• Using the data binding on each button in a ToggleButtonBar

  Can someone tell me if it is possible to use the data binding on the individual buttons in a ToggleButtonBar and, if so, how?
  
  I want to be able to use the data binding for each individual button in the ToggleButtonBar 'enabled' property, but is not possible using MXML because the ToggleButtonBar takes a data provider to display labels for each button and, obviously, I can't set the "enabled" on the values of dataprovider property because they are not objects Button. For example, I'm not allowed to do something like this:
  
  < mx:ToggleButtonBar id = "tbb".
  toggleOnClick = 'true '.
  itemClick = "clickHandler (event)."
  creationComplete = "tbb.selectedIndex = 1" >
  
  < mx:Button label = "A" active = "{...}" / >
  < mx:Button label = "B" enabled = "{...}" / >
  < mx:Button label = "C" enabled = "{...}" / >
  
  < / mx:ToggleButtonBar >

  Ah! The ToggleButtonBar. Liaison. MXML. mysterious. Not obvious. But yes, we CAN do...
  First, you will need to get the buttons to toggle. Did you know that they are actually ButtonBarButtons? Once you get an instance of each of them, you can do the binding in MXML.

  Each button LINK below the ViewStack is bound to a ToggleBarButton.
  When you click a related button below, the LINK button above it will have its enabled enabled/disabled property. Then a link fires, setting the enabled property of the related ToggleBarButton.

  This example requires that you know advance how toggle buttons and buttons, you have, so it will not evolve well. Whenever you add a button, you will need to enter hard in the 'getButtons' function, which implements the ButtonBarButton instances. But if you have a known quantity of buttons, no problem.

• How to use the data binding on a cluster?

  Hello

  I just discovered the data binding and used it on some primitive controls/indicators. I love the cleanliness of the approach (no additional querying and son required!)

  Now, this page gives to think I can link a cluster with a shared too variable. However, when I right click-> properties, I see that the tabs appearance and Documentation (and I know that I did not accidentally choose an element inside the cluster, because (1) there is a typedef strict, and said the title of (2) 'The Cluster Properties' dialog box). Where can I find the data binding tab?

  Thank you

  Hi JKSH,

  What you're doing is possible if you make the file .ctl as the definition of type rather than a strict definition of type. With a strict definition of type all instances of the same .ctl file link that is why you cannot use data binding.

• Problems with the removal of the data binding Flex to use Air 14

  Hello

  I was wondering if anyone had an optimal solution to replace the Flex Air 14 data binding classes. I can't merge the Flex and Air SDKS more for all liaison managers need to be replaced. Everybody runs into this problem yet? Automated link generation and manipulation was the best feature of Flex and now that it's broken it creates huge problems for me.

  It is Air of mobile and desktop applications. They still build everything simply no work of event management.

  See you soon,.

  Pete

  I forgot that I myself have solved last Dec. So basically from what I can tell that the precompiler is either no [Bindable] conversions so you must manually create the getters and setters for your model when it changes. I hope this helps anyone who may run into the same problem. There is literally no documentation on this wheres.

  i.e.

  [Bindable]

  public var username: String;

  becomes

  private var _username: String;

  [Bindable (= "propertyChange" event)]

  public function get username (): String

  {

  return this ._serviceState;

  }

  public function set username(value:String):void

  {

  var oldValue:Object = this ._username;

  If (oldValue! == value)

  {

  This ._username = value;

  If (this.hasEventListener ("propertyChange"))

  this.dispatchEvent (mx.events.PropertyChangeEvent.createUpdateEvent (Thi, "username", oldValue, value));

  }

  }

  You must also make sure that what ever class contains this property implements IEventDispatcher and has the following functions:

  	//	Implementation of IEventDispatcher
  	//
  	private var _bindingEventDispatcher:flash.events.EventDispatcher =.
  		new flash.events.EventDispatcher (flash.events.IEventDispatcher (this));
  	/**
  	* @inheritDoc
  	*/
  	public function addEventListener (type: String, listener: Function,)
  									useCapture:Boolean = false,
  									priority: int = 0,.
  									weakRef:Boolean = false): void
  	{
  		_bindingEventDispatcher.addEventListener (type, listener, useCapture,
  			priority, weakRef);
  	}
  	/**
  	* @inheritDoc
  	*/
  	public function dispatchEvent (event:flash.events.Event): Boolean
  	{
  		Return _bindingEventDispatcher.dispatchEvent (event);
  	}
  	/**
  	* @inheritDoc
  	*/
  	public void hasEventListener(type:String):Boolean
  	{
  		Return _bindingEventDispatcher.hasEventListener (type);
  	}
  	/**
  	* @inheritDoc
  	*/
  	public void removeEventListener (type: String,)
  										Listener: Function,
  										useCapture:Boolean = false): void
  	{
  		_bindingEventDispatcher.removeEventListener (type, listener, useCapture);
  	}
  	/**
  	* @inheritDoc
  	*/
  	public void willTrigger(type:String):Boolean
  	{
  		Return _bindingEventDispatcher.willTrigger (type);
  	}

• Elements of the array and the data binding

  In Flex 1.5 elements of the array do not support data binding. Here is an excerpt from a document of Flex 1.5 older ( Chapter 18, data binding):
  
  

  Quote:
  The tables can be used in the bindings in the same way as other types of object. However, the elements of array do not pull a ChangeEvent when their value is changed, so that they can not be used as a binding source when running.
  Data binding does not, however, copy initial values in the request or the instantiation of the component, so the connections with their source as an array element will be set to the value of the element of array (only once, at initialization time) and will not be updated later if the array element is changed.

