  • NSManagedObjectContext returns YES for hasChanges when there are none

    - by JK
    I created a separate NSManagedObjectContext on a separate thread to perform some store maintenance. However, I have noticed that the context returns YES for hasChanges as soon as a managed object in it is even referenced e.g. NSString *name = managedObject.name; This context is created and used exclusively in 1 method. Why is it returning has changes, when there there are none?

  • How to tell svn to not manage history for one file

    - by Prabu
    I don't know whether SVN has this feature, How do I tell svn to not maintain the history of changes for a file but it should have only the latest version of the file. Of course this is not the work of a version control, but it will be useful if I want to have some binary files within the repo without versioning.

  • Validation and Firefox's input caching

    - by Chris Simpson
    When you refresh/reload a page or use the back button, Firefox is kind enough to repopulate your inputs with what was entered before you navigated away. Though this is a nice feature it does not trigger my jquery validation and the unsaved changes warning I add to my pages. Is there a way to either disable this feature in Firefox (without renaming every control every time) or capture the firefox events?

  • Possible to "next track" e.g. Spotify from my app?

    - by parse
    I'm planning on doing a application for Android 2.1 that changes song every minute (through what I hope exists in Android, "next track") for the application using the audio device atm. So if I have Spotify (http://www.spotify.com) running in background already, playing music, can I through my program change to the next track? Let me know if I was unclear about anything. Thanks in advance!

  • waiting for 2 different events in a single thread

    - by João Portela
    component A (in C++) - is blocked waiting for alarm signals (not relevant) and IO signals (1 udp socket). has one handler for each of these. component B (java) - has to receive the same information the component A udp socket receives. periodicaly gives instructions that should be sent through component A udp socket. How to join both components? it is strongly desirable that: the changes to attach component B to component A are minimal (its not my code and it is not very pleasent to mess with). the time taken by the new operations (usually communicating with component B) interfere very little with the usual processing time of component A - this means that if the operations are going to take a "some" time I would rather use a thread or something to do them. note: since component A receives udp packets more frequently that it has component B instructions to forward, if necessary, it can only forward the instructions (when available) from the IO handler. my initial ideia was to develop a component C (in C++) that would sit inside the component A code (is this called an adapter?) that when instanciated starts the java process and makes the necessary connections (that not so little overhead in the initialization is not a problem). It would have 2 stacks, one for the data to give component B (lets call it Bstack) and for the data to give component A (lets call it Astack). It would sit on its thread (lets call it new-thread) waiting for data to be available in Bstack to send it over udp, and listen on the udp socket to put data on the Astack. This means that the changes to component A are only: when it receives a new UDP packet put it on the Bstack, and if there is something on the Astack sent it over its UDP socket (I decided for this because this socket would only be used in the main thread). One of the problems is that I don't know how to wait for both of these events at the same time using only one thread. so my questions are: Do I really need to use the main thread to send the data over component A socket or can I do it from the new-thread? (I think the answer is no, but I'm not sure about race conditions on sockets) how to I wait for both events? boost::condition_variable or something similar seems the solution in the case of the stack and boost::asio::io_service io_service.run() seems like the thing to use for the socket. Is there any other alternative solution for this problem that I'm not aware of? Thanks for reading this long text but I really wanted you to understand the problem.

  • OnDataBinding firing before OnLoad of a CustomGridViewControl in a UserControl?

    - by OutOFTouch
    Hi, I have a CustomGridViewControl that is on a UserControl, the UserControl is loaded outside of the Page_Init when a treeview in the page is clicked that changes the view, than on subsequent postbacks the UserControl is loaded in Page_Init. The custom gridview is bound to a dataview that is dynamically retrieved. Problem is that the OnDataBinding of the CustomGridView is firing before the OnLoad of the CustomGridView, which is causing me to not be able to get embedded resource urls. Any suggestions? Thanks!

  • diffing two databases

    - by flybywire
    Is there a tool to find the difference between two databases. Both the schema and the actual data are pretty much the same, but not 100%. Do you know a tool that can help to succinctly describe the changes.

  • How to build many projects with the same svn revision number with hudson?

    - by tangens
    I'm just starting with hudson and I'd like to build my projects like my handmade solution did before: Retrieve the current svn revision number rev. Build all projects (each with individual result) with the revision number rev. Start again with step 1 regardless if there were any changes in the meantime (to detect nondeterministic errors that don't occur on every test run). How can I configure this with hudson?

  • Inotifywait doesn't run command

    - by Marius Miliunas
    I have a basic inotifywait script called watch.sh and a few files ending in .styl in the same directory.

  • Get name given by phone number on the iPhone

    - by ganti
    I'm using a TextField where the user types a phone number. When the TextField changes, it should check if this number is already in the phonebook and display the name. So far, my only way is to parse all names and number in a Dict and read it from there. Is there a simpler, more efficient and sophisticated way to do that?

  • Can anyone help with this Magento error?

    - by Duane
    Fatal error: Call to a member function getArea() on a non-object in {directory}/includes/src/Mage_Core_Model_App_Area.php on line 155 Cropped up when I installed an extension that I wrote on a clean install of Magento. When ported to the dev server it took it down and I cant seem to find where it has originated. Disabling the extension changes nothing. Along with clearing the cache and all the regular Magento hiccups. I've ensured that file permissions are correct to the best of my knowledge.

  • Kernel error causing cpu to go into shutdown state

    - by EpsilonVector
    What kind of Kernel error can cause the cpu to go into a shut down state? I'm doing a homework assignment in OS, and we did changes in sched.c (adding a new scheduling policy, which involved ading another prio_array to the queue and switching between them when needed). Processes using this policy cause the cpu to enter a shut down state when they finish. Any suggestions where to look?

  • Dynamic title like in the Notes app

    - by Fran
    Hi, when the user enters text in a uitextview I would that the title of the navigation bar changed dynamically like it happens in the Notes app. How can I achieve this? I think a label is used, don't I? Thanks Fran EDIT: I know how change the title of a navigation bar, but how do this in a such way that the textview is tied to the title, so while user enters the first line of text in the same moment the title changes (letter by letter)?
