  • MPMediaickerController memory leak identified by Leaks instrument

    - by Joe
    This is code from Apple's Addmusic example. MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic]; picker.delegate = self; picker.allowsPickingMultipleItems = YES; picker.prompt = NSLocalizedString (@"Add songs to play", "Prompt in media item picker"); // The media item picker uses the default UI style, so it needs a default-style // status bar to match it visually [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES]; [self presentModalViewController: picker animated: YES]; [picker release]; I'm using this code in my app and the Leaks instrument highlights a leak on the line: [self presentModalViewController: picker animated: YES]; I think that this is because this line retains a reference to picker which cannot be subsequently released. Is there any way around this or is Leaks incorrectly identifying a leak?

  • Why my WCF Service returns xml serialized objects?

    - by user294554
    Hi, I'm new here and I hope anyonte can help me. I have WCF Service and Windows Forms working with this client written in VB.NET. The Service class started to return xml serialized objects, but all my classes on Service side are DataContract-s and the service class is DataContractFormat. I googled everywhere about serializations and I couldn't find reason why it started to do that. I checked my classes and service, app.config file, but I couldn't find anything. I checked Reference.vb class, and it's System.Xml.Serialization.XmlElementAttribute everywhere. The question may seem dummy, but I really don't know what to do. I just want to know what can cause the service to act like that. Thank you.

  • What are the semantics of [myThing.myProperty release]?

    - by dugla
    I clearly have not fully grocked properties. I have an instance of a class, myThing. myThing has a property that has be synthesized: // .h @property(nonatomic,retain)MyCoolType *coolType; // .m @synthesize coolType; In my program I call: // The retain count on MyCoolType is 1. [myThing.coolType release]; The reference count on MyCoolType is now zero and dealloc should fire. So, shouldn't myThing.coolType now be nil? In my code that is not the case. How do a correctly release and force the property to return nil? Thanks, Doug

  • Microsoft MyPhone - .NET access possible?

    - by ZombieSheep
    I've searched this as much as I can in the time available, but haven't turned anything up. Does anyone know if it is possible to access data backed up from a WinMo device to Microsoft's MyPhone service programatically, without having to restore all the data back to the device? I'm looking at a way of also keeping a local backup of contacts and SMS messages on my desktop machine, but it seems that if there is an API for doing so, Microsoft haven't advertised it at all. I'm hoping that my inability to find any reference on Google is due to my incompetence rather than it not being supported by Microsoft.

  • Error when accessing IIS 7 server variable from ASP.Net MVC

    - by StephSpr
    I have an ASP.Net MVC application which works fine on IIS 6.0 / Windows Server 2003. When installed on IIS 7.5 / Windows Server 2008 (integrated mode), it works but when the application attempts to generate an URL, it runs into the following error: [NullReferenceException: Object reference not set to an instance of an object.] System.Web.HttpServerVarsCollection.Get(String name) +10960764 System.Web.Mvc.PathHelpers.GenerateClientUrlInternal(HttpContextBase httpContext, String contentPath) +345 System.Web.Mvc.PathHelpers.GenerateClientUrl(HttpContextBase httpContext, String contentPath) +80 System.Web.Mvc.UrlHelper.GenerateUrl(String routeName, String actionName, String controllerName, RouteValueDictionary routeValues, RouteCollection routeCollection, RequestContext requestContext, Boolean includeImplicitMvcValues) +256 System.Web.Mvc.UrlHelper.Action(String actionName, String controllerName, RouteValueDictionary routeValues) +36 It looks like IIS7 fails to return the server name. There should be a configuration to set, but I couldn't find anything like that. Do you have any idea to fix this issue ? Thanks,

  • How can I fix "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the conte

    - by slolife
    I have a user control (ascx) that I have added two public properties to: RequestTypeId and GroupId. Both have the attribute set. In my aspx page, I have a ListView, and in the ItemTemplate, I place my control reference, like so: <ctrl:ServiceTypeGroup runat="server" RequestTypeId="<%#RequestType.RequestTypeId%>" GroupId='<%#Eval("Id").ToString()%>' /> Setting the RequestTypeId works fine. Setting the GroupId fails with the following error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control." What do I need to do to my user control code to allow binding a Eval() expression to one of its properties? Or is it not possible?

