Destroy and unsubscribing to events

If Cancel you the registration of an event before you destroy it or destroy everything first? Or is it important?

When the event is no longer required, it is recommended to cancel the registration of events. If you do not cancel the event recording that LabVIEW continues to generate and events queued until the VI runs even if no structure of the event is waiting to deal with. Of course, this will consume memory and would lead to other problems based on the application term.

I think that if your application wants to save events to only use that some point unregister for destroy events otherwise call user events after opt-out for sounds of events as a result of its use.

  • Can I detect and handle an event already within a structure of the event?

    I have a VI that would do what I want, if I could detect and handle an event of second mouse click while I'm already handling a previous event (selection from popup menu).

    I hope that the picture is clear, but in words what I want is the following: I have first right-click on a chart and select a context menu item, which specifies a graphic manipulation of properties.  Often, this manipulation requires clicking on a second graph to get a reference (for example if I want to copy some of the properties of the first chart on the chart of the target).  It is, it means I'm trying to detect a second event already within a structure of the event.

    I think I could do with a state machine and some registers at offset, and if it's the easiest way, I'll do it.  I would be interested to know whether, if there is a way to detect and manage events 'nested' as I suggested.

    Thank you!

    Your code is not really that complicated.

    Yet, the problem is that confuse you it upward with the main state machine. I would use it in a small parallel loop that only manages events associated with the menu shortcuts. All this should be able to run in parallel in any event, even if the main loop updates the data in the chart at the same time, for example.

    I don't like the dialog box, it hampers the flow of work, but if you use it, use two button dialog so that the user can also cancel if necessary. Instead of the dialog box, you should just temporarily move the cursor on. I also do little to check before operating on the second graph of reason and give a time limit for the second operation.

    Here is a quick project to a more atomic shortcuts Manager. Modify if needed. There are probably bugs.

  • Intercept the email opening and closing Email event.

    Hi all
    I created an app that does something, for example showing an alert when an email is opened or when enamel is closed. I am able to show the alert when I receive a call or hang up (via PhoneListener), but the problem is that I am not able to catch open the mail and close the event. I have no idea how this is possible. Please tell me if any APIs exist for this or any other means, it can be done.

  • Creating ent via API and post processing event handlers

    I have a number of post-processing-event handlers defined for the creation of the organization. They all work fine and do what they need to do when I create an organization via the web interface. However if I create an organization that uses the Java API, managers of events do not run. They are not supposed to run? I think that IOM should handle all the same applications - everywhere where they are generated.

    Here is my example of API:

    Import Thor.API.Exceptions.tcAPlException;
    Import Thor.API.Operations.tcOrganizationOperationslntf;
    import java.util.Hashtable;
    import java.util.HashMap;
    Import javax.security.auth.login.LoginException;
    Import oracle.iam. platform. OIMClient;

    public class test {}
    Public Shared Sub main (string [] args)
    {
    Hashtable env = new HashtableQ;
    approx. put (0IMc1 I ent. jAvA_NAMING_FACTORY_INITIAL, "weblogic.jndi.WLInitiialContextFactory");
    env.put (mpta OIMC]. JAVA_NAMING_PROVIDER_URL, "t3: / / localhost:14000");
    OIMClient oimclient = new olMClient (env);
    try {}
    oimclient. Login ("xelsysadm", args [O] .tocharArrayO); II the password is the only argument
    } catch (System.Exception e)
    System.out.println ("ERROR: connection exception.") Please check your username / password are correct. ») ;
    }
    tcorganizationOperationsintf orgManager = (tcOrganizationOperationsintf.class) oimclient.getservice;
    < String, String > HashMap hmorgDetails = new HashMap < String, String > ();
    hmOrgDetails.put ('Organizations.organizationName', 'org test');
    hmorgDetails.put ('Organizations.Type', 'Branch')
    Try
    {
    orgManager.createOrganization (hmorgDetails);
    } catch (Exception e) {}
    System.out.println (e. getMessage())
    e.printStackTraceQ;
    }
    return;
    }
    }

