• Help on parameters public static function

  Hello

  I have two functions in the same file, how can I use the first function as a default value in the second function.

  public static function get decimalFormatter1 (): {NumberFormatter

  //

  }

  I have try this:

  public static void secondFunction(param1:String,_param2:Int=0,_ _param3:Function=decimalFormatter1_):Array {}

  //

  }

  Error:-1047: unknown parameter initializer or isn't a compilation constant.

  Any ideas?

  Thank you!

  To work around the problem, you can use null as default, where null means "use the decimalFormatter1. You have to write something like

  public static void secondFunction(param1:String,_param2:int_=_0,_param3:Function_=_null):Array
  {

  trainer: function var = null;

  If (param3 is nothing)

  Formatter = decimalFormatter1;

  ....

  }

• Help with public static functions.

  Hey everyone, I worked on a problem for a while and have finally understood just wrong. Google is not helped me to find the right way, so I'm posting it here. I sort of understand what's wrong with my code, but I have no idea how to do right. I'm a total noob to AS3, this is my first project.

  I have a main FLA file called game.fla with nothing on the stage, starting with. The document class is Main.as (shown below). The main class is supposed to manage the switching between the preLoader, mainMenu and game itself. The preloader loads and the player must press play to go to the main menu. The main menu is controlled by MainMenu.as, which adds event listeners for buttons game, instructions and credits. At the present time, instructions and credits just draw responses. When you click on play, I want to remove the mainmenu (not a problem with parent.removeChild (this)); and add the game. This is my problem comes in. I can't say parent.addChild (game), because honestly, I don't know how (I need to set a variable in hand or MainMenu and must it be public, static, etc?). Simplicity seems to be a function called initializeGame() that I could simply call of mainMenu. Problem: I have to do a static function, which doesn't let me use addChild, removeChild or any other variable that I create. Could someone please explain how I could do this job (even if it means change my structure. "I would be happy to learn a better way to deal with this kind of thing). Also, on a side note: if I can't use the static function with add or remove a child, can I optimize the effect later? I want later in my game, that I would need to call functions between classes, on a button click, for example, that affect the scene (or objects in the scene). Can I do it another way? For example, by clicking on an icon of the video game card clip, I would map the movieclip to load. A function that could be described seems the best way to do it, but I'm sure he can otherwise. Thank you much in advance. My code is below.

  Could you please help me with this

  The same basic problem as in your previous thread. Confusion between creating an object from a collection/table of this object.

  Here's a basic example:

  SQL> create or replace type TScalar is object(
    2          id      integer,
    3          name    varchar2(10)
    4  );
    5  /
  
  Type created.
  
  SQL>
  SQL> create or replace type TArray is table of TScalar;
    2  /
  
  Type created.
  
  SQL>
  SQL> --// creating a scalar
  SQL> select TScalar( 1, 'John' ) as OBJ from dual;
  
  OBJ(ID, NAME)
  --------------------
  TSCALAR(1, 'John')
  
  SQL>
  SQL> --// creating an array/collection
  SQL> select
    2          TArray(
    3                  TScalar( 1, 'John' ),
    4                  TScalar( 2, 'Tom' )
    5          )                               as ARRAY
    6  from       dual;
  
  ARRAY(ID, NAME)
  --------------------------------------------------
  TARRAY(TSCALAR(1, 'John'), TSCALAR(2, 'Tom'))
  
  SQL> 
  

  So in your function, you will need to place objects in the collection.

  return(
      Rt_Type_Var(                      --// instantiate the collection
             Type_Rt ('STRT',var1_nri ,liq_Rt,'Stle' ,null)  --// place an object into the collection
      )
  );
  

  And use appropriate type names and the object. Poorly chosen and non standard naming conventions just add to the confusion.

• ORA 28817 PLSQL function returned an error. When the apex 4 2 instance access

  Hello
  
  I just upgraded from apex to apex 4.2 4.1. All is well except for this error I get when I try to access the parameter Instance on the App Admin (localhost/apex/apex_admin)
  

  ORA-28817: PL/SQL function has returned an error

  What could be the problem? How we solve this problem...
  
  I'm working on the 2012 Win server machine... apex 4.2 with earphone 2 deployed on Glassfish 3.1.2 apex.

  Hello Faye,

  We are already aware of this problem, even if it is not yet present on our Web page of problems known. The reason for this error is that the new facility replaces an instance to the scale encryption key. In the preferences of the instance which have been encrypted with the old value (the SMTP password and the password for the portfolio), the values are not valid after the upgrade and decryption causes this error. As a work around, you can use the apex_instance_admin package to replace the invalid passwords.