  • Linq: comparison with nonexisting value should not cause the exception, but it does

    - by Seacat
    Hello, Given I don't know if the parameter will be null or not and I want to use it in the following way: if Param != null then compare with its id if Param == null then compare with null. Something like that: var c = from cat in context.Categories where ParamCat != null && cat.ParentId == ParamCat.Id || ParamCat == null && cat.ParentId == null select c; If ParamCat is null as soon as I try to get something from c (for example c.Count()) it throws the exception. Usually when we use some kind of condition it stop comparison as soon as condition fail especially if we use AND. For example this code will not cause any exception: if (ParamCat != null && cat.ParentId == RaramCat.Id) { } If so, why the linq code above throw exception? (Null reference) Thanks

  • How can I call an Actionscript function when the .swf is referenced by jQuery?

    - by Arms
    I have an .swf that I am embedding into HTML using the jQuery SWF Object plugin (http://jquery.thewikies.com/swfobject). I have a number of functions within the .swf that I need to call from within javascript functions. I've made these actionscript functions accessible to javascript by calling flash.external.ExternalInterface.addCallback(). Yet nothing happens when I make the call. I've had this happen before and it seems to be that when you reference the .swf from jQuery, you can't call flash functions. Is there anyway around this (aside from not using jQuery)? Thanks.

  • Foreign Key vs. Independent Relationships - is there improvement with Entity Framework 5?

    - by zam6ak
    I have read several articles and questions on concept of foreign key vs independent relationship when using Entity Framework. And I am still not 100% sure which way to go.... I would prefer not to "pollute" my domain POCOs by having a property that will be used in FK relationship when I already have a property reference to "has a" object. My questions are (looking at you @EFTeam, @Ladislav Mrnka) are there any improvements on this subject in the upcoming Entity Framework v5? are there more advantages if I use FK instead of independent associations (particularly with code first)?

  • Know if a Visual Studio Website project is recompiling itself in the background?

    - by jdk
    A number of team members update a central ASP.NET dev site (Website project, not a Web application type). Some kinds of changes cause a recompile/rebuild in it. The large website takes a while to recompile and we've noticed it will still seemingly serve out dynamic pages before everything is internally updated. During the site's "gestation" period, our mileage varies while hitting it. Sometimes we get a correct page, sometimes an compilation error page that will eventually be served up without a compilation error, and at other times an unexpected hybrid. Is it possible to query an ASP.NET website application to see if it's currently compiling or rebuilding itself? If so I would write a status page that the team could reference when they're getting weird behaviour, so they would know to wait. Update: Our team often edit files manually on the dev server. For production we'd make pre-compiled pushes. The dev environment is a little more malleable and ever-changing so I'm looking for a solution to reducing the "confusion" there.

  • TypeError: Error #1009 Actionscript 3 help.

    - by matt_t
    I am extremely frustrated. I'm following a tutorial and mimicing it on my own. I've been able to sort out most of the errors so far but this one has me stumped. I have tried replacing all of the class files with the tutorial specimen ones but i still get the error. TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.senocular.utils::KeyObject/construct() at com.senocular.utils::KeyObject() at com.asgamer.basics1::Ship() at com.asgamer.basics1::Engine() Now, not really understanding the error properly I paste dumped the files online for you to look at. Ship class: textbin.com/78z35 Engine class: textbin.com/32b24 KeyObject class: textbin.com/p2725 As the error still occured when using the specimen class files I really have no idea where to begin. I will gladly try out any suggestions (although later on, i'm tired now ;). Thanks very much.

  • VS 2010 Debugger: Any way to search an object for a particular value?

