• Adding ivars to NSManagedObject subclass

  - by The Crazy Chimp

  When I create an entity using core data then generate a subclass of NSManagedObject from it I get the following output (in the .h): @class Foo; @interface Foo : NSManagedObject @property (nonatomic, retain) NSString *name; @property (nonatomic, retain) NSSet *otherValues; @end However, in my .m file I want to make use of the name and otherValues values. Normally I would simply create a couple of ivars and then add the properties for them as I required. That way I can access them in my .m file easily. In this situation would it be acceptable to do this? Would adding ivars to the .h (for name and otherValues) cause any unusual behaviour in the persistance & retrieval of objects?

• Why might RvdProxy.getServices() incorrectly return an empty Array?

  - by butterchicken

  The following code snippet attempts to create a Tib DaemonManager connecting to a particular rvd, and then query for that rvd's services. public static void main(String[] args) throws RuntimeException { DaemonManager daemonManager = new DaemonManager("http://foo.com:7580"); if(daemonManager.getDaemonType() == DaemonManager.RVD) { DaemonProxy daemonProxy = daemonManager.getDaemonProxy(); final RvdProxy rvdProxy = (RvdProxy) daemonProxy; Service[] services = rvdProxy.getServices(); System.out.println(services.length); //prints 0 for (Service service : services) { System.out.println(service.getNetwork()); } } } This prints zero, even though the web interface for this rvd lists multiple available services. Why might this happen? The daemon I am connecting to is running v 7.5.1 of the software, and the rvconfig.jar that I am using is from v 7.5.1 as well. Is there a gotcha when using Tibco's DaemonManager that is causing me to come unstuck?

• How to mock test a web service in PHPUnit across multiple tests?

  - by scraton

  I am attempting to test a web service interface class using PHPUnit. Basically, this class makes calls to a SoapClient object. I am attempting to test this class in PHPUnit using the "getMockFromWsdl" method described here: http://www.phpunit.de/manual/current/en/test-doubles.html#test-doubles.stubbing-and-mocking-web-services However, since I want to test multiple methods from this same class, every time I setup the object, I also have to setup the mock WSDL SoapClient object. This is causing a fatal error to be thrown: Fatal error: Cannot redeclare class xxxx in C:\web\php5\PEAR\PHPUnit\Framework\TestCase.php(1227) : eval()'d code on line 15 How can I use the same mock object across multiple tests without having to regenerate it off the WSDL each time? That seems to be the problem.

• Looking for a jQuery Developer [closed]

  - by Caroline Pires

  Hi, We are currently looking for a jquery developer, experienced specifically with flowplayer, to integrate a video player into our web application prototype. The player interface is being built in html and has to be wired to the flash player using the flowplayer jquery library. We also hope to be able to overlay some html elements on top of the video. A few extra jquery tools (scrollable and overlay) should be integrated with our page design as well. We are under a tight deadline and need to start work on this ASAP. For any further details please contact me on: [email protected] Thank you, Caroline

• Table View rotate, but not properly (shape change)

  - by Pencrace

  Hello everyone, Here is the thing. I have a ViewController which contain a view in full window. And the program run in landscape mode. I want to put an UITableView over the full screen view but only on right half part of the screen. So I add a UITableView in my view controller, I used the Interface Builder in order to set the Table View in the upper half of the screen so It will be on the right part in LandscapeLeft mode. I searched for on a lot of forum how to rotate my Table View. And so it does... except, It get stuck on the upper half of the landscape mode, it should stick on the right half. I'm not a iPhone coder since long, so I'm a bit confused on how to solve this problem. Do you have any idea on how to resize or make the TableView rotate properly. Thanks,

• WCF Service Memory Leaks

  - by Mubashar Ahmad

  Dear Devs I have a very small wcf service hosted in a console app. [ServiceContract] public interface IService1 { [OperationContract] void DoService(); } [ServiceBehavior(InstanceContextMode=InstanceContextMode.PerCall)] public class Service1 : IService1 { public void DoService() { } } and its being called as using (ServiceReference1.Service1Client client = new ServiceReference1.Service1Client()) { client.DoService(new DoServiceRequest()); client.Close(); } Please remember that service is published on basicHttpBindings. Problem Now when i performed above client code in a loop of 1000 i found big difference between "All Heap bytes" and "Private Bytes" performance counters (i used .net memory profiler). After investigation i found some of the objects are not properly disposed following are the list of those objects (1000 undisposed instance were found -- equals to the client calls) (namespace for all of them is System.ServiceModel.Channels) HttpOutput.ListenerResponseHttpOutput.ListenerResponseOutputStream BodyWriterMessage BufferedMessage HttpRequestContext.ListenerHttpContext.ListenerContextHttpInput.ListenerContextInputStream HttpRequestContext.ListenerHttpContext Questions Why do we have lot of undisposed objects and how to control them. Please Help