    and my definition of post processing:
    <? XML version = 'l.O' encoding = "uTF - 8"? >
    < eventhandlers xmlns = "http://www.oracle.com/schema/oim/platform/kernel."
    xmlns: xsi = "http://www.w3.org/2001/xMLschema-instance".
    xsi: schemaLocation = "http://www.oracle.com/schema/oim/platform/kernel%2dorchestrat-jon."
    -hand] ers. XSD">
    <! - custom preprocess event handlers - >
    < entity-type of the action handler = operation 'Organization' = 'CRΘER. '
    Class =' ' corn.corp.AutoCreateRoles
    name = 'Run in creating org'
    Stadium = "post-processing".
    order = "2000".
    Sync = "TRUE" / >

    Try to use OrganizationManager service class in your java code instead of the tcOrganizationOperationsIntf inheritance. Which should trigger the event handler. Recently, I had a problem where using the EntityManager on user has not triggered the eventhandler but only when using the UserManager triggered it.
    It would be possible only when you are using the legacy API, a new orchestration is not produced, and therefore the event handler is not called.

  • reversal, and then click event with swapping of images

    Dear people,

    I am looking for a simple way to solve my problem. I want to have a passage of the mouse and - effect on my bar of navigation, as well as on the click event, it should stay in the mouseover state. So far the mouseout/mouseouthandler() and the click event affect eachother on a wrong track. The example that I have attached here is done with plain rectangles, but later, they will be the images. So I guess that changes in css does not help me.

    I tried to understand some old threads here in the community, but they have reached a level of coding that isn't mine so far.

    MyStatusQuo: http://intern.ixtract.de/_3MFkJRIOOfbNZR

    I hope for your help and thanks in advance!

    It's very easy

    Just put your codes click between If like your mouseover and mouseout/mouseouthandler()

    sample for press 1 > click on

    If (WB! = 1) {}

    Buttons.Reset ();

    sym.getSymbol("btn1").$("back").css ({"background-color": "#ffbb0f"})

    Company is paid twice a month. The 15th and the last day of the month.

    If the 15th falls on the weekend, it will be Friday before the weekend. For example, May 15, 2016 falls on a Sunday, the event must be moved to May 13 instead. Is this possible?

  • IPhoto crashed and remove partial events

    I'm sorry, there was a similar thread, and I accidentally it marked as closed. He came from nowhere and I includes a summary and a link at the bottom.

    I launched iphoto 9.5.1 on 10.9.5 and have no good backup.  (Please do not pass judgment, I know I should have upgraded and saved...). Is it possible for me to return my events, changes, titles and other metadata?

    2 days ago iphoto crashed and would not restart. When you hold option + command while from iphoto did not (much less quick to rebuild) library, I installed iPhoto Library Manager who found the library without even an error message but only a fraction of the pictures (about 1500 to 6000). Photos seem to lack of each event, the films have been truncated. The most recent event was absent.

    I checked in the file system, Library.photolibrary/Masters/2014/05/10/ Pictures/iPhoto... the pictures were there and seem to be grouped reasonably, probably by import. A recovery of Library Manager iPhoto later with pictures of recovery orphan to return a batch of photos, I guess that all that were in events over what was in the trash. (Even after the removal of duplicates, I more than before.) They are in folders of every day now, I almost 500 instead of 90 and lost titles and most of the changes.

    With the help of iPhoto Library Manager to rebuild your iPhoto library

    1 - Download iPhoto Library Manager and launch. > click on the button Add library.

    2 - Select the library you want to add those in the selection window.

    3 - Make sure that the window box "photos orphan Scavange" is checked in the reconstruction.

    4. now that the library is listed in the left pane of PILM, click your library and go to the Library ➙ rebuild library menu option

    5. in the next window name the new library, and then select the location you want to be placed. Click on the button create.

    , Note 1: This creates a library based on the LIbraryData.xml file in the library and will retrieve the events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost.
