LVOOP: Common accessor for the child classes?

Similar Questions

• Private data LVOOP Parent returned when the child instance created from constant

  I created a parent class and child class.  For each of these classes, I created a member who is a builder, whose purpose is to initialize constants for each class and return the instance of the class VI.  I also have an accessor Member VI for each class that returns private data of the class (in this case, a single string for each class).

  Private class data Parent 'String' is set to "text Parent" as default.

  Private data of the class of the child 'Child String' are set to 'Child text' as a default.

  The Parent class constructor works very well.  For testing purposes, I'll be back the text of unbundling of directly the manufacturer VI, as a return of the VI accessor. The Parent constructor starts from a class constant.

  However, in the case the constructor of class as a child, if I start from a class constant, unbundling directly private data (using a feature of unbundling by name and choosing "Child String" as the element), I get the private parent data!

  If I use the Member of the class of the child VI to retrieve the text, I get the private data of the child.

  If I change the constructor from a class of control instead of a constant class, I get the private data of the child.

  This occurs only until the child class has existed as a control flag. that is, if I ungroup private data, after the class is returned by any Member VI, I get the private good child data.  Then, of course, something changes once the class 'data' has been a control at a given time.

  I'm using Labview 8.6.1, Windows XP

  I have attached a small project that demonstrates the problem that I encounter, without actually doing initialization, just read.

  Is this expected behavior?  Why does it matter if I start with a constant of class instead of a control of the class?  When you slide the block diagram in the project window, you will always have a constant.

  Although I was able to reproduce your problem in LabVIEW 8.6.1, it seems to work fine in 2009.  I could not find a CAR ID, but at this point I can only assume that the behavior was not intended but it is set in 2009.

  Let me know if you need me to find more details.

• Prevent the child class dependency when the conditional use disable to specify the class in the development environment

  Hello

  I develop an application that I want to run on the normal systems and in real time using LabVIEW Proffesional Development System 2012 SP1

  To control how the application interacts with the user, I created a class that defines the type of user interface behavior that should allow me to have nice dialog boxes when the system is running on a machine windows and no dialog box (or any other friendly code in non-real time) if they sail on a real-time target.

  The parent class is the code that suits the actual time and the class of the child is the one with dialog boxes.

  To control the class of which it is responsible, I have a structure conditional disable. It works fine when the application is built in an executable or executable file in real time, but the problem arises when I want to use the code during development on the target in real time.

  I think that with the application under a target in real time (RT PXI), the proper case of the conditional - disable is enabled for the parent class is used, but the child classes are also listed under dependencies - I pressume it's because they exist on the block diagram in the case of persons disabled conditional turn off the diagram.

  This means that I can't deploy the code on the target in real time as it is unhappy with the class of the child code - even if it will never run.

  To save the poster my real project, I created an example with a Parent and child class and a flag to disable conditional 'class' to illustrate the problem.

  If you run Test.vi, you will see that the child class always gets locked (i.e. is addictive) while running even if it is not called.

  So - basically my question is: is what I can do about it or will I enough to disable it with conditionals and simply put the constant to correct class on the block diagram in the tests?

  Thanks in advance

  John.

  I feel your pain.  I came across something similar some time back.

  Apparently official NOR position is that you have to put a conditional structure of Disable IN EVERY ONE OF YOUR CLASS live.  In the Windows screws, you simply have a case of empty disable conditional with the windows code in another case and vice versa on the RT.

  I also much prefer the method you describe...

• Error 1448. LVOOP: Referring to objects of the child class

  Hi all.

  In a project using LVOOP, I defined a class parent with several attributes. Of this class, there are three classes of children who inherit the attributes of the parent class and also have their own.

  Imagine that I instantiated an object belonging to the parent class and initialize its attributes. So I want this object even belong to a class of the child in particular, and refer to its attributes in the class of the child, of course, keep the values of the parent class. How can I do?

  I tried to use "in a more specific class" tool but I get the following text: "error 1448: bad type cast." LabVIEW does not deal with the run-time value of this class of LabVIEW as an instance of the given class of LabVIEW. »

  Exactly the same problem is committed and solved here http://lavag.org/topic/7473-lvoop-class-variable-as-child/, but because the links are temporarily disabled I can't download and understand the code example, which shows what it says there.

• Substitution of the class, how to create the child class and then the base class

  I started to write a program for a DMM smart, that the problem is all versions of DMM greet the change company communication.

  My idea is to write a child class for each version, DMM and each Subvi child will replace the Subvi base class.

  My problem is, I first want to create a child class and after I see everything is working, start creating the base class. in this way, I'll see if think the right way.

  My question is

  How can I create a child class and then create the base class and configure the Subvi class of the child to be the substitution of the base class?

  I tried searching in the property of the class, but I don't see anything.

  Thank you

  This can be done and I did on occasion.

  You create the base class with the methods of dynamic distribution, you need (Connector components must be identical to those of the class of the child).

