  • In flex how do I pass data retrieved from a remote object service to a modules interface?

    - by Dan G
    I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use? I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.

  • Can any JavaScript library perform as well as the Cut The Rope JavaScript implementation?

    - by joe
    Now that the canvas tag is starting to get hardware execration [acceleration - thanks guys!] by many browsers, developing casual games in HTML5 is becoming more feasible. ZeptoLabs did a great job porting Cut The Rope to HTML5 for use as a Windows 8 Metro App. You can find some of the details here but they do not get into specifics. I was wondering if anyone knew if they used a library (such as Impact or Crafty) or if you need to write all custom and optimized JavaScript code in order to get this type of performance. Thanks!

  • why does Visual Studio not enforce try-catch-block implementation?

    - by Pedro
    Coming from Eclipse/Java, I noticed that in VisualStudio/C# it is not mandatory to care about Exceptions. While Eclipse forces the user to implement a try-catch-block or to add a throws declaration, this is not the case in Visual Studio. What is the reason Visual Studio doesn't inform about unhandled exceptions? Can I configure Visual Studio to force me to implement try-catch-blocks, or at least add a compiler-warning?

  • Why does jQuery do this in its constructor function implementation?

    - by mattcodes
    If we look at the latest jQuery source at http://code.jquery.com/jquery-latest.js we see the following: var jQuery = function( selector, context ) { // The jQuery object is actually just the init constructor 'enhanced' return new jQuery.fn.init( selector, context ); } My understanding of the new keyword in Javascript is essentially JavaScript passes the function an empty object {} and the function sets stuff on it via this.blah. Also from my understanding new differs from .call/.apply etc.. in that the return object also has the prototype set to that of the function. So the return value should have a prototype that the same as jQuery.prototype.init.prototype (or jQuery.fn.init.prototype). However from what I see its prototype is set to jQuery.prototype thus all the commands available to work on the set. Why is this? What am I missing in my understanding?

  • Why is my implementation of strcmp not returning the proper value?

    - by Avanish Giri
    Why is this printing out 0 back in main but 6 when it is inside of the strcmp function? 7 int main() 8 { 9 char* str = "test string"; 10 char* str2 = "test strong"; 11 //printf("string length = %d\n",strlen(str)); 12 13 int num = strcmp(str,str2); 14 15 printf("num = %d\n",num); 16 } 29 int strcmp(char* str, char* str2) 30 { 31 if(*str == '\0' && *str2 == '\0') 32 return 0; 33 if(*str2 - *str == 0) 34 { 35 strcmp(str+1,str2+1); 36 } 37 else 38 { 39 int num = *str2 - *str; 40 cout << "num = " <<num<<endl; 41 return num; 42 } 43 } The output is: num = 6 num = 0 Why is it printing 0 when obviously the value that it should be returning is 6?

  • Is there a way to attach Ruby Net::HTTP request to a specific IP address / network interface?

    - by Dan Sosedoff
    Hello, Im looking a way to use different IP addresses for each GET request with standard Net::HTTP library. Server has 5 ip addresses and assuming that some API`s are blocking access when request limit per IP is reached. So, only way to do it - use another server. I cant find anything about it in ruby docs. For example, curl allows you to attach it to specific ip address (in PHP): $req = curl_init($url) curl_setopt($req, CURLOPT_INTERFACE, 'ip.address.goes.here'; $result = curl_exec($req); Is there any way to do it with Net::HTTP library? As alternative - CURB (ruby curl binding). But it will be the latest thing i`ll try. Suggestions / Ideas?

  • Is there any documentation for the Cassandra Erlang interface?

    - by Zubair
    I have looked everywhere, and to use Cassandra from Erlang you end up having to download (amongst others): boost thrift : and then you have generate the erlang library by hand, and then copy lib files and beams files. Once you have the whole thing working there is absolutely zero documentation anywhere. If anyone could show me some user friendly documentation it would be much appreciated.

  • Text-based one-on-one chat with Flash interface: what to power the backend?

    - by Zachary Burt
    Hey guys. I'm building a website where I hook people up so that they can anonymously vent to strangers. You either choose to be a listener, or a talker, and then you get catapulted into a one-on-one chat room. The reason for the app's construction is because you often can't vent to friends, because your deepest vulnerabilities can often be leveraged against you later on. (Like it or not, this is a part of human nature. Sad.) I'm looking for some insight into how I should architect everything. I found this neat tutorial, http://giantflyingsaucer.com/blog/?p=875, which suggests using python & stackless + flash. Someone else suggested I should try using p2p sockets, but I don't even know where to begin to look for info on that. Any other suggestions? I'd like to keep it simple. :^)

  • Where does the delete control go in my Cocoa user interface?

