  • How to use webbrowser control DocumentCompleted event in C# ?

    - by Margus
    Before starting writing this question, i was trying to solve following // 1. navigate to page // 2. wait until page is downloaded // 3. read and write some data from/to iframe // 4. submit (post) form The problem was, that if a iframe exists on a web page, DocumentCompleted event would get fired more then once (after each document has been completed). It was highly likely that program would have tried to read data from DOM that was not completed and naturally - fail. But suddenly while writing this question 'What if' monster inspired me, and i fix'ed the problem, that i was trying to solve. As i failed Google'ing this, i thought it would be nice to post it here. private int iframe_counter = 1; // needs to be 1, to pass DCF test public bool isLazyMan = default(bool); /// <summary> /// LOCK to stop inspecting DOM before DCF /// </summary> public void waitPolice() { while (isLazyMan) Application.DoEvents(); } private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e) { if(!e.TargetFrameName.Equals("")) iframe_counter --; isLazyMan = true; } private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { if (!((WebBrowser)sender).Document.Url.Equals(e.Url)) iframe_counter++; if (((WebBrowser)sender).Document.Window.Frames.Count <= iframe_counter) {//DCF test DocumentCompletedFully((WebBrowser)sender,e); isLazyMan = false; } } private void DocumentCompletedFully(WebBrowser sender, WebBrowserDocumentCompletedEventArgs e){ //code here } For now at least, my 5m hack seems to be working fine. Maybe i am really failing at querying google or MSDN, but i can not find: "How to use webbrowser control DocumentCompleted event in C# ?"

Great, now try this <p:commandLink value="Tom" onclick="document.getElementById('tom').focus()"/><br/> <h:inputText id="tom"/> <br/> when I click nothing happen, I check firebug, I see document.getElementById("tom") is null When I try to use jQuery $('#tom').focus(), nothing happen, no error, but did not get focus either.

  • problems with scrolling a java TextArea

    - by Jonathan
    All, I am running into an issue using JTextArea and JScrollPane. For some reason the scroll pane appears to not recognize the last line in the document, and will only scroll down to the line before it. The scroll bar does not even change to a state where I can slide it until the lines in the document are two greater than the number of lines the textArea shows (it should happen as soon as it is one greater). Has anyone run into this before? What would be a good solution (I want to avoid having to add an extra 'blank' line to the end of the document, which I would have to remove every time I add a new line)? Here is how I instantiate the TextArea and ScrollPane: JFrame frame = new JFrame("Java Chat Program"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Container pane = frame.getContentPane(); if (!(pane.getLayout() instanceof BorderLayout)) { System.err.println("Error: UI Container does not implement BorderLayout."); System.exit(-1); } textArea = new JTextArea(); textArea.setPreferredSize(new Dimension(500, 100)); textArea.setEditable(false); textArea.setLineWrap(true); textArea.setWrapStyleWord(true); JScrollPane scroller = new JScrollPane(textArea); scroller.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS); pane.add(scroller, BorderLayout.CENTER); Here is the method I use to add a new line to textArea: public void println(String a) { textArea.append(" "+a+"\n"); textArea.setCaretPosition(textArea.getDocument().getLength()); } Thanks for your help, Jonathan EDIT: Also, as a side note, with the current code I have to manually scroll down. I assumed that setCaretPosition(doc.getLength()) in the println(line) method would automatically set the page to the bottom after a line is entered... Should that be the case, or do I need to do something differently?

  • Facebook multi-friend-selector + new javascript API = BROKEN ?

    - by Simon_Weaver
    I am using the fb:serverfbml tag to render a multi-friend-selector inside an IFrame. I am using the new javascript API. I have been trying ALL DAY to get it working. When I click on the underlines 'selected' link (to filter by the selected friends) the whole page refreshes and the selected friends disappear. Does the multi-friend-selector just not work with the javascript API? <fb:serverfbml> <script type="text/fbml"> <fb:request-form action="http://apps.facebook.com/rollingrazor/" target="_top" method="POST" invite="true" type="Blah blah blah" content="Blah blah! &lt;fb:req-choice url=&quot;http://apps.facebook.com/rollingrazor/&quot; label=&quot;Let me check my friends&quot; /&gt;"> <fb:multi-friend-selector showborder="false" actiontext="Invite your friends" rows="5" cols="5" bypass="cancel" target="_top" /> </fb:request-form> </script> </fb:serverfbml> <div id="fb-root"></div> <script> window.fbAsyncInit = function () { FB.init({ appId: 'xxxxxxx', status: true, cookie: true, xfbml: true }); }; (function () { var e = document.createElement('script'); e.async = true; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; document.getElementById('fb-root').appendChild(e); } ()); </script> Can someone give me a working example using new javascript API with a multi-friend-selector?

