  • Enumerate registered namespaces of a PHP DOMDocument object

    - by zneak
    Hello world, For one of my projects, I'm using the DOMDocument class to load and manipulate XML documents. I'd need to retrieve every namespace used in the document; however, I can't find how I'd do that. The DOMDocument class has methods to get the namespace prefix of an URI or the URI of a namespace prefix, but I've seen nothing to actually enumerate registered namespaces. The SimpleXML library has a getNamespaces() method for that. Is there an equivalent for DOMDocument?

  • Linq query with aggregate function OrderBy

    - by Billy Logan
    Hello everyone, I have the following LinqToEntities query, but am unsure of where or how to add the orderby clause: var results = from d in db.TBLDESIGNER join s in db.TBLDESIGN on d.ID equals s.TBLDESIGNER.ID where s.COMPLETED && d.ACTIVE let value = new { s, d} let key = new { d.ID, d.FIRST_NAME, d.LAST_NAME } group value by key into g orderby g.Key.FIRST_NAME ascending, g.Key.LAST_NAME ascending select new { ID = g.Key.ID, FirstName = g.Key.FIRST_NAME, LastName = g.Key.LAST_NAME, Count = g.Count() }; This should be sorted by First_Name ascending and then Last_Name ascending. I have tried adding ordering but It has had no effect on the result set. Could someone please provide an example of where the orderby would go assuming the query above. Thanks, Billy

  • Execute a function when a <link> element has finished loading

    - by nornagon
    I'm using jQuery Masonry to lay out my page, but I'm using a custom @font-face font. The problem being that Masonry doesn't know the metrics of the font until it's loaded. The Masonry docs suggest that you use $(window).load() instead of $(document).ready() to call the layout functions, but I don't want to have to wait until all the images etc. load. I can specify the dimensions of the images exactly, so Masonry doesn't need to wait until they're loaded. It's just the text that's the problem. How can I get jQuery to call a callback when the <link> element that links in the font finishes loading?

    - by Diver Dan
    I have a webapi project running rc I have a very basic controlller like [System.Web.Http.HttpPost] public void Update(Business business) { //if (business.Id == Guid.Empty) //{ // throw new HttpResponseException("Business ID not provided", HttpStatusCode.BadRequest); //} _repository.Update(business); //if (!isUpdated) //{ // throw new HttpResponseException("Business not found", HttpStatusCode.NotFound); //} } I found an example using HttpClient however it doesnt work with rc using (var client = new HttpClient()) { try { string url = string.Format("{0}{1}", ConfigurationManager.AppSettings["ApiBaseUrl"].ToString(),apiMethod); HttpRequestMessage request = new HttpRequestMessage(); MediaTypeFormatter[] formatter = new MediaTypeFormatter[] { new JsonMediaTypeFormatter() }; var content = request.CreateContent<Business>( business, MediaTypeHeaderValue.Parse("application/json"), formatter, new FormatterSelector()); HttpResponseMessage response = client.PostAsync(url, content).Result; return response.Content.ToString(); } catch (Exception ex) { return null; } } I get an error Method not found: 'Void System.Net.Http.Headers.HttpHeaders.AddWithoutValidation(System.String, System.String)'. Passing the data from jquery is a piece of cake however I need call the api from code behind vs client side. Can someone point me in the right direction for calling the webapi? Thank you

  • iTunes Visualizer Plugin in C# - Energy Function

    - by James D
    Hi, iTunes Visualizer plugin in C#. Easiest way to compute the "energy level" for a particular sample? I looked at this writeup on beat detection over at GameDev and have had some success with it (I'm not doing beat detection per se, but it's relevant). But ultimately I'm looking for a stupid-as-possible, quick-and-dirty approach for demo purposes. For those who aren't familiar with how iTunes structures visualization data, basically you're given this: struct VisualPluginData { /* SNIP */ RenderVisualData renderData; UInt32 renderTimeStampID; UInt8 minLevel[kVisualMaxDataChannels]; // 0-128 UInt8 maxLevel[kVisualMaxDataChannels]; // 0-128 }; struct RenderVisualData { UInt8 numWaveformChannels; UInt8 waveformData[kVisualMaxDataChannels][kVisualNumWaveformEntries]; // 512-point FFT UInt8 numSpectrumChannels; UInt8 spectrumData[kVisualMaxDataChannels][kVisualNumSpectrumEntries]; }; Ideally, I'd like an approach that a beginning programmer with little to no DSP experience could grasp and improve on. Any ideas? Thanks!

