  • android app working on simulator but not on phone

    - by raqz
    i have this app that i developed and it works great on the simulator with no errors what so ever. but the moment i try to run the same on the phone for testing, the app crashes stating filenotfoundexception. it says the file /res/drawable/divider_horizontal.9.png is missing. but actually speaking, i have never referenced that file through my code. i believe its a system/os file that is unavailable. i have a custom list view, i guess its the divider there... could somebody please suggest what is wrong here. i believe this is a similar issue discussed here..but i am unable to make any sense out of it http://code.google.com/p/transdroid/issues/detail?id=14 the listview.xml layout file <?xml version="1.0" encoding="utf-8"?> <LinearLayout

  • How to create mobile substrate plugins on XCode?

    - by prathumca
    Hi Everyone, I just wanna create a MS plugin to hook SpringBoard. I'm following "gojohnnyboi" tutorial from here "http://www.ipodtouchfans.com/forums/showthread.php?t=103558". To create a dylib on XCode, I'm following "SkylarEC" tutorial. I mix these two great tutorials and finally got succeed by getting a dylib. But when I placed the dylib in the /Library/MobileSubstrate/DynamicLibraries/ nothing is happened (no alert was shown). By evaluating, I found that, this dylib doesn't have any starting point when it was loaded into the memory. So I mentioned a starting point by declaring a constructor in the .mm file like, __ attribute__((constructor)) static void init() { Class _$SBAppIcon = objc_getClass("SBApplicationIcon"); MSHookMessage($SBAppIcon, @selector(launch), (IMP) &_$ExampleHook_AppIcon_Launch, "_OriginalMethodPrefix"); } But when I'm trying to compile this, I'm getting an error like, Undefined symbols: "_MSHookMessage", referenced from: init() in ExampleHook.o ld: symbol(s) not found collect2: ld returned 1 exit status. Does anyone has idea how to solve this? It would be great and more helpful if anyone share the detailed tutorial/instructions to create a dylib on XCode. P.S I placed all the libsubstrate.dylib and substrate.h files in the corresponding location. And the locations are, libsubstrate.dylib : /Developer/Platforms/iPhoneOS.platform/Developer/usr/lib/ substrate.h : /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/include and my base SDK is 3.0.

Does anyone know the possible reason? Thank you.

  • codeigniter and OOP general question regarding calling functions, and the parent constuctor

    - by thrice801
    Ok so I have some gaps in my understanding of PHP OOP, classes and functions specifically, this whole constructor class deal. I use both Zend and CI but right now Im trying to figure this out in CI as it is less complicated. So all Im trying to do is understand how to call a function from a view page in code igniter. I understand that might go against MVC but Im working with an api and search results not from my database, so basically, I want to define a function in my class that I am able to call in one of my view pages.. and I keep getting "Fatal error: Call to undefined function functionname" error no matter what I try. I thought I just had to declare public function testing() { echo "testing testing 123; } but calling that from the view I get that error. Then I read something about having to go parent::Controller(); in the index of the class where the testing function also resides? But that didnt work either. Anyways, ya, can someone explain what I need to do in order to call the "testing()" function on one of my view pages? and clarification on the constructor class and what exactly parent::Controller() even does, would be much appreciated as well.

I have tried to create a GUI in which allows the user to specify these config parameters and then click submit. When the user clicks submit a new GameInitializer object is created. The error I am getting is: Exception in thread "AWT-EventQueue-0" java.lang.Error: Cannot call invokeAndWait from the event dispatcher thread at java.awt.EventQueue.invokeAndWait(Unknown Source) at javax.swing.SwingUtilities.invokeAndWait(Unknown Source) at game.player.humanplayer.view.HumanView.update(HumanView.java:43) once submit is called this code is executed: values assigned to parames... new GameInitializer(userName, player, Constants.BLIND_STRUCTURE_FILES.get(blindStructure), handState); Then code in the GameInitializer constructor is: public GameInitializer(String playerName, AbstractPlayer opponent, String blindStructureConfig, AbstractHandState handState){ beginGame(playerName, opponent, blindStructureConfig, handState); } public static void beginGame(String playerName, AbstractPlayer opponent, String blindStructureConfig, AbstractHandState handState){ AbstractDealer dealer; BlindStructure.initialize(blindStructureConfig); AbstractPlayer humanPlayer = new HumanPlayer(playerName, handState); AbstractPlayer[] players = new AbstractPlayer[2]; players[0] = humanPlayer; players[1] = opponent; handState.setTableLayout(players); for(AbstractPlayer player : players){ player.initialize(); } dealer = new Dealer(players, handState); dealer.beginGame(); } It basically cascades down and eventually calls this piece of code in the HumanView class: public void update(final Event event, final ReadableHandState handState, final AbstractPlayer player) { try { SwingUtilities.invokeAndWait(new Runnable() { public void run() { gamePanel.update(event, handState, player); validate(); } }); } catch (InterruptedException e) { e.printStackTrace(); } catch (InvocationTargetException e) { e.printStackTrace(); } if(event.equals(Event.HAND_ENDING)){ try { if(handState.wonByShowdown() || handState.isSplitPot()){ Thread.sleep(3500); } else{ Thread.sleep(1000); } } catch (InterruptedException e) { e.printStackTrace(); } } } Do you have any idea why?

