  • Is there an HTML browser rendering engine for Ruby?

    - by Jose
    Given a URL, I would like to be able to render the returned HTML to know width and height for each div, fonts' size for each piece of text, color of each element, position of each element on screen, etc. A possible approach could be traversing the DOM tree with Hpricot and checking CSS style by parsing the associated stylesheet using css_parser gem. But this would not consider default styles, inheritance, floats, etc. In Java there's Cobra, a Java Web Renderer, which is able to render a web page and query attributes like width, font size, etc. for each fragment. I could use Cobra with JRuby or similar solutions, but prefer a Ruby native tool. Is there any library like this for Ruby?

  • What exactly are tuples in Python?

    - by Sergio Tapia
    I'm following a couple of Pythone exercises and I'm stumped at this one. # C. sort_last # Given a list of non-empty tuples, return a list sorted in increasing # order by the last element in each tuple. # e.g. [(1, 7), (1, 3), (3, 4, 5), (2, 2)] yields # [(2, 2), (1, 3), (3, 4, 5), (1, 7)] # Hint: use a custom key= function to extract the last element form each tuple. def sort_last(tuples): # +++your code here+++ return What is a Tuple? Do they mean a List of Lists?

  • Establish draggable content constraints depending on position

    - by drukelly
    Asking all jQuery experts! How would I go about setting up constraints for a draggable element depending on its positioning? I have a basic example here. I thought it would be as simple as adding an option, containment. Ideally, I want it to drag within the following box: top: 0px left: 0px top: -263px left: -272px top: 0px left: -272px top: -263px left: 0px Is there a way to drag the element within the parameters above so you don't the extra white space? I appreciate the help!

  • Issue parsing RSS xml

    - by cw
    Hello, I'm having an issue using Linq to XML parsing the following XML. What I am doing is getting the element checking if it's what I want, then moving to the next. I am pretty sure it has to do with the xmlns, but I need this code to work with both this style and normal style RSS feeds (no xmlns). Any ideas? <?xml version="1.0" encoding="UTF-8"?> <rdf:RDF xmlns:rdf="http://someurl" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/"> <channel rdf:about="http://someurl"> XElement currentLocation = startElementParameter; foreach (string x in ("channel\\Title").Split('\\')) { if (condition1 == false) { continue; } else if (condition2 == false) { break; } else { // This is returning null. currentLocation = currentLocation.Element(x); } } Thanks!

  • Jquery UI Sortable - Get the item being sorted.

    - by Smickie
    Hi, When using Jquery UI Sortable (which is great by the way) how do you get the item that is currently being sorted. When you use $(this); it return the actual sortable list, not the current sorted item. I want to do fancy-pants things with the widget when the user is dragging it around. E.g. Animate it when dragging between two lists. So how do I get the current item being sorted? There a little code below just to explain a little more... $(function() { $("#sortable_1").sortable({ start : function(event, ui){ //get current element being sorted }, stop : function(event, ui){ //get current element being sorted } }).disableSelection(); });

