  • When using TCP load balancing with HAProxy, does all outbound traffic flow through the LB?

    - by user122875
    I am setting up an app to be hosted using VMs(probably amazon, but that is not set in stone) which will require both HTTP load balancing and load balancing a large number(50k or so if possible) of persistant TCP connections. The amount of data is not all that high, but updates are frequent. Right now I am evaluating load balancers and am a bit confused about the architecture of HAProxy. If I use HAProxy to balance the TCP connections, will all the resulting traffic have to flow through the load balancer? If so, would another solution(such as LVS or even nginx_tcp_proxy_module) be a better fit?

  • Get notified when objective-c dom updates are ready initiated from webview

    - by Josh
    I am programmatically updating the DOM on a WebKit webview via DOMElement objects - for complex UI, there is usually a javascript component to any element that I add. This begs the need to be notified when the updates complete -- is there any such event? I know regular divs dont fire an onload or onready event, correct? The other assumption I had, which may be totally wrong, is that DOMElement updates aren't synchronous, so I can't do something like this and be confident it will meet with the label actually in the DOM: DOMElement *displayNameLabel = [document createElement:@"div"]; [displayNameLabel setAttribute:@"class" value:@"user-display-name"]; [displayNameLabel setTextContent:currentAvatar.avatarData.displayName]; [[document getElementById:@"user-card-content"] appendChild:displayNameLabel]; id win = [webView windowScriptObject]; [win evaluateWebScript:@"javascriptInstantiateLabel()"]; Is this true? I am using jquery within the body of the html already, so I don't mind subscribing to a particular classes set of events via "live." I thought I might be able to do something like: $(".some-class-to-be-added-later").live( "ready", function(){ // Instantiate some fantastic javascript here for .some-class }); but have experienced no joy so far. Is there any way on either side (objective-c since I don't programmatically firing javascript post load, or javascript) to be notified when the element is in the DOM? Thanks, Josh

  • catch-22 with apt-get

    - by Mark J Seger
    I'd recently installed a package and discovered my scp stopped working. After removing and installing some things I got it fixed but then I stated getting errors in apt-get about dpkg: error: configuration error: /etc/dpkg/dpkg.cfg.d/multiarch:1: unknown option 'foreign-architecture' so I commented it out and thought that fixed the problem until I discovered the chrome icon in my launcher turned into a ? and chrome no longer worked. I tried to reinstall it and got the apt-get error: "ambiguous package name 'libglib2.0-0' with more than one installed instance" if I try to remove libglib2 I get the error The following packages have unmet dependencies: iceape-browser : Depends: iceape but it is not going to be installed iceape-chatzilla : Depends: iceape (>= 2.7.11) but it is not going to be installed Depends: iceape (<= 2.7.11-1.1~) but it is not going to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. so then I tried to remove icape-browser and it complained about the 2 instances of libglinb2. in fact virtually any command I issue does the same thing so I don't know what I can do to untangle things.

  • The Webbrowser DocumentComplited event wont fire c#

    - by Igal B.
    Hi. I have a problem using C# Webbrowser control. the problem is with the event DocumentComplited. Usually the event works fine. the problem is with this page:http://www.voiproblem.com/emulators/Netgear/WGR614v6/fw_forward.html when I (automatically) press on "add" the control navigates to:http://www.voiproblem.com/emulators/Netgear/WGR614v6/pforward.html. but it never firing the DocumentComplited event. I build a simple application that does the same and there it works fine. I mean when the app invokes InvokeMember("click") it does go to the DocumentComplited event. in my real app it doesnt. anyone can help me to figure it up what is the problem? thanks. <code> private void button1_Click(object sender, EventArgs e) { webBrowser1.Navigate("http://www.voiproblem.com/emulators/Netgear/WGR614v6/fw_forward.html"); } private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { HtmlElement elm = webBrowser1.Document.GetElementById("Add"); if (elm != null) webBrowser1.Document.GetElementById("Add").InvokeMember("click"); } </code>

  • Using HTML5 on iPhone - cannot pause

    - by Ariel
    Hey guys, I was wondering whether anyone has tried to use the new tag that comes with HTML5 on the iPhone. Specifically, I didn't manage to make the pause() command to work. Below is a portion of the page. As you can see, I'm trying to pause the video 10sec after it started. It works on Safari on a Mac btw. Has anyone managed to make this work? <head> <javascript language="JavaScript"> function timeUpdate() { var myVideo = document.getElementsByTagName('video')[0]; var time = myVideo.currentTime; if (time > 10) { myVideo.pause(); } } function addListeners() { var myVideo = document.getElementsByTagName('video')[0]; myVideo.addEventListener('timeupdate',timeUpdate,false); } </script> </head> <body onload="addListeners()"> <video controls src="resources/bb_poor_cinderella_512kb.mp4" poster="resources/background.png"> Video tag not supported! </video> </body> Thanks, Ariel

  • Custom Jquery slideshow doesn't want to reset?