  • Error when instantiating .NET/COM interop class via classic ASP

    - by Lee D
    Hi all, I am having a problem when trying to instantiate a C# .NET class that's been exposed to COM in a classic ASP application. I've used tlbexp to generate a typelib and registered it in Component Services; now when trying to create the object as such: Server.CreateObject("The.Class.Name") I am getting the error: Server object error 'ASP 0177 : 80131534' Server.CreateObject Failed I've searched around online for information on this error, and found numerous discussions but no solution. The error code 0x80131534 apparently means "COR_E_TYPEINITIALIZATION, a type failed to initialize", which would suggest the problem would be in the constructor. The constructor of the class in question sets a private field to an instance of another class from the same assembly, and then reads some configuration settings from an XML file. This behaviour is unit tested and I've checked that the file exists; I can't see anything else that could be breaking in there. A few other points which may or may not be of use: A test .NET project referencing the DLL can instantiate the class just fine; however a test VB6 project referencing the TLB blows up with the same error. Both the DLL and the TLB are in the same location. This application is running locally, on Windows XP Professional SP3 and IIS 5.1. The .NET assembly is built with .NET Framework 2.0, although 3.5 is installed on the machine. I know other people who don't get this error on their builds, so I believe it may be something environmental. Any suggestions are welcome as I've been struggling to fix this for some time. Thanks in advance.

  • Delphi - Message loop for Form created in DirectShow filter goes dead

    - by Robert Oschler
    I have a DirectShow filter created with Delphi Pro 6 and the DSPACK direct show library. I'm running under windows XP. I've tried creating the form dynamically when the container class for the DirectFilter has its constructor called, passing NIL into the constructor as the AOwner parameter (TMyForm.Create(nil) and then calling the Form's Show() method. The form does show but then appears to stop receiving windows messages because it never repaints and does not respond to input. As a test I then tried creating my own WndProc() and overriding the Form's WndProc(). My WndProc() did get called once but never again. I'm guessing it's because I'm a DLL and the context that I am running in is not "friendly" to the window message handler for the form; perhaps something to do with the thread that calls it or whatever. If someone could give me a tip on how to solve this or what the proper way to create a persistent window is from the context of a DirectShow filter I'd appreciate it. Note, as I said the window needs to be persistent so I can't create it as a Filter property page. Thanks, Robert

  • How to avoid using this in a contructor

    - by Paralife
    I have this situation: interface MessageListener { void onMessageReceipt(Message message); } class MessageReceiver { MessageListener listener; public MessageReceiver(MessageListener listener, other arguments...) { this.listener = listener; } loop() { Message message = nextMessage(); listener.onMessageReceipt(message); } } and I want to avoid the following pattern: (Using the this in the Client constructor) class Client implements MessageListener { MessageReceiver receiver; MessageSender sender; public Client(...) { receiver = new MessageReceiver(this, other arguments...); sender = new Sender(...); } . . . @Override public void onMessageReceipt(Message message) { if(Message.isGood()) sender.send("Congrtulations"); else sender.send("Boooooooo"); } } The reason why i need the above functionality is because i want to call the sender inside the onMessageReceipt() function, for example to send a reply. But I dont want to pass the sender into a listener, so the only way I can think of is containing the sender in a class that implements the listener, hence the above resulting Client implementation. Is there a way to achive this without the use of 'this' in the constructor? It feels bizare and i dont like it, since i am passing myself to an object(MessageReceiver) before I am fully constructed. On the other hand, the MessageReceiver is not passed from outside, it is constructed inside, but does this 'purifies' the bizarre pattern? I am seeking for an alternative or an assurance of some kind that this is safe, or situations on which it might backfire on me.

