• Implementation of a simple alert high CPU in vFoglight

  Implementation of a simple CPU alert for VMS alert when the CPU is greater than 95%. I use the syntax is the following:

  If (> 95 #cpuUtilization #)

  Returns true;

  otherwise return false;

  Get the following error when I run the query:

  com.quest.nitro.service.sl.interfaces.scripting.ScriptingException: com.quest.nitro.service.sl.interfaces.scripting.ScriptMalformedQueryException: bad request: java.lang.IllegalArgumentException: Type ' foglight - 5:VMWVirtualMachineHostCPUs:10' doesn't have a property with the name 'cpuUtilization' - beginning of the script - if (#cpuUtilization # > 1) return true; otherwise return false; --end of script--

  Is there another variable (#cpuUtilization #) I need to use for the use of the processor.

  You try to set an alert on the virutal machine CPU usage? Is there a problem with the release of the Inbox rule?

  It is a rule for this 'Virtual Machine CPU Utilization VMW"and you can change the threshold. It is in the form of variables (VMW:virtualMachineCPU.warning, VMW:virtualMachineCPU.critical) if yo uare not happy with the settings.

  The rule checks usage under $scope.hostCPUs

• Add implementation of a serializable class Externalizable already

  Hello
  
  I have a class that implements Serializable. It has methods "private Sub writeObject (ObjectOutputStream)" and "private Sub readObject (ObjectInputStream). Everything works.
  
  I need to change the class to implement Externalizable.
  Can / should I just change the methods writeObject and readObject 'public Sub writeExternal (ObjectOutput)' and 'public Sub readExternal (ObjectInput)?
  Or do I keep the writeObject and readObject methods and adding new methods, writeExternal and readExternal with the same implementation methods?
  
  This article makes it sound like I just have writeExternal() calling writeObject() and readExternal() call readObject().
  http://Java.Sun.com/developer/technicalarticles/programming/serialization/
  
  Right now, I like the idea of adding methods and calling existing methods. Ideas or corrections?
  
  Thank you

  If a class implements the Externalizable, serializable (writeObject() and readObject()) ignored methods are because writeExternal() and readExternal() are used?

  Yes, writeObject and readObject are completely ignored. In addition, if your impl of writeObject/readObject consumed one of the methods by default (defaultReadObject, defaultWriteObject), you will have to manage yourself in readExternal/writeExternal methods. essentially, when you create an Externalizable object, you assume all responsibility for reading/writing the object.

• Simple class and the display list

  I have a very simple code for a class:

  package
  {
  import flash.text.TextField;
  import flash.display.Sprite;
  
  SerializableAttribute public class Greeter extends Sprite
  {
  public void Greeter()
  {
  var txtHello:TextField = new TextField();
  txtHello.text = "Hello World";
  trace ("HI");
  addChild (txtHello);
  }
  }
  }

  The above file is saved as Greeter.as say folder C:\test

  I then create a Fla file, named test_display.fla (recorded in C:\test) and its content is:

  import Greeter;
  var tt:Greeter = new Greeter();

  Now, the output window displays salvation because of the trace statement but should show the addChild method

  Hello World in the Flash movie, but it does not work. The only way to get Hello World to the Flash movie

  is to change the test_display.fla to:

  import Greeter;
  var tt:Greeter = new Greeter();

  addChild (tt);

  In other words, I have to use the method addChild twice (once in the Greeter.as and once in test_display.fla)

  to get the Hello World to be displayed in the Flash animation. Does anyone know why this is so?

  Because each DisplayObject must be explicitly added to the display list. Text field is on the display of the banner of host list and in order for him show that he has relatives (Greeter) should be added to the other display list-timeline in this case).

  In other words, it is insufficient to simply create an instance - it must be added via addChild. It begins to make more sense if you remember that not all classes are DisaplayObjects and can perform other that just display objects functions.

• Make a simple class, I need a little advice

  I have a simple scroll bar class, but it does not work. Anyone can point out what I'm doing wrong?
  I have a movieclip with movieclip instances track_mc and drag_mc to the breast. I create my new class and pass the name of the host element.
  In the constructor I can trace the correct clips and drag_mc gets his onRelease function.
  When I click it the startDrag() does not work and the drag() works traces undefined for drag_mc, why is this, what I'm missing here?