    - by Jared
    Hello, Under $(document).ready(function(), I have the following code: num = $("#mainContentCategoryLinksWrapper > div").size(); This makes num equal the length of the children of #mainContentCategoryLinksWrapper. Currently, this equals 4. Above the $(document).ready(function( I have this: var timesRun = 0; function slideshow(){ if(timesRun < num){ $(".arrowIn").stop().animate({color: "#a12324", textIndent: "30px", backgroundPosition: '0px 0px'}, 100, function(){ //the first child in the series has a class of "arrowIn" $(".arrowIn").next().addClass("replaceMe"); //Adds the ".replaceMe" placeholder the the next element. $(".arrowIn").removeClass("arrowIn"); //Deletes the class on the current element $(".replaceMe").addClass("arrowIn").removeClass("replaceMe"); //reassigns ".arrowIn" over ".replaceMe" timesRun = timesRun + 1; //increases number of times run }).prev().animate({color: "#000000", textIndent: "25px", backgroundPosition: '0px -25px'}, {duration: 50}); //puts the previous element back to it's original position }else{ timesRun = 0; $(".arrowIn").removeClass("arrowIn"); $("#mainContentCategoryLinksWrapper:first-child").addClass("arrowIn"); //this is supposed to reset timesRun, and set the first child in the series back to the original ".arrowIn" } } setInterval( 'slideshow()', 1000 ); So here is the what the code does: 1) Animates the first in the series of 4 (#1) timesRun = 1 2) Animates the second in the series of 4 (#2) timesRun = 2 3) Animates the third in the series of 4 (#3) timesRun = 3 4) Animates the fourth in the series of 4 (#4) timesRun = 4 5) timesRun is now longer less than num. Reset class names back to original to .arrowIn, set timesRun to 0. However, when the slideshow() is reexectuted, it doesn't start over. Any ideas? See www.raceramps.com/v3 for an example.

  • Vim, LaTeX, word-wrapping, and version control

    - by Bkkbrad
    I'm writing a LaTeX document in vim, and I have it hard wrapping at 80 characters to make reading easier. However, this causes problems with tracking changes with in version control. For example, inserting "Lorem ipsum" at the beginning of this text: 1 Dolor sit amet, consectetur adipiscing elit. Phasellus bibendum lobortis lectus 2 quis porta. Aenean vestibulum magna vel purus laoreet at molestie massa 3 suscipit. Vestibulum vestibulum, mauris nec convallis ultrices, tellus sapien 4 ullamcorper elit, dignissim consectetur justo tellus et nunc. results in: 1 Lorum ipsum dolor sit amet, consectetur adipiscing elit. Phasellus bibendum 2 lobortis lectus quis porta. Aenean vestibulum magna vel purus laoreet at 3 molestie massa suscipit. Vestibulum vestibulum, mauris nec convallis ultrices, 4 tellus sapien ullamcorper elit, dignissim consectetur justo tellus et nunc. When I review this change in git, it tells me that all the lines of the paragraph have changed because of the wrapping, even though only one semantic change has occurred. One way around this problem is to have every sentence on its own line. This looks the same in the rendered document, but the source now is harder to read, because each line has quite a different line length: 1 Lorum ipsum dolor sit amet, consectetur adipiscing elit. 2 Phasellus bibendum lobortis lectus quis porta. 3 Aenean vestibulum magna vel purus laoreet at molestie massa suscipit. 4 Vestibulum vestibulum, mauris nec convallis ultrices, tellus sapien ullamcorper elit, dignissim consectetur justo tellus et nunc. (If I soft wrap at 80, things still look bad, just in a different way.) Is it possible to have my text on disk with one newline per sentence, but display and edit it in vim as if the text of each paragraph was one long line, soft wrapped at 80 characters? I assume it requires some vim-foo rather than tweaking git or LaTeX.

