  • JSONP not firing on IPad

    - by Gemtag
    After trying everything possible I've come to the conclusion this is an issue with IPad Safari. This works in FF, IE, Chrome, and Safari on MacBook. Below is my dumbed-down code. I have 2 separate JSONP calls, This first one works in all browsers including IPad. This simply calls a function based on a blur event $('#gender').blur(function() { reTarget(); }); function reTarget() { $.getJSON("http://host.com/Jsonpgm?jsoncallback=?", function() { } ); } Below is where things break. On the same page as the above code is the following, which calls a function based on a submit button click. $(':submit').bind('click', function(event) { if (checkThis() == false) { return false; }; }); $('form').bind('submit', function(event) { if (checkThis() == false) { return false; }; }); function checkThis() { $.getJSON("http://host.com/Jsonpgm.aspx?jsoncallback=?", function() { } ); } This code will not fire. I've put alerts right before it and they fire. I look at the web logs and there is no entry for this json call. I would take any suggestions on this. At this point I fear it's a problem with firing jsonp from a submit event.

  • How can I differentiate two different touches on a layer ?

    - by srikanth rongali
    I am writing an app in cocos2d. I hava a sprite and a text in my scene. I have written two separate classes for sprite and text. And I added both of them to another class. In sprite class I have written - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event And in text class I have written -(void) registerWithTouchDispatcher { [[CCTouchDispatcher sharedDispatcher]addTargetedDelegate:self priority:0 swallowsTouches:YES]; } -(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { return YES; } -(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event { NSLog(@"Recognized tOuches in Instructions");// CGSize windowSize = [[CCDirector sharedDirector] winSize]; CCNode *node = [self getChildByTag:kTagNode]; [node setPosition: ccp(text1.contentSize.width/2,text1.contentSize.height/2 - windowSize.height)]; } -(void) ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchLocation = [touch locationInView: [touch view]]; CGPoint prevLocation = [touch previousLocationInView: [touch view]]; touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation]; prevLocation = [[CCDirector sharedDirector] convertToGL: prevLocation]; CGPoint diff = ccpSub(touchLocation,prevLocation); CCNode *node = [self getChildByTag:kTagNode]; CGPoint currentPos = [node position]; [node setPosition: ccpAdd(currentPos, diff)]; } But, only touches in the text are recognized and touch of sprite is not recognized ? How can I differentiate the two touches.

  • ConcurrenctBag(Of MyType) Vs List(Of MyType)

    - by Ben
    What is the advantage of using a ConcurrentBag(Of MyType) against just using a List(Of MyType)? The MSDN page on the CB (http://msdn.microsoft.com/en-us/library/dd381779(v=VS.100).aspx) states that ConcurrentBag(Of T) is a thread-safe bag implementation, optimized for scenarios where the same thread will be both producing and consuming data stored in the bag So what is the advantage? I can understand the advantage of the other collection types in the Concurrency namespace, but this one puzzled me. Thanks.

  • What are some jQuery plugins that you've desired?

    - by meder
    While I'm pretty sure this might just get closed, I might just have some free time on my hands so I'm opening a request thread to see if anyone desires a jQuery plugin that I might be able to provide - if you have a specific request for a plugin that you can't find which isn't overly demanding ( such as a game ) can you reply to this thread?

  • EventKitUI view and edit problem!

    - by Alish
    I try to to find a solution to do View and Edit of a the item from a tablview. My application base on UITabBarController. Each of the Bar items contain a class with a a couple of UIViews. This is the first items of UITabBarController. I done Add event from Apple sample code: SimpleEKDemo. Add Event working without any problem. I tried to add View and Edit part to the code. I would able to select an items from tableView to edit the selected item. But after I tried to add code from SimpleEKDemo to my code, I realized I have to add UINavigationController to the implement. So I did. After I add that it's came to the items of UITabBarController. Also I even the Add Event didn't worked very well (I couldn't insert event name and location. but edit was working. So I need to know: 1- Is it possible to implement Edit/View without using UINavigationController. If yes please let me know a sample code. 2- If I must use UINavigationController. Because I don't need UINavigationController to become it the first page and I don't need any bar added to my application. Is it possible it's appear in the application when I choose a item of tableView but appear alike that! Snapshots: https://public.me.com/alish (pict.zip)

  • What is Apache process model?

