  • Rails: What's the suggested approach to retrieve xml from an outside source

    - by Syrahn
    Rails newbie (though long time programmer) here. I'm writing an test app that retrieves data from several outside sources (think Twitter, RSS feeds, etc.) and under certain circumstances, it stores that data in a db (or presents it to the user). The data model and the views are trivial. What I'm having difficulty with is making the actual xml HTTP call to the outside source and deserialize the xml response so I can query/use it in my controller/helper. What library/gem should I use to accomplish this? I tried looking this up around the net, but only came up with some article from 2006 which, knowing how fast Rails has developed, might well be completely deprecated. Your help is much appreciated.

  • ByteArrayOutputStream to PrintWriter (Java Servlet)

    - by Thomas
    Writing generated PDF (ByteArrayOutputStream) in a Servlet to PrintWriter. I am desperately looking for a way to write a generated PDF file to the response PrintWriter. Since a Filter up the hierarchy chain has already called response.getWriter() I can't get response.getOutputStream(). I do have a ByteArrayOutputStream where I generated the PDF into. Now all I need is a way to output the content of this ByteArrayOutputStream to the PrintWriter. If anyone could give me a helping hand would be very much appreciated!

  • C++ operator[] syntax.

    - by Lanissum
    Just a quick syntax question. I'm writing a map class (for school). If I define the following operator overload: template<typename Key, typename Val> class Map {... Val* operator[](Key k); What happens when a user writes: Map<int,int> myMap; map[10] = 3; Doing something like that will only overwrite a temporary copy of the [null] pointer at Key k. Is it even possible to do: map[10] = 3; printf("%i\n", map[10]); with the same operator overload?

  • Get Links in class with html agility pack

    - by acidzombie24
    There are a bunch of tr's with the class alt. I want to get all the links (or the first of last) yet i cant figure out how with html agility pack. I tried variants of a but i only get all the links or none. It doesnt seem to only get the one in the node which makes no sense since i am writing n.SelectNodes html.LoadHtml(page); var nS = html.DocumentNode.SelectNodes("//tr[@class='alt']"); foreach (var n in nS) { var aS = n.SelectNodes("a"); ... }

  • What happens if you break out of a Lock() statement?

    - by cyclotis04
    I'm writing a program which listens to an incoming TcpClient and handles data when it arrives. The Listen() method is run on a separate thread within the component, so it needs to be threadsafe. If I break out of a do while loop while I'm within a lock() statement, will the lock be released? If not, how do I accomplish this? Thanks! (Any other advice on the subject of Asynchronous TCP Sockets is welcome as well.) private void Listen() { do { lock (_client) { if (!_client.Connected) break; lock (_stateLock) { if (!_listening) break; if (_client.GetStream().DataAvailable) HandleData(); } } Thread.Sleep(0); } while (true); }

  • PHP: How to begin testing large, existing codebase, and test for regression on production site?

    - by anonymous coward
    I'm in charge of at least one large body of existing PHP code, that desperately needs tests, and as well I need some method of checking the production site for errors. I've been working with PHP for many years, but am unfortunately new to testing. (Sorry!). While writing tests for code that has predictable outcomes seems easy enough, I'm having trouble wrapping my head around just how I can test the live site, to ensure proper output. I know that in a test environment, I could set up the database in a known state... but are there proper methods or techniques for testing a live site? Where should I begin? [I am aware of PHPUnit and SimpleTest, but haven't chosen one over the other yet]

  • Cannot attach to a service in VS 2008

    - by rhj4
    I have created a service in VS 2008 called EmailReader. I have compiled, installed and started the service. Its timer loop is writing records to a log file, so I can see that it is running. I am trying to attach to it in VS 2008, but the process name is greyed out in the list of available processes, and the name is "EmailReader.vshost.exe" instead of "EmailReader.exe". There is probably a simple answer, but I don't know it. Do you?

  • 2 different ways to define a widget in symfony, which to use?

    - by fayer
    in the tutorial i can use either: public function configure() { $this->setWidgets(array( 'type' => new sfWidgetFormChoice(array( 'choices' => Doctrine_Core::getTable('Gender')->getTypesForForm(), 'expanded' => false, 'multiple' => false, )) )); $this->widgetSchema['type'] = new sfWidgetFormChoice(array( 'choices' => Doctrine_Core::getTable('Gender')->getTypesForForm(), 'expanded' => false, 'multiple' => false, )); } to define a widget. i wonder which i should use and why there is 2 ways of writing this? thanks

  • travesersing the dom with inexact parameters

    - by rashcroft23
    Hi, I want to grab the image src on a product page in a e commerce website. I'm writing this as a bookmarklet, so I'd like the code to work universally as possible. I've noticed that there are only two reoccurring factors in the product image tag among top e-commerce websites (amazon, bestbuy ect.): border=0 and 180<width&height<400. So how could I write a selector that would give me the srcof the first img element on the page with no border and width & height between 180 and 400 px? Or is there a better way of doing this? P.S. since I'm trying to keep the bookmarklet as light as possible, I don't want to use any libraries (jquery, yui etc)

