To access the added Variables of Classes dynamically

I'm not sure what the terminology is here, but it's what I do.

I added the officials in the field via a loop and add to the screen

     // loop through all of the elements and setup the forums
        for (int i = 0; i < size; i++)
        {
            c_ForumSelect frm = new c_ForumSelect();
            frm = (c_ForumSelect) v_forums.elementAt(i);
            hfm_forumselect new_forum = new hfm_forumselect(frm);
            mainManager.add(new_forum);
        }

I wrote the code that allows to "highlight" the domain manager.

Is there a way to 'read' the Manager added variables?

For example, if I had a Variable called 'ID' within the hfm_forumselect... How I acceding that when sound highlighted on the main screen of the user interface...?

Who is?

You can add them to a datastructure, a vector, for example. When you add them. Or add the database instead. or you can use the container Manager, navigation using getFieldCount and getField (index).

Access a public variable between classes

Hello

I have two classes running... one is a class of documents (EgoGame.as) and another is a class linked to several similar clips (Ball.as).

I'm trying to access a public Ball.as variable that has been declared in the class statement EgoGame.as.

When I run the test output includes the following...

1120: access of undefined property _ballPlaced.

Here is my code. What I'm trying to do is remove the Ball.as event listeners when the _ballPlaced variable is true, so that the user cannot drag and drop the balls after that that they were placed in a box... pointers greatly appreciated!

each place you have a ball of reference you have access to the lockBall() method. so, if ball0_mc is a member of Ball class, you can use:

ball0_mc.lockBall ();

Call the function in LabView from a DLL, and then access the global variable of DLL

I've created a DLL in LabWindows with a function and structure. I want to call the function from LabView and then access the overall structure. I am able to call the function in the DLL with a "call library function node" and has access to the return value, but I can't understand how to access the overall structure. The structure is declared in the header DLL with __declspec (dllimport) struct parameters file.

Is it possible to access this structure without using the library of network variables?

My guess is that you need two bytes of padding after "in_out" and another to two bytes of padding after "anin." The reason being that ints are 4 bytes, and most of them C compilers will align on 4-byte boundaries. The struct will naturally start to such a limit (in fact, in Windows, it will probably start to an 8 byte boundary). If you then count bytes in your structure, you are 70 byte after "in_out." 70 is not divisible by 4, so you need 2 bytes more to reach the next 4 byte boundary. You can also you could reorganize your struct so that "anin" follows "in_out" and this is probably the best option if it won't cause you other problems.

Unlike most C compilers, LabVIEW compressed structures as closely as possible, without filling. I don't know enough about the history of LabVIEW and internal parts to explain the reasons and to do this performance penalty, but, as choice of LabVIEW "endianness", it is probably a remnant of the first versions of LabVIEW that were running on the Mac.

If for some reason you want to force your C struct to match package LabVIEW, you can use the #pragma pack (x) directive, but I wouldn't recommend that here because you can control the C and LabVIEW.

EDIT: in the cases where it was not clear, add padding to your cluster of LabVIEW, insert appropriate size or items at the place desired in the cluster.

Trouble accessing the Quiz Variables with HTML5

Hello.
I am trying to create a custom results page.
I use the following code to return the total number of points scored,
myScore = cp.variablesManager.getVariableValue ('cpQuizInfoPointsscored');
This seems to return zero no matter how complete the quiz.
How can I access the actual quantity of points marked on my personal page?
Thank you
Dongo

You should be able to access the variable as you are, but as you have noticed, there are inconsistencies in the output of HTML5. Here's another way to get to the quiz variable:
```
cp.model.data.quizzingData.quizInfoPointsScored;
```
You will notice a lot of quiz data can be extracted from the cp.mode.data.quizzingData object.

Best,

Access the static variable...

Hello

I need a static variable which holds a QMap, for this example I'll use QMap.

I created fresh new project and I changed in applicationui.cpp:

...ApplicationUI::ApplicationUI(bb::cascades::Application *app) :
        QObject(app)
{
....

    initDatabase( 1 );
    initDatabase( 2 );
    initDatabase( 3 );
    initDatabase( 4 );
}

bool ApplicationUI::initDatabase( int index )
{
    QString database = QString( "Db%1" ).arg( index );
    QString value = QString( "data/db%1.sqlite" ).arg( index );

    ApplicationUI::m_databases[database] = value; // undefined reference to `ApplicationUI::m_databases'

    return true;
}

ApplicationUI::~ApplicationUI()
{
    if( ApplicationUI::m_databases.count() ) // undefined reference to `ApplicationUI::m_databases'
    {
        foreach( const QString &key, ApplicationUI::m_databases.keys() ) // undefined reference to `ApplicationUI::m_databases'
        {
            QString db = ApplicationUI::m_databases[key]; // undefined reference to `ApplicationUI::m_databases'

            qDebug() << "Closing [" << db << "]";
        }
    }
}

and in applicationui.hpp:

...

class ApplicationUI : public QObject
{
    Q_OBJECT
public:
    ApplicationUI(bb::cascades::Application *app);
    ~ApplicationUI();

    static QMap m_databases;
    bool initDatabase( int index );
...
};

#endif /* ApplicationUI_HPP_ */

As you can see commented in the code above, I get error:
no reference to 'ApplicationUI::m_databases' applicationui.cpp

I thought to access static variables that ApplicationUI::m_databases would work.