• Best way to handle input from a keyboard "wedge"

  - by Mykroft

  I'm writing a C# POS (point of sale) system that takes input from a keyboard wedge magcard reader. This means that any data it reads off of a mag stripe is entered as if it were typed on the keyboard very quickly. Currently I'm handling this by attaching to the KeyPress event and looking for a series of very fast key presses that contain the card swipe sentinel characters. Is there a better way to deal with this sort of input? Edit: The device does simply present the data as keystrokes and doesn't interface through some other driver. Also We use a wide range of these types of devices so ideally a method should work independent of the specific model of wedge being used. However if there is no other option I'll have to make do.

• Java dynamic proxy questions.

  - by Tony

  1.Does dynamic proxy instance subclass the target class? The java doc says the proxy instance implements "a list of interfaces", says nothing about subclassing, but through debugging, I saw that the proxy instance did inherit the target class properites.What does the "a list of interfaces " mean? Can I exclude those interfaces implemented by target class ? 2.Can I invoke target class specific methods on a proxy instance? 3. I think dynamic proxy is an interface methods invocation proxy but rather than a target class proxy, is that right (I am deeply infected by hibernate proxy object concept)?

• Initialize window code Mac OS X

  - by Jarle

  I'm currently reading "the red book" for learning OpenGL properly, and in one of the first examples, the author writes a line that says "InitializeAWindowPlease();" as a place holder for the code that will make a window to draw the OpenGL content in. Since I'm using Xcode for my programing, I know that I "get" a window to work with automatically (and that I have to make my own OpenGL view in interfacebuilder). How can I make this with pure code? I'm trying to learn programming, and I'm not to happy about taking "shortcuts" all the time. How can I make a window to draw my openGL stuff in? With Objective-C and C code I would love to see it. My goal is that I can make it without opening interface builder at all:)

• REST/ROA Architecture - Send database search/querying/filter/sorting parameters in URL? (>, <, IN, e

  - by DutrowLLC

  I'm building a REST interface to my application using ROA (Resource Oriented Architecture) . I'd like to give the client the ability to specify search parameters in URL. So a client could say "Give me all people who's: "first_name" is equal to "BOB" "age" is greater than "30" sort by "last_name" I was thinking something like: GET /PEOPLE/{query_parameters}/{sort_parameters} ...or perhaps GET /PEOPLE?query=<query_string>&sort=<sort_string> ...but I'm unsure what syntax would be good for specifying in the COLUMN_NAME-OPERATOR-VALUE triplicates. I was thinking perhaps something like: column_name.operator.value So the client could say: GET /PEOPLE?query=first_name.EQUALS.bob&query=age.GREATER_THAN.30&sort=last_name.ASCENDING I really don't want to re-invent the wheel here, are there some accepted ways that this is done? I am using Restlets, I don't know if that makes a difference.

• multiple occurences of HandleCreated for a single control

  - by Asher

  I’m using control that needs to be register to asynchronous events. The events will be raised in the UI thread using the ISynchronizeInvoke interface implemented by WinForms controls I can’t register to the event at the constructor because it will allow calling the event handler before the control is fully created. during which calls to ISynchronizeInvoke are not allowed. Solution to that problem is to use the perform the asynchronous event registration from an event handler to the HandleCreated instead of registering from the constructor. however, this poses another issue, in some scenations the HandleCreated event is raised multiple times as result of change at the control state. For example, each changing of the “RightToLeft” property causes a WMCreate message that cause raising the “HandleCreated” event. How can I prevent the multiply times of event rising? Is there is another way to know when the control is created and display for the first time? I can keep a boolean flag in the HandleCreated, however it feels like a hack and I am wondering if there is a better way to handle this issue.

• Objective-C: Protocols

  - by Stu

  I'd like an instance variable object to adopt a protocol. @interface GameScene : Scene <AVAudioPlayerDelegate> { @private Layer *content <CocosNodeOpacity>; } For example I'd like my Layer object to adopt the <CocosNodeOpacity> so that I can get the methods -(GLubyte) opacity; //and -(void) setOpacity: (GLubyte) opacity; for free. The syntax shown above is invalid. Is it possible to achieve this without creating a new implementation file and creating a custom object? Thanks.

• How can I easily make a java application invisible to the user?