  • Cannot add namespace prefix to children using XSL

    - by Erdal
    I checked many answers here and I think I am almost there. One thing that is bugging me (and for some reason my peer needs it) follows: I have the following input XML: <?xml version="1.0" encoding="utf-8"?> <MyRoot> <MyRequest CompletionCode="0" CustomerID="9999999999"/> <List TotalList="1"> <Order CustomerID="999999999" OrderNo="0000000001" Status="Shipped"> <BillToAddress ZipCode="22221"/> <ShipToAddress ZipCode="22222"/> <Totals Tax="0.50" SubTotal="10.00" Shipping="4.95"/> </Order> </List> <Errors/> </MyRoot> I was asked to produce this: <ns:MyNewRoot xmlns:ns="http://schemas.foo.com/response" xmlns:N1="http://schemas.foo.com/request" xmlns:N2="http://schemas.foo.com/details"> <N1:MyRequest CompletionCode="0" CustomerID="9999999999"/> <ns:List TotalList="1"> <N2:Order CustomerID="999999999" Level="Preferred" Status="Shipped"> <N2:BillToAddress ZipCode="22221"/> <N2:ShipToAddress ZipCode="22222"/> <N2:Totals Tax="0.50" SubTotal="10.00" Shipping="4.95"/> </N2:Order> </ns:List> <ns:Errors/> </ns:MyNewRoot> Note the children of the N2:Order also needs N2: prefix as well as the ns: prefix for the rest of the elements. I use the XSL transformation below: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:template match="@* | node()"> <xsl:copy> <xsl:apply-templates select="@* | node()"/> </xsl:copy> </xsl:template> <xsl:template match="/MyRoot"> <MyNewRoot xmlns="http://schemas.foo.com/response" xmlns:N1="http://schemas.foo.com/request" xmlns:N2="http://schemas.foo.com/details"> <xsl:apply-templates/> </MyNewRoot> </xsl:template> <xsl:template match="/MyRoot/MyRequest"> <xsl:element name="N1:{name()}" namespace="http://schemas.foo.com/request"> <xsl:copy-of select="namespace::*"/> <xsl:apply-templates select="@* | node()"/> </xsl:element> </xsl:template> <xsl:template match="/MyRoot/List/Order"> <xsl:element name="N2:{name()}" namespace="http://schemas.foo.com/details"> <xsl:copy-of select="namespace::*"/> <xsl:apply-templates select="@* | node()"/> </xsl:element> </xsl:template> </xsl:stylesheet> This one doesn't process the ns (I couldn't figure this out). When I process thru the above the XSL transformation with AltovaXML I end up with below: <MyNewRoot xmlns="http://schemas.foo.com/response" xmlns:N1="http://schemas.foo.com/request" xmlns:N2="http://schemas.foo.com/details"> <N1:MyRequest CompletionCode="0" CustomerID="9999999999"/> <List xmlns="" TotalList="1"> <N2:Order CustomerID="999999999" Level="Preferred" Status="Shipped"> <BillToAddress ZipCode="22221"/> <ShipToAddress ZipCode="22222"/> <Totals Tax="0.50" SubTotal="10.00" Shipping="4.95"/> </N2:Order> </List> <Errors/> </MyNewRoot> Note that N2: prefix for the children of Order is not there after the XSL transformation. Also additional xmlns="" in the Order header (for some reason). I couldn't figure out putting the ns: prefix for the rest of the elements (like Errors and List). First of all, why would I need to put the prefix for the children if the parent already has it. Doesn't the parent namespace dictate the children nodes/attribute namespaces? Secondly, I want to add the prefixes in the above XML as expected, how can I do that with XSL?

  • How to incorporate WebSockets into a Cocoa application

    - by robw
    I am developing a Cocoa application which involves a chat element. One approach I've considered is using Websockets to handle client-server communication. This would be particularly desirable because chats will also be displayed on a website, and using Websockets could make the implementation very simple. So: would it be possible to use a WebView element, and use Websockets within it? (I know Safari doesn't support Websockets yet, so I imagine this is not possible?) Failing that, are there any Websocket client libraries for C, Objective C, or any other language I could successfully embed within my application? Suggestions welcomed.

    - by Harish Kurup
    I am using Symfony PHP Framework to create web application, and using symfony Forms to create the HTML forms. I am trying to load the data in Select element using Ajax, for that i am using jQuery's Ajax functions. It is working fine as it sends and gets the response correctly(status as 200), but not calling the Callback function in some browsers such as IE,Chrome and Safari.It works fine in Firefox and Opera. the Code that is not working, $.ajax({ type: 'POST', url: 'form/ajax', async: true, cache: false, dataType : 'json', data: 'id='+ids, success: function(jsonData){ alert("ok go"); } }); the alert "OK Go" is not called in Chrome,IE and Safari But $.ajax({ type: 'POST', url: 'form/ajax', async: true, cache: false, dataType : 'json', data: 'id='+ids, success: alert("ok go"); }); this works, but as per the project i want the JSON data to load in my Select element. is there any thing wrong in the return JSON format or the bug in the jQuery Ajax functions, please help.

