• 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.

• passing parameters to a thread

  - by assassin

  I want to pass a function that takes a parameter to the ThreadStart Constructor in C#. But, it seems that this is not possible, as I get a syntax error it I try to do something like this Thread t1 = new Thread(new Thread Start(func1(obj1)); where obj1 is an object of type List<string> (say). If I want a thread to execute this function that takes in an object as a parameter, and I plan to create 2 such threads simultaneously with different parameter values what is the best method to achieve this?

• Call AppDelegate Method from Class

  - by golfromeo

  Basically, I need to call a method in my AppDelegate from one of my view controller classes. Currently, I'm doing the following: myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate doMethod]; And including the myAppDelegate.h at the top of the .m file of the class: #import "myAppDelegate.h" When I run it, everything works... But I get the following warning: warning 'myAppDelegate' may not respond to '-doMethod' Is there another way that I should reference the app delegate? Thanks for any help in advance.

• Android: Custom Clock widget Service work-around?

  - by Anthony Forloney

  I was interested in developing a clock widget for the homescreen and upon reading Home Screen Widgets tutorial, is there a pre-existing Service I could reference for updating the current time rather than re-inventing the wheel? I have currently Retro Clock on my android phone and noticed that when I click it, it pops up the Alarm Clock settings, but with the default Google Analog Clock widget, upon click does nothing. Is that because the Retro Clock widget implements the Alarm Clock service? If so, how can I go about referencing that service? Or do I have this all wrong and misunderstood? Any help is appreciated. EDIT: I believe implementing the service to update the clock would drain the battery life tremendously, any ideas on a work around or help shed some light on any performance issues with using Service?

• Fitting maximum amount of shapes on a surface

  - by Fuu

  In industry, there is often a problem where you need to calculate the most efficient use of material, be it fabric, wood, metal etc. So the starting point is X amount of shapes of given dimensions, made out of polygons and/or curved lines, and target is another polygon of given dimensions. I assume many of the current CAM suites implement this, but having no experience using them or of their internals, what kind of computational algorithm is used to find the most efficient use of space? Can someone point me to a book or other reference that discusses this subject?

• Get nul value from one ViewController to one ViewController

  - by sovannarith

  I have 2 ViewControllers namely V1 and V2. I want to pass value from V2 to V1 but I get value 0 for countV1 in V1. I saw more questions in stackoverflow but I can't deal with this small problem. I use ARC.

• 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

• Passing a variable to javascript via a link.

  - by Jon

  My website has a javascript variable (addselectedsubdivision) that loads a neighborhood name from a box on the left to a box on the right. I was hoping I could build a link and then us PHP to add the subdivision letter, neighborhood, and city so that when you click on the link it goes right to this page and loads the neighborhood name in the box on the right. However, I can't get the variable to pass to the new page. Any suggestions? Website: http://www.mlsfinder.com/va_rein/jonmcachran/index.cfm?primarySearchType=sold&searchType=subdivision&so=a&domain=www.jonsellsvb.com&subdivision_string=p Example link: <a href="http://www.mlsfinder.com/va_rein/jonmcachran/index.cfm?primarySearchType=sold&searchType=subdivision&so=a&domain=www.jonsellsvb.com&subdivision_string=$firstletter" onLoad="addselectedsubdivision($neighborhood||$city);" target="_blank">

• python unit testing os.remove fails file system

  - by hwjp

  Am doing a bit of unit testing on a function which attempts to open a new file, but should fail if the file already exists. when the function runs sucessfully, the new file is created, so i want to delete it after every test run, but it doesn't seem to be working: class MyObject_Initialisation(unittest.TestCase): def setUp(self): if os.path.exists(TEMPORARY_FILE_NAME): try: os.remove(TEMPORARY_FILE_NAME) except WindowsError: #TODO: can't figure out how to fix this... #time.sleep(3) #self.setUp() #this just loops forever pass def tearDown(self): self.setUp() any thoughts? The Windows Error thrown seems to suggest the file is in use... could it be that the tests are run in parallel threads? I've read elsewhere that it's 'bad practice' to use the filesystem in unit testing, but really? Surely there's a way around this that doesn't invole dummying the filesystem?

• what the java command's -jar option really does

  - by JBoy

  Does the -jar option of the java command also compile the sources before running the main method? I believe so but i would like to have a better understanding of the internal process, from the man page you can clearly see a small workflow sequence: -jar Execute a program encapsulated in a JAR file. The first argument is the name of a JAR file instead of a startup class name. In order for this option to work, the manifest of the JAR file must contain a line of the form Main-Class: classname. Here, classname identifies the class having the public static void main(String[] args) method that serves as your application's starting point. See the Jar tool reference page and the Jar trail of the Java Tutorial @ But it does not mention that it compiles the sources.

• In which controller do you put the CRUD for the child part of a relationship?

  - by uriDium

  I am using ASP.Net MVC but this probably applies to all MVC patterns in general. My problem, for example I have companies and in each company I have a list of contacts. When I have selected a company I can see its details and a list of the contacts for that company. When I want to add a new contact for that company, should the implementation of that action go into the company controller as an "AddContact" action or should it go into the contact controller into a "New" action and we pass the Company ID in the URL? What is the usual way of dealing with this sort of thing in ASP.Net MVC? Is there a better stategy?

• How can I set the Rails environment for my somewhat stand alone Ruby script?

