Implementation of VI properties

Hello

I have a few general questions about the run properties VI settings.
http://zone.NI.com/reference/en-XX/help/371361B-01/lvdialog/execution/

I ready to build an application on the screws and considering the above settings. First of all, I wanted to know or at least have an idea of how much difference they could make in terms of speed or performance? This should I consider a trial and error type of situation, since I'm not 100% sure what settings would be best for me?

Here are the settings I'm considering:

What priority to assign to each VI?
What enforcement system to use?
Allow debugging?
Reentrante run etc?
Activate the automatic error handling?

Of course, I don't expect you someone to tell me these answers, but maybe just explain how much difference they can make.

Also, if someone could verify or correct me on this, but should I refrain from affecting a VI subroutine so that VI takes multiple inputs from the user and uses local and global variables?

Anyway, it's not that I don't already have the parameters in mind, it's just that I wanted to get a better idea of what can happen if I was not to select the best settings. I realize it's very general and Basic. Any response would be greatly appreciated.

Thank you

This will depend on your computer (IE memory, CPU, etc...), the operating system, coding efficiency, goal vi etc...

What priority to assign to each VI?

It really depends on what you're trying to accomplish. Normal priority is good for most of vi and applications I have ever developed. If there is time of the essential things that need to happen so you can create these more aggressive. This can cause problems on the road with something that hangs up while your 'more important' code is exicuting. Stay away from this unless you really need it. If your timing received criticism, you may need to look at a real-time system.

What enforcement system to use?

System performance to set topics for your code. If you give them the different enforcement system, you can see sutile coding of effects.

Allow debugging?

Does not have much effect.

Reentrante run etc?

This will depend on how many copies of this vi is tunning at the same time. If you use a vi in multipule places at the same time you can see a great improvement in efficiency that the software doesn't have to wait for the exicution of code at the end before it can be reused. This (if reentrant) code can be use symotaniously in all places at once.

Activate the automatic error handling?

Little or no effect on the schedule.

Also, if someone could verify or correct me on this, but should I refrain from affecting a VI subroutine so that VI takes multiple inputs from the user and uses local and global variables?

Here, you are very correct. You want to only set the subroutine code if the code is to treat and release. It will not store or update.

  • Description on the properties of account Dimension Essbase

    Hello world! I am a beginner on Oracle Hyperion and Essbase. I joined a company as a trainee software developer. My role is to support my superiors in the development of Planning and Budget Applications for Plantations of our society.

  • User with limited XP Home Edition privleges can not access an external hard drive

    I can't set up an external hard drive in Windows XP Home Edition so that a user who has 'Limited' privleges can access.  The user receives the access denied message.  I tried to configure this by starting in safe mode.  I shared the unit with everyone.  If I'm the administrator user then it can access the drive.  The troubling question is that this system has been configured with the user having limited privleges as well as access to the external drive in the past.  I recently removed Norton antivirus and replaced by MS Security Essentials and I'm so glad I did.  But now it's problem arose.  Any help would be greatly appreciated.

    You probably just need to change permissions for access of the disk and/or subfolders.  The following article describes how to do this:

    "How to set, view, change, or remove special permissions for files and folders in Windows XP"
      <>http://support.Microsoft.com/kb/308419 >

    The bad news is that this article was written for XP Pro and you have XP Home.  This means that the 'Security' tab, which is at the heart of the management of permissions is not present during the implementation of the properties of file or a folder on your computer. (Or y at - it an option to disable Simple file sharing).  The good news is that if you start your computer in safe mode (repeatedly tap the F8 key when your computer starts) and log on as a user with administrator privileges, you can then obtain access to the security"" tab.  Once you have access to this tab, you can give "Everyone" permission to all of the disk if you wish.  Once you set the permissions as you like them, you can restart your machine in Normal mode.

  • Obligation of Notification of App World Air time use

    To correctly formulate demand with App World Blackberry, if the application will eventually generate fresh air to the user when he or she uses, you must put a notification display in the application so that they don't be blinded.

    The management of THAT RIM publishes, you can code something hard like a labelfield on the opening screen or (much better), you can provide a way for the user to prevent the notification continue to appear once they probably read it once.

    Has anyone code an app that has displayed a warning - perhaps via a dialog box - when the application is started, but can be put in sleep for good by the user?

    If so, could you give an example of how it works?

    Thank you

    You want to create an implementation of PopupScreen that includes the caveat, an "OK" button and a "do not display this message" check box.