• Need information about the data included in the example for the inner race with flaws

  Hello

  There are several examples for fault detection in bearing (Vibration tool sets). I need more information about these data include:

  -Bringing its specifications

  -How to perform data acquisition

  -a link to the tutorial

  I came across this manual that shows how to use OATS envelope detection VI to perform detection of failures of bearings.

  http://zone.NI.com/reference/en-XX/help/372416A-01/svtconcepts/cst_speed_brg/

  It lists the specifications of turnover:

  • Inch diameter 0,2813
  
  
  • Primitive diameter: 1,1228 inch
  
  
  • Speed: 1 234 RPM

  It also goes to the list of characteristic frequencies determined by these attributes.

  The data acquisition is carried out by the use of an accelerometer and a tachometer. These devices measure the vibration and the rotation speed of the bearing data. Failure detection uses a method called detection of the envelope to look at the signals of the bearing and compared to signals of standard bearings to the discovery of flaws. You can learn more about the method of acquisition of data here:

  http://zone.NI.com/reference/en-XX/help/372416A-01/svtconcepts/fault_detection/#Envelope_Detection

  The first link is a tutorial on the detection of failures in the bearings. The end of the link provides the location of an example VI that may also be useful.

• Questions about the data reporting PowerCLI store

  Hello

  I have a problem with a script that I use and I'm looking for an idea on the problem.

  I have a script that gathers pretty much all the information on the virtual machine in my cluster. (Disk size, free disc, data store).

  Most of the time, it works very well. But there is something that bothers me little. It doesn't report the data store that each VM is linked to. It works for most, but on a select few, it's not.

  I wonder if there is something in my script which is the first cause, or if it is a question of VSphere.
  
  My script and the output is attached.
  
  Thanks in advance for the help.
  
  -Aaron

  I was able to get the warehouses of missing data as well.

  That's when the VMDK are stored on more than 1 data store for a specific virtual machine.

  In this case, the line

      $myDS = Get-Datastore | Where { $_.Id -eq $VM.Datastore}
  

  nothing will store in $myDS because $VM. Data store is an array of MoRefs.

  In fact you try to map the partitions in the guest OS with data warehouses that host the VMDK files.

  There is no easy solution for that I fear (there are number of threads in this community who are trying to do the same thing).

  I fear that there is no real solution for this problem

• Ask about the dates

  in the table below
  
  rm_limit
  
  as_on_dt limit_expiry_date OS ctry_id
  MARCH 13, 2011 5000 1 JUNE 12, 2011
  APRIL 15, 2010 6000 1 DECEMBER 5, 2011
  MAY 1, 2009 3 NOVEMBER 2011-156-2
  
  How can I write a query for the Sub statement:--
  
  If in rm_limit difference between the two being on the date and the limit_expiry_date > 180, but less than 365 days then the sum of all o/s (for the ctry_id in column 1)

  Apostrophes would make "180" in a literal string, so the answer is categorically NO!

  180 is a literal number - '180' is a string literal. Since you have a numerical value (the result of the subtraction of a date from a date), then you want to compare with a literal number.

  Do not compare the strings, numbers or vice versa...

• question about the date as output parameter

  x := to_date(to_char(sysdate,'dd/mm/yyyy'),'dd/mm/yyyy') ;

  And the output is   17-AUG-12 18-AUG-12   , instead of   17/08/2012   18/08/2012  

  The nls_date_format is: DD - MON - RR
  
  How can I get the output as dd/mm/yyyy format parameter.
  Thank you
  
  Published by: Smile on August 17, 2012 08:31

  Because your data type is date, the default output is the NLS_DATE_FORMAT.

  You can set NLS_DATE_FORMAT jj/mm/aaaa, but in reality, it would be better to do the following:

  Declare your out parameters as varchar2
  Convert date to be returned to your format of binding and value the more parameetrs to have this value

• about the data dictionary cache

  Can someone explain this statement?

  Yes, the statement is quite right but doesn't explain it well. I did a search and find Tom had discussion on it and claim the same. See the answer

  On a small test, with one user, you can count the latch accesses and see significant differences
  that may not appear to be terribly threatening . But with large numbers of users, the number of
  'clones' of objects with the same name in the same namespace and therefore on the same latch, goes
  up, and the time taken to search a chain can become a serious threat if everyone is trying to
  access some information about their verion of the 'same' object.  The scale of the problem is order
  n-squared with respect to the number of different users.
  

  Tom reviews the issue of scalability using the public synonym. As the number of users increases it would have more cloned copies Similarly, and they would be protected under lock and key, if of locking issues. I'll nedopil my previous post so that others don't get confused. And it was a kind of larning for me as well. Thanks for asking this question.

• Questions about the data form

  Hi guys,.
  just a general question: when we do a 'big' data form, it leads to overall performance problems or crashes. My question is, which is to limit the size of data? Is it the fact that Essbase has pull up a lot of data at once? Is it the fact that web applications are limited in quality? I would just get the thoughts of people on this general issue.
  
  Another General, somewhat vague question: IF I didn't make a huge data form, say just 10 departments, 400 accounts by cost on the lines and the period, some scenarios and years on the columns, it would help if I created a machine dedicated to planning web app? Increase RAM/CPU help?

  Take a peek on "My Oracle Support" there is an article "Hyperion Planning data form Design Considerations [ID 779502.1].
  I think that should answer most of your questions.