  The following code shows how the decryption throws ORA-28817:

  SYS@a411> select apex_instance_admin.get_parameter('SMTP_PASSWORD') from dual;
  select apex_instance_admin.get_parameter('SMTP_PASSWORD') from dual
         *
  ERROR at line 1:
  ORA-28817: PL/SQL function returned an error.

  ORA-06512: at "APEX_040200.WWV_FLOW_INSTANCE_ADMIN", line 239
  

  You can fix this by entering new password:

  PL/SQL procedure successfully completed.

• How to call a function of Instance inside a static function?

  Please help me.

  It's my static function: the function stillCallBack() is called successfully

  void MoreFunInPhilsCamera::stillCallback(camera_handle_t handle,
          camera_buffer_t *buf, void *arg)
  {
      MoreFunInPhilsCamera* inst = (MoreFunInPhilsCamera*) arg;
      emit inst->pictureSaved();
  }
  

  This is the warning:

  QObject::connect(this, SIGNAL(pictureSaved()), mTakePictureButton,
              SLOT(remove()));
  

  And I call the remove() function when the image is saved, but is not called

  void MoreFunInPhilsCamera::remove()
  {
      qDebug() << "I want to do something here, but this does not get called";
  }
  

  Check your signal connection. 'This' is the correct sender? is the slot to remove in your button?

• UiApplication - implementation RuntimeStore vs make Singleton object / Instance

  Hi all

  I ran into a lot of trouble with putting the UiApplication instance in the RuntimeStore for later retrieval of etc. other entry points.  I used the code of this resource (http://supportforums.blackberry.com/t5/Java-Development/Make-a-running-UI-application-go-to-the-back...)

  //register the alternate on first run
  RuntimeStore appReg = RuntimeStore.getRuntimeStore();
  synchronized(appReg){
     if (appReg.get(ID) == null) {
         appReg.put(ID, new Application(...));
     }
     Application MyApp = (Application)appReg.waitFor(ID);
     //then you have the app MyApp... return it or whatever
  }
  

  //check to see if the app exists, if it does, bring it to the foreground ...RuntimeStore appReg = RuntimeStore.getRuntimeStore();synchronized(appReg){   if (appReg.get(ID) != null){       Application MyApp = (Application)appReg.waitFor(ID);       MyApp.requestForground();   }}
  

  but UiApplication.getUiApplicationInstance (); Returns IllegalStateException.

  I have posted this before and have read that I might be better to create a Singleton instance of my UiApplication - can I get some advice about how to achieve?  The code I think I should reference is:

  import net.rim.device.api.system.*;
  
  class MySingleton {
     private static MySingleton _instance;
     private static final long GUID = 0xab4dd61c5d004c18L;
  
     // constructor
     MySingleton() {}
  
     public static MySingleton getInstance() {
        if (_instance == null) {
           _instance = (MySingleton)RuntimeStore.getRuntimeStore().get(GUID);
        if (_instance == null) {
  
           MySingleton singleton = new MySingleton();
  
           RuntimeStore.getRuntimeStore().put(GUID, singleton);
           _instance = singleton;
           }
        }
  
        return _instance;
  
     }
  }
  

  Thanks in advance for any help.

  Sorry, I have not looked at your code in detail.  Simon and I wanted to understand what your application was trying to do, rather than how he did.

  What you have described so far, there is no need to put your UiApplication in RuntimeStore.  Or do you need an AlternateEntry.

  So let us try to see if we can get your app working the way you want without steps.  I'm not saying that we will succeed, but trying, we and you will understand better opportunities.

  But note that this is only my opinion and here's how I would implement what you're trying to do, with a single application. I could be missing something.

  Let's start with the listeners.

  Some listeners require a current request - for example SystemListener.  Some are not, for example telephone headsets.  Treatment is kept on a warm reboot - for example, most of the non networking Threads will be suspended and restarted.  Some are not, for example, the ApplicationMenuItems are deleted.

  Assume that at least one of your listeners requires an Application.  In general, I do not use an Application, because I use SystemListener so that I can terminate my treatment in extinction and restart under power.  Which means that you must have an Application that is started automatically.

  Now, you also want to have an icon.  Since an icon is supposed to start a UiApplication, then let us do your started automatically asks a UiApplication.  To do this, you really push a screen, but it can also "requestBackground()", so that it does not actually appear in the autostart.