  - by Nick

  I have a Ruby script in my Rails app that I use to load some data from Twitter. In the future I will make it an automatic background process, but for now I run it manually like: ruby /lib/twitter/twitterLoad.rb In order to use the Rails model classes and such, I have the following as the top line of the script: require "#{File.dirname(__FILE__)}/../../config/environment.rb" By default, the development environment is used. But, I'd like to be able to choose the production environment at some point. Update #1: The RAILS_ENV constant is getting set in the environment.rb file. So, I was able to put ENV['RAILS_ENV'] = 'production' at the very top (before the environment.rb) line and solve my problem somewhat. So, my new question is, can do pass in env vars through the command line?

• Why wasn't C# designed with 'const' for variables and methods?

  - by spoulson

  I suspect const was simplified for the C# spec for general language simplicity. Was there a specific reason we can't declare variable references or methods as const like we can with C++? e.g.: const MyObject o = new MyObject(); // Want const cast referenece of MyObject o.SomeMethod(); // Theoretically legal because SomeMethod is const o.ChangeStuff(); // Theoretically illegal because ChangeStuff is not const class MyObject { public int val = 0; public void SomeMethod() const { // Do stuff, but can't mutate due to const declaration. } public void ChangeStuff() { // Code mutates this instance. Can't call with const reference. val++; } }

• Split text files Accross threads

  - by Kevin

  The problem: I have a few text files (10) with numbers in them on every line. I need to have them split across some threads I create using the pthread library. these threads that are created (worker threads) are to find the largest prime number that gets sent to them (and over all the largest prime from all of the text files). My current thoughts on solutions: I am thinking myself to have two arrays and all of the text files in one array and the other array will contain a binary file that I can read say 1000 lines and send the pointer to the index of that binary file in a struct that contains the id, file pointer, and file position and let it crank through that. a little bit of what I am talking about pthread_create(&threads[index],NULL,calc_sqrt,(void *)threadFields[index]);//Pass struct to each worker Struct: typedef struct threadFields{ int *id, *position; FILE *Fin; }tField; If anyone has any insight or a better solution it would be greatly appreciated Thanks

• Is it possible to use instanceof when passing objects between Threads?

  - by Risser

  I've run into an issue where instanceof works, and then it doesn't. Going into details is difficult, but I think this might be the problem: Reading this: http://www.theserverside.com/news/thread.tss?thread_id=40229 (search for Thread.currentThread), it seems to imply that, even if the two objects are the same class, if you pass them between threads with different class loaders, instanceof (and isAssignableFrom) might still fail. This certainly would explain the behavior I'm having, but I was wondering if anyone could verify it? (I wish the article linked at the beginning of the discussion was still available, but it doesn't seem like it is.) Thanks, Peter

• Buffering db inserts in multithreaded program

  - by Winter

  I have a system which breaks a large taks into small tasks using about 30 threads as a time. As each individual thread finishes it persists its calculated results to the database. What I want to achieve is to have each thread pass its results to a new persisance class that will perform a type of double buffering and data persistance while running in its own thread. For example, after 100 threads have moved their data to the buffer the persistance class then the persistance class swaps the buffers and persists all 100 entries to the database. This would allow utilization of prepared statements and thus cut way down on the I/O between the program and the database. Is there a pattern or good example of this type of multithreading double buffering?

• Receive messages for derived types in MVVMLight

  - by Hrvoje

  Shouldn't this test pass: [TestMethod] public void derived_message_subscription() { bool handled = false; Messenger.Default.Register<GenericMessage<baseClass>>(this, true, (msg) => handled = true); Messenger.Default.Send(new GenericMessage<testClass>(new testClass())); Assert.IsTrue(handled); } public abstract class baseClass { } public class testClass : baseClass { } I have to receive all messages for classes that inherits from one base class. MVVMLight has bool property receiveDerivedMessagesToo in Register method, but it seems to me that it isn't working.

• JavaScript's Associative Array / Object can't be read in functions

  - by Matrym

  At the very beginning of the javascript file, I have: var lbp = {}; lbp.defaults = { minLength: 40 }; I can successfully alert it afterwards, with: alert(lbp.defaults.minLength); But as soon as I put it inside a function, when I alert, I get "Undefined". What gives, and how do I avoid this? Is it absolutely necessary to pass this variable into each function, for example, by doing: function(lbp) { alert(lbp.defaults.minLength); } I would have thought that defining it first, it would attain global scope and not be required to be passed in? Thanks in advance for enlightening me :)

• 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?

• Multiple fields from LINQ to Text Box

  - by Chuki2

  how can I pass value from selected field (LINQ) to textbox in winforms? If single fields, I just do like this var result = from row in dtValueBranch.AsEnumerable() where row.Field<int>("branchID") == idBranch select row.Field<string>("branchName"); StringBuilder sb = new StringBuilder(); foreach (string s in result) { sb.Append(s + Environment.NewLine); } tbBranch.Text = sb.ToString(); So this is the code LINQ to many fields var result = from row in dtValueBranch.AsEnumerable() where row.Field<int>("branchID") == idBranch select new { BranchName = row["branchName"].ToString(), branchTel = row["branchTel1"].ToString(), // And many more fields }; How can I to implement each fields to each textbox?

• how does serializable work in java?

  - by Karl Trumstedt

  If I have an instance of a class that I store in a session I need to make it serializable. This class has a static variable, will this be serialized in every instance stored? The static variable is a reference to a cache containing a lot of data in the background. Will all of this data be serialized? If so, it seems preferable to make this variable transient and re-fetch the cache instance each time the instance is restored. Maybe not store the cache instance at all in the class. Will the constructor execute when a class is restored from a serialized state? if not is there any other method I can use to re-instate a transient variable?
