View event processing

I don't get treatment at work of the event to view. I looked through most of the documentation for Flex 2 and Flex 3 and many of the Flex books to try to get this working. I am just trying to have a vision to create an event with additional information, go to another view that intercepts and then uses the event information. My simple exploratory code is:

View1 - view initiator:

<? XML version = "1.0" encoding = "utf-8"? >
"" < mx:Canvas xmlns:mx = ' http://www.adobe.com/2006/mxml ' creationComplete = "init ()" >
< mx:Metadata >
[Event (name = "monitorChange", type = "events. MonitorEvent")]
< / mx:Metadata >
< mx:Script >
<! [CDATA]
Mx.events import. *;
How to import events. MonitorEvent;
[Bindable]
private var test: String = "initial".
private function init (): void
{this.addEventListener (MonitorEvent.MONITOR_CHANGE, monitorChange);
test = "add an event listener.
}
private void monitorChange(event:MonitorEvent):void
{test = "add event monitor:"+ String (event.ct); "}
}
private function startEvent (): void
{var e:MonitorEvent = new MonitorEvent ("monitorChange", 5);}
this.dispatchEvent (e);
}
private function clearLabel (): void
{test = 'clear the listener';
}
[]] >
< / mx:Script >
< mx:Button label = "Event" left = "300" top = "8" click = "startEvent ()" / >
< mx:Button label = "Clear" left = "380" top = "8" click = "clearLabel ()" / >
< mx:Label text = '{test}' left top = "700" = "8" / >
< / mx:Canvas >

VIEW2 - notice of receipt:

<? XML version = "1.0" encoding = "utf-8"? >
"" < mx:Canvas xmlns:mx = ' http://www.adobe.com/2006/mxml ' creationComplete = "init ()" >
< mx:Script >
<! [CDATA]
Mx.events import. *;
How to import events. MonitorEvent;

[Bindable]
private var test: String = "initial".

private function init (): void
{this.eventTest.addEventListener (MonitorEvent.MONITOR_CHANGE, monitorChange);
test = "add an event listener.
}
private void monitorChange(event:MonitorEvent):void
{test = 'add an event monitor';
}
[]] >
< / mx:Script >
< mx:Label id = "eventTest" text = "{test}" left top = "700" = "8" / >
< / mx:Canvas >

CUSTOM EVENT:

package events
{import flash.events.Event;}
SerializableAttribute public class MonitorEvent extends Event
{
public void MonitorEvent (type: String, ct:int = 0)
{super (type);
This.CT = ct;
}
public static const = "monitorChange" MONITOR_CHANGE:String
public var ct:int;

override public function clone (): event
{return new MonitorEvent (type, ct);}
}
}
}

The event is started in View1 and treated but is not picked up in VIEW2. I see that the listener in View2 is loaded, but nothing don't get going in VIEW2 began in View1. I'm sure that I'm something stupid or do not see the obvious. I would be happy to help get this work since this seems to be the easiest to pass information between asynchronous events in an application and keep all Sync.

I think I found the missing piece. The event spreads upward from the original view, it only goes to the application tree. Do not only none of the lower branches of the tree. 2 points of view were on parallel branches and so the 2nd view has never responded to the event. The solution is a receiver be respond to the event top of 1st who will carry out the intervention in the 2nd view. In my case, the parent of View1 and VIEW2 are the same. A parent listen View1 event and respond by calling routine appropriate in VIEW2.

Simple concept, but I missed all the reading.

    Hello.
    Complex event processing (CEP) server is a complete product.
    Business Event/event delivery network is just a part of email/event of the SOA Infrastructure component.

    So, if you are interested on the correlation of events from different sources, high performance on the analysis of these events plus operations among the data generated on these events, CEP is your option.
    Hope this helps

  • BPEL and CEP (Complex Event Processing)

    Is there a possibility to integrate the Complex Event Processing with BPEL?

    For example - if some event occurred one to the CEP-part BPEL-part will be called.

    I'm not sure I understand your question, BPEL and CEP jms support out of the box, via adapters. When you install BPEL, the client API brings with it...