  • Distinguishing between .NET exception types

    - by Swingline Rage
    For the love of all things holy, how do you distinguish between different "exception flavors" within the predefined .NET exception classes? For example, a piece of code might throw an XmlException under the following conditions: The root element of the document is NULL Invalid chars are in the document The document is too long All of these are thrown as XmlException objects and all of the internal "tell me more about this exception" fields (such as Exception.HResult, Exception.Data, etc.) are usually empty or null. That leaves Exception.Message as the only thing that allows you to distinguish among these exception types, and you can't really depend on it because, you guessed it, the Exception.Message string is glocabilized, and can change when the culture changes. At least that's my read on the documentation. Exception.HResult and Exception.Data are widely ignored across the .NET libraries. They are the red-headed stepchildren of the world's .NET error-handling code. And even assuming they weren't, the HRESULT type is still the worst, downright nastiest error code in the history of error codes. Why we are still looking at HRESULTs in 2010 is beyond me. I mean if you're doing Interop or P/Invoke that's one thing but... HRESULTs have no place in System.Exception. HRESULTs are a wart on the proboscis of System.Exception. But seriously, it means I have to set up a lot of detailed specific error-handling code in order to figure out the same information that should have been passed as part of the exception data. Exceptions are useless if they force you to work like this. What am I doing wrong?

  • error C2504: 'BASECLASS' : base class undefined

    - by numerical25
    I checked out a post similar to this but the linkage was different the issue was never resolved. The problem with mine is that for some reason the linker is expecting there to be a definition for the base class, but the base class is just a interface. Below is the error in it's entirety c:\users\numerical25\desktop\intro todirectx\godfiles\gxrendermanager\gxrendermanager\gxrendermanager\gxdx.h(2) : error C2504: 'GXRenderer' : base class undefined Below is the code that shows how the headers link with one another GXRenderManager.h #ifndef GXRM #define GXRM #include <windows.h> #include "GXRenderer.h" #include "GXDX.h" #include "GXGL.h" enum GXDEVICE { DIRECTX, OPENGL }; class GXRenderManager { public: static int Ignite(GXDEVICE); private: static GXRenderer *renderDevice; }; #endif at the top of GxRenderManager, there is GXRenderer , windows, GXDX, GXGL headers. I am assuming by including them all in this document. they all link to one another as if they were all in the same document. correct me if I am wrong cause that's how a view headers. Moving on... GXRenderer.h class GXRenderer { public: virtual void Render() = 0; virtual void StartUp() = 0; }; GXGL.h class GXGL: public GXRenderer { public: void Render(); void StartUp(); }; GXDX.h class GXDX: public GXRenderer { public: void Render(); void StartUp(); }; GXGL.cpp and GXDX.cpp respectively #include "GXGL.h" void GXGL::Render() { } void GXGL::StartUp() { } //...Next document #include "GXDX.h" void GXDX::Render() { } void GXDX::StartUp() { } Not sure whats going on. I think its how I am linking the documents, I am not sure.

