• Facebook offline access step-by-step

  - by Ben

  After searchinge litteraly 1 day on fb and google for an up-to-date and working way to do something seemingly simple: I am looking for a step-by-step explanation to get offline_access for a user for a facebook app and then using this (session key) to retrieve offline & not within a browser friends & profile data. Preferrably doing this in the Fb Java API. Thanks. And yes I did check the facebook wiki. Update: Anyone? this: http://www.facebook.com/authorize.php?api_key=<api-key>&v=1.0&ext_perm=offline_access gives me offline_Access, however how to retrieve the session_key? Why can't facebook just do simple documentation, I mean there are like 600 people working there? The seemingly same question: http://stackoverflow.com/questions/617043/getting-offlineaccess-to-work-with-facebook Does not answer how to retrieve the session key Edit: I am still stuck with that. I guess nobody really tried such a batch access out yet...

• Sorting by custom field and fetching whole tree from DB

  - by Niaxon

  Hello everyone, I am trying to do file browser in a tree form and have a problem to sort it somehow. I use PHP and MySQL for that. I've created mixed (nested set + adjacency) table 'element' with the following fields: element_id, left_key, right_key, level, parent_id, element_name, element_type (enum: 'folder','file'), element_size. Let's not discuss right now that it is better to move information about element (name, type, size) into other table. Function to scan specified directory and fill table work correctly. Noteworthy, i am adding elements to tree in specific order: folders first and then files. After that i can easily fetch and display whole table on the page using simple query: SELECT * FROM element WHERE 1=1 ORDER BY left_key With the result of that query and another function i can generate correct html code (<ul><li>... and so on). to display tree. Now back to the question (finally, huh?). I am struggling to add sorting functionality. For example i want to order my result by size. Here i need to keep in my mind whole hierarchy of tree and rule: folders first, files later. I believe i can do that by generating in PHP recursive query: SELECT * FROM element WHERE parent_id = {$parentId} ORDER BY element_type (so folders would be first), size (or name for example) asc/desc After that for each result which has type = 'folder' i will send another query to get it's content. Also it's possible to fetch whole tree by left_key and after that sort it in PHP as array but i guess that would be worse :) I wonder if there is better and more efficient way to do such a thing?

• Anchor tags are blank

  - by ryanday

  I'm having a problem where the my anchor tags sometimes aren't displaying their links. This is happening on Mobile Safari on multiple iPhones, and in the iPhone simulator. I'm using jQtouch r147, PhoneGap, and jQuery 1.4.2. I'm generating the data from a database call, and adding anchor tags to a list like this: for(var i=0;i<data.rows.length;i++) { var item = $('<li></li>'); var name = data.rows.item(i).name; var anchor = $('<a href="#lpage">'+name+'</a>'); item.addClass('arrow'); // This line always displays the name, even when I can't see // the name in the browser debug.log('The name: ' + name); (function(info) { anchor.bind('tap', function(e) { debug.log('Touch start ' + info.id); }); })(data.rows.item(i)); item.append(anchor); if( anchor.html() == null ) { debug.log('html is blank'); } $('#myUL').append(item); } Sometimes my list of names shows fine(http://imagebin.org/101462), and sometimes it is just blank(http://imagebin.org/101464). When the list is blank, I see the debug.log() line show me 'html is blank', and I also see the log line show me that the variable 'name' does, in fact, contain a valid name. When I check for anchor.html() == null, I've also tried to .remove() the anchor tag, and re-create it. But it always comes back without the name displayed. This happens on the mobile device and in the simulator, but I've never seen it happen in Safari or in Chrome. Has anyone seen something like this? I can't find the cause, and I can't get it to stop. Thank you for any ideas or suggestions!