  • How to determine whether a dependency object implements a given dependency property (C# / WPF)

    - by Tim Coulter
    I am working with the classes in the System.Windows.Documents namespace, trying to write some generic code that will conditionally set the value of certain dependency properties, depending on whether these properties exist on a given class. For example, the following method assigns an arbitrary value to the Padding property of the passed FrameworkContentElement: void SetElementPadding(FrameworkContentElement element) { element.SetValue(Block.PaddingProperty, new Thickness(155d)); } However, not all concrete implementations of FrameworkContentElement have a Padding property (Paragraph does but Span does not) so I would expect the property assignment to succeed for types that implement this property and to be silently ignored for types that do not. But it seems that the above property assignment succeeds for instances of all derivatives of FrameworkContentElement, regardless of whether they implement the Padding property. I make this assumption because I have always been able to read back the assigned value. I assume there is some flaw in the way I am assigning property values. What should I do to ensure that a given dependency property assignment is ignored by classes that do not implement that property? Many thanks for your advice. Tim

  • Office Communicator Auto Accept Calls with C# API

    - by Dennis
    Is there a way to automatically accept calls programmed with the C# Api when someone calls 'me' to start a video call? Starting a video call with the API is easy: var contactArray = new ArrayList(); contactArray.Add("[email protected]"); object[] sipUris = new object[contactArray.Count]; int currentObject = 0; foreach (object contactObject in contactArray) { sipUris[currentObject] = contactObject; currentObject++; } var communicator = new Messenger(); communicator.OnIMWindowCreated += new DMessengerEvents_OnIMWindowCreatedEventHandler(communicator_OnIMWindowCreated); IMessengerAdvanced msgrAdv = communicator as CommunicatorAPI.IMessengerAdvanced; if (msgrAdv != null) { try { object obj = msgrAdv.StartConversation(CommunicatorAPI.CONVERSATION_TYPE.CONVERSATION_TYPE_VIDEO, sipUris, null, "Conference Wall CZ - Conversation", "1", null); } catch (COMException ex) { Console.WriteLine(ex.Message); } } But on the other side i want to automatically accept this call....

  • XPath to find ancestor node containing CSS class

    - by Juan Mendes
    I am writing some Selenium tests and I need to be able to find an ancestor of a WebElement that I have already found. This is what I'm trying but is returning no results // checkbox is also a WebElement WebElement container = checkbox.findElement(By.xpath( "current()/ancestor-or-self::div[contains(@class, 'x-grid-view')]") ); The image below shows the div that I have selected highlighted in dark blue and the one I want to find with an arrow pointing at it.

  • XmlDocument from LINQ to XML query

    - by Ben
    I am loading an XML document into an XDocument object, doing a query and then returning the data through a web service as an XmlDocument object. The code below works fine, but it just seems a bit smelly. Is there a cleaner way to take the results of the query and convert back to an XDocument or XmlDocument? XDocument xd = XDocument.Load(Server.MapPath(accountsXml)); var accounts = from x in xd.Descendants("AccountsData") where userAccounts.Contains(x.Element("ACCOUNT_REFERENCE").Value) select x; XDocument xd2 = new XDocument( new XDeclaration("1.0", "UTF-8", "yes"), new XElement("Accounts") ); foreach (var account in accounts) xd2.Element("Accounts").Add(account); return xd2.ToXmlDocument();

  • Listening and firing events with Javascript and maybe jQuery

    - by at
    In my Javascript and Flex applications, users often perform actions that I want other Javascript code on the page to listen for. For example, if someone adds a friend. I want my Javascript app to then call something like triggerEvent("addedFriend", name);. Then any other code that was listening for the "addedFriend" event will get called along with the name. Is there a built-in Javascript mechanism for handling events? I'm ok with using jQuery for this too and I know jQuery makes extensive use of events. But with jQuery, it seems that its event mechanism is all based around elements. As I understand, you have to tie a custom event to an element. I guess I can do that to a dummy element, but my need has nothing to do with DOM elements on a webpage. Should I just implement this event mechanism myself?

