• Pass a variable to the main class to a MovieClip

  Hello!

  I have a document with the main class.

  I have also a few clips that have their own class and functions.

  I'm trying to pass a variable in my main class to one of these clips.

  I tried a few things, nothing has worked.

  Who can help?

  Match_Easy looks like a class name.  You must use the name of the instance.

• fieldChange get variables from the main class

  I'm doing a simple calculator that users enter numbers, press on calculate, and the answer is displayed in the status bar.  The problem I have is that when I try to get the EditFields values in the fieldListener, I get an error that says that the variable was not found.  Here is an example of the code that I have:

• recovery of the external class variables

  I created a class loader that retrieves variables from an external text file. I call the loader class and everything works fine but I can't figure out how to get and use variables in the main class. Can someone help me please?

  Call main class:

  function createInfoText (): void {}

  var loadTxt:LoadTxt = new LoadTxt("text_files/mainTxt.txt");

  }

  Class LoadTxt:

  package app.gui

  {

  flash.net import. *;

  import flash.events. *;

  public class LoadTxt

  {

  private var externalTxt:String;

  public var loader: URLLoader = new URLLoader();

  public void LoadTxt (external)

  {

  externalTxt = external;

  init();

  }

  function init (): void {}

  loadExternalText();

  }

  function loadExternalText (): void {}

  loader.addEventListener (Event.COMPLETE, handlerComplete);

  loader.dataFormat = URLLoaderDataFormat.VARIABLES;

  Case of load data

  Loader.Load (new URLRequest (externalTxt));

  function handlerComplete(evt:Event):void {}

  var loader: URLLoader = URLLoader (evt.target);

  trace (Loader.Data) //this works OK

  }

  }

  }

  }

  I know I have to get the data that is held in the var 'loadTxt' but I'm brain-dead!

  Thank you

  Here are a few things to think about...  The LoadTxt class must have loaded the file until the master file can try to access it.  If the LoadTxt class should be a way to tell the main file, it is ready.  What you could do in your handlerComplete function is hurry up an event for this purpose and have an event listener assigned to the instance of LoadTxt, so that the data can be extracted from it when it's ready.

  You can use the custom LoadTxt class event class to pass data in the event that hurry you, if you won't read about the creation/use supported the transmission of parameters.

• Get the value of the bind variable in backing bean class VO Impl

  Hello
  
  I have a VO that includes a bind "pOrgId" variable, the VO has a java VO Impl class that includes:
  
  /**
  * Returns the value of the variable to pOrgId.
  value of the variable * @return for pOrgId
  */
  public {getpOrgId() number
  return (Number) ensureVariableManager () .getVariableValue ("pOrgId");
  }
  
  So it is possible to obtain the value is concluded by the binding variable using this class in a backing bean? (I tried to import the VOImpl class in the bean to support, but getpOrgId is not available?).
  
  (JDEV 11.1.2.3.0)
  
  Concerning
  Carl

  Hello

  When you create a ViewObjectImpl class, none of these options is to generate the getter/setter for bind variable. Create a client class interface and expose the get method for the variable binding. Now, you can reference the method since a binding method in the ADF, which you then access a managed bean by calling

    BindingContext bctx = BindingContext.getCurrent();
    BindingContainer bindings = bctx.getCurrentBindingsEntry();
    OperationBinding oper = (OperationBinding) bindings.get("name of the method binding");
    Object returnVal = oper.execute();

• To access the upper class instance variables

  Hello
  
  See the code provided below. If home * variable 'i' is not set to 4, the output will be 3, if it is set, it will be 4.
  My question is... Well, I don't know exactly, there would be a lot. All this is strange to me.
  (For example, it seems that for the super class constructor runs when I access an instance of her variable).
  Could someone explain this topic or maybe help me to direct to an article?
  

  public class TryThis {
      
      public static void main (String args[]){
  
           Child c = new Child();
           c.seeSuper();   
      }
  }
  
  public class Parent {
  
       int i;
       
       Parent(){
            i = 3;
       }
  }
  
  public class Child extends Parent{
  
       Child(){
            //i = 4;  //***
       }
       
       public void seeSuper(){
            System.out.println(super.i);
       }
                      
  }

  Note: Parent could also simply look like this:

  public class Parent {
       int i = 3;
  }

  I see now that it is wrong to use the word 'object '.

  No, it isn't.

  they are there for the child to use, object

  That's where you're going wrong. Don't think about "the parent" and "child object. There is only one object, and it is mentioned by "this". You should think about members of the base or the classes and members of the (current) derived class. They are all members of the 'object', but the members of the base class can be hidden by the current members of class with the same name. That's all. Nothing too special about it.

  but they aren't the fields of it.

  Yes they are, but if they are hidden by local declarations that they are not visible to 'this', only to 'super '.

