  • Will Apple's new "originally written in" clause affect your decision to target the iPhone?

    - by Michael Aaron Safyan
    So, you've probably heard about Apple's change to its agreement to prohibit source-to-source translation, thereby blocking translation from Flash (in CS5) and also from Android (via XMLVM). You may also have read about a response by a well-known Adobe developer, and calls to boycott development for the iPhone. Given that this audience is a better representative of the developer community than those who post comments on the NYT, Digg, and other news sites, I was wondering what your opinions were about this decision. Will any of you switch to Android from the iPhone or avoid development on the iPhone as a result of this? Since this is fairly subjective, I am making this a community wiki. Also, please, keep things civil.

  • What's the best way to view/analyse/filter huge traces/logfiles?

    - by oliver
    this seems to be a reoccurring issue: we receive a bug report for our software and with it tons of traces or logfiles. since finding errors is much easier when having a visualization of the log messages/events over time it is convenient to use a tool that can display the progression of events in a graph etc. (e.g. wireshark (http://www.wireshark.org) for analyzing network traffic) what tool do you use for such a purpose? the problem with most tools i used so far is that they mercilessly break down when you feed them huge data traces ( 1GB) so some criteria for such a tool would be: can deal with huge input files ( 1 GB) is really fast (so you don't have to get coffee while a file is loading) has some sort of filtering mechanism

    first of all, I am very new to mac and Iphone development. I have a project, that uses the OpenGL framework. In order to try to get some other aspect of the project to work, I may have fiddled around the developer libraries (it was more then a week ago so i don't remember exactly what I did). now when I try to build the project I get "framework not found OpenGL". I have already uninstall xcode completely: sudo /Developer/Library/uninstall-devtools –mode=all and reinstalled it, but stil the same error.

    - by chaitanya
    Hi, I developed a simple application for iPAD. I want to test the app how it works on the device. I have paid developer licence, and i have added the device id and created the app id and i have downloaded the provisioning profile using both. The same way how we will build the app for iphone i have done for ipad. i have sent the provisioning profile and .ipa file to my friend to load on to the ipad device(same device which i have added in the developer.apple.com). when he tried to drag n drop the provisioning file on to the device from iTunes it is giving below error. "abc.mobileprovision" was not copied on to the iPAD, because it cannot be palyed on this iPAD I am not able to understand what the exact error is. Can anyone please let me know how to dump the applicatio on to the ipad device?

  • How Can I create different selectors for accepting new connection in java NIO

    - by Deepak
    I want to write java tcp socket programming using java NIO. Its working fine. But I am using the same selector for accepting reading from and writing to the clients. How Can I create different selectors for accepting new connection in java NIO, reading and writing. Is there any online help. Actually when I am busy in reading or writing my selector uses more iterator. So If more number of clients are connected then performance of accepting new coneection became slow. But I donot want the accepting clients to be slow // Create a selector and register two socket channels Selector selector = null; try { // Create the selector selector = Selector.open(); // Create two non-blocking sockets. This method is implemented in // e173 Creating a Non-Blocking Socket. SocketChannel sChannel1 = createSocketChannel("hostname.com", 80); SocketChannel sChannel2 = createSocketChannel("hostname.com", 80); // Register the channel with selector, listening for all events sChannel1.register(selector, sChannel1.validOps()); sChannel2.register(selector, sChannel1.validOps()); } catch (IOException e) { } // Wait for events while (true) { try { // Wait for an event selector.select(); } catch (IOException e) { // Handle error with selector break; } // Get list of selection keys with pending events Iterator it = selector.selectedKeys().iterator(); // Process each key at a time while (it.hasNext()) { // Get the selection key SelectionKey selKey = (SelectionKey)it.next(); // Remove it from the list to indicate that it is being processed it.remove(); try { processSelectionKey(selKey); } catch (IOException e) { // Handle error with channel and unregister selKey.cancel(); } } } public void processSelectionKey(SelectionKey selKey) throws IOException { // Since the ready operations are cumulative, // need to check readiness for each operation if (selKey.isValid() && selKey.isConnectable()) { // Get channel with connection request SocketChannel sChannel = (SocketChannel)selKey.channel(); boolean success = sChannel.finishConnect(); if (!success) { // An error occurred; handle it // Unregister the channel with this selector selKey.cancel(); } } if (selKey.isValid() && selKey.isReadable()) { // Get channel with bytes to read SocketChannel sChannel = (SocketChannel)selKey.channel(); // See e174 Reading from a SocketChannel } if (selKey.isValid() && selKey.isWritable()) { // Get channel that's ready for more bytes SocketChannel sChannel = (SocketChannel)selKey.channel(); } } Thanks Deepak

  • Rendering javascript at the server side level. A good or bad idea?

