To access the properties of the class one from another

• To access the class fields in another package (reflection)

  Hello
  
  Given that I have not found a section named "Reflection" in the forums, I guessed that this would be the place to post my question.
  
  I'm trying to implement a function called setField (field, value) in my classes using reflection. I have included this function in a base class so that its child classes could also use this feature.
  
  The base class looks like:

  public class Base {
  
      private Integer x;
  
      public void setField( String fieldName, Object value) {
          Class cls = this.getClass();
          
          while (cls.getSuperclass() != null) {
              System.out.println(cls.getName());
              
              try {
                  Field field = cls.getDeclaredField(fieldName);
                  field.set(this, value);
                  break;
              } catch (IllegalArgumentException ex) {
                  Logger.getLogger(JPT.class.getName()).log(Level.SEVERE, null, ex);
              } catch (IllegalAccessException ex) {
                  Logger.getLogger(JPT.class.getName()).log(Level.SEVERE, null, ex);
              } catch (NoSuchFieldException ex) {
                  Logger.getLogger(JPT.class.getName()).log(Level.SEVERE, null, ex);
              } catch (SecurityException ex) {
                  Logger.getLogger(JPT.class.getName()).log(Level.SEVERE, null, ex);
              }
              
              // if field not found in this class, check the superclass
              cls = cls.getSuperclass();
          }
      }
      
      public Integer getX() {
          return x;
      }
  
      public void setX(Integer x) {
          this.x = x;
      }
  }

  And then I have a class of the child:

  public class Child extends Base {
  
      protected Integer y;
  
      public Integer getY() {
          return y;
      }
  
      public void setY(Integer y) {
          this.y = y;
      }
  }

  So, basically, I need to get the type of features to work, i.e. to change a field in the child's class using the function available from the following base class:

  Child child = new Child();
  
  child.setField("y", new Integer(20));
  
  System.out.println(child.getY());

  This works when the base so the child classes are in the same package, but when they are on different packages, I get an error that looks like:

  java.lang.IllegalAccessException: Class teletutor.core.test1.Base can not access a member of class teletutor.core.test2.Child with modifiers "protected"
       at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:95)
       at java.lang.reflect.AccessibleObject.slowCheckMemberAccess(AccessibleObject.java:261)
       at java.lang.reflect.AccessibleObject.checkAccess(AccessibleObject.java:253)
       at java.lang.reflect.Field.doSecurityCheck(Field.java:983)
       at java.lang.reflect.Field.getFieldAccessor(Field.java:927)
       at java.lang.reflect.Field.set(Field.java:680)
       at teletutor.core.test1.Base.setField(JPT.java:27)

  I hope that I have identified my problem. Please suggest how I can get the desired effect.
  
  Thanks in advance.

• To access the EFS data from another disk using original certificates/keys

  I use EFS on a Workgroup XP - Pro, SP3 and have backed up keys.  I am trying to access the files on this disk now mounted in another machine (also SP3 of XP - Pro and in a working group).  I can load the certificates of the first machine in the second machine by double clicking it.  Once the certificates are loaded, how decipher you?  I get "Access denied" when I right click and try to decrypt the files on the original drive.  The MS help talk about designating a "File Recovery Agent", but this procedure seems to be to area of machines and gets a bit fuzzy for working groups.  BTW, I'm testing my file recovery process.  No data is at risk.  Can you tell me FAQ to decrypt a file on a disk that is moved to another machine using the original (REC & PFX files) encryption certificates/keys?

• To access the classes of CPP in qml.

  I have set up to access the classes of PCB in qml in two ways: -.

  1. create an attached object and the id of the class of CPP special and then access via the id.

  2. fix the CPP on the qml class before pushing the page using the setContextProperty.

  I wanted to know exactly when to use these two methods. There a difference in terms of scope and memory. Please explain.

  Great Question!

  Local objects:

  Attached to objects, or who inherit from classes of cascades, is the simplest way to expose c ++ objects that relate to user interface elements. This is what you use if you want this object to BELONG to this context qml. It is created by the qml context when createObject is called (your qml file is loaded) and destroyed with the user interface objects. You can create many of these objects, anywhere you need. However, if you want to expose global properties, it is probably not a good approach.