  • Build XML document using Linq To XML

    - by JasonDR
    Given the following code: string xml = ""; //alternativley: string xml = "<people />"; XDocument xDoc = null; if (!string.IsNullOrEmpty(xml)) { xDoc = XDocument.Parse(xml); xDoc.Element("people").Add( new XElement("person", "p 1") ); } else { xDoc = new XDocument(); xDoc.Add(new XElement("people", new XElement("person", "p 1") )); } As you can see, if the xml variable is blank, I need to create the rood node manually, and append the person the root node, whereas if it is not, I simple add to the people element My question is, is there any way to generically create the document, where it will add all referenced node automatically if they do not already exists?

  • Moving from Linear Probing to Quadratic Probing (hash collisons)

    - by Nazgulled
    Hi, My current implementation of an Hash Table is using Linear Probing and now I want to move to Quadratic Probing (and later to chaining and maybe double hashing too). I've read a few articles, tutorials, wikipedia, etc... But I still don't know exactly what I should do. Linear Probing, basically, has a step of 1 and that's easy to do. When searching, inserting or removing an element from the Hash Table, I need to calculate an hash and for that I do this: index = hash_function(key) % table_size; Then, while searching, inserting or removing I loop through the table until I find a free bucket, like this: do { if(/* CHECK IF IT'S THE ELEMENT WE WANT */) { // FOUND ELEMENT return; } else { index = (index + 1) % table_size; } while(/* LOOP UNTIL IT'S NECESSARY */); As for Quadratic Probing, I think what I need to do is change how the "index" step size is calculated but that's what I don't understand how I should do it. I've seen various pieces of code, and all of them are somewhat different. Also, I've seen some implementations of Quadratic Probing where the hash function is changed to accommodated that (but not all of them). Is that change really needed or can I avoid modifying the hash function and still use Quadratic Probing? EDIT: After reading everything pointed out by Eli Bendersky below I think I got the general idea. Here's part of the code at http://eternallyconfuzzled.com/tuts/datastructures/jsw_tut_hashtable.aspx: 15 for ( step = 1; table->table[h] != EMPTY; step++ ) { 16 if ( compare ( key, table->table[h] ) == 0 ) 17 return 1; 18 19 /* Move forward by quadratically, wrap if necessary */ 20 h = ( h + ( step * step - step ) / 2 ) % table->size; 21 } There's 2 things I don't get... They say that quadratic probing is usually done using c(i)=i^2. However, in the code above, it's doing something more like c(i)=(i^2-i)/2 I was ready to implement this on my code but I would simply do: index = (index + (index^index)) % table_size; ...and not: index = (index + (index^index - index)/2) % table_size; If anything, I would do: index = (index + (index^index)/2) % table_size; ...cause I've seen other code examples diving by two. Although I don't understand why... 1) Why is it subtracting the step? 2) Why is it diving it by 2?

  • Trying to integrate Jeditable+MarkItUp and Thickbox/Lightbox

    - by Bob Sawyer
    I've managed to successfully integrate MarkItUp with Jeditable based on the instructions on those two sites. What I would really like to do, however, is to have the Jeditable/MarkItUp editing window appear in a Thickbox or Lightbox overlay. So far my attempts to do this have not been successful. So, at the moment, I have the standard code: $.editable.addInputType('markitup', { element : $.editable.types.textarea.element, plugin : function(settings, original) { $('textarea', this).markItUp(settings.markitup); } }); $(".editme").editable("/content/save", { event : 'dblclick', type : 'markitup', submit : 'OK', cancel : 'Cancel', width : 640, height : 'auto', tooltip : 'Double-click to edit...', onblur : 'ignore', markitup : mySettings }); I've found other posts here that show how to trigger the edit box by clicking on a link rather than the object itself, and I've tried integrating that with the Thickbox calls, to no avail. Would appreciate anyone pointing me in the right direction. Thanks!