    - by davidhong
    I want to make it clear first: This isn't a question in relation to server-side Javascript or running Javascript server side. This is a question regarding rendering of Javascript code (which will be executed on the client-side) from server-side code. Having said that, take a look at below ASP.net code for example: hlRemoveCategory.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this?');") This is prescribing the client-side onclick event on the server-side. As oppose to: $('a[rel=remove]').bind('click', function(event) { return confirm('Are you sure you want to delete this?'); } Now the question I want to ask is: What is the benefit of rendering javascript from the server-side code? Or the vice-versa? I personally prefer the second way of hooking up client-side UI/behaviour to HTML elements for the following reasons: Server-side does what ever it needs to already, including data-validation, event delegation and etc; and What server-side sees as an event is not necessarily the same process on the client-side. i.e., there are plenty more events on client-side (just look at custom events); and What happens on client-side and on server-side, during an event, could be completely irrelevant and decoupled; and What ever happens on client-side happens on client-side, there is no need for the server to know. Server should process and run what is given to them, how the process comes to life is not really up to them to decide in the event of the client-side events; and so and so forth. These are my thoughts obviously. I want to know what others think and if there has been any discussions on this topic. Topics branching from this argument can reach: Code management: is it easier to render everything from server-side? Separation of concern: is it easier if client-side logic is separated to server-side logic? Efficiency: which is more efficient both in terms of coding and running? At the end of the day, I am trying to move my team to go towards the second approach. There are lot of old guys in this team who are afraid of this change. I just wish to convince them with the right facts and stats. Let me know your thoughts.

  • Connecting two Windows XP with MSMQ

    - by NealWalters
    This question is a cross between a developer and a server setup question. I asked on Serverfault but no answer yet. As a developer, I need to setup a test to see how MSMQ works between two machines, and I'm unclear what to do. I will use C# or BizTalk to do the read/write to/from the queues. I have MSMQ installed on two Windows XP computers. Can I configure them to pass messages back and forth, or do I need an MSMQ server in the middle? If I need an MSMQ server, does the normal MSMQ with Win2003 able to act as that? And then, how do I connect my Windows XP to that Windows 2003 server? Is it a) On screen admin dialog in the MSMQ plug-in to MMC, b) a config file, c) Active Directory, d) something else? Thanks, Neal Walters

  • How to convert an EntityCollection<T> to List<POCOObj>

    - by ggomez
    I have Entity Framework entities Events which have an EntityCollection of RSVP. I want to convert the EntityCollection of RSVP to a generic List< of a POCO class RSVP. So I want EntityCollection - List. What would be the best way to go about achieving this? So far I have this (it's missing the RSVP part) var events = from e in _entities.Event.Include("RSVP") select new BizObjects.Event { EventId = e.EventId, Name = e.Name, Location = e.Location, Organizer = e.Organizer, StartDate = e.StartDate, EndDate = e.EndDate, Description = e.Description, CreatedBy = e.CreatedBy, CreatedOn = e.CreatedOn, ModifiedBy = e.ModifiedBy, ModifiedOn = e.ModifiedOn, RSVPs = ??? }; Thanks.

  • WPF application which calls an API, which needs a message pump

    - by Griffin
    I have a WPF application that calls an API to operate a device (a scanner). This API is COM based, and internally has a hidden window that the scanner sends messsages too. The intent of the API is to turn those windows messages into COM events. The problem is that the WPF application doesn't have a message pump, and therefore none of the messages are being delivered to the hidden window. Therefore none of the events are fired and it looks like the scanner is not responding. How should I create a message loop in the WPF application that will be able to dispatch messages to the invisible window?

  • Light weight C++ SAX XML parser

    - by John Bartholomew
    I know of at least three light weight C++ XML parsers: RapidXML, TinyXML and PugiXML. However, all three use a DOM based interface (ie, they build their own in-memory representation of the XML document and then provide an interface to traverse and manipulate it). For most situations that I have to deal with, I much prefer the SAX interface (where the parser just spits out a stream of events like start-of-tag, and the application code is responsible for doing whatever it wants based on those events). Can anyone recommend a light weight C++ XML library with a SAX interface? Edit: I should also note the Microsoft XmlLite library, which does use a SAX interface. Unfortunately, it's ruled out for me at the moment since as far as I know it's closed source and Windows only (please correct me if I'm wrong on this).