  • if/else statement in a function: using onclick as a switch

    - by Aurora Schmidt
    I have looked for solutions to this on google for what seems like an eternity, but I can't seem to formulate my search correctly, or nobody has posted the code I'm looking for earlier. I am currently trying to make a function that will modify one or several margins of a div element. I want to use an if/else statement within the function, so that the onclick event will switch between the two conditions. This is what I have been working on so far; function facebookToggle() { if($('#facebooktab').style.margin-left == "-250px";) { document.getElementById("facebooktab").style.marginLeft="0px"; } else { document.getElementById("facebooktab").style.marginLeft="-250px"; } } I have tried twisting it around a little, like switching between "marginLeft" and "margin-left", to see if I was just using the wrong terms.. I'm starting to wonder if it might not be possible to combine jQuery and regular javascript? I don't know.. It's all just guesses on my part at this point. Anyway, I have a div, which is now positioned (fixed) so almost all of it is hidden outside the borders of the browser. I want the margin to change onclick so that it will be fully shown on the page. And when it is shown, I want to be able to hide it again by clicking it. I might be approaching this in the wrong way, but I really hope someone can help me out, or even tell me another way to get the same results. Thank you for any help you can give me. You can see it in action at: http://www.torucon.no/test/ (EDIT: By the way, I am a complete javascript novice, I have no experience with javascript prior to this experiment. Please don't be too harsh, as I am aware I probably made some really stupid mistakes in this short code.) EDITED CODE: function facebookToggle() { if($('#facebooktab').css('margin-left', '-250px') { $('#facebooktab').css('margin-left', '0px'); } else { $('#facebooktab').css('margin-left', '-250px'); } }

  • How to save a HTMLElement (Table) in localStorage?

    - by Hagbart Celine
    I've been trying this for a while now and could not find anything online... I have a project, where tablerows get added to a table. Works fine. Now I want to save the Table in the localStorage, so I can load it again. (overwrite the existing table). function saveProject(){ //TODO: Implement Save functionality var projects = []; projects.push($('#tubes table')[0].innerHTML); localStorage.setItem('projects', projects); //console.log(localStorage.getItem('projects')); The problem is the Array "projects" has (after one save) 2000+ elements. But all I want is the whole table to be saved to the first (or appending later) index. In the end I want the different Saves to be listed on a Option element: function loadSaveStates(){ alert('loading saved states...'); var projects = localStorage.getItem('projects'); select = document.getElementById('selectSave'); //my Dropdown var length = projects.length, element = null; console.log(length); for (var i = 0; i < length; i++) { element = projects[i]; var opt = document.createElement('option'); opt.value = i; opt.innerHTML = 'project ' + i; select.appendChild(opt); } } Can anyone tell me what I am doing wrong?

  • Working WCF WebServices with NLB server

    - by gguth
    Im starting the architecture of a new project using WCF, but im not the right person to make some network considerations, so im doing some research but cannot find the answers to these questions: We´ll host the WCF service in a common Windows Service app in 2 servers and we´ll have another server to make the Load-Balancing job using the WNLB. The fact that we are hosting the WCF in a Windows Service app can disturb the NLB job? Before my research i thought the load balancing was tought to configure, but with NLB it seems to be very simple, its really that simple? Note: The binding will be basicHttpBinding

  • Suscribers locking during snapshot replication

    - by remi_bourgarel
    Hi all :) Here is my architecture : I have a main server and 4 replica (the servers are synchronized with snapshot replication). The replication is working fine, except for one thing : during the replication a lot of SELECT request on one of the replica fail with a time-out. Here are my questions : Can I avoid these time-out ? If I can't : how can I detect the start and the end of the replication to redirect all the request on one of the replica to the main ? Thanks Sorry if you already answered to that kind of question but I couldn't find anything.

  • Is there a tag in XHTML that you can put anywhere in the body - even inside TABLE elements?

    - by Iain Fraser
    I would like to be able to place an empty tag anywhere in my document as a marker that can be addressed by jQuery. However, it is important that the XHTML still validates. To give you a bit of background as to what I'm doing: I've compared the current and previous versions of a particular document and I'm placing markers in the html where the differences are. I'm then intending to use jQuery to highlight the parent block-level elements when highlightchanges=true is in the URL's query string. At the moment I'm using <span> tags but it occurred to me that this sort of thing wouldn't validate: <table> <tr> <td>Old row</td> </tr> <span class="diff"></span><tr> <td>Just added</td> </tr> </table> So is there a tag I can use anywhere? Meta tag maybe? Thanks for your help! Iain

