How to cancel NSInvocationOperation in a queue?

Hi
I'm loading images into a scrollview, which loads in a NSInvocationOperation. But I want when I scroll the view to cancel the current operation:
I used this method, but it doesn't cancel the operation. In the documentation stands that I must use the isCancelled Property but I don't understand it how to use it
- (void)scrollViewWillBeginDecelerating:(UIScrollView *)scrollView {
[threadQueue cancelAllOperations];
Please help..
Thanks

No one an answer?

  • How to cancel all alert email in WF_NOTIFICATIONS_OUT Queue.

    Hi,
    Could any body show how to cancel all the alert email present in WF_NOTIFICATIONS_OUT queue.
    We are running 12.0.4. i have seen Doc. id. 433359.1 Tracking Workflow Notification Event Messages.
    According to this before i can recreate the queue i need to process the alert emails.
    I do not want these alert emails to be processed since it is a clone instance. I want it to either go to a test email account or to be discarded
    completely.
    I know how to send it to test email account by using setoverrde address functionality in OAM. But for that to be set i need to start the mailer (which is currently down), if i start, it will start firing these pending alert emails in WF_NOTIFICATIONS_OUT.
    Kindly suggest.

    Hi,
    These documents talk about purgin WF_NOTIFICATIONS_OUT queue. But document i mentioned
    says.
    7. Try rebuilding the WF_NOTIFICATION_OUT queue if necessary
    The wfntfqup.sql script rebuilds the WF_NOTIFICATION_OUT queue by dropping and recreating
    that queue, removing pending notification messages from the WF_DEFERRED queue, and
    repopulating the WF_NOTIFICATION_OUT queue from the Oracle Workflow Notification System
    tables.
    Wfntfqup.sql Version >=115.9
    If you have implemented Oracle Alert and the WFNOTIFICATION_OUT queue contains any pending_
    alert e-mail messages, those messages must be processed before the queue can be rebuilt. The
    wfntfqup.sql script checks the queue for any alert e-mail messages and, if it finds any, the
    script returns an error message that specifies how many alert e-mail messages are pending
    and indicates that these messages must be processed before the script can run.
    Kindly suggest.

  • How to cancel a print job in progress

    I have a HP C5580.  When i was using Windows ME on my former PC, I could easily go to Printers, select the 5580,  hit documents in queue, and hit cancel , and the printer stopped.
    Got a new Compaq  PC with Windows 7, and I can't figure out how to cancel a print job  mid stream.  I go to Printers and Devices, giet the page that allows me to view the print jobs in queue, I hit "print job in process", but the "Cancel" is not in bold print and I can'tfind any other way to cancel the job.
    Help !

    The easiest way to cancel a print job would be by pressing the cancle button on the front panel.  This is the "X" button near the right side of the control panel, see pages 10 and 11 of the user manual here.

  • How do you clear the download queue?

    I've reached the 3,333 track limit on my device (Android phone) and keep getting the message every time I go switch off offline mode, because I have tracks queued to download but obviously can't.How can I clear the download queue, to stop the message (and download different tracks after I undownload some others)?

    I've ran into that buying a movie. You cannot cancel it. It has to finish downloading then delete it. I tried emailing apple, they told me to do it that way. I also heard they can clear your queue(apple), but that didn't happen to me. Sorry, I looked everywhere as well. I would buy a movie on my iPad to watch on atv and I had to do it that way. I just purchase from tv now and download later on MacBook or iPad if I want it.