  • how to use ByteArrayOutputStream and DataOutputStream simultaneously (Java)

    - by Manuel
    Hi! I'm having quite a problem here, and I think it is because I don't understand very much how I should use the API provided by Java. I need to write an int and a byte[] into a byte[] I thought of using a DataOutputStream to solve the data writing with writeInt(int i) and write(byte[] b), and to be able to put that into a byte array, I should use ByteArrayOutputStream's method toByteArray(). I understand that this classes use the Wrapper pattern, so I had two options: DataOutputStream w = new DataOutputStream(new ByteArrayOutputStream()); or ByteArrayOutputStream w = new ByteArrayOutputStream(new DataOutputStream()); but in both cases, I "loose" a method. in the first case, I can't access the toByteArray method, and in the second, I can't access the writeInt method. How should I use this classes together?

  • Keeping Score in XNA Game

    - by Seven
    Hi. I'm following an XNA tutorial and have the following code for collision detecting (detecting when a bullet collides with a target). Basically I'm looking to increment a score variable to display the score to the screen without re-writing the whole program. No matter where I place it in this method it seems to start incrementing from the number of targets, not from zero. Is there something simple I'm missing here? Any help would be greatly appreciated. Thanks. private CollisionType CheckCollision(BoundingSphere sphere) { if (completeCityBox.Contains(sphere) != ContainmentType.Contains) return CollisionType.Boundary; for (int i = 0; i < targetList.Count; i++) { if (targetList[i].Contains(sphere) != ContainmentType.Disjoint) { targetList.RemoveAt(i); i--; AddTargets(); return CollisionType.Target; } } return CollisionType.None; }

  • Increase a recive buffer in UDP socket

    - by unresolved_external
    I'wm writing an app, which transmits video and obviously uses UDP protocol fot this purpose. So I am wondering how can I increase a size of send/recieve buffer, cause currently the maximal size of data, which I can send is 65000 bytes. I already tried to do it in following way: int option = 262144; if(setsockopt(m_SocketHandle,SOL_SOCKET,SO_RCVBUF ,(char*)&option,sizeof(option)) < 0) { printf("setsockopt failed\n"); } But it did not work. So how can I do it?

  • How can I pass a type as a parameter in scala?

    - by rsan
    I'm having a really hard time trying to figure out how can I store or pass a type in scala. What I want to achive is something like this: abstract class Foo( val theType : type ) object Foo{ case object Foo1 extends Foo(String) case object Foo2 extends Foo(Long) } So at some point I can do this: theFoo match{ case String => "Is a string" case Long => "Is a long" } and when obtaining the object being able to cast it: theFoo.asInstanceOf[Foo1.theType] Is this possible? If is possible, is a good aproach? What I'm trying to achieve ultimately is writing a pseudo schema for byte stream treatment. E.g if I have an schema Array(Foo1,Foo1,Foo2,Foo3,Foo1) I could parse Arrays of bytes that complain with that schema, if at some point I have a different stream of bytes I could just write a new schema Array(Foo3, Foo4, Foo5) without having to reimplement parsing logic. Regards,

  • SVN user guidelines

    - by Oliver Moran
    I have been tasked with writing a set of user guidelines for SVN for developers in my company. The guidelines are to be solely from a user perspective (e.g. commit comments, when to commit) and not from an administrative perspective (e.g. when to tag, how to structure). An administrative guideline will be written in a separate document. We are an app development house involved also in embedded development. So our developers range from HTML5 and Flash to Java and C. Some of our coding involves forking very large (millions of files) code bases. Other parts involve us engaging in ground-up development. Are there any best practices for use of SVN from a user (i.e. grunt developer) perspective?

  • Ternary operator or chosing from two arrays with the boolean as index

    - by ajax333221
    Which of these lines is more understandable, faster jsPerf, easier to maintain?: arr = bol ? [[-2,1],[-1,2]] : [[-1,0],[-1,1]]; //or arr = [[[-1,0],[-1,1]], [[-2,1],[-1,2]]][bol*1]; I usually write code for computers (not for humans), but this is starting to be a problem when I am not the only one maintaining the code and work for a team. I am unsure, the first example looks neat but are two different arrays, and the second is a single array and seem to transmit what is being done easier. I also considered using an if-else, but I don't like the idea of writing two arr = .... Or are there better options? I need serious guidance, I have never worried about others seeing my code.

  • Backbone.js: How to utilize router.navigate to manipulate browser history?