  • Dynamically populated NSPopUpButtonCell menu in an NSOutlineView

    - by Mo
    I’m working with an NSOutlineView which has two columns. My dataSource supplies the outline view with a tree of items of a custom class which represents file types (that is, you initialise it with a UTI). The first column is the display name of the file type (e.g., “Source code”, “Interface Builder NIB document”, etc.). The second column is an NSPopUpButtonCell which is supposed to allow the user to pick a handler for the given document type (think of Xcode’s “File Types” preference pane, and you’re pretty much there). I can generate an NSMenu for a given item in the tree, populated with options based upon the Launch Services database entries for the UTI, complete with the relevant application icon and and so on. In fact, the menu itself works wonderfully, populated by way of NSPopUpButtonCellWillPopUpNotification. The problem is, try as I might, the cell when the menu isn’t popped up always contains precisely one of two things: either an empty string, or the default text for the cell, the former if the result of -handlerName on the item (the attribute assigned to the column) is non-nil, the latter otherwise. Moreover, I’m manually calling -selectItem: on the NSPopUpButtonCell instance, which just seems Wrong. In contrast, the left-hand column, which is just an NSTextFieldCell, everything just works (although granted, all it’s got to do is read the value from the item and present it). (Disclaimer: I’m fairly new at Cocoa UI stuff; I know Objective-C, and lots of other programming languages, but I’ve not a huge amount of experience of building Mac OS X UIs, so be gentle).

  • JQuery function not working as expected

    - by Mike
    I've written a little function to position a logo midway between the left hand side of the browser window and the (centered) navigation menu. The menu items are populated from a database, with the first item given the id item0. function positionLogo(){ var $menuleft=0; var $element=document.getElementById('item0'); if ($element.offsetParent) { do { $menuleft+=$element.offsetLeft; } while ($element=$element.offsetParent); } var $logoleft=($menuleft/2)-130; // As logo is 260px wide if ($logoleft<0) { $logoleft=0; } $('#logo').css('left',$logoleft); } $(document).ready(function(){ positionLogo(); }); $(window).resize(function(){ positionLogo(); }); This works fine when the window is resized, but when it first runs when the page is loaded, the position it sets is about 20px too far right (ie $logoleft is 20 more than it should be). As soon as the page is resized it jumps into the correct position. Haven't got it live anywhere at the moment but does anyone have any ideas? Thanks!

  • VBScript: Disable caching of response from server to HTTP GET URL request

    - by Rob
    I want to turn off the cache used when a URL call to a server is made from VBScript running within an application on a Windows machine. What function/method/object do I use to do this? When the call is made for the first time, my Linux based Apache server returns a response back from the CGI Perl script that it is running. However, subsequent runs of the script seem to be using the same response as for the first time, so the data is being cached somewhere. My server logs confirm that the server is not being called in those subsequent times, only in the first time. This is what I am doing. I am using the following code from within a commercial application (don't wish to mention this application, probably not relevant to my problem): With CreateObject("MSXML2.XMLHTTP") .open "GET", "http://myserver/cgi-bin/nsr/nsr.cgi?aparam=1", False .send nsrresponse =.responseText End With Is there a function/method on the above object to turn off caching, or should I be calling a method/function to turn off the caching on a response object before making the URL? I looked here for a solution: http://msdn.microsoft.com/en-us/library/ms535874(VS.85).aspx - not quite helpful enough. And here: http://www.w3.org/TR/XMLHttpRequest/ - very unfriendly and hard to read. I am also trying to force not using the cache using http header settings and html document header meta data: Snippet of server-side Perl CGI script that returns the response back to the calling client, set expiry to 0. print $httpGetCGIRequest-header( -type = 'text/html', -expires = '+0s', ); Http header settings in response sent back to client: <html><head><meta http-equiv="CACHE-CONTROL" content="NO-CACHE"></head> <body> response message generated from server </body> </html> The above http header and html document head settings haven't worked, hence my question.

  • Getting the highlighted text inside selected element only.