    - by Morgan Cheng
    I have been googling this question for some time but got no answers. What's the Apache process model? By process model, I mean how Apache manage process or thread to handling HTTP request. Does it fork one process for each HTTP request? Does it have process/thread pool? Can we config it? Is there any online doc for such Apache details?

  • When calling a static method on parent class, can the parent class deduce the type on the child (C#)

    - by Matt
    Suppose we have 2 classes, Child, and the class from which it inherits, Parent. class Parent { public static void MyFunction(){} } class Child : Parent { } Is it possible to determine in the parent class how the method was called? Because we can call it two ways: Parent.MyFunction(); Child.MyFunction(); My current approach was trying to use: MethodInfo.GetCurrentMethod().ReflectedType; // and MethodInfo.GetCurrentMethod().DeclaringType; But both appear to return the Parent type. If you are wondering what, exactly I am trying to accomplish (and why I am violating the basic OOP rule that the parent shouldn't have to know anything about the child), the short of it is this (let me know if you want the long version): I have a Model structure representing some of our data that persists to the database. All of these models inherit from an abstract Parent. This parent implements a couple of events, such as SaveEvent, DeleteEvent, etc. We want to be able to subscribe to events specific to the type. So, even though the event is in the parent, I want to be able to do: Child.SaveEvent += new EventHandler((sender, args) => {}); I have everything in place, where the event is actually backed by a dictionary of event handlers, hashed by type. The last thing I need to get working is correctly detecting the Child type, when doing Child.SaveEvent. I know I can implement the event in each child class (even forcing it through use of abstract), but it would be nice to keep it all in the parent, which is the class actually firing the events (since it implements the common save/delete/change functionality).

  • How to delete Drawn Line in java?

    Hello Folks, well this is my code: import javax.swing.; import javax.; import java.awt.; import java.awt.Color; import java.awt.Graphics.; import java.awt.event.*; import javax.swing.UIManager; public class SimpleGUI extends JFrame{ public SimpleGUI(){ this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) ; } public void go(){ Drawpanel = new Mypanel(); JFrame frame = new JFrame("Chasing Line"); frame.getContentPane().add(BorderLayout.CENTER, Drawpanel); frame.setSize(300,300); frame.setVisible(true); Drawpanel.addMouseMotionListener(new java.awt.event.MouseMotionAdapter() { public void mouseMoved(java.awt.event.MouseEvent evt) { DrawpanelMouseMoved(evt); } }); } public void DrawpanelMouseMoved(java.awt.event.MouseEvent evt) { xpos=evt.getX(); ypos=evt.getY(); System.out.println("Coordinates : X :"+ xpos+"Y: "+ypos); Drawpanel.paintImage(xpos,ypos); } class Mypanel extends JPanel{ public void paintImage(int xpost,int ypost){ Graphics d = getGraphics(); d.setColor(Color.black); d.drawLine(xpost, 0, xpost, this.getHeight()); d.setColor(Color.red); d.drawLine(0, ypost, this.getWidth(),ypost); this.validate(); } } // end the inner class public static void main(String[] args){ try { UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel"); } catch(Exception e) { System.err.println("Look and feel not set"); } SimpleGUI win = new SimpleGUI(); win.go(); } Mypanel Drawpanel; private int xpos=0; private int ypos=0; } // close SimpleGUI class The problem is how can i delete the old lines?, i mea,make only the current x and y lines appear on the screen, make the intersection between both lines "follow" the mouse pointer. thanks for any reply.

  • Better alternative for PipedReader/PipedWriter?