Can you please guide me here.

Kind regards

Andy

Hello! That's what I saw:

(1) #include is present in the header file?

' (2) ' void ' is the syntax error:

void MyClass::~MyClass()

static QMap variable;

is a declaration, you also need to create the variable in the .cpp file. Add to the .cpp:

QMap MyClass::variable;

MyClass::variable["one"] = "value One"; // doesn't work...

"MyClass:" is not necessary. ['a'] variable should work too.

UPD: this compiles (I replaced QMap QString with std::map with std::string for quick test):

#include 
#include 

class MyClass
{
public:
      MyClass();
      ~MyClass();

      void someMethod();

      static std::map variable;
};

std::map MyClass::variable;

MyClass::~MyClass()
{
     // do some cleanup... using MyClass::variable, doesn't work
}

void MyClass::someMethod()
{
     variable["one"] = "value One"; // doesn't work...
}

int main(void)
{
        return 0;
}

To access the page defined by a dynamic action item
I have a page element that is defined by a dynamic action. However, if I try to access this page anywhere else on the page element, it is null. Y at - it a specific method to dynamically reference the value of page elements, other than the usual & p2_page_item. reference. TIA.
Hello!

Where do you reference point? In another DA, process page?

& NOM_ELEMENT. the syntax is only for the static text and it will be avoided in SQL and PL/SQL. It will get only value when the page is loaded.

If you are referencing the element DA or JS, you can get its value with the function $v (for example $v('ITEM_NAME'). If you reference the process item, you can get its value with the standard bind variables syntax (: nom_element) or with the function v (for example v('ITEM_NAME'). If this process is inside the dynamic action, value of the item must be saved before session state.

(Question LVOOP) How one access the data of another class in another class?

Hello-

Ass title suggests, how do I access another class (or is it class?) data from another (different) class? I will attach a picture showing where my problem is...

I was told this:

http://zone.NI.com/reference/en-XX/help/371361H-01/lvhowto/setting_scope_classes/

May contain some helful info, but I can still understand how to unbundle Renault of classes inside the component class data (as seen in the attached photo).

I think there could be something simple I'm missing here when it comes LVOOP or OBJECT-oriented programming in general... If any of you are willing to help me, it would be much appreciated!

Thank you!

Personal data are always private, you can never set public. Unbundle cluster function can be used only on the thread of class when he is in the class. If you need to access private data, you must create accessors.

It of simple, just the class right click and select new, VI for access data members. He invites you to a dialog box to fill you with what you want to create, elements of data and if you want them available through property nodes (recommended). Once completed, this will generate the Afterward screw., you can use in any other VI. The nice thing about making them nodes of property is that you can plop down a property node and it thread class, and all the created accessor functions will appear in the list.

Pass the URLLoader() variable between classes

I have two classes. See below.
What I want to do is quite simple, but I do not know how to do. I want the URLFactory for create table and store it in the variable 'dataArray' and use the table in the main class, by calling the GetList() class URLFactory. I have returns nothing... Please help
Basically, I need to set a variable equal to URLLoader.data (var something: String = URLLoader.data) so I can use this variable in other classes. WHY ISN'T IT EASIER? Please, I beg you. A solution would be much appreciated.
package classFiles
{
import flash.display.MovieClip;
Import classFiles.URLFactory;

SerializableAttribute public class MainClass extends MovieClip {}
private var _UrlDriver:URLFactory;

public void MainClass() {}
_UrlDriver = new URLFactory ('url');
var temp: Array = _UrlDriver.GetList ();

}

}

}
package classFiles
{
import flash.net.URLRequest;
import flash.net.URLLoader;
import flash.display.MovieClip;
import flash.events.Event;
import flash.sampler.Sample;

SerializableAttribute public class extends MovieClip {} URLFactory

private var loader: URLLoader;
public var textData:String;
public var dataArray:Array;

public void URLFactory(url:String) {}
textData = "";
this.dataArray = new Array();
loader = new URLLoader();
loader.addEventListener (Event.COMPLETE, HandleComplete);
Loader.Load (new URLRequest (url));

Temp = CreateDataArray();
}

function HandleComplete(e:Event):void {}

textData = loader.data;

trace (dataArray);

}

function CreateDataArray (): void {}

trace (dataArray);
dataArray = textData.split ("\n");
dataArray = textData.split('","');
}

public void GetList (): Array {}

return dataArray.

}
}

}

Yes, the data loading is not instantaneous. This is why you use a complete listener in your factory.