  • View or process data acquired by NI 5732

    Hi all

    I have a scanner high-speed NI 5732 works with NI SMU 7962R. I need to acquire data at high frequency and the process/view it online if possible. I think the problem is that the while loop in the high acceptance of the VI page is too slow to read the data sent by the FPGA. I can see clealy waveform when the input frequency is low, but when the frequency is high the ugly looks of waveform. Is there a way I can see the waveform clealy high frequency in real time? Or I can use somethig like a FIFO to store data and view it later?

    Thank you

    Tong

    Hi Jeff,

    Thank you for your answer and I've already found the solution by myself.

    I did the FPGA and host screws by myself according to the example of "Getting started". I use the internal clock of 80 MHz in the FPGA VI. I'm trying to use NI 5732 to acquire the signal with a frequency of several MHz, so I think that the acquisition rate is fast enough.

    I solved the problem by using a target-to-host FIFO. The maximum size of the FIFO seemed to be 32767, so I put this value. Also, host VI, I put the number of items to be read from the FIFO to 10000. So I can view the MHz signal at the host VI.

    Best,

    Tong

  • Event processing and QuitUserInterface

    Dear experts,

    I have a very basic question

    I have a button leave with a callback routine associated that looks like:

    If (event is EVENT_COMMIT)
    {
    free dynamic memory

    close open files

    QuitUserInterface (0);

    }

    Now, it turns out that if a user is looking forward, he can hit the button leave twice and, of course, the callback routine is called twice, too, which causes an accident because the dynamics of memory has been released already in the first call. I would have assumed that after QuitUserInterface, no other event is handled... but it seems that pending events are still processed. Is this right?

    My solution to the problem would be to use a toggle setting to ensure that the callback is called once. But I wanted to (better) understand the treatment in the case of the event.

    Thank you!

    Hello Wolfgang,.

    I normally returns the order of operations to close the app: QuitUserInterface first of all, all the other tasks in the main function after RunUserInterface line. It also avoids events triggered, because the application is not over their treatment.

  • Difficulties to view events generated by the SSM-GOAL-10 on server CETS

    Hello

    Is there a trick that can help me to see the xml file generated by the CETS-server in a more convenient way. See attachment for more details.

    The events are interwoven with html tags.

    Thank you

    Julie

    Julie-

    If you don't want to read XML, you then have a script that it will look into something that is readable.

    I would suggest installing the free IPS Manager Express and pulling on the events of the probe, you want to see in it.

    Then, you can browse events in IME or export them to HTML or CSV format.

    Each sensor can send traffic events for up to 5 collectors event (even if it will cost you some processing on the sensor power to maintain additional sessions).

  • View event data

    Hello

    I would like to know what is the maximum time that we can record events in the event database. I remember the last time I was in view admin console, you couldn't assign the eventdb Records events for more than a month. Please correct me if iam wrong as I can not remember and do not have access to the console.

    I have read the integration guide and could find the answer.

    Also want to know if its possible to no vmware tools to record events in vmware view or tools with similar capabilities.

    Thank you.

    Well it is really just dumping in SQL.  If you know someone with good skills in SQL, so you could easily get what you are looking for.

  • View Events Database

    I'm trying to configure the db events and I get the message 'Database configuration error'.  View our environment is small enough, so I not create an installation full of SQL.  We will have less than 200 users, I think that for some time, so I used SQL Express.

    I created the db called ViewEvents and created a user called sql view with db_owner for the ViewEvents db rights.

    In the view Admin console I enter the info but get the error in config.   See attachment.viewerror.JPG

    I followed this guide and it works:

  • How to listen for the click to the button actionContent in view event

    Hello

    In doing so:

    FlexGlobals.topLevelApplication.addEventListener ('actionContentClick', showOptions);

    By calling showOptions() any time that the view had come out. Sticks of Manager and every time I get a view in the creationComplete for this turn I add the listener even over and over.

    How should this be done?

    1 FlexGlobals.topLevelApplication is the subject of the right to listen to?

    2. I can remove the listener on view turn off, but I don't know if that will be called whenever the view goes.

    3. check if an object already has an earpiece and who is he?

    Thank you.

    1 not sure; What exactly are you trying to do?

    2. Yes, every time you move to a separate view that will be dispatched to the VIEW_DEACTIVATE event. It would be a good place to remove the event listener.

    3. you can use hasEventListener(type:String) to test the presence of an event handler.