  > he drag() traces undefined function
  Problem with simple range. Inside of the callback functions, the members of the class are out of reach. To resolve, use the import statement:
  Import mx.utils.Delegate;

  and then use:
  drag_mc.onPress = Delegate.create (this, drag);

  Without the import statement:
  drag_mc.onPress = mx.utils.Delegate.create (this, drag);

• FMS automatic disconnects when you use a class

  I am trying to implement a very simple class that will create an instance of the NetConnection object and connect to the FMS server. However, the customer connect then disconnect immediately when the swf file is published. My code is as follows...
  
  The FLA code:
  Import _includes.*;
  var obj_conn:Conn = new Conn();
  obj_conn. Connect();
  
  Code Conn.As:
  _includes class. Conn
  {
  public void Conn()
  {
  }
  
  public void connect()
  {
  var nc:NetConnection = new NetConnection();
  NC. Connect ("rtmp://localhost/classtest");
  }
  }
  
  
  Please note that the connection works fine if I just create a NetConnection instance on the FLA itself variable in the timeline. Any suggestions/help would be appreciated!

  He thinks that is because you use the local variable: your variable is deleted at the end of the connect() so your NetConnection will close its doors at the same time.

  Try this:

  Code Conn.As:
  _includes class. Conn
  {

  private var objNetCon:NetConnection;

  public void Conn()
  {
  }

  public void connect()
  {
  this.objNetCon = new NetConnection();
  this.objNetCon.connect ("rtmp://localhost/classtest");
  }
  }

• Unusual use of the static getInstance factory class definition interface

  This question is prompted by a recent new to Java forum question asking about the differences between Interfaces and abstract classes. Of course, one of the standard things mentioned is that interfaces can't actually implement a method.
  
  One of my former clients, the 500 group, using interfaces as class factories. The interface defines a static class of the pubis with a static method public, getInstance, who is called to generate instances of a class that implements the interface.
  
  This architecture was very object oriented, made good use of polymorphism and worked very well. But I have not seen this used anywhere architecture elsewhere, and it seemed a bit convoluted.
  
  Here's a version of 'Nick' of the model of the base interface and use

  -- interface that defines public static factory class and getInstance method
  public interface abc {
      public static class FactoryClass
      {
          public static abc getInstance ()
          {
              return (abc) FactoryGenerator(new abcImpl(), abc.class);
          }
      }
  }
  
  -- call of interface factory to create an instance
  abc myABC = abc.Factory.getInstance();

  1. each major functional area ('abc' in the above) has its own factory of interface
  2. each major functional area has its own implementation of this interface class
  3. There is a generator (FactoryGenerator) that uses the interface class ("abc.class") to determine the implementation to instantiate classes and return. The generator class can be configured at startup to control the actual class of return for a given interface.
  
  I should mention that the people who designed this whole architecture were not novices. They wrote very sophisticated multi-threaded code that rarely had problems, was high performance and was easy to extend to add new features (interfaces and classes of application) - pretty much plug-n-play with little, if any, side effects affecting existing modules.
  
  It is a process of best practices of factory design classes and methods? Please provide feedback about the use of an architecture like that.

  The way he explained to me at the time is that the interface uses standard naming conventions and acts as a template to make it easy to clone new modules: just change 'abc' to 'def' in three places and write a new class of "defImpl" which extends the interface and the new interface and the class can simply 'plug in' to the framework.

  There are in your pseudo code code in the interface to build a new abcImpl(). This deployment of a new plant means a change of this interface. If this is what is meant, it is poor. See java.util.ServiceLoader for an example of the right way to do it, with the implementation classes named in an external file.

  The generator class might use the information, if provided, to provide a new version of the class which would extend this default class.

  I hope so, but who is not exposed by your pseudocode.

  I never saw any 'Java' pattern that looks like this or any model where a contained interface a class.

  There are several examples in the JDK. Unfortunately I can't think of them right now. ;-)

  It seemed really complicated for me

  Me too.

  and it looks like the "versioning" aspect could be accomplished in a much simpler way.

  Indeed, he can see java.util.ServiceLoader.

• simple error in CQL

  I'm trying to implement a very simple POC program. CEP is composed of the following element.
  1 Jms adapter named MarketEventInputadapter, which reads data from a simple queue message card.
  2. a channel named MarketEventInputchannel input.
  3. a processor named MarketEventprocessor containing CQL "<!" [CDATA [select * from MarketEventInputchannel [now]]] > "."
  4. a MarketEventOutputChannel output.
  5. one event MarketEventBean bean
  
  while trying to deploy I get the error like:
  < error > < deployment > < BEA-2045016 > < the context of the "My_CEP" application could not be started. Not able to initialize the component 'MarketEventprocessor': event property defined in the [ExampleQuery] [cTimeStamp] query must exist in the [MarketEvent] event type. Consider using the term ' cTimeStamp LIKE...' in the query.
  