  The complication here is that some of this treatment actually impossible in the early stages of implementation service, so you need to check for

  ApplicationManager... inStartUp)

  and treat them accordingly.  There is an article that describes what I think.

  So now we have one started automatically UiApplication, who listens to the system start and stop and everything stops at the stop and everything begins to start.

  Now, when you click the icon, you will not actually start your application, you're just before an existing UiApplication.

  I think that so far we have matching your needs with one exception.  What happens if you want to restart your Application?

  We have already described code that stops the processing of your request - we will work this in extinction.  You just need to run that and then do a system.exit().  Now, when your hand is called, the next time that the user clicks on the icon, it will be started just as if it was during the auto-start and will go through the same initialization.  The trick is this time, you don't want to do the requestBackground.

  Here is the key.

  (1) an initialization routine that adds the headphones and starts the other treatment.  This will also push the initial screen.

  (2) an interrupt routine that stops the treatment started in the initialization routine

  (3) main routine creates the UiApplication and adds it as a SystemListener and enterTheDisplatcher.  It checks to see if the treatment is inStartUp.

  (a) if so it horizons application - initialization will be done by the power of SystemListener.

  (b) otherwise, it executes the initialization routine

  (4) SystemListener powerUp routine that performs the initialization routine

  (5) powerOff routine SystemListener which runs the completion routine

  (6) output in your application that runs the completion routine and then call system.exit().

  I think that if you implement these parts, you will have a DBMS which deals with the way you want, with no RuntimeStorage and no AlternateEntry.

• Public static long serialversion uid in doubt?

  Salvation in serializable classes we are declaring the serialversion as ' private public static long ' field. but when the object is serialized static values don't are not serialized, so at the other end when we are deserializing how the virtual machine works Java checks whether the serialvesrsion when it is serialized is the same as serialvesrsion in the class, when it is deserialized?

  It happened again, but not as part of a serialized instance.

• PhoneListener cannot access a public static vars initialized in the main thread

  Using the emulator (SDK 4.7, phone model 9500)

  I have a class PhoneListener defined and recorded, he gets the phone events without any problems. It's all public static public var that is initialized in the main thread is always null when it is examined in the context of the PhoneListener callback thread, when examined in the main thread or a son they are defined.

  I guess since the PhoneListener callbacks are called from a system thread, it cannot access the battery of my request - it seems correct? is this in any way about this?

  I tried Application.getApplication () .invokeLater (...), but validated all executable from the PhoneListener recalled suffers from the same problem.

  Thanks - Lindsay

  Exactly, that's what I was wondering - I found the answer according to the PhoneListener in the MIDlet . Now I store my UiApplication object in the running store and access them from the PhoneLister to publish objects on my main application via invokeLater.

  Thank you

• return the objects while maintaining the position on the page

  Is there a a way to return multiple objects at the same time while maintaining their position on the page without having to select each individually? For example, if I had a box of text at the top and bottom of a page, choose both and then reversed them, rather than the top text box swapping with that down they times remain in the same place but flip backwards?

  In Illustrator, you'd have the transformation of each command to do this, but in InDesign, you must use the function transform once again, which, if you're just flipping 2 objects records all the steps. But, let's say you want to return 16 objects as you describe... in place.

  Select one and choose object > transform > Flip (Horizontal or Vertical)...

  Now select the other 15 and choose object > transform again > transform again individually

• How a plugin method can return an object of properties (javascript)

  Hello

  With VC0 4.1, I have a plugin method written in Java. I would like that this method returns an object which Orchestrator (VCO) will see as an object of Properties javascript directly without passing by the serialization or other treatment...

  To do:

  -What class of java object my plugin method must return?

  -What should I use as return-type attribute when my method declaration in the VSO.xml file?

  "< script-the method name = 'myMethod' java-name = 'myMethod' return-type ="?">"

  Thanks in advance.

  Arnaud

  Hi Arnaud,.

  You're right, the object that returns your method should be Hashtable (I actually thought that properties should also be valid since it extends from Hashtable).

  Try with:

  public Hashtable {getInfosInProperties()}
  Hashtable retMap = new Hashtable ();

  retMap.put ("key1", "value 1");
  retMap.put ("Key2", new Long (2));
  retMap.put ("key3", true);

  Return retMap;
  }

  The vso.xml file is very good with "Properties". And you will get an object from the vCO scripting API to script properties.

  I hope it helps.