  The only time you would use objects attached to global stuff is if you expose a singleton class to allow qml set locations to manage signals (OrientationHandler is an example of that, without an OrientationHandler object, that you have nothing to connect).

  Global objects:

  Context properties can be considered global variables for a particular context, but with inheritance: context properties are passed to the contexts of the child. These objects are the PROPERTY of c ++, must be created before the creation of the object (createObject is called) and must remain valid for the lifetime of any context, they are placed in, but then destroyed is no longer necessary.

  The disadvantage of context properties changing them can be expensive. If you set a context property after the createObject call (that is to say an object exists that was created from this context), then all links in javascript in this context will be re-evaluated. However, you can mitigate this issue by exposing an object that contains the value as a property, so that links to branch on change of signals well if necessary.

  Inheritance is where shine context properties. There is a context root, which is in this context of default parent for new contexts. If you set a context property of the root context, it is available everywhere in any document qml. Here is an example of how do:

  QmlDocument::defaultDeclarativeEngine()->rootContext()->setContextProperty("app", myApp);
  

  Note: when I speak of createObject, I'm talking about QDeclarativeContext::createObject. It is called internally by QmlDocument::createRootObject.

  For more information on the Qml contexts, see http://qt-project.org/doc/qt-4.8/qdeclarativecontext.html

  For more information about the inner workings of qtdeclarative, see http://qt-project.org/doc/qt-4.8/qdeclarativeengine.html and http://qt-project.org/doc/qt-4.8/qdeclarativecomponent.html

• How to access the class of an Actionscript object

  Hello

  I'm trying to access the class of an Actionscript object as the Java method getClass().

  example:

  I have this class with a method "myMethod(clazz:Class)".

  public class Class2
  {
       ... 
       public function myMethod(clazz:Class):void
       {
         ...
       }
  }
  

  This other class:

  public class Class1
  {
      var class2:Class2 = new Class2()
  
      public function otherMethod(obj:Object):void
      {
            class2.myMethod(obj.????);
      }
   }
  

  Perhaps is it not possible?

  Thank you

  vdelbart

  There is no native to retrieve method class of an object, but this utility function should work for you:

  import flash.utils. *.
  import flash.system.ApplicationDomain;

  function getClass(o:*, appDomain:ApplicationDomain=null): Class
  {
  If (o == null | is a class o) {return o ;}

  result: var class = null;

  Try
  {
  var cName:String = flash.utils.getQualifiedClassName (o);
   
  If (appDomain! = null)
  {
  try {}
  result = appDomain.getDefinition (cName) class;
  }
  catch (err2) {result = null ;}
  }
  If (result is nothing)
  {
  Result = flash.utils.getDefinitionByName (cName) class;
  }
   
  }
  catch (Err) {result = null ;}
  Finally {}
  return the result;
  }

• ACCESS the same table in another file gives message as there is no...

  I'm working on a little game of shooting like a project to learn as3.

  I struggled a lot with the as3 syntax, but am willing to grit your teeth and hope that someday that light...

  the problem:

  I created three clips in a fla.

  I plugged 4 .as files to the fla:

  Bomber.As

  Bullet.As

  Kanon.As

  Shooter.As (connected to the phase of files / himself).

  All the behaviors of the mc are described in packages in their own connected .as file.

  I want to do a hitTestObject with "chips" and "bomber".

  
  

  as file f the ball inside, I make a table to store the bullets.

  
  

  When I want to access the same table in another .as file, I get a message there is no...

  
  

  Can anyone suggest a solution...?

  any help is very appreciated!

  If the bullet.as file is supposed to be for a ball, and you intend to have more than one ball in action at any given time, so you probably don't want this table in the class bullet.as in any case.  If the shooter file is the actual game file, then I have the file of shooting game in charge of the creation of new instances of the ball, and that is where I keep track of them in a table and their test against the bombers.

  Hello

  No.; If the operating system on the other came computer preinstalled (Dell, HP, Acer, etc.) you can't use it on another PC.

  If the laptop/computer came with preinstalled Windows operating system (Dell, HP, Acer, etc.), this product key provided with your computer/laptop to the OEM license preinstalled and is not transferable.

  OEM license/product key (systems of operating pre-installed on Dell, HP, etc.) is related to the first machine it is installed on and dies when dies of this machine.