  I use MarketEvent.java:
  package com.bea.wlevs.example.algotrading.event;
  
  public class MarketEvent {}
  
  TimeStamp Long private;
  symbol of the private channel;
  price Double private;
  volume of Long private;
  private Long latencyTimestamp;
  
  /**
  * @return the latencyTimestamp
  */
  {} public Long getLatencyTimestamp()
  Return latencyTimestamp;
  }
  /**

  */
  {} public void setLatencyTimestamp (Long latencyTimestamp)
  this.latencyTimestamp = latencyTimestamp;
  }
  /**
  * the timestamp @return
  */
  public Long getTimestamp() {}
  Back to TimeStamp;
  }
  /**
  @param timestamp the timestamp to set
  */
  {} public void setTimestamp (Long TimeStamp)
  This. TimeStamp = TimeStamp;
  }
  /**
  * @return the symbol
  */
  public String getSymbol() {}
  return the symbol;
  }
  /**
  @param symbol the symbol to define
  */
  {} public void setSymbol (symbol of the chain)
  This.Symbol = symbol;
  }
  /**
  * @return the price
  */
  {} public Double getPrice()
  return of the price;
  }
  /**
  @param price TBD
  */
  {} public void setPrice (Double rate)
  This.Price = price;
  }
  /**
  * @return the volume
  */
  {} public Long getVolume()
  return of volume;
  }
  /**
  @param volume the volume to set
  */
  {} public void setVolume (Long volume)
  This.volume = volume;
  }
  }
  
  I also use MarketEventBean.java:
  
  package com.bea.wlevs.example.algotrading;
  
  import com.bea.wlevs.ede.api.StreamSink;
  import com.bea.wlevs.example.algotrading.event.MarketEvent;
  
  / public class MarketEventBean implements StreamSink {}
  {} public void onInsertEvent (event object)
  If (event instanceof MarketEvent) {}
  MarketEvent marketEvent = (MarketEvent) event;
  
  System.out.println ("price:" + marketEvent.getPrice ());
  
  }
  }
  
  }
  
  Can someone give an idea about the cause of the error?

  The cause of this issue is the event property named timestamp. Timestamp is a CQL keyword and there seems to be a bug in the way we deal with the properties of event names that are keywords CQL.

  One way around this problem is to use a different property name; for example, Sub. Take us a look at the bug and fix it. Can you open a service request so that it will follow up? Thank you

• Simple CVI user interface changes

  I'm changing the UI Simple CVI (TestStand 4.1.1) and would like to have a similar functionality using the SequenceCombo and the SequenceView box as the complete UI featured the sequence list box and the box of SequenceView (STEPLISTVIEW).  So that when I select a sequence in the drop-down list the steps are given in the SequenceView box.

  Thank you

  John

  Hi John,.

  The implementation is quite simple with TestStand Manager controls. Simply open the CVI Simple IO code, and paste the following in SetupActiveXControls() function call:

  tsErrChk (TSUI_SequenceFileViewMgrConnectSequenceView (gMainWindow.sequenceFileViewMgr, & errorInfo, gMainWindow.sequenceView2, 0))
  

  .. .or sequenceView2 in three parameter is a reference to a secondary control of SequenceView on the main Board (like Sylvie mentioned). Fortunately, the TestStand SequenceFileView Manager manages all the necessary calls to update area SequenceCombo selection-based control of SequenceView.

  The source code is attached.

• LVOOP: Common accessor for the child classes?

  I am reletively new to LVOOP and OBJECT oriented programming in general. I used very simple classes as a replacement for clusters several times, and now I have an architecture intended to convert most of my code into classes, dynamic distribution screw and similar.

  However, I run in to an issue, which basically boils down to laziness: I really don't want to do a lot of the same dynamic send screws I want to have a VI parent to be able to write a piece of data common to all children. Preference gives an error if the child does not have this data element.

  I guess it's quite similar to dynamic distribution, but without having to write a DD VI for each class.

  Is it possible to have the VI parent to access the data of the child? If so, how?

  Here is an example of my hierarchy:

  Test.lvclass (parent)

  DC_test.lvlcass (data: test number, 2D, time stampresults)

  Transfer_Curve_test.lvlcass (data: results of tests settings, 1 d, timestamp)

  Breakdown_test.lvlcass (data: test number, 3D, timestampresults)

  ... 28 another test

  As you can see, the data type only common between them is the timestamp. I want to be able to use a VI in the parent class to write data in the child class.