  - by Pedro Bellora

  Hello! I have developed a Java aplication that is currently being run by double-clicking on a ".bat" file that does something like "java -jar proy.jar". This application just listens on a port and writes to a database, so it does not have any user interface (such as a window). I need this application to run as in background mode, or as it where a service, but I don't really anything more than that. It's enough if the application is run in a way that is not noticeable by the user, so that the user is not bothered and so the application can not be mistakenly closed. By the way, this will be run on an specific computer so it's okay if I have to do any manual configuration ir order to make this work. Also, I need this application to run on startup. Any help/tips regarding this? In advance, thank you very much for your help! Regards, Pedro

• Php PEAR, Database Abstraction & Factory Methods

  - by pws5068

  I'm interested in learning more about design practices in PHP for Database Abstraction & Factory methods. For background, my site is a special-interest social networking community currently in beta mode. Currently, I've started moving my old code for object retrieval to factory methods. However, I do feel like I'm limiting myself by keeping a lot of SQL table names and structure separated in each function/method. Questions: 1.) Is there a reason to use PEAR (or similar) if I dont anticipate switching databases? 2.) Can PEAR interface with the MySqli prepared statements I currently use? 3.) Will it help me separate table names from each method? (If no, what other design patterns might I want to research?) 4.) Will it slow down my site once I have a significantly large member base?

• In Elixir or SQLAlchemy, is there a way to also store a comment for a/each field in my entities?

  - by kchau

  Our project is basically a web interface to several systems of record. We have many tables mapped, and the names of each column aren't as well named and intuitive as we'd like... The users would like to know what data fields are available (i.e. what's been mapped from the database). But, it's pointless to just give them column names like: USER_REF1, USER_REF2, etc. So, I was wondering, is there a way to provide a comment in the declaration of my field? E.g. class SegregationCode(Entity): using_options(tablename="SEGREGATION_CODES") segCode = Field(String(20), colname="CODE", ... primary_key=True) #Have a comment attr too? If not, any suggestions?

• Using table-of-contents in code?

  - by AareP

  Do you use table-of-contents for listing all the functions (and maybe variables) of a class in the beginning of big source code file? I know that alternative to that kind of listing would be to split up big files into smaller classes/files, so that their class declaration would be self-explanatory enough.. but some complex tasks require a lot of code. I'm not sure is it really worth it spending your time subdividing implementation into multiple of files? Or is it ok to create an index-listing additionally to the class/interface declaration?

• In django models, how to make all table names not have the app label?

  - by Luigi

  I have a database that was already being used by other applications before i began writing a web interface with django for it. The table names follow simple naming standards, so the django model Customer should map to the table "customer" in the db. At the same time I'm adding new tables/models. Since I find it cumbersome to use app_customer every time i have to write a query (django's ORM is definitely not enough for them) in the other applications and I don't want to rename the existing tables, what is the best way to make all models in my django app use tables without applabel_, besides adding a Meta class with db_table= to each model? Is there any reason why I shouldn't do this? I have only one web app that needs to access this db, everything else doesn't use django models.

• Git remove directory

  - by hrickards

  I've got a repository on GitHub (http://github.com/hrickards/PHP-Crypto) for a little project me and a couple of others are working on. My development environment is Aptana Studio, and I use the EGit plugin as Aptana is basically Eclipse underneath. Today the designer sent the HTML and CSS for the website with the images in a folder named img. Previously the images were in a folder called images. Thinking nothing of it and being too lazy to update the CSS and HTML, I simply kept the images in the img directory and commited to Git. However, the GitHub web interface shows both the img and images directories, with the images directory being empty. I've tried deleting the images directory with git rm -r images and git rm images, and even mkdir images; git add images; git rm -r images but whatever I try I get the same result: fatal: pathspec 'images' did not match any files. Has anyone got any advice on how to remove images, or am I misunderstanding Git or something?

• jQuery event.layerX/Y is not relative to the element that triggered the event, is that correct?

  - by michielvoo

  If I use for example a mousemove event handler on a div and check the layerX property of the event, it changes when my mouse enters a positioned element inside that div (like an image). According to the jQuery Event object documentation it should follow the W3C DOM Level 3 specifications. But there's no mention of the layerX/Y property for the MouseEvent interface, so I'm wondering what behavior is according to specification? To me it seems that you always want the layerX/Y to be relative to the layer that fires the event, if I wanted the layerX/Y of a nested element, I would check the event in a different phase (bubbling) or would attach my handler to that nested element. My question is (somewhat subjective): how should layerX/Y work?