    - by ashays
    My goal is to be able to get the highlighted text within a document, but only if that text is within a given section, and then apply a certain style to that selected text after clicking a div tag. I'll explain what I mean: So, having looked at window.getSelection() and document.selection.createRange().text, I attempted to use elmnt.getSelection() or elmnt.selection.createRange().text for some HTML element, elmnt. However, it doesn't seem to work, so that idea seems pretty null. This means I can't use this idea to determine the text that is highlighted within a given location. In case this doesn't make sense, essentially, I want html code that looks like this: <body> <div id="content">Stuff here will not be effected</div> <div id="highlightable">Stuff here can be effected when highlighted</div> <div id="morecontent">Stuff here will also not be effected</div> </body> So that whenever I've highlighted text, clicking on a specified div will apply the proper CSS. Now, on to the div tags. Basically, here's what I've got on that: $('.colorpicker').click( function(e) { console.log(getSelectedText()); } Eventually, all I want this to highlight the selected text and have the div tag change the color of the selected text to that of the respective div tag that I've selected. Neither of these seems to be working right now, and my only guess for the reason of the div tag is that it unhighlights whatever I've got selected whenever I click on the div tag. Fallbacks: If there is more than one time that 'abc' is found on the page and I highlight to color 'abc', I would like that only that copy of 'abc' be highlighted. I know this is a lot in one question, but even if I could get a little head start on this idea, my next personal project would be going a lot more smoothly. Thanks. :)

  • Using Javascript to expand DIVs and go to anchor text

    - by radiantjoy
    I apologize that this question is so similar to "How can you check for a #hash in a URL using JavaScript?" but would appreciate your help with the following. I would like to use Javascript to display text that is a) identified by an anchor. b) contained within 2 collapsed DIVs....ONLY WHEN the anchor is in the URL. Otherwise, the page should display with all DIVs collapsed. Something like this: if (theHashIsABC) { Expand 2 DIVs on the page and go to the anchor; } else { just display the page; } Specifics: 1. Using IE7 2. DIVs ids to be expanded '8589' and '6212' out of several DIVs on the page 3. Anchor name is anchorABC I have been told that it is not possible to expand some DIVs in IE7 so I am thinking I need to expand all DIVs on the page. [ I can expand just the 2 with a link within the page: <a class="jumplink" href="javascript:toggleBlock('6212');toggleBlock('8589')";link to expand DIVs</a> ] This is what I have so far (in head section)... if(window.location.hash = "anchorABC") { //this works with a button on the page that expand all divs function showAll(pstrClass) { var aElts = document.getElementsByTagName('div'); setDisplay(pstrClass, aElts, 'show', 'Block'); aElts = document.getElementsByTagName('span'); setDisplay(pstrClass, aElts, 'show', 'Inline'); //would also like the page to move to the anchor } else { // just display the page } In advance, thank you for your time.

  • Double Click and Resize on an Ipad

    Thanks to the great post at OranLooney.com I was able to get a java/icefaces web-app to resize nicely on the ipad, however the code provided for double click doesn't seem to work without further customization. Has anybody had any experience with getting this to work? there seems to be little documentation on google. the donnothing(); in the window.orientationchange is there as it seems sometimes without it the resize will (sometimes) not work // a function to parse the user agent string; useful for // detecting lots of browsers, not just the iPad. function checkUserAgent(vs) { var pattern = new RegExp(vs, 'i'); return !!pattern.test(navigator.userAgent); } if ( checkUserAgent('iPad') ) { // iPad specific stuff here window.onorientationchange = function() { donnothing(); }; document.body.addEventListener('touchstart', function(e) { touch = e.touches[0]; if ( !touch ) return; var me = document.createEvent("MouseEvents"); me.initMouseEvent('dblclick', true, true, window, 1, // detail / mouse click count touch.screenX, touch.screenY, touch.clientX, touch.clientY, false, false, false, false, // key modifiers 0, // primary mouse button null // related target not used for dblclick event ); touch.target.dispatchEvent(me); }); }

  • Undefined variable error when parsing json

    - by Ben Shelock
    I'm trying to parse the json grabbed from here. Basically what I do is iterate over the items, sort them, then display them. But I get an error saying data.data.children[i] is undefined. I can't think why it's doing it though? var json = 'http://www.reddit.com/reddits/mine/.json'; GM_xmlhttpRequest({ method: "GET", url: json, onload: reddits }); function reddits(response){ var txt = response.responseText; var data; var suggested = document.getElementById('suggested-reddits'); if(window.JSON && JSON.parse){ data = JSON.parse(txt); } else{ data = eval("("+txt+")"); } suggested.innerHTML += '<span>reddits you\'re subscribed to </span> <ul id="rsub"></ul>'; GM_addStyle('#rsub{width: 500px;}'); var reddits = new Array(); var rsub = document.getElementById('rsub'); for(i = 0; i <= data.data.children.length; i++){ var r = data.data.children[i].data.display_name; reddits.push(r); } sort(reddits); for(i = 0; i <= reddits.length; i++){ rsub.innerHTML += '<li><a href="#" onclick="set_sr_name(this); return false">' + reddits[i] + '</a></li>'; } }