  • Create Hello World with RESTful web service and Jersey

    - by Harry Pham
    I follow tutorial here on how to create web service using RESTful web service and Jersey and I get kind of stuck. The code is from HelloWorld3 in the tutorial I linked above. Here is the code. I use Netbean6.8 + glassfish v3 RESTGreeting.java create using JAXB. This class represents the HTML message in Java package com.sun.rest; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlElement; @XmlRootElement(name = "restgreeting") public class RESTGreeting { private String message; private String name; /** * Creates new instance of Greeting */ public RESTGreeting() { } /* Create new instance of Greeting * with parameters message and name */ public RESTGreeting( String message, String name) { this.message = message; this.name = name; } /** Getter for message * return value for message * */ @XmlElement public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } /* Getter for name * return name */ @XmlElement public String getName() { return name; } public void setName(String name) { this.name = name; } } HelloGreetingService.java creates a RESTful web service that returns an HTML message package com.sun.rest; import javax.ws.rs.core.Context; import javax.ws.rs.core.UriInfo; import javax.ws.rs.Consumes; import javax.ws.rs.PUT; import javax.ws.rs.Path; import javax.ws.rs.GET; import javax.ws.rs.Produces; import javax.ws.rs.QueryParam; @Path("helloGreeting") public class HelloGreetingService { @Context private UriInfo context; /** Creates a new instance of HelloGreetingService */ public HelloGreetingService() { } /** * Retrieves representation of an instance of com.sun.rest.HelloGreetingService * @return an instance of java.lang.String */ @GET @Produces("text/html") public RESTGreeting getHtml(@QueryParam("name") String name) { return new RESTGreeting( getGreeting(), name); } private String getGreeting() { return "Hello "; } /** * PUT method for updating or creating an instance of HelloGreetingService * @param content representation for the resource * @return an HTTP response with content of the updated or created resource. */ @PUT @Consumes("text/html") public void putHtml(String content) { } } However when i deploy it on Glassfish, and run it. It generate an exception. I try to debug using netbean 6.8, and figure out that this line return new RESTGreeting(getGreeting(), name); in HelloGreetingService.java cause the exception. But not sure why. Here is the stacktrace javax.ws.rs.WebApplicationException at com.sun.jersey.spi.container.ContainerResponse.write(ContainerResponse.java:268) at com.sun.jersey.server.impl.application.WebApplicationImpl._handleRequest(WebApplicationImpl.java:1029) at com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:941) at com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:932) at com.sun.jersey.spi.container.servlet.WebComponent.service(WebComponent.java:384) at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:451) at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:632) at javax.servlet.http.HttpServlet.service(HttpServlet.java:847) at org.apache.catalina.core.StandardWrapper.service(StandardWrapper.java:1523) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:279) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:188) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:641) at com.sun.enterprise.web.WebPipeline.invoke(WebPipeline.java:97) at com.sun.enterprise.web.PESessionLockingStandardPipeline.invoke(PESessionLockingStandardPipeline.java:85) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:185) at org.apache.catalina.connector.CoyoteAdapter.doService(CoyoteAdapter.java:332) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:233) at com.sun.enterprise.v3.services.impl.ContainerMapper.service(ContainerMapper.java:165) at com.sun.grizzly.http.ProcessorTask.invokeAdapter(ProcessorTask.java:791) at com.sun.grizzly.http.ProcessorTask.doProcess(ProcessorTask.java:693) at com.sun.grizzly.http.ProcessorTask.process(ProcessorTask.java:954) at com.sun.grizzly.http.DefaultProtocolFilter.execute(DefaultProtocolFilter.java:170) at com.sun.grizzly.DefaultProtocolChain.executeProtocolFilter(DefaultProtocolChain.java:135) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:102) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:88) at com.sun.grizzly.http.HttpProtocolChain.execute(HttpProtocolChain.java:76) at com.sun.grizzly.ProtocolChainContextTask.doCall(ProtocolChainContextTask.java:53) at com.sun.grizzly.SelectionKeyContextTask.call(SelectionKeyContextTask.java:57) at com.sun.grizzly.ContextTask.run(ContextTask.java:69) at com.sun.grizzly.util.AbstractThreadPool$Worker.doWork(AbstractThreadPool.java:330) at com.sun.grizzly.util.AbstractThreadPool$Worker.run(AbstractThreadPool.java:309) at java.lang.Thread.run(Thread.java:637)

  • Remove mailmerge data source via OpenXML

    - by Dan
    I have some code that uses OpenXML to open up a docx file, find all mailmerge fields, and replace them with data (ignoring the datasource that may have been provided). I initially tested this against a document created in Office 2007 and it seemed to work great. We then created one in 2003 based off an Excel spreadsheet data source and saved it to 2007 docx format. When we open the file produced by my code, Word warns the user that it is going to execute some SQL, specifically "SELECT * from 'Sheet1$'". It has options of Yes/No. Selecting Yes requires I find the data source. Selecting No brings me to the document, which appears to be correct. I'm not sure why I'm now seeing this pop up. Perhaps it's due to a different data source for the 2003 document? My hope was that there was a way to delete all references to any datasources and that the pop-up wouldn't show. I found this, but it doesn't seem to work. Any suggestions?

    Hi, I've been banging my head around with a @ViewScoped managed-bean. I'm using primeface's "schedule" component in order to display some events.