  • referencing an instantiated object in another class in objective C

    - by Paul
    hi, I am working in xcode on an ipod app in objective C, and I have a field (navigationController) in one of my classes (rootViewController). How do I reference the instantiated rootViewController's navigationController from another class? For example, how would I do this if I want to reference the navigationController from the FirstViewController.m class? I seem to only be able to find references for this to reference the application delegate. If I want to reference the application delegate with FirstViewController, I just say: MyAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [delegate.navigationController pushViewController:childController animated:YES]; how do I do this for the rootViewController class instead of MyAppDelegate?

  • Resharper function to fix naming convention issues

    - by Jan Jongboom
    A bunch of classes doesn't comply to our naming conventions for private variables. Resharper shows this as a warning, but wants me to fix all of them by hand. Is there some magic option to auto-fix these issues? 'Clean-up code' won't do anything with this. Same goes for converting properties with backing fields to automatic properties when possible: the hint is shown, but Resharper won't fix it automatically.

  • Javascript Object/Array population question

    - by gnomixa
    Is there a difference between: var samples = { "TB10152254-001": { folderno: "TB10152254", ordno: "001", startfootage: "", endfootage: "", tagout: "Y" }, "TB10152254-002": { folderno: "TB10152254", ordno: "002", startfootage: "", endfootage: "", tagout: "Y" }, "TB10152254-003": { folderno: "TB10152254", ordno: "003", startfootage: "", endfootage: "", tagout: "Y" } }; AND var samples = new Array(); samples["TB10152254-001"] = { folderno: "TB10152254", ordno: "001", startfootage: "", endfootage: "", tagout: "Y"}; samples["TB10152254-002"] = { folderno: "TB10152254", ordno: "002", startfootage: "", endfootage: "", tagout: "Y" }; samples["TB10152254-003"] = { folderno: "TB10152254", ordno: "003", startfootage: "", endfootage: "", tagout: "Y" }; EDIT: I will re-phrase the question: How do I populate the hash dynamically? I can't do something like samples.TB10152254-003 because i TB10152254-003 is dynamic...so, is that even possible?

  • SHA function issues

    - by Damian James
    I have this php code from my login.php if (isset($_POST['logIn'])) { $errmsg = ""; $logname = mysqli_real_escape_string($dbc, trim($_POST['usernameIn'])); $logpassword = mysqli_real_escape_string($dbc, trim($_POST['passwordIn'])); $query = "SELECT user_id, username FROM members WHERE username = '$logname' AND password = SHA('$logpassword')"; $data = mysqli_query($dbc, $query); if (mysqli_num_rows($data) == 1) { $row = mysqli_fetch_array($data); setcookie('user_id', $row['user_id'], time() + (60 * 60 * 24 * 30)); //expires after 30 days setcookie('username', $row['username'], time() + (60 * 60 * 24 * 30)); $home = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/index.php'; header('Location: ' . $home); } else { $errmsg = '<p class="errormsg">Username or password is incorrect.</p>'; } } And for some reason, it always ends up setting $errmsg in the else statement. I am sure that I'm entering information (username,password) that is correct and exists in the database. I insert my values (from a signup script) using this query: $query = "INSERT INTO members (username, password, email) VALUES ('$username', SHA('$password'), '$email')"; Anyone see the problem with this script? Thanks!