  • Qt - QWebView Problem

    - by user547057
    Hi, I have a PyQt gui script which consists of a QWebView widget. I'm trying to send a GET request, i.e go to a page, fill a form and hit click using the code at the bottom of this question. Since i'm dealing with the documentElement(a QWebElement) of the webview, I need to place all DOM actions in a separate function(which I have named fillForm) and connect the loadFinished() signal into the function. Without connecting the signal, the document will not have loaded and I won't be able to get the elements I want. I'm able to submit the form correctly and get the proper response from the webpage. The problem i'm having is that, the above leads to a sort of infinite loop. This is because the webpage gets reloaded each time a new page is loaded, so the form gets filled each and every single time without stopping. I'd like to know if there's some way of finding out whether the WebView's page has loaded fully, non-asynchronously or maybe pause execution of the script(without freezing the gui) until the whole document has loaded. I'm unable to come up with a satisfactory solution(my idea consisted of keeping a global variable to track clicks) to this problem. I would appreciate it if someone could help me out with a better way to tackle this. Thanks! Here's the code i'm using import sys from PyQt4.QtCore import * from PyQt4.QtGui import * from PyQt4.QtWebKit import * from PyQt4 import QtCore app = QApplication(sys.argv) web = QWebView() web.load(QUrl("http://mywebsite.com")) def fillForm(): doc = web.page().mainFrame().documentElement() searchform = doc.findFirst("input[type=text]") searchform.setAttribute("value", "hello") button = doc.findFirst("input[type=submit]") button.evaluateJavaScript("click()") QtCore.QObject.connect(web, QtCore.SIGNAL("loadFinished"), fillForm) web.show() sys.exit(app.exec_())

  • How do I render *parts* of a svg file?

    - by Fake Code Monkey Rashid
    Hello good people! :) I want to render parts of a svg file by name but for the life of me I cannot figure out how to do so (using python + gtk). Here's the svg file in question: http://david.bellot.free.fr/svg-cards/files/SVG-cards-2.0.1.tar.gz On his site, David, says: You can draw a card either by rendering the file onto a pixmap and clipping each card manually or by using the card's name through a DOM interface. All cards are embedded into a SVG group. I don't know what he means by a DOM interface. I have done some searching and the best result I found that seems to fit what I want to do is: QSvgRenderer *renderer = new QSvgRenderer(QLatin1String("SvgCardDeck.svg")); QGraphicsSvgItem *black = new QGraphicsSvgItem(); QGraphicsSvgItem *red = new QGraphicsSvgItem(); black->setSharedRenderer(renderer); black->setElementId(QLatin1String("black_joker")); red->setSharedRenderer(renderer); red->setElementId(QLatin1String("red_joker")); Notice however that it is for Qt and is not even written in python. This is what I have so far: #!/usr/bin/env python from __future__ import absolute_import import cairo import gtk import rsvg from xml import xpath from xml.dom import minidom window = gtk.Window() window.set_title("Foo") window.set_size_request(256, 256) window.set_property("resizable", False) window.set_position(gtk.WIN_POS_CENTER) window.connect("destroy", gtk.main_quit) window.show() document = minidom.parse("cards.svg") element = xpath.Evaluate("//*[@id='1_club']", document)[0] xml = element.toxml() svg = rsvg.Handle() svg.write(xml) pixbuf = svg.get_pixbuf() image = gtk.Image() image.set_from_pixbuf(pixbuf) image.show() window.add(image) gtk.main() It doesn't work, of course. What am I missing?

  • Java Framework Choice Question.

    - by Sarang
    We do have many frameworks available in Java. Struts, Swing, JSF 2.0, Spring etc are used as per their priority. Actually, I don't know how many they are as well! But, as I am fresher to Java, even learning after their architecture, I cannot decide which framework can be used with what type of Projects ! Also, I am confused with mixed use of framework like Spring + JSF. What is the benefit to it ? Another thing making me confusing is about the UI components available in market. Like, we do have Primefaces, Ice-faces, MyFaces, Rich-faces. They may or may not have been supporting AJAX in-built. They may contains some bugs as well. What is best choice for Framework + UI component that can directly provide a best feet solution for any project ?