    - by Esko Luontola
    I need to have a buffered char stream, into which I write in one thread and from which I read in another thread. Right now I'm using PipedReader and PipedWriter for it, but those classes cause a performance problem: PipedReader does a wait(1000) when its internal buffer is empty, which causes my application to lag visibly. Would there be some library which does the same thing as PipedReader/PipedWriter, but with better performance? Or will I have to implement my own wheels?

  • How expensive is synchronization?

    - by someguy
    I am writing a networking application using the java.nio api. My plan is to perform I/O on one thread, and handle events on another. To do this though, I need to synchronize reading/writing so that a race condition is never met. Bearing in mind that I need to handle thousands of connections concurrently, is synchronization worth it, or should I use a single thread for I/O and event handling?

  • SDL (And Others) Virtual Key Input

    - by David C
    Today I set up the input in my application for all the different keys. This works fine except for virtual keys, for example, caret or ampersand. Keys that normally need shift to be got at. Using SDL these virtual keys don't work. As in they do not register an event. if (event.type == SDL_KEYDOWN) { switch (event.key.keysym.sym) { case SDLK_CARET: Keys[KeyCodes::Caret] = KeyState::Down; break; case SDLK_UP: Keys[KeyCodes::Up] = KeyState::Down; break; default: break; } I am absolutely sure my system works with physical keys like Up. The program queries a keystate like so: if (Keys[KeyCode] == KeyState::Down) { lua_pushboolean(L, true); } else { lua_pushboolean(L, false); } KeyCode is passed in as an argument. So why are virtual keys, or keys that need shift to get at not working using SDL's KeyDown event type? Is more code needed to get to them? Or am I being stupid?

  • SerialPort.Write() - How to stop writing?

    - by DaniMelo
    Hello, I am developing in C# using the SerialPort class. SerialPort.Write() is a blocking method. How can I exit this method when I want to stop writing? I use a thread to write. I abort this thread when I want to stop writing but the COM port continues to write. Any ideas? Thanks a lot. Sorry for my basic English.

  • EventHandlers saved to databases.

    - by Stacey
    In a database application (using Sql Server right now, in C#, with Entity Framework 4.0) I have a situation where I need to trigger events when some values change. For instance assume a class "Trackable". class Trackable { string Name { get; set; } int Positive { get; set; } int Negative { get; set; } int Total { get; set; } // event OnChanged } Trackable is represented in the database as follows; table Trackables Id | guid name | varchar(32) positive | int negative | int Total is of course, calculated at runtime. When a trackable event changes, I want to inspect its previous value, and then see what it is changing to, and be capable of reacting accordingly. However different trackables need to trigger different events (to avoid a huge, massive cascading switch/if block). If this were just only C# code it would be easy - but they have to be saved to the database. I can't divide up each different trackable into a different table/class, that would be silly - they are all identical, but the event raised is different based on how they are made. So I guess my question is, is there any way to store an event handler in a database such that.. Trackable t1 = new Trackable() { Name = "Trackable1" OnChange += TrackableChangedEventHandler(OnTrackable1Change) } Trackable t2 = new Trackable() { Name = "Trackable2", OnChange += TrackableChangedEventHandler(OnTrackable2Change) }

  • What to do if one library is not multi-threaded ?

    - by LB
    Hi, I would like to multi-thread an application, however one library i'm using is not multi-thread capable (i don't know what's the right word ? synchronized ?). What are my options ? As far as i know there's nothing in between threads and processes (Runtime.exec) in java (no abstraction in the jvm to have something like an isolated "java process"). How would you deal with that ?

  • send socket c ctrl+c behavior

    - by out_sider
    I'm witting an application based on a server and various client but I'm having a problem with the send command. Whenever I do ctrl+c on the client side the send operation kills the thread which is in and the process running (in order to have multiple clients I set a thread to which one). If the client ends (doing the close socket) properly the server doesn't die, but when I use the ctrl+c combination on the client both exit. What can I do to prevent send commando to have this behavior? Thx in advance