  • Building Asp.net Page code behind correctly

    - by Hagai
    Hi everyone, I need some guidelines about building the code behind of my pages correctly. I mean, I'm building in asp.net for a year now, and mostly using the Page_Load event. (and ofcourse "event handling" the events triggered by the user's actions). I know about the page life cycle and the order of events that happens when a page is requested etc.. . Is it normal that, generally, in a data-driven page, for example, I'm not using any of the "pre_render", "page_unload", "pre_init" etc.. event handlers? or am I missing something here? any guidelines would help me a lot, including links or whatever you think that would instruct me well. thanks.

  • Bring object to the front, in Flash AS3

    - by jimbo
    Hi All, i have the below code, which is basically animating object across the screen, when roll-over happens it pauses the anim, and displays some information. Everything works fine, but when its paused, i wold like that current object to be 'on top' so other items run behind. I have looked at setChildIndex, but didn't have much luck. package { import flash.display.MovieClip; import flash.display.Sprite; import flash.events.MouseEvent; import flash.geom.Point; import flash.events.KeyboardEvent; import flash.events.*; import caurina.transitions.Tweener; import fl.motion.Color; public class carpurchase extends Sprite { public function carpurchase() { var carX = 570; //Set cars var car1:fullCar = new fullCar(); car1.info.alpha = 0; //var c:Color = new Color(); //c.setTint(0xff0000, 0.8); //car2.car.transform.colorTransform=c; car1.x = carX; car1.y = 280; car1.info.title.text = "test"; car1.info.desc.text = "test"; addChild(car1); car1.addEventListener(MouseEvent.ROLL_OVER, carPause); car1.addEventListener(MouseEvent.ROLL_OUT, carContinue); function car1Reset():void { Tweener.addTween(car1, {x:carX, time:0, onComplete:car1Tween}); } function car1Tween():void { Tweener.addTween(car1, {x:-120, time:2, delay:3, transition:"linear", onComplete:car1Reset}); } car1Tween(); var car2:fullCar = new fullCar(); car2.info.alpha = 0; var c:Color = new Color(); c.setTint(0xff0000, 0.8); car2.car.transform.colorTransform=c; car1.x = carX; car2.y = 175; car2.info.title.text = "test"; car2.info.desc.text = "test"; addChild(car2); car2.addEventListener(MouseEvent.ROLL_OVER, carPause); car2.addEventListener(MouseEvent.ROLL_OUT, carContinue); function car2Reset():void { Tweener.addTween(car2, {x:carX, time:0, onComplete:car2Tween}); } function car2Tween():void { Tweener.addTween(car2, {x:-120, time:3, delay:0, transition:"linear", onComplete:car2Reset}); } car2Tween(); function carPause(e:MouseEvent):void { Tweener.pauseTweens(e.target); Tweener.addTween(e.target.info, {y:-150, alpha:1, time:.5, transition:"easeout"}); } function carContinue(e:MouseEvent):void { Tweener.addTween(e.target.info, {y:10, alpha:0, time:.5, transition:"easeout"}); Tweener.resumeTweens(e.target); } } } Any help welcome

  • ActionScript Clean Up

    - by TheDarkIn1978
    i want to deallocate a spriteClass from memory and remove it from the display list. when the spriteClass is instantiated, it creates some of it's own sprites with new tweens and tween events and add them as children. i understand that the tween events must be removed in order for the spritClass to become available for garbage collection, and only afterwards should i nullify the spriteClass, but should i also nullify and remove the spriteClass's sprite children and tweens as well, or does it not matter? essentially i'd like to know if by nullifying the spriteClass it automatically removes all of it's added children and new instantiations like tweens, sprites, rects, whatever, or am i responsible for removing them all and otherwise the spriteClass isn't truly null until i do so?

  • Dynamically load .asmx web-service

    - by Tierney
    I have an .aspx page that can perform a number of functions. The type of function is determined at run-time depending on which button the user clicks. This makes makes a web-service call to an .asmx method. The web-service call returns html and javascript which then become part of the original page. This new content has javascript events attached to button clicks, data validation etc. In turn these events then call their own web-service methods in another .asmx file. The main page does not know about these other .asmx files when the page loads. So, is there any way of dynamically loading these .asmx files on demand?