Similarly, you must use a listener in your main class to check if the data is ready.

p.s. Please check the useful/correct.

Access the function of custom class which is stored in a table?

What about this object that is in the constructor function of this object is as I do to send a parameter of sprite that will act as it's parent..,.
var anObject:myObject = new myObject (parentSprite);
and in my main project, I used those object and store in a table after it is added to the scene...
I store it in a table cause I have to be able to return to the it...
everything was fine until I have to call the function inside this object which I already stored in a table..,.
so, how should I call the function in this table object that has stored the object?
hope that I specify me...
Thanks in advance guys..,.

You can either pass data as an argument to the constructor, or a
property (preferred), or you can watch using a Singleton class.

To access the Global Variables in the functions/methods

Which of the following statements is better in terms of performance and efficiency?
public var a: int = 0;

public void add (): void {}
a += 5;
}
Addition();
OR
public var a: int = 0;
public void Addition(b:int):int {}
b += 5;
Back to b;
}
a = (a) Addition;

I saw a lot of guides discourages the use of global variables in the functions/methods, but I just don't understand why anyone would create a copy of the variable, modify this copy and to grant this value to another variable and throw.

You must create an instance to pass to your function. the parameter (for example, mov) does not create a separate instance and creates only a temporary pointer to the passed object.

If an instance is prepared for gc, having spent this instance to any number of methods (as a parameter) delay / will not interfere with ca.

and Yes.

MOV ['x'] = mov.x,

MOV ["rotation"] = MOV.rotation,

MOV [anypropertystring] = MC.anyproperty

Flash uses array notation to solve strings into objects:

var var1:ClassType = new ClassType();

This ['var1'] = this.var1

Not able to access the parent instance variable in outside of the methods in child
Hello

I don't get why I am not able to access the instance variable parent class apart from the example of the child class methods.
```
class Parent
{
     int a;
}

class Child extends Parent
{
     a = 1; // Here i am getting a compilation error that Syntax error on token "a", VariableDeclaratorId expected after this token
     
     void someMethod()
     {
          a = 1;  // Here i am not getting any compilation error while accessing parent class variable
     }
}
```
Can someone let me know the exact reason for this, and what about the talks of error?

Thank you
Uday

Published by: Udaya Shankara Gandhi on June 13, 2012 03:30
You can only put assignments or expressions inside the methods, of the builders or the initializors class, or when you declare a variable.
It has nothing to the child which stretches from Parent.
```
class Parent {
    int a = 1;

    { a = 1; }

    public Parent() {
        a = 1;
    }

   public void method() {
       a = 1;
   }
}
```

to access the data of the children with the static accessor of parent class

I'm new to LVOOP. I'm trying to create accessors of data in the parent (static) class and use them in the child's class. I don't need them to be dynamic becase the accessors are identical for child and parent. Is it possible to access the data of a class without creating an accessor for each class?

It is the dynamic method that I created that finally works. Once I found the VI "call Parent Method.vi' everything has worked.

So now I created all my data as static accessors and my methods are dynamic (assuming that they do).

Thanks for all the help.

To access the XML from a different class

Hi all
I have a xml class that loads the xml data, I need to access the data of another class. I imported the xml classinto the new class and created a new instance of it. However when I try to access the xml data it come back as null. I understand that it is certainly because when she is called the xml data has not completed loading. How can I get around this?
XML class:
package {}

flash.xml import. *;
import flash.events. *;
import flash.net. *.
import flash.display. *.

public class xml extends MovieClip
{
public var xmlRequest:URLRequest;
public var xmlLoader:URLLoader;
public var xmlImages:XML;

public void xml()
{
xmlRequest = new URLRequest ("images.xml");
xmlLoader = new URLLoader (xmlRequest)

xmlLoader.addEventListener (Event.COMPLETE, xmlLoaded);
xmlLoader.load (xmlRequest);
}

private void xmlLoaded(event:Event):void
{
trace (xmlLoader.Data);
xmlImages = new XML (xmlLoader.data);
}
}
}
Thanks in advance

Or even better:
```
package {     import flash.events.*;     import flash.net.*;     import flash.xml.*;

     public class XMLLoader extends URLLoader     {          public var xmlImages:XML;

          public function XMLLoader()          {

          }

          public function loadXML(url:String):void {               this.addEventListener(Event.COMPLETE, xmlLoaded);               this.load(new URLRequest(url));          }

          private function xmlLoaded(event:Event):void          {               trace(xmlLoader.data);               xmlImages = newXML(this.data);               dispatchEvent(new Event("loadComplete"));          }     }}
```
Use:

var xmlLoader:XMLLoader = new XMLLoader();
xmlLoader.addEventListener ("loadComplete", onXMLLoad);

xmlLoader.loadXML ("images.xml");

function onXMLLoad(e:Event):void {}
trace (xmlLoader.xmlImages);
}