    I've got an Ajax call for log in here is the code: //if MOUSE class is clicked $('.mouse').click(function () { //get the form to submit and return a message //how to call the function var name = $('#name').val(); var pwd2 = $('#pwd2').val(); $.ajax({ type:"POST", url: "http://localhost:51870/code/Login.aspx", data: "{ 'name':'" + $('#name').val() + "', 'pwd':'" + $('#pwd2').val() + "' }", contentType: "application/json; charset=utf-8", dataType: "json", context: document.body, success: function () { //$(this).addClass("done"); $(this).hide(); $('.mouse, .window').hide(); } }); }); the problem is I can't seem to catch name and pwd variables in Login page's preinit event or page load event here is the code in c#: protected void Page_PreInit(object sender, EventArgs e) { //taking javascript argument in preinit event //from here I'll have to build the page for specific lookbook var name = Request.QueryString["name"]; var pwd = Request.QueryString["pwd"]; } protected void Page_Load(object sender, EventArgs e) { var name = Request.QueryString["name"]; var pwd = Request.QueryString["pwd"]; SignIn(name); } I can't seem to get username name and password in c# side, help is appreciated.

  • LINQ to SQL: filter nested objects with soft deletes

    - by Alex
    Hello everyone, I'm using soft deleting in my database (IsDeleted field). I'm actively using LoadWith and AssociateWith methods to retrieve and filter nested records. The thing is AssociateWith only works with properties that represents a one-to-many relationship. DataLoadOptions loadOptions = new DataLoadOptions(); loadOption.LoadWith<User>(u = > u.Roles); loadOption.AssociateWith<User>(u = > u.Roles.Where(r = > !r.IsDeleted)); In the example above I just say: I want to retrieve users with related (undeleted) roles. But when I have one-to-one relationship, e.g. Document - File (the only one file is related to the document) I'm unable to filter soft deleted object: DataLoadOptions loadOptions = new DataLoadOptions(); loadOption.LoadWith<Document>(d = > d.File); // the next certainly won't work loadOption.AssociateWith<File>(f = > !f.IsDeleted); So, is there any idea how to filter records within the one-to-one relationship? Thanks!

  • Japanese text garbled while passing to a http restlet service

    - by satish-gunuputi
    Hi , I have a perl client which is calling a http restlet service (put method). Some of the parameters in this call contain japanese text. when I printed the contents of these request parameters in the restlet service I found these chars garbled ! This is my PERL client code: my %request_headers = ( 'DocumentName' => $document_name, --> This name is a JAPANESE String 'DocumentDescription' => 'Test Japanese Chars', 'content-length' => 200, 'Content-Type' => 'application/octet-stream; charset=utf-8', 'User-Agent' => "JPCharTester", ); $s-write_request('PUT', '/test-document/TEST/TEST_DOCUMENT' , %request_headers, $content); in this call both the values of $context and $document_name are JAPANESE Strings. But ONLY the document_name is received as garbled in my backend service. Here goes the Service code: String URL_ENCODING = "UTF-8"; String documentName = requestHeaders.getFirstValue("DocumentName"); System.out.println("Encoded Document Name : "+documentName+" <<<"); --> documentName is garbled here try { documentName = URLDecoder.decode(documentName, URL_ENCODING); System.out.println(>>> Decoded Document Name : "+documentName+" <<<"); --> documentName is garbled here } catch (java.io.UnsupportedEncodingException ex) { throwException(ex.getMessage(), Status.SERVER_ERROR_INTERNAL, ex); } both the above log statements printed GARBLED TEXT !! Can someone tell me what is the mistake I am doing and how to fix this ? Thanks in advance for your help. Regards, Satish.

  • Problem with multiple event handling in JQuery

    - by Greg
    Hi everyone, I have a strange jquery problem with multiple event handlers. What I'm trying to achieve is this: User selects some text on the page If the selection is not empty - show a context menu If user clicks somewhere else - the context menu should disappear I'm having troubles with the above i.e. sometimes the context menu appears correctly, sometimes it appears and disappears straight after user makes a selection. Please help. See the relevant parts of my code below. Also when user selects a paragraph or a word by double clicking - context menu appears and quickly disappears again. var ContextMenu = { ... show: function(e) { var z = this; if (!this.shown) { if (this.contextMenu) { this.contextMenu.css({ left: e.pageX, top: e.pageY }).slideDown('fast'); this.shown = true; } var hideHandler = function() { z.hide(this); }; $(document.body).bind("click", hideHandler); } }, hide: function(hideHandler) { if (this.contextMenu && this.shown) { this.contextMenu.slideUp('fast'); this.shown = false; $(document.body).unbind("click", hideHandler); } } }; // Context menu display logic $(document.body).bind("mousedown mouseup", function(e) { if ((window.getSelection().toString() != "") && (!ContextMenu.shown)) { ContextMenu.show(e); } });