    - by Dr. Zim
    I am trying to search the "this" object in an ASP.NET MVC 2 for a string value. In a view, I set the partial view input tag prefix and am trying to figure out how to reference it in the partial view itself. For example: Html.EditorFor(m => m, "templateName", "fieldPrefix"); In the partial view, I would like to search the "this" object for my fieldPrefix string to see where the MVC folks decided to store it. Any ideas?

  • UIEvent timestamp

    - by skajam66
    When handling a UIButton touch, you are given a UIEvent object. The UIEvent object has a timestamp which the Apple documentation states as being "the time that the event was created" (UIEvent Class Reference). In the documentation on the Main Event Loop, it states that: "The application object obtains the topmost object in the event queue, converts it to an event object (UIEvent) ..." Does [UIEvent timestamp] refer to the time at which the UIEvent object is created (i.e. after processing the touch event off of the main run loop and hance not remotely real-time) or does it refer to the time that the underlying touch object was created (and hence as close as possible to representing the actual time of the user touch9?

  • Compiling C-dll for Python OR SWIG-module creation, how to continue ??

    - by ljuju
    I reference this file "kbdext.c" and its headerfile listed on http://www.docdroppers.org/wiki/index.php?title=Writing_Keyloggers (the listings are at the bottom). I've been trying to compile this into a dll for use in Python or Visual Basic, but have not succeeded. I'm not familiar with C or GCC to sort out the problems or do the dll compile correctly. (I also get an error about snprintf not being declared when doing a regular compile of all the files). What are the steps I should do to make all functions available for other languages and external apps? Or is it perhaps easier to use SWIG and make a python module, instead of compiling a DLL?

  • .rdlc reporting bound to Object Data Source in Three layer Application

    - by Saeedouv
    Hi, i have the following situation, i have a Reporting layer(stand alone) in asp.net application(NOT website, this means NO App_Code folder exists), and i want just to create Object Data Source to take an Object in a separate layer(lets say from Data Access Layer), and then to use that Object Data Source to create a report, i have spent my whole day working around that, tons of work around's and articles on the web, but does not mention what i really want to do, any answer is appriciated... just to make things more clear here, assume the following: i have a solution with the follwoing layers, UI Reporting(has NO Employees object) just a reference Business Logic Data Access Layer(Employees--GetEmployees(), all i need is as mentioned above, i want to create Object Data Source from Reporting layer, to take Employee object from DAL, and then use it's GetEmployees method to be added to report, i think its more clear now, since also Reporting layer has NO App_Code folder.

  • Castle Windsor Weak Typed Factory

    - by JeffN825
    In a very very limited number of scenarios, I need to go from an unknown Type (at compile time) to an instance of the object registered for that type. For the most part, I use typed factories and I know the type I want to resolve at compile time...so I inject a Func<IMyType> into a constructor ...but in these limited number of scenarios, in order to avoid a direct call to the container (and thus having to reference Windsor from the library, which is an anti-pattern I'd like to avoid), I need to inject a Func<Type,object>...which I want to internally container.Resolve(type) for the Type parameter of the Func. Does anyone have some suggestions on the easiest/most straightforward way of setting this up? I tried the following, but with this setup, I end up bypassing the regular TypedFactoryFacility altogether which is definitely not what I want: Kernel.Register(Component.For(typeof (Func<Type, object>)).LifeStyle.Singleton.UsingFactoryMethod( (kernel, componentModel, creationContext) => kernel.Resolve(/* not sure what to put here... */))); Thanks in advance for any assistance.

  • Annotations: methods vs variables

    - by Zenzen
    I was always sure (don't know why) that it's better to add annotations to variables, but while browsing the Hibernate doc http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-hibspec-collection I noticed they tend to annotate the methods. So should I put my annotations before methods, like this: @Entity public class Flight implements Serializable { private long id; @Id @GeneratedValue public long getId() { return id; } public void setId(long id) { this.id = id; } } Or is it better to do it like this: @Entity public class Flight implements Serializable { @Id @GeneratedValue private long id; public long getId() { return id; } public void setId(long id) { this.id = id; } } Or maybe there's no difference?