  • XAML Binding to complex value objects

    - by Gus
    I have a complex value object class that has 1) a number or read-only properties; 2) a private constructor; and 3) a number of static singleton instance properties [so the properties of a ComplexValueObject never change and an individual value is instantiated once in the application's lifecycle]. public class ComplexValueClass { /* A number of read only properties */ private readonly string _propertyOne; public string PropertyOne { get { return _propertyOne; } } private readonly string _propertyTwo; public string PropertyTwo { get { return _propertyTwo; } } /* a private constructor */ private ComplexValueClass(string propertyOne, string propertyTwo) { _propertyOne = propertyOne; _propertyTwo = PropertyTwo; } /* a number of singleton instances */ private static ComplexValueClass _complexValueObjectOne; public static ComplexValueClass ComplexValueObjectOne { get { if (_complexValueObjectOne == null) { _complexValueObjectOne = new ComplexValueClass("string one", "string two"); } return _complexValueObjectOne; } } private static ComplexValueClass _complexValueObjectTwo; public static ComplexValueClass ComplexValueObjectTwo { get { if (_complexValueObjectTwo == null) { _complexValueObjectTwo = new ComplexValueClass("string three", "string four"); } return _complexValueObjectTwo; } } } I have a data context class that looks something like this: public class DataContextClass : INotifyPropertyChanged { private ComplexValueClass _complexValueClass; public ComplexValueClass ComplexValueObject { get { return _complexValueClass; } set { _complexValueClass = value; PropertyChanged(this, new PropertyChangedEventArgs("ComplexValueObject")); } } } I would like to write a XAML binding statement to a property on my complex value object that updates the UI whenever the entire complex value object changes. What is the best and/or most concise way of doing this? I have something like: <Object Value="{Binding ComplexValueObject.PropertyOne}" /> but the UI does not update when ComplexValueObject as a whole changes.

  • Getter and Setter - POJO object - Problem with input data in Struts2

    - by andreimladin
    I have a problem with setter and getter method in struts2. I have a form : ... + all input fields of job/ and action: (addJob is mapped at this action) public class InsertJobAction extends ActionSupport{ ... private Job job = null; public String execute(){ jobService.insert(job); //here job is not null; that is ok } getter and setter for job } this action works correctly; I have a similar form and action, but the input fields from thisform are less than first form; The problem is here: in execute() of the second action job is null. Why?? Does depend it of fields noumber ?? I have 2 constructors in my Job class one with no params, and one with all params for every field of class; I made debug with Log4j ...and in first case there arrives in Job constructor in the second not. Why??When it calls constructor??? When are called the setter and getter methodsb, before or after execute() method??? And when i have a form with input data?? Are called setter methods before execute() method? I'm very confusely because in a case it works without problems, but in the second case it doesn't Thanks, Andrew

  • Java: volatile guarantees and out-of-order execution

    - by WizardOfOdds
    Note that this question is solely about the volatile keyword and the volatile guarantees: it is not about the synchronized keyword (so please don't answer "you must use synchronize" for I don't have any issue to solve: I simply want to understand the volatile guarantees (or lack of guarantees) regarding out-of-order execution). Say we have an object containing two volatile String references that are initialized to null by the constructor and that we have only one way to modify the two String: by calling setBoth(...) and that we can only set their references afterwards to non-null reference (only the constructor is allowed to set them to null). For example (it's just an example, there's no question yet): public class SO { private volatile String a; private volatile String b; public SO() { a = null; b = null; } public void setBoth( @NotNull final String one, @NotNull final String two ) { a = one; b = two; } public String getA() { return a; } public String getB() { return b; } } In setBoth(...), the line assigning the non-null parameter "a" appears before the line assigning the non-null parameter "b". Then if I do this (once again, there's no question, the question is coming next): if ( so.getB() != null ) { System.out.println( so.getA().length ); } Am I correct in my understanding that due to out-of-order execution I can get a NullPointerException? In other words: there's no guarantee that because I read a non-null "b" I'll read a non-null "a"? Because due to out-of-order (multi)processor and the way volatile works "b" could be assigned before "a"? volatile guarantees that reads subsequent to a write shall always see the last written value, but here there's an out-of-order "issue" right? (once again, the "issue" is made on purpose to try to understand the semantics of the volatile keyword and the Java Memory Model, not to solve a problem).