    If the user selects the checkbox "do not display this message", you'll want to set this parameter in the persisted data store.

    The implementation of the PopupScreen is quite simple. You will need to extend this class, add a check box, a button and a text box, a manager of vertical field.

    For general purposes, I sugget that you develop your own implementation of 'app properties' of PersistentDataStore. You'll want to be able to save or retrieve name/value pairs, like "dontAsk'true '. We persist a hash table for that object.

    There is a tutorial on persistence here:

  • After restarting computer music library settings tris change again by default.

    Original title: WMP 12 library issues

    In my library, I try to have the media player sort by artist, and then within each artist folder, by release date.  However, it is easy to sort by artist, I can't sort by release date and stay that way.  Whenever I turned off the player or open another artist, the sort changes are canceled.  I can't find any option to implement the same properties for all the records, and constantly having to change the sorting properties to find the music is driving me crazy.  I hope that I'll have just a moment dumbass and there is a quick fix.

  • Preloading cache: is it possible to preload data in a transient properies associated with a descriptor of point?

    Hi all

    I expanded my custom-catalog SKU point-descriptor to implement some transitional properties as described below:

    • stockLevel transient property. -.

    Used to store the stock hand available for certain SKU, this will hold the cached value of the stock that was once recover since the StroreInventoryManager until one of the following scenarios appear on board:

        • The stockThreshold property is great hold value in the stockLevel property.
        • An interval of time previously set by the configuration for the use of the cached value has expired and we need to get the current information for the repository.
    • stockThreshold transient property. -.

    Used to store a configurable threshold stock.

    • lastStockCheck transient property. -.

    Used to know the last time that the stockLevel property has been updated with current information from the repository.

    • stockIntervalCheck transient property. -.

    Used to calculate that the time elapsed since the last update of the stockLevel property.

    StockThreshold and stockIntervalCheck properties are pre-defined in a properties file, which can be configurable.

    StockLevel and lastStockCheck properties are defined dynamically on Runtime application.

    Is it possible that I can load before the two type of properties?

    In your custom property descriptor class you set this property in the cache?

    The first time when the getValue is called on this property his goes to fecth the repository and set this property in the cache.

    so one thing you can do is to write a component that would kick off just after starting the application and it can browse the references sku and sku.getStockOnHand () of the call, the call to the Get accessor would actually stockOnHand property in the cache

    the method in the custom property descriptor must get and set the value in the cache as below.

    @Override

    public Object getPropertyValue (RepositoryItemImpl pItem, Object pValue) {}

    the pValue is the property value that is present in the cache

    If (pValue! = null & pValue! = RepositoryItemImpl.NULL_OBJECT) {}

    return pValue;

    } else {}

    String stockOnHand = getStockOnHand (pItem); get the value of the repository

    {if (isCacheable ())}

    pItem.setPropertyValueInCache (this, stockOnHand);

    }

    return stockOnHand;

    }

  • Method Property set on the application class get

    Hi mates,

    Please help about this.

    I am self-taught on the peoplesoft application class.

    And I found that it is different from JAVA for property get method.

    Test cases, see the screenshot:

    http://note.Youdao.com/share/?ID=becfc6c74793a12e468d3f2b195a1816 & type = note

    When I create the class instance in record application peoplecode, messagebox, then the x property.

    then shows MessageBox (0, "", 0, 0, "herehere111") and the x is 1, stands for her running the get method, not run the set method and the value of z is not set at 222.

    How to call the set method?

    Reference on peoplebook:

    Set

    Syntax

    SetPropertyName StatementList End-Set

    Description

    Use the construction of the language during the implementation of the properties in an application class. All of the properties in an application class must be named uniquely. The new value for the property is available in the & parameter NewValue to the Set method.

    Note. You cannot create a property only. You can create only the get - set properties.

    Parameters

    The value PropertyName

    Specify the name of the property that you are implementing.

    StatementList

    Change the value of the property to be & NewValue.

    Returns

    None.

    Example of

    Set FruitCount &Fruitcount = &MyFruit[&NewValue].ActiveRowCount();

    End-Set;

    How the method to be called and the value & NewValue to pass?

    Appreciate it for any guide.

    Thank you.

    Set method is called when you assign a value to the property of the object.

    for example:

    & myFruitObj.FruitCount = 10;

Thus the old saying: "Seeing IS believing.", is NOT true.   This is a more current peeking process, an advancement on the old "300 watt bulb behind the envelope" method of finding out contents withOUT opening the letter.