• Global variable among the jurisdictions in BPEL

  Hi all
  
  I have an FTP adapter in my bpel process. I read the header, tail, and then the data. The header, the tail and the data have their own instance. I would like to store the header data in a GLOBAL variable, so I can use these data in the instance of my data. So basically I need a global variable such that I can access when I'm in my instance of data. I don't want to write to a file or a database, is it possible to have a global variable among the many cases that retain the value and is not deleted when the instance is completed?
  
  Thank you

  Hello

  Instead of thinking about global variable why cant you think of the instance variable. See, all serialized instance BPEL variables you can use even no it is finished.
  But the thing is, you must have access to an instance of other BPEL processes BPEL variable. Simple. You can do this by BPEL process APIs.

  com.oracle.bpel.client.IBPELProcessHandle
  com.oracle.bpel.client.IInstanceHandle
  com.oracle.bpel.client.Locator

  These three classes will help you recover data from a single process instance. You can enjoy your condition.

• Dynamic release of variable size of dispatch class method array on FPGA

  I have a parent on the FPGA class that will serve as a model/framework for future code which is developed. I had planned on creating a class of the child and by substituting a few methods. The child class constant would have fallen on the schema so that the compiler would have no trouble knowing which method (parent or child) should be used (i.e. the parent method will in fact never used and will not be compiled with the main code). The output of one of the methods is a table. This table will have a different size depending on the application. I set the size of array as a variable. In the method of the child, there is no doubt about the size of the array so that the compiler must be able to understand. However, when I try to compile, I get an error on the size of the array. I can't figure a way around it. Any thoughts would be greatly appreciated!

  Thanks, Patrick

  

  The question implies the use of the register shift unitialized. On the first iteration of the loop, the value that comes out of the shift register is the default value for the data type, which is an empty array for a table (size zero). Therefore, unless wire you a table empty for the shift register to the right, the size of the array cannot infer statically by the compiler.

  To resolve this problem, you must feed an initial value for the table. Here, I just used the function of the matrix, but if you need to have a separate method that returns an array of default or the size of the array that will work as well.

  

• String to the Variable of the PSP?

  Hello

  I was hoping I could buid programmatically a variable path shared and then use the Reading Variable VI to read a value.

  Unfortunately, while I can convert a PSP Variable in a string, I can't do the reverse. The output of the string to the shared Variable VI is not recognized by the Reading VI Variable. I tried to convert it to a PSP Variable to help more class specific, but she would not allow LabVIEW or the other.

  

  Is there a way to convert a string to a variable that is shared by program readable?

  Thank you!

  DUH... I can use the Container Seach VI, as the beginning of my posted code... X_x * slinks away in embarrassment *.

• 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.

  Thank you very much

• [ACCIDENT] Crash when using ' equal to ' function of the String class

  When I use "equal to" function of the String class to compare 2 channels, the app will crash.

  Examples: pn_infopush.equals (PN_INFO_TIMER)

  I have to use "is" instead of "equal". The application will run normarly

  Does anyone have any idea who? I don't understand why.

  Thanks for your support!

  Hello

  Is there a chance that your variable can get a null value?

  Calling .equals not a null object can cause this.

  What type of exception you get? Can you provide a stacktrace?

• Extend the CellRenderer class

  I tried to extend the CellRenderer existing lightly change the behavior. However, I am having a very difficult time to do without actually looking at the CellRenderer class code. Its quite difficult to understand what methods override and what are the variables containing the required data. Is it possible to access the code? I do not use FlashBuilder.

  Thank you.

  Hey,.

  I wrote a sampling program that does what you need except im trying to figure out how to make the box event listeners. working on that now, but it's the code that should go you. I have class one main and one cell renderer. You got the general idea. I think the only thing that you missed the width and the implementation of the check box. When you use the this reference, you are referring to the cell itself and not the box. I think you might have mixed up who. This reference is to the current class as a whole and not only control access. Here is the code:

• Add a variable along the withQNetworkRequest

  Hello

  Is it possible to add a variable with the QNetworkRequest and receive this variable with the QNetworkResponse?

  Please help me

  Hello

  Yes, it is possible to transmit all information wrapped in QVariant using setAttribute whose attribute ID from QNetworkRequest::User to QNetworkRequest::UserMax.

  QNetworkRequest request(QUrl(apiURL));
  ...
  int offset = 12345;
  request.setAttribute(QNetworkRequest::User, offset); // primitive types are converted to QVariant automatically
  request.setAttribute(QNetworkRequest::User+1, someOtherVar);
  

  To get it back later:

  void ServerRequestManager::processResponse()
  {
    QNetworkReply *reply = qobject_cast(sender());
  
    int offset = reply->request().attribute(QNetworkRequest::User).toInt();
    ...
  
    reply->deleteLater();
  }
  

  I suggest to declare an enum for the ID attribute in the .h file:

  class ServerRequestManager: public QObject
  {public:  enum
    {
      AttributeOffset = QNetworkRequest::User,
      AttributeVar2,
      AttributeVar3
    };  ...
  };