    Recommended way for binding the list event handler to the list instance is through feature receivers.
    You need to create a feature file like the below sample
    <?xmlversion="1.0"encoding="utf-8"?>
    <Feature xmlns="http://schemas.microsoft.com/sharepoint/"
    Id="{20FF80BB-83D9-41bc-8FFA-E589067AF783}"
    Title="Installs MyFeatureReceiver"
    Description="Installs MyFeatureReceiver" Hidden="False" Version="1.0.0.0" Scope="Site"
    ReceiverClass="ClassLibrary1.MyFeatureReceiver"
    ReceiverAssembly="ClassLibrary1, Version=1.0.0.0, Culture=neutral,
    PublicKeyToken=6c5894e55cb0f391">
    </Feature>For registering/binding the list event handler to the list instance, use the below sample codeusing System;
    using Microsoft.SharePoint;
    namespace ClassLibrary1
        public class MyFeatureReceiver: SPFeatureReceiver
            public override void FeatureActivated(SPFeatureReceiverProperties properties)
                SPSite siteCollection = properties.Feature.Parent as SPSite;
                SPWeb site = siteCollection.AllWebs["Docs"];
                SPList list = site.Lists["MyList"];
                SPEventReceiverDefinition rd = list.EventReceivers.Add();
                rd.Name = "My Event Receiver";
                rd.Class = "ClassLibrary1.MyListEventReceiver1";
                rd.Assembly = "ClassLibrary1, Version=1.0.0.0, Culture=neutral,
                    PublicKeyToken=6c5894e55cb0f391";
                rd.Data = "My Event Receiver data";
                rd.Type = SPEventReceiverType.FieldAdding;
                rd.Update();
            public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
                SPSite sitecollection = properties.Feature.Parent as SPSite;
                SPWeb site = sitecollection.AllWebs["Docs"];
                SPList list = site.Lists["MyList"];
                foreach (SPEventReceiverDefinition rd in list.EventReceivers)
                    if (rd.Name == "My Event Receiver")
                        rd.Delete();
            public override void FeatureInstalled(SPFeatureReceiverProperties properties)
            public override void FeatureUninstalling(SPFeatureReceiverProperties properties)
    }Reference link: http://msdn.microsoft.com/en-us/library/ff713710(v=office.12).aspxOther ways of registering the list event handlers to the List instance are through code, stsadm commands and content types.

    Regards
    sapman man

    Hi
    Cancelling of excise invoice will be done in the following ways depending on the situation.
    Case 1:
    Create PO
    Do MIGO (create and post excise invoice)
    Create return delivery in quality inspection.
    Now we have to create a rejection inmvoice in J1IS with reference to the return delivery wherein the excise values gets reversed.
    If u try to reverse part 2 entries in J1IEX it will not come.
    Case2:
    Create PO
    Do MIGO (create and post excise invoice)
    Do cancellation of MIGO (102 mvt)
    With ref to vendor or internal excise invoice number just post the transaction. excise part 2 entries will get reversed. This will happen only if 102 entry exist for the PO line item.
    In a nutshell excise entries cancellation comes only if we cancel the material document. If we do return delivery then we have to create rejection excise invoice.
    Hope u get cleared in this regards
    Reg

    Brian,
    Again, not accurate. When Match is "turned off" all of the Matched song instances are still shown in the Ibrary and all devices still stream - so, if you have your songs also stored on your local drive (which I choose to as one does not always have access to WiFi and I use the local instances of the songs for some music production/DJing), iTunes shows each song twice.  This is cumbersome if you simply want to play an album - you have to hear each song twice. There is no reason technologically they could not simply show the metadata for a song only once and simply hit the cloud object store when it it is not found as a local disk target. This would solve some of the issues and it is pretty much how any content delivery network (CDN) works - and this is how my local Genius Bar assured me it would work before I bought the service. I found they know little about Match.
    Other issues: I believe the "exclusive" Cloud Playtlist logic still stands - iTunes protests if you add a non-Matched song to a Playlist (as it assumes you want all Playlists to be cloudy). Also, the APLCARE person and I  could not figure out what "Removed" (under Cloud Status) means despite looking up several explanations on the Web. And, we found songs that were only in the cloud that should have also been on my local drive as I never deleted them. That said, it is also a pain to fully delete a song (local + the cloud). Plus, the logic in the Purchased section around what constitutes "Not On Computer" did not hold up. They have lots of logical challenges with thier workflow.
    Regardingyour suggestion, there is no way to "not use" Match. Only when one is disconnected from the iTunes store does Match seem to go away completely.The only thing you can turn off is the song syncing/matching/uploading. This amounts only to turning off a sub-process not the service.
    Match is likely fine for most who do not want to have any copy of the songs locally and are fine having access to their music only when connected via WiFi. I wanted more ubiquitous access to my collection from my iPad and my iPhone but needed to keep my songs local to my MBP too. This is not the proper use case as I have learned.
    Of course I won't renew, but I should be able to cancel a service that I am dissatisfied with.