  • Issue with storing items in session in MVC

    - by Sundeep
    I have a customer page on which user can enter multiple locations for customer. I am using telerik ajax grid to display locations, and when a new location is added, I am adding it to session and returning back to the grid. Finally, when user submits, customer and all locations using customerid as reference key gets inserted. I am clearing the session, when user enters create/edit page and on successful commit or any exception occurs. Problem is when user adds the locations for one user and then opens another tab, to create another user then all locations get cleared for previous user. Coz of session, this issue is occuring. Something of viewstate would be page specific. But for ajax grid actions, viewdata/viewbag is not working. Any thoughts on how to implement this. Thanks in advance.

  • Handling JSON and HTML templates in jQuery

    - by Toby Hede
    I have an ajax-enabled site that presents a lot of dynamic content by interpolating JSON values with HTML. This all works fine. BUT it means I have significant amounts of HTML all through my JavaScript. For example: var template = "<div>Foo: {bar}</div><div>Blah: {vtha}</div>"; template.interpolate({bar:"bar",blah:"vtha"}); I have cut this down a fair bit - some of my dynamic elements have quite a lot of HTML and a lot going on. I am using jQuery and I am building on Rails, so if there is something smart in either framework, that would be great. For reference, the String interpolation function used above is: String.prototype.interpolate = function (o) { return this.replace(/{([^{}]*)}/g, function (a, b) { var r = o[b]; return typeof r === 'string' || typeof r === 'number' ? r : a; } ); };

  • rails - caches_action expire_action

    Hi I want to expire a cached action and wondered how to generate the correct reference. #controller caches_action :index, :layout => false #generates this fragment which works fine views/0.0.0.0:3000/article/someid/posts #sweeper ... expire_action article_posts_path(:article_id => post.article) # results in this Expired fragment: views//en/article/someid/posts (0.0ms) So this is almost ok, except the host is missing. What do I do that supplies this to the expire_action method? Thanks in advance.

  • PHP - white screen of death!

    - by Industrial
    Hi everyone, After debugging a codeigniter app that were installed into a new development environment, I have started to freak out when seeing white screens with nothing more available. I have been able to solve each and every one of the errors that have caused this, but it have taken seriously way too long time. PHP error_reporting(E_ALL) & display_errors", 1 is set as well. I even installed Xdebug in hope of getting more output, but no. My logging settings are also working, but nothing is written to the log. Is there a way to get something informative printed out instead of a complete white screen? It would certainly shorten my time spent on solving the eventual errors that causes this? Thanks a lot!

  • A depth (z-index) nightmare.

    - by JCOC611
    The best way to illustrate this question is with...a Fiddle! Before you visit the fiddle, notice there is text behind the grayest element, which is on top of a light gray element that has a border. There is a main wrapping div (root), and two wrapping divs inside (wrap1 and wrap2). The problem here is that I need the content of wrap2 (highlight) to be behind the content of wrap1 (text), but in front of the background of the root. This, however, must not change: The HTML, the elements and wraps should be left untouched. Excluding the order of wrap1 and wrap2 inside root. The highlight div must keep the absolute positioning. Styling highlight with background-color is not an option, the existence of highlight is a must. PS: the italics reference the id's of <div>s in the fiddle example, for whomever was too lazy to visit it.

  • Subprocess with variables & Command from different class

    - by Pastelinux
    source: http://pastebin.com/utL7Ebeq My thinking is that if i run from controller class "main" it will allow me to take the "data" from Class "model", def "filename". It doesn't seem to work. As you can see below what i mean class Controller: def __init__(self): self.model = Model() self.view = View() def main(self): data = self.model.filename() self.view.tcpdump(data) class View: def tcpdump(self, command): subprocess.call(command.split(), shell=False) When i run my code i get this error: subprocess.call(command.split(), shell=False) AttributeError: 'NoneType' object has no attribute 'split' My guess means that its not picking up command (look at source for reference) or that its not getting command with variables. But i know the error when variables are not being picked up so i don't think it is that. My question is, from what i have thus far, how do i from "class view" grab "command" for my subprocesses to run. Thanks~ John Riselvato