  • CodeIgniter's Scaffolding and Helper Functions Not Working

    - by 01010011
    Hi, I'm following CodeIgniter's tutorial "Create a blog in 20 minutes" and I am having trouble getting the helper, anchor and Scaffolding functions to work. I can't seem to create links on my HTML page using the helper and anchor functions. I put $this->load->helper('url'); $this->load->helper('form'); in the constructor under parent::Controller(); and <p>&lt;?php anchor('blog/comments','Comments'); ?&gt;</p> within the foreach loop as specified in the tutorial. But Im not getting the links to appear. Secondly, I keep getting a 404 Page Not Found error whenever I try to access CodeIgniter's Scaffolding page in my browser, like so: localhost/codeignitor/index.php/blog/scaffolding/mysecretword I can access localhost/codeignitor/index.php/blog just fine. I followed CodeIgnitor's instructions in their "Create a blog in 20 minutes" by storing my database settings in the database.php file; and automatically connecting to the database by inserting "database" in the core array of the autoload.php; and I've added both parent::Controller(); and $this->load->scaffolding('myTableName') to blog's constructor. It still gives me this 404. Any assistance will be appreciated. Thanks in advance?

  • How to get child container reference in View Model

    - by niels-verkaart
    Hello, I´m trying to share a Data Service (Entity Manager) wrapped in a Repository from a ViewModel (called 'AVM') in Module A to a ViewModel (called 'BVM') in Module B, and I can't get this working. We use PRISM/Unity 2.0 This is my scenario: A user may open multiple Customer screens (composite view as mini shell) each with another customer (unit of work). We realize this using child containers. Each child container resolves it's own repository with its own Entity manager (the repository is a singleton within the child container). This is done in module A. The main shell has a main region manager, and each Customer screen with its childcontainer creates a scoped region. In each customer screen there is a View 'AV' (connected to ViewModel 'AVM') with a SubRegion (tab control) registered as 'SubRegion'. We create this with a 'Screen Factory' In Module B we have a Customer Orders in View 'BV' and ViewModel 'BVM'. In the constructor of Module B we get the main container by injection. In the initialize method we resolve the (main) region manager and register View 'BV' with it. In the constructor of View 'BV' a ViewModel 'BVM' is injected/created. Now this works, but the ViewModel 'BVM' cannot get the child container. It only get the main container. Is this doable, or do I have to do this another way? Thanks, Niels

  • Generic allocator class without variadic templates?

    - by rainer
    I am trying to write a generic allocator class that does not really release an object's memory when it is free()'d but holds it in a queue and returns a previously allocated object if a new one is requested. Now, what I can't wrap my head around is how to pass arguments to the object's constructor when using my allocator (at least without resorting to variadic templates, that is). The alloc() function i came up with looks like this: template <typename... T> inline T *alloc(const &T... args) { T *p; if (_free.empty()) { p = new T(args...); } else { p = _free.front(); _free.pop(); // to call the ctor of T, we need to first call its DTor p->~T(); p = new( p ) T(args...); } return p; } Still, I need the code to be compatible with today's C++ (and older versions of GCC that do not support variadic templates). Is there any other way to go about passing an arbitrary amount of arguments to the objects constructor?

