the structure of the event

    Hello

    Please the the VI attached.

    I would like to know what event triggers when the value true or false of the changes led?

    In the case of structure above the structure of the event, the values of true or false of the led are changed.

    From the change, the analog output for Acquisition Card changes. However, the change event of the value in the structure of the event never fires, I know that I run the Vi with the selected highlight enforcement tool.

    Thank you

    Changing the value in an event structure occurs only if one of the two following situations occurs.

    1. the user who modifies the control on front panel.  That may not happen since these LEDs are indicators and does not control.

    2. the program writes a value of property of the Value indicator/control (signalling) node.  Writing to the terminal of the indicator, or the local control variable / indicator not fire the event.  Given that you do not use value property (signalling) nodes in your program from this moment, won't happen either.

    Note that the value change event is a bit misnamed.  The change event is triggered, even if you do not actually change the data.  So if your LED is currently worth, and you write a True Boolean value for the Value property node (signalling), the event always fires even if you're not technically change the data.

  • Presentation of form data XML - Can change you the structure of nodes?

    Hi guys, I was wondering if there was a way to change the structure of nodes in an xml file [submitted via a form by e-mail], instead of that livecycle creates by default. or is it a case that once you select "submit as: data XML (XML)"-it is out of your hands? "  In the meantime thanks for any help / suggestions. At soon Dyr

    You can create an XML schema and map it to the form fields by creating a data connection (see Help file). In this way you structure the XML into any format you want.

  • How to trigger the value change in the structure of the event

    HII everyone, like the title, how should I trigger the value change event to display a message... Here is my connection... I want to trigger structure of the event to bring up the subvi, when the flame and the led are TRUE State... I have using the node property, but still not able to run event structure... How should I connect? Thank you very much...

    There are several ways you can do. First of all, you need to configure your sub - vi while he does everything you want when you run (in the properties of vi, top most window for example) and to make sure that it closes completely when you're done (when you click on the 'OK' button, for example).

    Spend you need an asynchronous call to the subvi. There are several ways to do so. My favorite one below. You go in the palette under 'Application control' and select a static reference VI. I like this approach because it keeps track of the way subvi for you, as long as the subvi is in the same project. Then, drag the sub - vi on the empty square which will be changes to your sub - vi icon. Then, you connect to an invoke node in the same palette under and select run VI. "Wait, that 's" set to false and the main VI will continue to function after the start of the vi of Sub. Together "Auto Ref" is the best way to go. Otherwise, you will need to follow the sub - vi reference and shut up yourself when you are finished.

  • Consolidation of the changes in the structure of the Group

    When an entity A sells entity B to the C entity in may, the C entity must consolidate the P & L of B of the time of acquisition (May). Also should consolidate A P & L of B until the time of the sale. HFM is set to org by period and uses Active / not active in the management of the property (also tried PCON = 0% / 100%). Consolidation is based on the values of the CDA. When I consolidate can P & L for B er 0 for A, because CDA can is zero. For C P & L for January - may of ter are consolidated in May. This is not correct, but how could I implement the correct application to fix this?

    Published by: user10938694 on November 27, 2009 08:24

    So that the HFM manage cases of mid-year acquisitions and disposals, you must clear the ConsolidateYTD flag. If I say that this change should not affect the application in other respects, this statement does not guarantee success. This is why your concerns about the negative effects this change might have are fair. Examine the copy of the application in a test environment, and then test the modified version before applying the changes to production. The existence of a development/test in parallel to the production environment is still a practice that should not be overlooked.

  • The structure of the table of contents get won't suffer if the structure of output file is changed?

    I used FlashHelp to generate output for a project so the output folder has a structure, now while deploying the server if I make changes in the structure of output file/folder it will affect the "table of contents" or any other characteristic.

    Also, while deploying the o/p in files on the server what needs to be done so that the new custom skin (which i using flash) appears to the help pages for my request, as I call the o/p my request htm files directly by using a script.

    I hope that the explanation I posted is understandable.

    Hi kiki_04 and welcome to the HR community.