  Set then the legacy of the class inherits this base class.  If your method is defined as a dynamic distribution method in the parent, you will probably now have some errors (unless your method of child was already DD, in which case you might be OK already).

  To change the inheritance of a class, right-click on the properties of the class in your project, and then select Properties.  According to me, the tree of estate is at the lower end of the property.  Click on the 'legacy of change' (or something similar) to choose the class from which you now want to inherit.

• Canvas, click events for the child objects

  I am trying to record an event for each child object.
  and I use the following code
  
  http://livedocs.Adobe.com/Flex/3/HTML/Help.HTML?content=events_08.html
  in the part of the examples (second example)
  
  However, I am dynamically add custom Image objects extended and when click on a displayed Image and check for its type if its correct type, it would just return false.
  Alert.Show ((event.target_est_dans_MyAClass).toString ());
  
  When clicking on one of the children is opposed and display the event.target.name and it's just also displays a silly 'FlexLoader74' or whatever number. Somehow, it loses its properties or the type of the object.
  
  Is there something that I am missing?

  The loaded image, you click on IS what would return with event.target. It is added to your image class extended as a child of this class. So it's probably that you want to do:

  Alert.Show ((event.target.parent_est_dans_MyAClass).toString ());

  Keep in mind that if EMBED you your images in your image personalized instead compile-time class, then you can check for this as you did before:

  Alert.Show ((event.target_est_dans_MyAClass).toString ());

  Unfortunately we have not all people who are very experienced with Siebel on this forum. It seems to me that it should be possible using the Transformation engine. The other option is to transform the XML into a PropertySet, retrieves the values that you want to update, and then update in the appropriate component of the company.

• default skin for the button class spark

  Hi, where in the button spark or superclasses class specifies its default appearance?

  The Spark as Button.as components do not define their default skin internally. If you want to have a skin by default so that you don't have to manually specify the skin whenever you have two options: skinnable component. One that is used in the flex sdk, and the preferred method is to use a css file to specify the skin for the component. If you do not want to, then the other option is to call setStyle ("skinClass", YourSkinClass) within the constructor of the actionscript component.

  UD_ERPROLE is not NULL

  Action is Add

  Equal to ERPAccountPayable role name

  
  

  Here, what can be the expression for case 3 switch above?

  first a I do: bpws:getVariableData('requestDetails_OutputVariable','RequestData','/ns16:RequestData/ns16:BeneficiaryData/ns16:Beneficiary/ns16:Entity/ns16:DataAttribute/@Name')

  but it helped... any help appreciated.
  

  Hello

  Not sure what you mean here...

  UD_ERPROLE is not NULL

  It seems that UD_ERPROLE is a value for the Name attribute, so if you try to get the first DataAttribute where Name = "UD_ERPROLE", the expression would be...

  /NS16:RequestData/NS16:BeneficiaryData/NS16:beneficiary/NS16:entity/NS16:DataAttribute[@name = "UD_ERPROLE"] [1]

• How to limit the voltage common mode for the switch

  The user manual mentions a maximum of ±12V ground for my switch (pxi-2536) but I do not see an entry in the field on the pinout of the connector. If I have a floating supply, should I connect the ground to the chassis on the ground on the back of the PXI? Is there a better way to limit the common mode voltage?

  Thank you specify, it makes much more sense!  The best way to go about this that seems will be grounded to the negative terminal of your power supply to ground the chassis security, as I think you suggested at the beginning.  I don't know what frame you have, but you should be able to find a "Reason for connection security" section in the manual. For example, here are the 1044 chassis manual, with the present article is on page 2-4. http://www.NI.com/PDF/manuals/371360a.PDF

  This should take care of it and avoid Earth loops!

• How can I change the registry values with a common search for the string and replace the function where I don't do all manually?

  Due to problems of space with my installation of XP Pro, (operating system has been installed on a 4 GB partition and I did have a copy of the OS to do a new installation) I am trying to move a number of files on a mounted drive.

  It is a way to search an entire record of [SPECIFY FOLDER] "C:\Program Files\" instances and replace each with "C:\Program Files\Overflow\ [SPECIFY FOLDER]" as a common discovery replace function?

  Also, I'll have to move several "Common Files" files in the mounted folder 'Overflow '. The method to make learning one should help me to do both. Manually, it will take most of thousand years that all the files in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components
  the files seem to have a key value have changed.

  I have already uninstalled and reinstalled some programs at the desired location, but many still use the "Common files" folder despite my having already changed the default installation directory path in the registry. Any help would be appreciated.

  Thank you

  NORTH CAROLINA

  One way:

  1. Start Regedit (start-> Run-> 'Regedit')
  2. Select the branch of the registry, or you are interested in changing.
  3. The export of this branch of the registry (file-> export) in a ".reg" file
  4. Use a programming editor (for example, the freeware Notepad ++) and use the "Find and replace" function to make the changes you want.  Save the modified file.
  5. After making the changes, double-click the .reg file to fold changes in your registry.

  As always, keep a backup of your original registry in case things get really bad and know how to do to restore this backup your machine should not be able to start.