  • address representation in ada

    - by maddy
    Hi all, I have pasted a code below which is in ada language.I need some clarification on some implementations. C : character; Char : character; type Myarr_Type is array (character range 'A'..'K') of character; Myarr : Myarr_Type := ('A','B','C','D','E','F','G','H','I','J','K'); Next_Address := Myarr'address Last_Address := Next_Address + Storage_Offset'(40); my_func(int P1,int P2) { return P2 + Storage_Offset'(4); } Last_Address := Next_Address + Storage_Offset'(4); Now my doubt is 1)what does P2 + Storage_Offset'(4) actually mean.Does that mean that its returning the address of the next element in the array which is 'B'.Storage_Offset'(4) in ada --does this mean 4 bits or 4 bytes of memory. 2) If i assume that Last_Address points to last element of the array which is 'K',how does the arithmentic Storage_Offset'(40) satisfies the actual implementation? Please get back to me if u need any more clarifications. Thanks Maddy

  • What is the best software to capture full-screen 3h programming session in Windows?

    - by Hugo S Ferreira
    Hi, I'm planning a laboratorial experiment to assess behavior of groups when programming using some tools under study. For that, I'll need to capture their entire screen to disk. Mostly, what will be displayed is code, so I'm not to worried with image quality. However, it's paramount that the team is not able to stop the recording by accident, and the tool should be rebust enough to hold at least 3h of video. If possible, it would be nice for researchers in other rooms to "watch" the video as it is recording. Actually, this last requirement reminded me that I could use a VNC recording software, and install a VNC client in each laboratory computer. Anyway, what is your experience with this? Which software do you recommend? Thanks.

  • Java dropping half of UDP packets

    - by Andrew Klofas
    Greetings, I have a simple client/server setup. The server is in C and the client that is querying the server is Java. My problem is that, when I send bandwidth-intensive data over the connection, such as Video frames, it drops up to half the packets. I make sure that I properly fragment the udp packets on the server side (udp has a max payload length of 2^16). I verified that the server is sending the packets (printf the result of sendto()). But java doesn't seem to be getting half the data. Furthermore, when I switch to TCP, all the video frames get through but the latency starts to build up, adding several seconds delay after a few seconds of runtime. Is there anything obvious that I'm missing? I just can't seem to figure this out. Thanks, Andrew

  • Are there any real benefits to including javascript dynamically rather than as script tags at the bo

    - by SB
    I've read that including the scripts dynamically may provide some better performance, however i'm not really seeing that on the small local tests I'm doing. I created a jquery plugin to dynamically load other plugins as necessary and am curious as to if this is actually a good idea. The following would be called onready or at the bottom of the page(I can provide the source for the plugin if anyone is interested): $.fn.executePlugin( 'qtip', // looks in default folder { required: '/javascript/plugin/easing.js', // not really required for qtip just testing it version: 1, //used for versioning and caching checkelement: '#thumbnail', // will not include plugin if $(element).length==0 css: 'page.css', // include this css file as well with plugin cache:true, // $.ajax will use cache:true success:function() { // success function to be called after the plugin loads - apply qtip to an element $('#thumbnail').qtip( { content: 'Some basic content for the tooltip', // Give it some content, in this case a simple string style: {name:'cream'}, }); } });

  • Testing MPMoviePlayerViewController in iPad simulator

    - by hgpc
    I have a view that shows a MPMoviePlayerViewController modally. When testing it in the iPad simulator it works well on the first try. If I dismiss the video and then show the view again, the player only plays the audio, but not the video. Is this a simulator quirk or am I doing something wrong? Here's my code: - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; MPMoviePlayerViewController* v = [[MPMoviePlayerViewController alloc] initWithContentURL:url]; [[NSNotificationCenter defaultCenter] addObserver:self selector: @selector(playbackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:v.moviePlayer]; [self presentMoviePlayerViewControllerAnimated:v]; [v release]; } -(void) playbackDidFinish:(NSNotification*)aNotification { MPMoviePlayerController *player = [aNotification object]; [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:player]; [player stop]; [self dismissMoviePlayerViewControllerAnimated]; }