  Only retail Operating System license that you buy and install yourself, are allowed to be transferred to another machine.

  And retail licenses also can be installed on a machine at one time.

• Access the class from the loaded module

  I have this in the main application and I the public variable test in the module. The problem is that I don't know how to access it properly.

  public

  var fontsModule:IModuleInfo;

  public var FontsClass: Class;

  public

  function initApp(evt:FlexEvent):Sub

  {

  fontsModule = ModuleManager.getModule ("modules/fontsBG.swf");

  fontsModule.addEventListener (ModuleEvent.READY, fontsLoaded);

  () fontsModule.load

  new ApplicationDomain (ApplicationDomain.currentDomain), null , null , moduleFactory);

  }

  public function fontsLoaded(evt:ModuleEvent):Sub

  {

  FontsClass = fontsModule.factory.create)

  as Class;

            trace ()' HERE: "(+ FontsClass.test);". "

  }

  If I replace the class with the name of the 'FontsBG' class actions script in this example, everything would work, but the main swf file size goes from 100 to nearly 400 kbs when the fontsBG.swf file is 67 kbs. So I'm certainly not doing it right.

  So the question is: what is the correct way of loading the modules and using their properties and functions - through the class or interface and how it's done? Please set up a small code example so I can get the concept of base as well as the readers of this thread.

  Thank you!!!

  (3) again, you will need to use a shared interface or a common base class.

  Most people put the UI widgets in a module and they all extends UIComponent

  You can reference them as UIComponents.  If they need to access other

  Properties and methods, they define an interface.

  (1) my guess is that the button does not know what a module with embedded

  fonts loaded and don't refresh to use.  Normally, you would

  wrap styles in the module with the fonts, and then set styleonce

  the module is loaded.  In this case, you specify MyriadPro as the

  CSS font family and he would set via setStyle once the module is loaded.

• Possible to access the listener function in another class?

  I want a listener on a tween on the document class when it is finished, it goes to the listener of its child function, but I don't know how.  I thought it would be just a case of document.functionName, but it is throwing an error.

  I've got:

  treeWidth_tw.addEventListener (TweenEvent.MOTION_FINISH, Bauble.startFade) in the parent document

  and in the mc of the child:

  public void startFade(evnt:TweenEvent) {}

  fadeTween = new Tween(this,"alpha",Regular.easeIn,0,1,3,true)

  }

  
  
  

  I get the error message:

  1061: call to a startFade method maybe not defined through a reference with static type class.

  Is the class trinket or is it and the instance name?

  Generally, class names begin with a capital letter and instance names are tiny. So I guess that bauble is the name of the class.

  In this case Flash expects a static class called startFade method. So to you class file you defined:

  public static void fadeStep()

  or is it defined as an instance method?

• How can I access an e-mail account on TB from another computer without delete/modify how the other account is configured

  I want to be able to access one another e-mail account is set up as a POP account on TB, but I don't want to change the way the other e-mail account is configured. My colleague and I often need to access each others emails. Is it simply a matter of adding the e-mail account on my computer as a POP, without moving his e-mails? Or it would require to change his account to IMAP? When I created his account of TB, I did a POP so there is no messages on the server at the moment. What I don't want, it's for his e-mails from his computer to mine.
  (He's new to TB and making crazy him - I already did that when I went it to Outlook)

  Thank you

  Is it simply a matter of adding the e-mail account on my computer as a POP

  Yes. And don't forget to check the option to leave messages on the server before accessing the account.

  That said, I think it's a very bad idea to share an account like this.
  Note that this will give you access to on behalf of your colleague.
  In addition you do not store only your own messages on your computer, but also messages of all your colleague.
  The same is true for him if he does the same thing.

• Need to access the user accounts from previous installations

  I am running Windows XP Pro, and I have installed new software.

  When I have it ran for the first time my PC crashed. Now, whenever I try to load it up it just keeps restarting before you get to the login screen. Safe mode does not help you, or doesn't last known good configuration. There is no recovery point recorded.

  I searched online for help and tried to repair the Windows version by inserting the CD and choose 'Repair', but there is no repair option. He wants me to install a new version of Windows on the partition, which, from what I understand, going to wipe my user accounts. It would be a big problem, as I have a lot of data out there that is very important for me who is not saved. My fault, still backward, etc. No not after the sympathy, just stating the facts!