    The output of your project files cannot be moved or renamed without breaking the links throughout your project. Any changes made to folders or files MUST be made inside your RoboHelp project. It is best to think of your output in a single file, even if it is not. In other words, your output may be moved between places in its entirety

    In regards to your new skin, it must be imported into your RoboHelp project and specified within your layout of the FlashHelp single source.

  • Reorganize the structure of folder with LR?

    Hello world

    I currently have all the photos on my local drive using this structure, MyPictures\YYYY-MM-JJ. I just got an extra envelope with two discs and I put disks in mirror for backup purposes. I would change the structure of file at YYYY\MM\DD (ex: 2009\12\19). Is it possible to import files in LR to their current path and copy them to the new path based on the date of shooting and have the catalogue LR pointing to the new path for these files?

    If you mean reimport the photos that are already in LR to get the folder structure you want... it's not a good idea, as re-imorting loses a lot of information, including historical edition, Member of the collection. In addition, you lose all your metadata (keywords, captions, etc.), unless you have first LR write these xmp data.

    If the photos have never been imported into LR, the import process can move files in the folders that you want, this option can be selected in the dialog box import LR.

    Let me tell you that my worry about minor changes in the structure of folders seems to miss the big point of the Lightroom library module, which gives you much more powerful tools for organizing your photos as folder name/structure. Just because you change your folder structure does not mean that it is a useful thing to do. With the help of keywords, captions and other metadata will give you something more flexible and powerful than anything you could make by using folders.

  • Structure of the event run only on first change of the value

    Hi all

    I would like to a structure of the event to run only on the first change of value. I currently put to run on the change in the value of a Boolean value. I'm only interested in what happens the first time that the Boolean value changes; However, he changes several times during a single run of my vi. Is it possible to limit the structure of the event so that it runs only on the first change of value? I have attached the relevant part of my VI. Thank you in advance for any help, you will be able to provide.

    Thank you

  • Button value change records in the structure of the event, but does not change appeaance?

    Hello world

    A quick question... I hope someone can answer...

    I have a code that uses a PS button within a structure of event to trigger a signal of AO... My code is below. The code works fine and the OD goes off when you press the button E-Stim... But when pushed the button does not change with reliability the appearance (i.e. of the gray 'off' red 'on' color)... Sometimes color changes; no other time not... If I remove the structure of the event and the survey button in the appearance changes as expected.

    What is going on? I would like the button to change the colors on the user interface to indicate that it works... Should I programmatically control the color?

    Kind regards

    Jack

    I guess that when query you the button you have some delay in your loop? Locking means that the button will change its value when you press it, then switch back to the original value once the value of the control has been used by the code. When you ask, this means that until he reaches the next iteration of the loop, but in the case where the structure that will happen immediately.

    The default setting for the buttons to modify its behavior as in most of the application would be latch releasing. You then raise the event when the button of the mouse over the control. This also allows "drag" control if you push down on the subject, given that you do not release control in this case.

  • Mass changing the structures of events

    I have a VI in which I am coding a drag and drop events. The front panel has more than 200 indicators and Boolean values in which I want to make it able to accept a decrease from an event drag. My problem is the time it takes to change the structure of the event for all controls, one by one. Does anyone know how to change mass event structures quickly? Unfortunately I can't figure a way to do a drop with references to component event.

    There may be a way to do it using LabVIEW to script to automate the creation of a more complicated case of event.

    But you can try using the user events.  Use of control references tables introduced in a loop For to register for events on each control changing value.  Then you have a case of user event in the structure of the event which manages it.  If you dynamically build your event programmatically while running your VI, rather than do it manually by manipulating the event dialog boxes.

  • Get the button to change automatically after the structure of the case is completed once.

    Hi all

    The purpose of this VI (which I lightened it for the purpose of the present) is to do nothing until the START button is true. Then the structure of the case, and the string will be sent to the MSH. I need this too such that the stop command can be sent at any time and will be sent when the STOP button is true.

    At the present time, nothing happens until the BEGINNING is true, then the case structure begins and ends inside while loop. BUT then the outer while loop restarts again and the inside of a cheek through which returns once again the order of the string to the MSH (an unwanted process) because the START button is always true.

    Is there a way to get the start button to return to a State of false once inside while the loop is over?