  You have it backwards autour.

  The data that is common belongs to the parent class, not the class of the child.

  Data that are not common may not be processed by the parent class and must be transformed by the child class.

  You don't need to CREATE truly dynamic shipping screws for a common data type.  If you just don't set the VI at all, it will be called the parent instance.

• This VI belongs to a class of LabVIEW. No part of the class is executable at this time, because one of the screws is missing. However, I'm not missing a vi

  I have only 1 vi and its not to miss.  1 vi advertising the library owner has blocked enforcement of the VI.  The class has the error "this VI belongs to a class of LabVIEW. No part of the class is executable at this time, because one of the screws is missing. Find Member missing screws on the disk and load them into memory or remove them from the definition of class in the project tree. »

  But there is only 1 member vi! ??

  I had a lot of other vi through this class, but somehow this class failed with this error.  I removed all vi directory and the definition of class and just done re the a vi reviewer and still have the error message.

  I enclose my ridiculously simple class.

  I have other classes that work very well, but somehow it seems to have gotten sloppy.  I really need to understand what happened here and how get/avoid this error, or I wouldn't have the confidence to develop large scale applications using classes.

  In other words... Help, please!

  Your class contains two screws a VI is called Untitled 1 and the other reading Max level.vi.

  Maybe this could happen (not tested) as follows. You have created two screws and saved one of them as reading Max level.vi. Then, you have saved the class. When the classyou of fence chose not to save untitled 1 and not to save the class.

  How to fix it. Open the class file with any text editor. Remove all lines between and including the following lines in the file:

  
     

  This will fix your class.

• How to implement the ScreenUiEngineAttachedListener Interface?

  How to implement the ScreenUiEngineAttachedListener Interface? It is somewhat a mystery reading through the API.

  I have a class that implements ScreenUiEngineAttachedListener:

  public class UiListener implements ScreenUiEngineAttachedListener {
    public void onScreenUiEngineAttached(Screen screen, boolean attached) {
    }
  }
  

  Then I have a class MyScreen which extends from screen and has two methods:

  public void addScreenUiEngineAttachedListener(ScreenUiEngineAttachedListener listener) {
    super.addScreenUiEngineAttachedListener(listener);
  }
  
  private void removeScreenUiEngineAttachedListener() {
  
  }
  

  • What is the correct positioning of everything?
  • Can I define an instance of UiListener and pass in the addScreenUiEngineAttachedListener?
  • How to remove UiListener in removeScreenUiEngineAttachedListener?

  You will need:

  • an instance of your UiListener - probably a static member inside your UiApplication;
  • a method that allows to retrieve the reference to this instance of UiListener;
  • a call in your constructor for the screen at addScreenUiEngineAttachedListener (yourApplication.getUiListener ()) or similar;
  • potentially a call within your onScreenUiEngineAttached (attached screen, boolean) routine, the branch (attachment is false) : screen.removeScreenUiEngineAttachedListener (this);

  However, all this is too much work for no gain. Just override protected void onUiEngineAttached (boolean attached) in your screen class and make your logic there - all members of your class are accessible and all the code is placed where it belongs.

• Duty slot in my sensor signal connection related problem class.

  I fanned simple class based on the NDK documentation found here - http://developer.blackberry.com/native/documentation/cascades/device_comm/sensors/

  But in my case signals do not plug on slots and returns always false. I was just wondering what I did wrong? Looks all logical.

      // aren't affected by device orientation.
      //m_CompassSensor->setAxesOrientationMode(QCompass::FixedOrientation);
  
      // If any Q_ASSERT statement(s) indicate that the slot failed
      // to connect to the signal, make sure you know exactly why this
      // has happened. This is not normal, and will cause your app
      // to stop working
      bool res = connect(m_Accelerometer,
                         SIGNAL(readingChanged()),

                         SLOT(compassReadingChanged()));
      Q_ASSERT(res);
  
      // Since the variable is not used in the app, this is
      // added to avoid a compiler warning.
      Q_UNUSED(res);
  
      m_CompassSensor->start();

  Hello

  I'm building a custom menu system and I'm using an anonymous inner class with a method of execution. Can you tell me how to run the run method... thx... Here is a code example.

  MenuItem menuItem = new MenuItem ("priority", 10) {}
  public void run() {}
  setTitle ("Hello World! l ») ;
  }
  };

  Thanks in advance

  Simon, I thought about it... I had to implement Runnable in the class, which allows me to call the method run like this:

  . run() menuItem;

  Thanks for your patience, I know I'm not the sharpest tool in the shed.
