  • How to deal with JSON output that might be an array, or might be a value

    - by Summer
    Hi - I'm getting JSON-encoded output from another organization's API. In many cases, the output can be either an array of objects (if there are many) or an object (if there's just one). Right now I'm writing tortured code like this: if ( is_array($json['candidateList']['candidate'][0]) ) { foreach ($json['candidateList']['candidate'] as $candidate) { // do something to each object } } else { // do something to the single object } How can I handle it so the "do something" part of my code only appears once and uses a standard syntax?

  • UnsupportedOperationException on Collection

    - by Duke Vador
    While studying the Collection API, we find that some methods (add, remove,...) may throw a java.lang.UnsupportedOperationException if the current implementation of the Collection does not support those functionalities. Is there,actually, in the JDK, a concrete Collection that does not support those methods ? Thanks a lot for your answers.

  • How does joomla breadcrumbs work internally?

    - by user543087
    I've already gone thru: http://docs.joomla.org/How_to_add_breadcrumbs and http://api.joomla.org/Joomla-Framework/Application/JPathway.html but they don't help. I have not found any more info in any books or internet. My website download forms has 1000's of pages generated thru script. I want to generate breadcrumb navigation for the pages. Google has refused me Adsense account due to this lack of navigation.

  • Autohide scrollbars when not scrolling in a ListView

    - by synic
    In the new official Twitter app, the scrollbars in all the ListViews the app uses are hidden unless the user is scrolling through the list. When you start scrolling, the scrollbars appear. When you stop, they fade out with an animation until they are gone completely. I can't seem to find anything in the documentation that indicates this as being a standard feature. Is this something included in the API? If not, anyone know how this might be done?

  • How to generate android styled javadocs ?

    - by Kaillash
    Hi, Is it possible to generate android styled javadocs for my android project (like http://developer.android.com/reference/java/lang/String.html, instead of http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html) Is it something regarding using of some custom doclet instead of standard doclet? If yes, then which one I have to use?

  • Help with \0 terminated strings in C#

    - by Joshua
    I'm using a low level native API where I send an unsafe byte buffer pointer to get a c-string value. So it gives me // using byte[255] c_str string s = new string(Encoding.ASCII.GetChars(c_str)); // now s == "heresastring\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0(etc)"; So obviously I'm not doing it right, how I get rid of the excess?

  • UIViewController is popped from view stack and NSURLConnection crashes the application

    - by rickharrison
    I am pushing a UIViewController onto a UINavigationController. This view controller immediately starts a download of an xml feed and then parses it. However, if you hit the back button before it is done downloading, and crashes with EXC_BAD_ACCESS. The line that is crashing it is in parserDidEndDocument and is this line: if (self.delegate && [self.delegate conformsToProtocol:@protocol(ModelDelegate)]) [self.delegate modelDidFinishParsing:self]; I assume it is crashing because it is trying to access self.delegate which is not assigned anymore. How do I get around this? Also, I would release the model object in the modelDidFinishParsing method. How would I release this model if it never reaches this method.

  • .Net - Whats the difference between a Session Facade and Business Delegate?

    - by KP65
    What I understand so far: Business Delegate - In the presentation tier, as an ASP component, provides an interface for ASP views to access business components without exposing their API, therefore reducing coupling between the two. Session Facade - In the business tier, as a com+ component, encapsulates business objects, provides a course grain interface for views to access business components. Reduces coupling, hides complex business component interaction from views. So what is the actual difference? They seem pretty similar to me..

  • Android playing Video data from a custom network stream?

    - by Cinar
    Does Android MediaPlayer can only work with file sources? I would like play media (video) from a network stream, but the stream comes in a non-standard protocol, so I have to somehow feed Android MediaPlayer with the data only. Is there anyway to do that? I found a few web pages suggesting using a temporary file for the buffered media data etc. but I would like to minimize the I/O usage as much as I can, so I'm looking for a API only solution if there is any? how about JNI? but looks like the permissions going to be an issue with that also.

  • Can I expose MySQL data using PHP and OData?

    - by user359796
    As I understand it, OData is just a standardized way to expose relational data RESTfully. If I've got a PHP application, it should be able to process those RESTful requests and manipulate a MySQL database based on the request data and then return an ATOM feed. First, are the preceeding statements correct? Second, does a PHP library to do this already exist or would I have to create my own? If I have completely misunderstood these technologies and my question doesn't make sense, please feel free to let me know.

  • How should I handle multiple links ot the same page with different Query Strings

    - by RandomBen
    In the website I am working on, there is a product page with 8 tabs on it, showing different aspects of the product. There are quick links on other pages within the site that take you to the page and to a specific link specified by a query string. For example the base page would be www.example.com/Product1. And then there are links like this: www.example.com/Product1?tab=CADDrawing www.example.com/Product1?tab=Schematics www.example.com/Product1?tab=Reviews My concern is that Google sees each of these links as a different URL but they aren't and the data on the page is 100% the same. Is there any easy way to make it so Google either knows that www.example.com/Product1 is the base page or doesn't follow the links with Query Strings? I thought about using rel="nofollow" but that seems like it would actually hurt my page ranking. Most of the websites, including Googles on webmaster pages, is unclear. The other option is to add the rel="canonical" to the pages that have a query string but not to the base page. Does that succeed in stopping all of the noisy links?

  • Check whether a folder is a local or a network resource in .NET

    - by rwmnau
    Is there a quick way to check whether a path I have is on a local disk or somewhere on the network? I can't just check to see if it's a drive letter vs. UNC, because that would incorrectly identify mapped drives as local. I assumed it would be a boolean in the DirectoryInfo object, but it appears that it's not. I've found classic VB code to do this check (through an API), but nothing for .NET so far.

  • What different terms mean the same thing (or don't, but people think they do)?

    - by Matthew Jones
    One of the pitfalls I run into on a daily basis is customers saying one thing while meaning another. Usually, this is just due to a miscommunication somewhere, but occasionally they are, in fact, saying the same thing I am just using a different term. For example, one of my customers the other day mentioned a feature he called, "find as you type." Being a little confused, I asked him what he meant, and he described the feature in Google where, once you start typing a search query, Google suggests other, popular queries that match the letters you have typed. Click! He meant AutoComplete! He was not wrong, it is just that I had never heard that term before. In the spirit of reducing confusion, what terms can you think of that are different but mean, essentially, the same thing? Also, what terms do people think mean the same thing, but don't. Please differentiate between the two. Please only one set of terms per answer, so we can vote on the best ones.

  • Compilation problem in the standard x86_64 libraries

    - by user350282
    Hi everyone, I am having trouble compiling a program I have written. I have two different files with the same includes but only one generates the following error when compiled with g++ /usr/lib/gcc/x86_64-linux-gnu/4.4.1/../../../../lib/crt1.o: In function `_start': /build/buildd/eglibc-2.10.1/csu/../sysdeps/x86_64/elf/start.S:109: undefined reference to `main' collect2: ld returned 1 exit status The files I am including in my header are as follows: #include <google/sparse_hash_map> using google::sparse_hash_map; #include <ext/hash_map> #include <math.h> #include <iostream> #include <queue> #include <vector> #include <stack> using std::priority_queue; using std::stack; using std::vector; using __gnu_cxx::hash_map; using __gnu_cxx::hash; using namespace std; Searching the internet for those two lines hasn't resulted in anything to help me. I would be very grateful for any advice. Thank you