  • Spring @PostConstruct function in a @Repository called multiple times

    - by Seth
    I have a DAO that I'm trying to inject into a couple different places: @Repository public class FooDAO { @Autowired private HibernateManager sessionFactory; @PostConstruct public void doSomeDatabaseStuff() throws DataAccessException { ... } } And my application-context.xml is a fairly simple context:component-scan: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd" default-init-method="init" default-destroy-method="destroy"> <context:component-scan base-package="top.level"/> </beans> The DAO is accessed from a couple servlets in my application server through @Autowired properties. As far as I understand, anything annotated with @Repository should default to being a singleton and thus doSomeDatabaseStuff() should only be called once (as is my intention). The problem is that I'm seeing doSomeDatabaseStuff() called multiple times. What's going on here? Have I set something up incorrectly? I'm using spring 3.0.0. Thanks for the help.

  • How to generate function call graphs for JavaScript?

    - by Jeremy Rudd
    Are there softwares that can generate graphs that show which functions call which functions? I need to analyze JavaScript source code, a language which Doxygen/Graphviz does not support, though it does support C++ and others. If there are no tools that support JavaScript out-of-the-box, is there a way to convert JS to C++ so I can use Doxygen itself?

  • PHP gettext function only returns orignal untranslated string

    - by Camsoft
    I'm trying to use gettext add localisation support to my website. I've followed various guides on how to setup gettext and have done the following: I've created the following files and directories in the root of my project dir: test.php locale/ de_DE LC_MESSAGES messages.mo messages.po en_GB LC_MESSAGES messages.mo messages.po I've used Poedit to create the above .po and mo files. I've made sue it use Unix line endings, UTF-8 and set the language and country accordingly. I've then created a PHP script called test.php which has the following code: <?php define('LOCALE', 'de_DE'); // Set up environmental variables putenv("LC_ALL=" . LOCALE); setlocale(LC_ALL, LOCALE); bindtextdomain("messages", "./locale"); bind_textdomain_codeset("messages", LOCALE .".utf8"); textdomain("messages"); die(gettext('This is a test.')); ?> I've imported the text "This is a test." to Poedit and supplied the translation and saved it. But for some reason the test.php script will only output the original text untranslated. It refuses to load the version for the translation files. It's worth noting that the server is running Linux (Ubuntu), Apache 2.2.11 and PHP 5.2.6-3ubuntu4.5. I've checked phpinfo() and gettext is enabled. Can someone help me? Thanks.

  • Django shows too many warnings when deleting an object

    - by valya
    Hello! I have two models: class Account(models.Model): main_request = models.ForeignKey('JournalistRequest', related_name='main_request') key = models.CharField(_('Key'), max_length=100) class JournalistRequest(models.Model): account = models.ForeignKey(Account, blank=True, null=True) When I try to delete a JournalistRequest, It shows warning with a lot of nesting, like Are you sure you want to delete the selected ?????? ??? objects? All of the following objects and their related items will be deleted: Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request All accounts are the same one (ids are same), and all requests are the same one, so I think it becaues of a recursion. But I have no idea how to solve this problem in Django 1.1.1! Can you help me?

  • Applying the same function to each object of an array in objective-c

    - by sagar
    Hey ! every one. I am having some query regarding Objective-c. Let's have a look to following code. NSArray *ar=[scrPDFPage subviews]; int i; for (i=0; i<[ar count]; i++) { [(UIView*)[ar objectAtIndex:i] removeFromSuperview]; } now my queries are as follows, Instead of rotating a loop, isn't there an option like, [ar applyFunctionToObjects:@selector(myFunction:)] Isn't there any option like [myView removeAllSubViews]; ( According to my knowledge, there is no option like remove all sub views, but in case you might know. ) Thanks in advance for sharing your knowledge.

  • Proving that a function f(n) belongs to a Big-Theta(g(n))

    - by PLS
    Its a exercise that ask to indicate the class Big-Theta(g(n)) the functions belongs to and to prove the assertion. In this case f(n) = (n^2+1)^10 By definition f(n) E Big-Theta(g(n)) <= c1*g(n) < f(n) < c2*g(n), where c1 and c2 are two constants. I know that for this specific f(n) the Big-Theta is g(n^20) but I don't know who to prove it properly. I guess I need to manipulate this inequality but I don't know how