    - by Graham Lee
    Hi, I have a Cocoa application managing a collection of objects. The collection is presented in an NSCollectionView, with a "new object" button nearby so users can add to the collection. Of course, I know that having a "delete object" button next to that button would be dangerous, because people might accidentally knock it when they mean to create something. I don't like having "are you sure you want to..." dialogues, so I dispensed with the "delete object". There's a menu item under Edit for removing an object, and you can hit Cmd-backspace to do the same. The app supports undoing delete actions. Now I'm getting support emails ranging from "does it have to be so hard to delete things" to "why can't I delete objects?". That suggests I've made it a bit too hard, so what's the happy middle ground? I see applications from Apple that do it my way, or with the add/remove buttons next to each other, but I hate that latter option. Is there another good (and preferably common) convention for delete controls? I thought about an action menu but I don't think I have any other actions that would go in it, rendering the menu a bit thin.

  • Implement Combobox/Option Menu funcionality on an iPhone interface?

    - by MikeN
    I want to give a list of choices on an iPhone GUI that works like a Combobox/Option menu. It needs to display the current selection, but on tapping it you should be able to change the current selection which will trigger a refresh of the screen. The option menu is letting the user choose which category a search is being performed under. So there is a default category and there are about 6 other choices. Idea 1: Use a label or button and when clicked on a new screen overlays that has all 6 options in a tableview, clicking on one closes the overlay screen and goes back to the main page with the updated value displayed. Idea 2: Should I use a totally different but native iPhone GUI widget like a Navbar at the bottom of the screen to reflect the different options?

  • Is there a way to reference a certain class/interface/... by enclosing it with its namespace rather than a using directive "using namespace_name" ?!

    - by Ahmed
    Is there a way to reference a certain class/interface/... by enclosing it with its namespace rather than a using directive "using namespace_name" ?! As, I'm working on a website, which uses SAP .NET connector. I already added a reference for connector ddl, and while referencing its namespace "using namespace_name", or set class namespace to another one rather than connector namespace, I got error regarding connector classes with that error message "The type or namespace couldn't be found, are you missing a using directive or an assembly reference?". But while changing namespace name to connector namespace, everything is going well?! // Set namespace to be IDestinationConfiguration interface namespace. namespace SAP.Middleware.Connector { public class ConnectorConfiguration : IDestinationConfiguration { } } So, connector types forced me to set namespace of class to their namespace! Is this possible? If so, how?

  • Optional parameters for interfaces

    - by bryanjonker
    Using c# 4.0 -- building an interface and a class that implements the interface. I want to declare an optional parameter in the interface and have it be reflected in the class. So, I have the following: public interface IFoo { void Bar(int i, int j=0); } public class Foo { void Bar(int i, int j=0) { // do stuff } } This compiles, but it doesn't look right. The interface needs to have the optional parameters, because otherwise it doesn't reflect correctly in the interface method signature. Should I skip the optional parameter and just use a nullable type? Or will this work as intended with no side effects or consequences?

  • Is using a GUI worse than using bash and other text interface tools?

    - by Glycerine
    As a freelancer, and previous Adobe trainer, I get a look-in at many development workflows and alternate styles of programming and design and therefore quite open to different workflows. But a recent post I had, I needed to use SQL - so I whipped out navicat and wrote a nice join statement. I had sniggering comments and sideways glances when I told the developers I was working with navicat, I preferred a GUI to bash and I prefer Aptana to notepad. I felt a little insulted and under skilled as I didn't want to sit in front of reams of spewing green text. I know and use the tools when required but I prefer more attractive, modern products. Have you guys had this? What do you do to overcome it - apart from using bash and notepad more? How do you subdue a developer who's being arrogant about his skill? And is it my fault? I hope this question is not subjective, I do feel like I am inferior to my peers due to it - so some advise would really help.

  • Is XML-RPC bad used as a protocol for a public API implementation?

    - by Jack Duluoz
    I need to implement a web API for a project I'm working on in this period. I read there are many standard protocols to do it: XML-RPC, SOAP, REST. Apparently, the XML-RPC one is the easiest one to implement and use from what I saw, but I didn't find anything about using it to implement an API. Instead I found many tutorial about creating a REST API in PHP, for example. Is there any counter-indication for using XML-RPC to implement a public web API? Also, more generally speaking, I could (sort of) define a custom protocol for my API, to keep things simpler (i.e. accepting only GET request containing the parameters I need): would this be so bad? Is using a standard protocol a must-do?

  • Can Spring understand @Inject replacing Weld as a JSR-299 implementation?

    - by Thorbjørn Ravn Andersen
    I have noticed from several web pages that apparently Spring 3.0 supports @Inject from JSR-330. As we would really like to use JSR-299 syntax for dependency injection in our libraries for both web apps and stand-alone applications, and have alternatives to Weld, it would be nice if Spring could do this. Being a novice to Spring, I tried downloading the Spring Framework distribution and put all jars on the Eclipse build path. No Inject annotation so my existing test project using Weld did not compile. Can this be done with Spring? What do I need to do to get it running? (I am aware that Guice eventually will support this too. It is only in SVN for now, and if there is an official Spring release which can, that would be better.)

  • How does one go about writing a virtual MIDI interface?

    - by Alex
    I want to do some funky things with controlling MIDI streams, and I'd like to be able to pipe MIDI input into an application like Ableton or Reason. Presumably this involves some sort of driver level work? Ultimately I'd like to write my application in Python, so if there is some Python-based solution, I'd consider it. I'm perfectly fine with using C/C++, though, so that's not a problem.