  I also have Windows XP 64 is installed on a separate partition, and I loaded this up to see if I can see the user account I want to access. I can. But I can't access it because it is password protected, and it just comes up saying 'access denied '.

  So, how do I gain access to this user account? Doing anything to the working version of XP64, either by repairing the other partition inactive?

  All welcome, no matter how much of a long shot it is advice. I'm getting desperate!

  Thanks in advance.

  Hi Malkeleah,

  I had real problems trying to get Knoppix to work. I downloaded on my laptop, then had to put on a USB key to burn on the PC with Win 64 on (portable DVD player is read-only), but I couldn't do burn. I kept of burning errors using the built-in burner after first unpacking the ISO on the laptop (no support ISO native in Windows XP), or when I tried to install on win 64 the system burning software I got error messages saying: the software wouldn't run as soon as I clicked to install it. And Yes, I checked that I was using the software compatible 64-bit! No idea what it was, the 64-bit version has never really been used, not even well why it is installed.

  In any case, after that much hitting my head on the office followed a couple of pints in pubs, I managed to find another way around this problem, which was to take ownership of the files according to the instructions on the Microsoft Web site:

  http://support.Microsoft.com/default.aspx/KB/308421

  It worked wonderfully for me, and I have been able to support Windows 64-bit, re - install XP 'normal' and then appropriated again under that. 2 files come with errors and would not sell the property, but they were not even remotely important if everything is good. I got literally thousands of other files that flies over without any problems.

  In any case, thank you for taking the time to help me, I'm sure that your method would have worked if I had been able to create a CD (I would have posted off the coast for one if everything else has failed because they will send one in the world for any $2 IIRC), but for someone else who did a search and found my ad the above that I mention is worth a go as an alternative method.

  And no, I didn't have the encrypted files. Just locked the account of some simple password protection.

  Thanks again,

  Chris.

  Hello

  You can not access the system from the BIOS recovery.

  F8 boot Options is your hope, but you say that they do not work

  You need a Microsoft DVD to do a startup repair, or a restoration of the system, thanks to this Guide.

  Manufacturers recovery disks normally do not have Service Options; they are normally a relocation to the factory only settings option.

  Here is the guide to repair Options using a Vista DVD from Microsoft.

  If a friend or a work acquantance of yours has one, you can borrow and use it for repairs.

  If you do not or can not borrow a Microsoft DVD there is a download of a file ISO of Vista Startup Repair available that you can put on a Bootable floppy to make the above startup repair and that the method is recommended by a large number of posters in these Forums.

  Unfortunately, you have to buy it.

• To access the backups Time Machine another computer

  I have spent a good hour looking for a solution to this problem, but have developed empty-handed.

  If I understand correctly, backups of access from another Mac time Machine, I need to connect the backup drive to another Mac and select "Browse Other Time Machine disks... "in the Time Machine dock menu and choose the drive.

  The backup drive appeared as expected and I clicked on "Use selected Disk" to enter the time Machine.

  At this point, the computer between what seems to be Time machine, but shows a Finder window to the hard disk of the computer rather than the backup drive and shows not all dates before "today (now)."

  A thread has suggested that I open a Finder window and select 'Computer' in the menu to reach before the opening of time Machine. It did not work.

  Another thread has suggested that I have use the Migration Wizard rather to recover files and folders, I need. This is not ideal, but I tried it anyway, the result being that the Migration Wizard app remained "Looking for source...". "without finding the backup drive.

  Before formatting my drive on the original Mac, I had checked for if ensure that I could access the Time Machine backup while it was plugged into the backup drive (which he successful well).

  I use the latest version of El Capitan 10.11.6 on a MacBook Air (mid 2011). Backup is a MacBook Pro (mid-2010) who ran as El Capitan.

  I would appreciate any other suggestions!

  So, I discovered the solution, which has been in a simpler way that I expected. Before opening, Time Machine, it is necessary to find the sparsebundle Disk Image in the backup disk in the Finder and open it with "DiskImageMounter." Then, you must select "Computer" in the Finder menu reach before choosing the option "Browse Other Time Machine disks... "menu to the dock of time Machine. The first finder window it shows in the Time Machine view still belongs to the computer, but now it shows the previous backups, who are all from the backup drive!