  • Customising event delegates in the jQuery validation plug-in

    - by Russell
    I am currently setting up the jQuery validation plug-in for use in our project. By default, there are some events automatically set up for handling. I.e. focus in/out, key up events on all inputs fire validation. I want it to only fire when the submit button is clicked. This functionality seems to be in-built into the plug-in, which is making it difficult to do this (without modifying the plug-in code, Not What I Want To Do). I have found the eventDelegate function calls in the plugin code prototype method: $(this.currentForm) .validateDelegate(":text, :password, :file, select, textarea", "focusin focusout keyup", delegate) .validateDelegate(":radio, :checkbox, select, option", "click", delegate); When I remove these lines from the plug-in I get my result, however I would much rather do something Outside the plug-in to achieve this. Can anybody please help me? If you need any more details, please let me know. I have searched google with little success. Thanks

  • Adding UIComponent to both Canvas and Tree in Flex 3

  • Giving event control back to xaml/callee to access check/uncheck

    - by dovholuk
    Hi All, I've scoured the Internet but my search-foo must not work if it's out there cause I just can't find the proper search terms to get me the answer I am looking for. So I turn to the experts here as a last resort to point me in the right direction. What I'm trying to do is create a composite control of a text box and a list box but I want to allow the control consumer to decide what to do when say the checkbox is checked/unchecked and I just can't figure it out... Maybe i'm going about it all wrong. What I've done thus far is to: create a custom control that extends ListBox expose a custom DP named "Text" (for the Text box but it's not the important part) craft the generic.xaml so that the list items have a default ItemTemplate/DataTemplate inside the DataTemplate I'm trying to set the "Checked" or "Unchecked" events expose 'wrapper' events as DPs in the custom control that would get 'set' via the template when instatiated As soon as I try something like the following (inside generic.xaml): <DataTemplate> <...> <CheckBox Checked="{TemplateBinding MyCheckedDP}"/> <...> </DataTemplate> I get runtime exceptions, the designer - vs2010 - pukes out a LONG list of errors that are all very similar and nothing I do can make it work. I went so far as to try using the VisualTreeHelper but no magic combination I could find would work nor would it allow me to traverse the tree because when the OnApplyTemplate method fires the listbox items don't exist yet and aren't in the tree. So hopefully this all makes sense but if not please let me know and I'll edit the post for clarifications. Thanks to all for any pointers or thoughts... Like I said maybe I'm heading about it in the wrong way from the start... EDIT (Request for xaml) generic.xaml datatemplate: <DataTemplate > <StackPanel Orientation="Horizontal" > <local:FilterCheckbox x:Name="chk"> <TextBlock Text="{Binding Path=Display}" /> </local:FilterCheckbox> </StackPanel> </DataTemplate> usercontrol.xaml (invocation of custom control) <local:MyControl FancyName="This is the fancy name" ItemChecked="DoThisWhenACheckboxIsChecked" <-- this is where the consumer "ties" to the checkbox events ItemsSource="{Binding Source={StaticResource someDataSource}}" />

  • Java->Scala Remove Iterator<T>-Element from a JavaConversions-wrapped Iterable

    - by ifischer
    I have to translate the following code from Java to Scala: for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) { ExceptionQueuedEvent event = i.next(); try { //do something } finally { i.remove(); } } I'm using the JavaConversions library to wrap the Iterable. But as i'm not using the original Iterator, i don't know how to remove the current element correctly from the collection the same way as i did in Java: import scala.collection.JavaConversions._ (...) for (val event <- events) { try { //do something } finally { //how can i remove the current event from events? } } Can someone help me? I guess it's easy, but i'm still kinda new to Scala and don't understand what's going on when Scala wraps something of Java.

  • How do you share your git repository with other developers?

    - by semi
    I have a central git repository that everyone pushes to for testing and integration, but it only is pushed to when features are 'ready'. While in the middle of a big task, developers frequently have many commits that stay on their harddrives. Sometimes in the middle of these projects I'd like to either see what another developer is doing, or show him how I've done something. I'd like to be able to tell another developer to just "pull my working copy" The only way I can think of is having everyone run ssh on their development machines and adding accounts or ssh keys for everyone, but this is a huge privacy and permissions nightmare, and seems like a lot of work to maintain. Should we just be pushing to that central repository in these cases? Should we be pushing after every local commit?