    (Other solutions giving the same result would be very appreciated also!)

    BBRO says:

    The purpose of this VI (which I lightened it for the purpose of the present) is to do nothing until the START button is true.

    Well, your code sends a command to stop immediately after starting the program while consuming all CPU running the inner loop in parallel as fast as the computer allows. (Since there is no dependence on the data, the inner loop and the stop code both run at the same time. LabVIEW does NOT run left to right!).

    All you probably need is a simple while loop, a structure of the event with three cases and all the buttons in the action of locking.

    See attached a simple change, LabVIEW 9.0.

    (And please don't maximise front panel and diagram for full screen, especially if there isn't much here.) Sometimes we want to work on other things at the same time, for example to write this response!)

  • Change the condition in the structures of the event

    Hi all

    I am a student doing a project. I am very new to labview and I don't really know much of the function in labview. In any case, I have this timer made by using the structure of the event if I'm not mistaken (I downloaded this timer among the post on this forum). This timer will start at 0 sec, count up to 20 years, then stop. So what can I do to change the time of the end of this timer? Let's stop at 50?

    The program is attached. Please please explain or change the program and attached as a response. I tried to understand the help function, but still do not understand.

    I thank very you much in advance!

    Hello

    Thanks for your inquiry. The attached VI uses programming structures: while in the loop, the structure of the event and structure of the case. You'd have to change is in fact the case structure. Before going to, let us go through the different structures. Open the block diagram by going to the Menu bar of the front panel and go to the window-> open diagram.

    The while loop resembles a Do loop in text-based programming. It runs until a condition is met. Since the attached VI, it stops running when you click the exit button.

    The event structure is a structure that consists of sous-schemas. The structure meets the interactions with the objects of the front panel. For example, if you click Start or stop in the façade, the structure of the event will be a case that corresponds to this interaction. In the attached VI, the case, which corresponds to the interaction with the button start or stop, called 'Start', 'Stop': change the value. Each box contains an event handling routine.

    Structures of the case are like spending statements in the programming of text. Take a look at the 'Start', 'Stop': value change event. It contains a routine which consists of a box structure. The case structure meets the called Start input terminal (which is in fact the Start button on the front panel). The case structure switches between cases according to this entry. To display the different case just browse the structure of the case by clicking the left and right buttons. There are only two cases: true or false, as the entrance is a Boolean value.

    Now let's take a look at the VI. Take a look at the case "Timeout" of the structure of the event. This is where the change should be made. Change the structure of matter by editing the case. Change the numbers in the structures of the case: ... 20000 to ... 50000 and 20001 at 50001 This should do the trick.

    Kind regards

  • Changing Variables in the Structure of the case?

    Hi all

    I have a box structure. Depending on whether the case is t/f I would change the value of two variables. If I put two variables in the real part of the strcture case that they may not be in the wrong part. How would assign values outside the structure of matter? Could I refer to the time of their numeorus in different cases? Thank you.

    So, something like that?

  • Unforeseen event, captured by the structure of the digital change notification event

    Using the specific or similar to http://decibel.ni.com/content/docs/DOC-2280 code (change digital notification.vi) I'm observing behavior unexpected, but coherent structure of the event. The structure of the event capture an event, the first time data is received in the structure of the event; even if there was no change in the digital port assigned. After this initial unexpected event, the structure of the event behaves as expected.

    I just wanted to know if someone had a glimpse of it. What is the task of detection of change this event to initialize?

    In this case, you would have to ignore the event first, which in my opnion is valid because it reserve no value to a value.

  • Risks and impacts on the changes in the physical and logical structures used in ODI

    What are the risks and impacts on the changes in the physical and logical structures used in ODI?


    I wonder what can be changed and the risks and impacts that may occur changes in the physical and logical structures used in projects of ODI?

    You should not change the name of logic. Because in ODI, each model is connected to a logic diagram.
    You shouldn't be changing technology too because that would need a change to all models and the KMs that have been used in the development of interfaces and procedures, etc.

    Nothing under the physical schema can be changed for example. Connection, user, etc.
    ODI uses the logical schema. And it matches the physical schema in the runtime using contexts.