    Thank you, you, Matt.
    Regarding the "peek-a-boo," about 15 years ago, it was somewhat revealed the Web that some shippers had the ability to detect IF you had opened their missive.

    This is handled by the Web beacons. Thunderbird blocks remote images by default. Web beacons work only if you enable the remote images in specific email.

    From THIS time, it is the GOVERNMENT that has the ability to detect if you open all or part of your receipts "Entrants".

    Interesting point of view, but not quite corr4ect. f they have access to a mail server IMAP "could" determine the status of mail on this server. In the case of POP e-mail that could determine if it has been downloaded. While I do not trust of Government oversight. About the only time where they would do that would be when they are already studying you as an individual. It's a slow late then.

    So, WHY Windows Mail offers this function and the T-bird, NO mail?

    I played with Visual basic using integrated Internet Explorer about 15 years ago and it was a simple toggle to change the display of the HTML displayed in the source. So I would say it is in windows mail, because he was already in Internet explore and it made for a very simple to implement the functionality. Just expose the existing functionality. After all the composition and rendering in Windows mail used Internet explorer.

    Although the header can help tremendously, , what I SEE is NOT NECESSARILY WHAT THAT REALLY is the content of the e-letter.

    This is a feature of Thunderbird. It uses the display names from your address book on incoming mail. You can disable it in the menu (alt + T) tools > options > advanced > reading and posting.

    If the follow-up can be done via the 'Key STROKE' method, and YOU do NOT know of it, then a "peek-a-boo" is useful to have, huh?

    Keyloggers are all also able to capture screens and clicks. If your number more ahead.

    It makes me feel, I have a FEW C-O-N-T-R-O-L that I CHOSE to read, and what I based on the content and subject.

    Seriously. encryption of e-mails with s/mime and free email certificates will do more to protect your mail that any kind of fake check before you read. Most of the people may face apparently not having a certificate of personal mail to encrypt their mail and like most internet technologies, we get the lowest common denominator. This is the plain text that scours the internet to an ordinary human-readable text.

    Please when using these forums not your text indent. This is what makes it become very difficult to read and not wrap. I don't know that that is how you were taught in school. I learned the same thing. But it must comply with the requirements of the opportunity.

  • To access properties such as 'Runstate.LoopIndex' in subsequences.

    Ok.  I know that you can enter individual properties and pass them as parameters (which is what I do), but I was wondering how I could do with more elegance...

    I have a top level sequence that calls a routine Test, and I put the property of closure of this routine.  This in turn calls a 'Report' sequence that passes the back loop to the Interface State.

    I'm trying to pass the RunState object until my subsequence.  But there is no function "AsRunState", so I can't seem to access its properties.

    Looks like I'm passing on the properties of 4-5 individually.

    In any case, is there a way to do this?

    Well, in this case there are a few options.

    You can use RunState.Caller.Runstate.Caller.Runstate.LoopIndex where you reference 'Runstate.Caller' for as many levels return to the top of the list, you need to go. It's a little kludgey if you don't know how many levels you have to cross.

    If you know you're from the MainSequence, then Runstate.Main.LoopIndex will give you what you want - you should be able to see almost everything in the duration of the MainSequence from there.

    From ThisContext parameter has worked too - as I experimented with both methods and got the same results for LoopIndex value.

    Above is possible, it remains to be seen whether or not it is a good idea to implement... use at your own risk!

    Is that what you are looking for?

  • Changing the properties of the individual elements in the array

    In the attached VI, I have a table 1 d of the slider ('Phase Coefficients') controls where each element of the array represents the coefficient in a polynomial of arbitrary order. The problem I have is that the range of slider, I put to the coefficient of the lowest order (element 0 of the array) becomes quickly impossible for one more order coefficients (> 5 elements). Small changes in the highest order coefficients dramtically change the global polynomial.  I want each element/slider to have its own line, but I know that's not strictly possible that each element of a table shares the same properties. I've implemented a work around (use boolean to activate) in which the range of all cursors is set according to which the item is viewed, but my implementation prevents the modification of the range during execution of the VI. Is it possible to adapt my method (or use another method all together) in order to allow different, editable for each slider element ranges?

    Thank you!

    Each element of an array must have the same properties.  They can only differ in value.

    You can have an array of clusters, and each group can have the slider control.  Here, you will be able to regroup a slider with different properties in the cluster build clusters in a table.