  • ASP.NET MVC Using Castle Windsor IoC

    - by Mad Halfling
    I have an app, modelled on the one from Apress Pro ASP.NET MVC that uses castle windsor's IoC to instantiate the controllers with their respective repositories, and this is working fine e.g. public class ItemController : Controller { private IItemsRepository itemsRepository; public ItemController(IItemsRepository windsorItemsRepository) { this.itemsRepository = windsorItemsRepository; } with using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using Castle.Windsor; using Castle.Windsor.Configuration.Interpreters; using Castle.Core.Resource; using System.Reflection; using Castle.Core; namespace WebUI { public class WindsorControllerFactory : DefaultControllerFactory { WindsorContainer container; // The constructor: // 1. Sets up a new IoC container // 2. Registers all components specified in web.config // 3. Registers all controller types as components public WindsorControllerFactory() { // Instantiate a container, taking configuration from web.config container = new WindsorContainer(new XmlInterpreter(new ConfigResource("castle"))); // Also register all the controller types as transient var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes() where typeof(IController).IsAssignableFrom(t) select t; foreach (Type t in controllerTypes) container.AddComponentWithLifestyle(t.FullName, t, LifestyleType.Transient); } // Constructs the controller instance needed to service each request protected override IController GetControllerInstance(Type controllerType) { return (IController)container.Resolve(controllerType); } } } controlling the controller creation. I sometimes need to create other repository instances within controllers, to pick up data from other places, can I do this using the CW IoC, if so then how? I have been playing around with the creation of new controller classes, as they should auto-register with my existing code (if I can get this working, I can register them properly later) but when I try to instantiate them there is an obvious objection as I can't supply a repos class for the constructor (I was pretty sure that was the wrong way to go about it anyway). Any help (especially examples) would be much appreciated. Cheers MH

  • Why isn't my new object being seen? C#

    - by Dan
    I am getting ready to take a class at a college on C#. I have been reading up on it a lot and decided to start a fun project. Here is what my project consists of: Main Control Form Configuration Form Arduino Program.cs calls Configuration.cs at start. This is where pin modes for the Arduino are set and where a timer is set. When I set these values, they get sent to MainControl.cs. When I hit the "Save" button in Configuration.cs, a MainControl.cs object is created [[I am correct in that?]] All of those values that were sent by Configuration.cs had corresponding setters that set private static variables in MainControl.cs [[ I don't really know if that is the preferred way, I am most definetly open to any suggestion anyone has]] MainControl.cs uses its default constructor, and this constructor calls a method that creates an arduino object from one of the private variables (serialPort) [[ Using this Arduino class Firmata.NET ]] When the arduino object is created, I know (I guess I do) because the form takes a few seconds to come up (As opposed to not using serial port) My problem is this: I do not understand why nothing can see the object I have been very wordy, I apologize if I wasn't concise. Here is the code: public partial class CMainControl : Form { private static string serialPort; public CMainControl() { InitializeComponent(); createArduino(); updateConfig(); // Change label values to values set in configuration } private void createArduino() { Arduino arduino = new Arduino(serialPort); } In Configuration.cs, when I set the serial port through a combobox, the value is sent to MainControl.cs just fine. Here is the error I get: Error 1 The name 'arduino' does not exist in the current context C:\Programming\Visual Studio\Workhead Demo\Workhead Demo\CMainControl.cs 94 13 Workhead Demo Please let me know if anyone can help and/or offer pointers, and please let me know if I didn't post or format anything correctly. Thank you very much :)

  • GWT CssResource Customization

    - by Eric Landry
    I'm writing a GWT widget using UIBinder and MVP. The widget's default styles are defined in TheWidgetView.ui.xml: <ui:style type="com.widgetlib.spinner.display.TheWidgetView.MyStyle"> .textbox { border: 1px solid #red; } .important { font-weight: bold; } </ui:style> The widget's CssResource interface is defined in TheWidgetView.java: public class TheWidgetView extends HorizontalPanel implements TheWidgetPresenter.Display { // ... some code @UiField MyStyle style; public interface MyStyle extends CssResource { String textbox(); String important(); } // ... more code } I'd like the consumer of this widget to be able to customize part of the widget's styles and to have this in their MyExample.ui.xml: <ui:style type="com.consumer.MyExample.MyStyle"> .textbox { border: 2px solid #black; } </ui:style> And this be their MyExample.java: public class MyExample extends Composite { // ... some code @UiField MyStyle style; interface MyStyle extends TheWidgetView.MyStyle{ String textbox(); } // ... more code } Is there a way that my widget can have default styles, but that the consumer of the widget can override one of them? When an interface extends TheWidgetView.MyStyle, the of the widget consumer needs to define all the styles listed in that parent interface. I've seen some widget libraries have the widget's constructor take in a ClientBundle as parameter, which I suppose could apply to CssResource. Although, I'm not sure how I'd pass in this style object in a constructor invoked by UIBinder. Thanks much in advance!