  • Cookies not present after using XMLHttpRequest

    - by Joe B
    I'm trying to make a bookmarklet to download videos off of YouTube, but I've come across a little problem. To detect the highest quality video available, I use a sort of brute force method, in which I make requests using the XMLHttpRequest object until a 404 isn't returned (I can't do it until a 200 ok is returned because YouTube redirects to a different server if the video is available, and the cross-domain policy won't allow me to access any of that data). Once a working URL is found, I simply set window.location to the URL and the download should start, right? Wrong. A request is made, but for reasons unknown to me, the cookies are stripped and YouTube returns a 403 access denied. This does not happen if the XML requests aren't made before it, i.e. if I just set the window.location to the URL everything works fine, it's when I do the XMLHttpRequest that the cookies aren't sent. It's hard to explain so here's the script: var formats = ["37", "22", "35", "34", "18", ""]; var url = "/get_video?video_id=" + yt.getConfig('SWF_ARGS')['video_id'] + "&t=" + (unescape(yt.getConfig('SWF_ARGS')['t'])) + "&fmt="; for (var i = 0; i < formats.length; i++) { xmlhttp = new XMLHttpRequest; xmlhttp.open("HEAD", url + formats[i], false); xmlhttp.send(null); if (xmlhttp.status != 404) { document.location = url + formats[i]; break } } That script does not send the cookies after setting the document.location and thus does not work. However, simply doing this: document.location = /get_video?video_id=" + yt.getConfig('SWF_ARGS')['video_id'] + "&t=" + (unescape(yt.getConfig('SWF_ARGS')['t'])) DOES send the cookies along with the request, and does work. The only downside is I can't automatically detect the highest quality, I just have to try every "fmt" parameter manually until I get it right. So my question is: why is the XMLHttpRequest object removing cookies from subsequent requests? This is the first time I've ever done anything in JS by the way, so please, go easy on me. ;)

  • WOT Bookmarklet

    - by S.A
    I'm trying to write a bookmarklet that will allow me to view the Web Of Trust (WOT) ratings for all the links on a page before visiting them. While WOT provides their own bookmarklet, it is not very useful since you need to visit the page first before viewing the rating. This will be used on SeaMonkey, so I can't just install the WOT extension, either. WOT has a Javascript API that allows you to activate the ratings on any page it is included in, so I am using that as a base. However, it never seems to work correctly as a bookmarklet. Here's one attempt where I tried to keep the code as close to the API as possible. I only modified the wotinject function so that it would work in a bookmarklet and added a timeout so that the rating widget wouldn't be loaded before jQuery. var wotprotocol = (document.location.protocol == "https:") ? "https://" : "http://"; var wotbase = wotprotocol + "api.mywot.com/widgets"; var wotinject = function(src) { document.body.appendChild(document.createElement("script")).src = wotbase + "/" + src + ".js"; }; var wotjquery = typeof(jQuery) != "undefined"; if (!wotjquery) { wotinject("jquery"); } void(window.setTimeout(wotinject, 200, "ratingwidget")); I can see the APIs being loaded in the status bar, but it doesn't do anything at all. Is there any way to get this working?

  • popup with dynamic menuitems, each menuitem is another popup

    - by encryptor
    I am building an extension that has a pop up whose elements are constructed by a function call everytime the mouse hovers over the popup option. I am able to achieve this. Now I need to have a popup for each of the menu item (inside the original popup) which is not dynamic though. I have this code, but it does not work: for (var m=0; m < localpubliclist.length; m++) { var newItem = document.createElement("menu"); newItem.setAttribute("label", publicdisplayname[m]); newItem.setAttribute("id", "public" + m); myMenuPopup.appendChild(newItem); var newpopup = document.createElement("menupopup"); newpopup.setAttribute("id","publicpop" + m); newItem.appendChild(newpopup); var new1= document.createElement("menuitem"); new1.setAttribute("label", "Home"); new1.setAttribute("id", "publichome" + m); newpopup.appendChild(new1); } doing this forms the first popup where i can see all my menu with names publicdisplayname[m]. each of these is to be a popup which displays "Home". This does not work. the second popup (popup on publicdisplayname[m]) does not open. i have been stuck on this for quite some time and have tried various things cut it doesnt work. Can we do this at all? can we have double dynamic popups?