    - by Xavier_Ex
    I am writing something like a registration process containing several steps, and I want to make it a single-page like system so after some studying Backbone.js is my choice. Every time the user completes the current step they will click on a NEXT button I create and I use the router.navigate method to update the url, as well as loading the content of the next page and doing some fancy transition with javascript. Result is, URL is updated which the page is not refreshed, giving a smooth user experience. However, when the user clicks on the back button of the browser, the URL gets updated to that of a previous step, but the content stays the same. My question is through what way I can capture such an event and currently load the content of the previous step and present that to the user? Or even better, can I rely on browser cache to load that previously loaded page? EDIT: in particular, I'm trying something like mentioned in this article.

  • looping and arrays

    - by user1838418
    Hi I'm trying to construct a loop to execute 16 states of the 8 4 2 1 code in (C++) while( condition) { double Bubble[16], Bubble1[16]; Bubble[0] = ( a-2 - (b-2) ) + ( c-2 - (d-2)); // represents 0000 Bubble[1] = ( a-2 - (b-2) ) + ( c-2 - (d+2)); // represents 0001 Bubble[2] = ( a-2 - (b-2) ) + ( c+2 - (d-2)); // represents 0010 Bubble[3] = ( a-2 - (b-2) ) + ( c+2 - (d+2)); //represents 0011 ....... Bubble[15] =(a+2 - (b+2) ) + ( c+2 - (d+2)); //represents 1111 } Is there an easy way of coding using for loops? instead of writing bubble[] every time? 0 stands for -2 and 1 stands for +2. So I have 4 variables and each one need to be incremented and/or decremented. Can this be done using for loop? Appreciate your help

  • Methods of sending web-generated config files to servers and restarting services.

    - by JPG
    Hi, We're writing a web-based tool to configure our services provided by multiple servers. This includes interfaces configuration, dhcp configs etc. etc. Having configs in database and views that generate proper output, how to send it/make it available for servers? I'm thinking about sending it through scp and invoking reload command to services through ssh. I'm also thinking about using Func to do all the job, as this is Python tool and will seemingly integrate with python-based (django) config tool. Any other proposals?

  • how to remove error text from the email format checker code?

    - by rdesai
    I have been writing a code for validating forms using javascript/jquery. Following is a code snippet for checking email format. The problem is when I enter invalid email, it recognizes it, but when I go back to this field and enter correct email, the error text still stays even though I have used the 'else' part. How do I remove the error text in this case? if(e1.value!=''){ var emailRegEx = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i; if (document.signupForm.email1.value.search(emailRegEx) == -1) { $("#err_email1").html("Please enter valid email address."); } status=0; } else{ $("#err_email1").html(""); status=1; }

  • How can I modify the application file of an application that is currently running (on Linux)?

    - by Hach-Que
    I have an application running called AppFS. This application has an ext2 filesystem just attached to the end of the file (it's positioned so that the application binary exists in a 1MB spacing area, followed by the ext2 data). Now I've got FUSE embedded in the program and I've managed to extract the filesystem out of the application data into a temporary file so that FUSE can mount / use it. The problem I have now is writing the temporary file back into the application file. I get "Text file busy" presumably because the application has locked itself and won't let writes occur. Is there a way I can force the file to become unlocked so I can write data to it? (It's important to note that I'm not changing the application binary area - just rewriting the ext2 component.) It needs to be unlocked without requiring root permissions (unlocked by the same user who started the application).

  • Zoom controls not showing when using a MapView with fill_parent

    - by Joe
    Hey everyone I am working on an applications and I am using the built in zoom controls. When using a specific size I can see the zoom controls. When using fill_parent the zoom controls are not visible. How it is setup is a mapview inside of a frame layout(also using fill parent for the height and width but with an offset down the screen. The only thing I can think of is the fill parent issue is with the framelayout and the zoom controls are off the screen. Sorry if this is confusing, I confused myself writing it. Thanks in advance

  • Delete files in C# that windows does not want me to delete?

    - by user315881
    At my company, we are writing a script to take care of simple tasks that we usually would do by hand. I am using c# to delete profiles in c:\documents and settings\, except a few. These will simply be left alone. The problem is that even with code that sets the files to normal and marks the admin user as an owner, they won't delete. They say that the quick launch folder has access denied. I am using a recursive permissions change method and I know that it works. Same thing with file attributes. Why won't it work? How do I fix this?

  • Singly-Linked Lists insert_back and isIncreasing

    - by rezivor
    I just finished writing a program that I can add, remove or print objects to a list, but I am having difficulty implementing two more functions that is insert_back, which inserts a value to the end of a list. Also,I have to modify the representation of a List and alter whatever methods are necessary to make insert_back run in constant time: O(1). This new operation should have the signature: void List::insert_back( const Object& data ); Also, isIncreasing, For example, for a list containing head-() (11) (8) (15) (3), isIncreasing() should return false. However, it would return true when working on a list containing head- () (7) (9) (15). This new operation should have the signature: bool List::isIncreasing() const; Thank you