  • Configure WebLogic MDB to listen to Foreing AMQ Server

    - by eliel.lobo
    I'm trying to create an MDB(EJB 3.0) on WebLogic 10.3.5. to listen to a Queue in an external AMQ server. but after much work and combination of tutorials i get the followin error when deployin on WwebLogic. [EJB:015027]The Message-Driven EJB is transactional but JMS connection factory referenced by the JNDI name: ActiveMQXAConnectionFactory is not a JMS XA connection factory. Here is a brief of the work i have done: I have added the corresponding libraries to my WLS classpath (following thos tuturial http://amadei.com.br/blog/index.php/connecting-weblogic-and-activemq) and I have created the corresponding JMS Modules as indicated in the tutorial. As connection factory I have used ActiveMQConnectionFactory initially and ActiveMQXAConnectionFactory later, I also ignome the jms. notation an just put plain names as testQueue. Then create a simple MDB whit the following structure. I explicitly defined "connectionFactoryJndiName" property because otherwise it assumes a WebLogic connection factory which is not found an then raises an error. @MessageDriven( activationConfig = { @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"), @ActivationConfigProperty(propertyName = "destination", propertyValue = "testQueue"), @ActivationConfigProperty(propertyName = "connectionFactoryJndiName", propertyValue = "ActiveMQXAConnectionFactory") }, mappedName = "testQueue") public class ROMELReceiver implements MessageListener { /** * Default constructor. */ public ROMELReceiver() { // TODO Auto-generated constructor stub } /** * @see MessageListener#onMessage(Message) */ public void onMessage(Message message) { System.out.println("Message received"); } } At this point I'm stuck with the error mentioned above. Even though I use ActiveMQXAConnectionFactory instead of simply ActiveMQConnectionFactory, JNDI resources tree in web logic server shows org.apache.activemq.ActiveMQConnectionFactory as class for my configured connection factory. am i missing something? or is this just a completely wrong way to connect WebLogic whith AMQ? Thanks in advance.

  • Is this correct for disposing an object using IDisposable

    - by robUK
    I have a class that implements the IDisposable interface. I am using a webclient to download some data using the AsyncDownloadString. I am wondering have I correctly declared my event handlers in the constructor and within the using statement of the web client? And is this correct way to remove the event handlers in the Dispose method? Overrule is this the correct way to use the IDisposable interface? public class Balance : IDisposable { //Constructor WebClient wc; public Balance() { using (wc = new WebClient()) { //Create event handler for the progress changed and download completed events wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged); wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); } } ~Balance() { this.Dispose(false); } //Get the current balance for the user that is logged in. //If the balance returned from the server is NULL display error to the user. //Null could occur if the DB has been stopped or the server is down. public void GetBalance(string sipUsername) { //Remove the underscore ( _ ) from the username, as this is not needed to get the balance. sipUsername = sipUsername.Remove(0, 1); string strURL = string.Format("https://www.xxxxxxx.com", sipUsername); //Download only when the webclient is not busy. if (!wc.IsBusy) { // Download the current balance. wc.DownloadStringAsync(new Uri(strURL)); } else { Console.Write("Busy please try again"); } } //return and display the balance after the download has fully completed void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { //Pass the result to the event handler } //Dispose of the balance object public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } //Remove the event handlers private bool isDisposed = false; private void Dispose(bool disposing) { if (!this.isDisposed) { if (disposing) { wc.DownloadProgressChanged -= new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged); wc.DownloadStringCompleted -= new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); wc.Dispose(); } isDisposed = true; } } }

  • How to use boost::bind with non-copyable params, for example boost::promise ?

    - by zhengxi
    Some C++ objects have no copy constructor, but have move constructor. For example, boost::promise. How can I bind those objects using their move constructors ? #include <boost/thread.hpp> void fullfil_1(boost::promise<int>& prom, int x) { prom.set_value(x); } boost::function<void()> get_functor() { // boost::promise is not copyable, but movable boost::promise<int> pi; // compilation error boost::function<void()> f_set_one = boost::bind(&fullfil_1, pi, 1); // compilation error as well boost::function<void()> f_set_one = boost::bind(&fullfil_1, std::move(pi), 1); // PS. I know, it is possible to bind a pointer to the object instead of // the object itself. But it is weird solution, in this case I will have // to take cake about lifetime of the object instead of delegating that to // boost::bind (by moving object into boost::function object) // // weird: pi will be destroyed on leaving the scope boost::function<void()> f_set_one = boost::bind(&fullfil_1, boost::ref(pi), 1); return f_set_one; }