  • LaTeX: bibliography per chapter.

    - by YuppieNetworking
    Hello all, I am helping a colleague with his PhD thesis and we need to present the bibliography at the end of each chapter. The question is: does anyone have a minimal working example for this case using latex+bibtex? The current document structure that we use is the following: main.tex chap1.tex chap2.tex ... chapn.tex biblio.bib Where main.tex contains packages, document declarations, macros and \includes for each chapter. biblio.bib is the only bibtex file (I think is easier to have all citations in one place). We have searched and tried with different latex packages, reading and following their documentation. Specifically, bibitems and chapterbib. bibitems successfully generates bu*.aux files, but when running bibtex for each one of them, an error occurs since there is no \bibdata element in the .aux file. chapterbib also generates a .aux file, but bibtex finishes with an error caused by using multiple \bibliography{file} in the .tex files (one per chapter). Some coworkers suggested using a separate bibtex file for each chapter, which could be a problem of maintenance in the future when citing the same publications in different chapters. We will like to continue having this document structure, if possible. So, if anyone could shed some light to this problem, we will appreciate it. Thanks.

  • How to access attributes using Nokogiri

    - by Liz
    I have a simple task of accessing the values of some attributes. Below is a simple script that uses Nokogiri::XML::Builder to create a simple xml doc. require 'nokogiri' builder = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml| xml.Placement(:messageId => "392847-039820-938777", :system => "MOD", :version => "2.0") { xml.objects { xml.object(:myattribute => "99", :anotherattrib => "333") xml.nextobject_ '9387toot' xml.Entertainment "Last Man Standing" } } end puts builder.to_xml puts builder.root.attributes["messageId"] The results are below: <?xml version="1.0" encoding="UTF-8"?> <Placement messageId="392847-039820-938777" version="2.0" system="MOD"> <objects> <object anotherattrib="333" myattribute="99"/> <nextobject>9387toot</nextobject> <Entertainment>Last Man Standing</Entertainment> </objects> </Placement> C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/document.rb:178:in `add_child': Document already has a root node (RuntimeError) from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/node.rb:455:in `parent=' from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/builder.rb:358:in `insert' from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/builder.rb:350:in `method_missing' from C:/Documents and Settings/etrojan/workspace/Lads/tryXPATH2.rb:15 The xml that is generated looks fine. However, my attempts to access attributes cause an error to be generated, "Document already has a root node". I don't understand why a puts statement would cause this error. Any suggestions would be greatly appreciated.

  • What scalability problems have you solved using a NoSQL data store?

    - by knorv
    NoSQL refers to non-relational data stores that break with the history of relational databases and ACID guarantees. Popular open source NoSQL data stores include: Cassandra (tabular, written in Java, used by Facebook, Twitter, Digg, Rackspace, Mahalo and Reddit) CouchDB (document, written in Erlang, used by Engine Yard and BBC) Dynomite (key-value, written in C++, used by Powerset) HBase (key-value, written in Java, used by Bing) Hypertable (tabular, written in C++, used by Baidu) Kai (key-value, written in Erlang) MemcacheDB (key-value, written in C, used by Reddit) MongoDB (document, written in C++, used by Sourceforge, Github, Electronic Arts and NY Times) Neo4j (graph, written in Java, used by Swedish Universities) Project Voldemort (key-value, written in Java, used by LinkedIn) Redis (key-value, written in C, used by Engine Yard, Github and Craigslist) Riak (key-value, written in Erlang, used by Comcast and Mochi Media) Ringo (key-value, written in Erlang, used by Nokia) Scalaris (key-value, written in Erlang, used by OnScale) ThruDB (document, written in C++, used by JunkDepot.com) Tokyo Cabinet/Tokyo Tyrant (key-value, written in C, used by Mixi.jp (Japanese social networking site)) I'd like to know about specific problems you - the SO reader - have solved using data stores and what NoSQL data store you used. Questions: What scalability problems have you used NoSQL data stores to solve? What NoSQL data store did you use? What database did you use before switching to a NoSQL data store? I'm looking for first-hand experiences, so please do not answer unless you have that.