Should i just put my sendmail php inside of my successful php? Or can someone explain to me why $notes is blank. I do have my recaptcha key in, and also i do have an email address. I kept some things private, also there is a notes textarea in my HTML

• jquery live and callbacks via wcf services

  - by vondip

  Hi all, I am writing a web app with asp.net, c# and jquery. Most of the time I'm writing dynamic html to the browser and using different web services to get the content needed. My call to the service: function WriteProducts(currentIndex, selectedCategoryId, callback) { var d = new Date(); MyAppServices.GetProducts(selectedCategoryId, currentIndex, 8, d.getTime().toString(), callback, function func() { alert('failure'); }); } The request usually gets translated to this (using firebug I monitored it): http://localhost:8080/MyApp/MyAppServices.svc/GetProducts?categoryId=0&fromIndex=0&toIndex=8&randomNumber=%221271800014441%22 The problem starts when part of the html controls dynamically rendered need to respond to click events. This is when I start using jquery's live method: $('.filter').live('click', function(event) { WriteProducts(0, selectedCategoryId, PopulateDivs); }); Now from some reason, the request passed to the server becomes this: http://localhost:8080/MyApp/MyAppServices.svc/GetProducts?categoryId=**%2217%22**&fromIndex=0&toIndex=8&randomNumber=%221271799783355%22 where did these %22 come from? If I take them out, the request passes successfully. I have no idea who inserted these %22, but they are causing havoc here! Guys, do you perhaps have a clue?

• Generate custom RSS/Atom feed with SyndicationFeedFormatter made from XML

  - by Sentax

  I have followed this article and implemented my service and I can open the web browser and see the test data being published. I would like to create a custom formatted response, as for my needs this will not be published to the internet and it's an isolated feed that other devices on the local network could read to get the data I'm publishing. I'd like to create an XML document and publish it instead of using the SyndicationItem that is being used in the article to display title, author, description, etc. Would like to create something simple to be published: <MyData> <ID>33883</ID> <Title>The Name</Title> <Artist>The Artist</Artist> </MyData> I know how to create that in an XMLWriter, but how to publish in a SyndicationFeedFormatter that is the return type for the function in the article? I have seen the XmlSyndicationContent class but haven't seen any practical examples that would accomplish what I want to do.

• architecture and tools for a remote control application?

  - by slothbear

  I'm working on the design of a remote control application. From my iPhone or a web browser, I'll send a few commands. Soon my home computer will perform the commands and send back results. I know there are remote desktop apps, but I want something programmable, something simpler, and something that I wrote. My current direction is to use Amazon Simple Queue Service (SQS) as the message bus. The iPhone places some messages in a queue. My local Java/JRuby program notices the messages on the queue, performs the work and sends back status via a different queue. This will be a very low-volume application. At $1.00 for a million requests (plus a handful of data transfer charges), Amazon SQS looks a lot more affordable than having my own server of any type. And super reliable, that's important for me too. Are there better/standard toolkits or architectures for this kind of remote control? Cost is not a big issue, but I prefer the tons I learn by doing it myself. I'm moderately concerned about security, but doubt it will be a problem. The list of commands recognized will be very short, and only recognized in specific contexts. No "erase hard drive" stuff. update: I'll probably distribute these programs to some other people who want the same function, but who don't have Amazon SQS accounts. For now, they'll use anonymous access to my queues, with random 80-character queue names.

• apache web server configuration problem

  i want to have apache server to serve only /var/www/ directory now it serves all my files on system from directory "/" i tried to edit httpd.conf placed in /etc/apache2 and placed the folllowing content in it(intially it was empty) <Directory /> Options None AllowOverride None </Directory> DocumentRoot "/var/www" <Directory "/var/www"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> then saved it,restarted apache server put the location /var/www in the web browser address bar,still it shows the higher level directories too then i edited the file Default,Default-ssl in the sites-available folder repeated the same process still apache serves all files on my system 2.when i try to use the following command gedit httpd.conf I get the error gedit:2696): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported GConf Error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash.

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)

• Does anchor href of an image make it download?

  - by matthewsteiner

  So I was using yslow for firefox and my page weight was way high. My page has a main product image and then maybe 10 thumbnails. If you click a thumbnail, the image opens up in a popup done through jquery. The problem is, yslow is listing even the targets of the thumbnails as part of the page weight, so I guess for some reason the images are downloading. For example, I have: <a class="group nyroModal" rel="lightbox-group" href="/upload/topview.jpg"> <img alt="thumbnail" src="/upload/thumb/t_topview.jpg" /> </a> Would this normal html cause the "upload/topview.jpg" to automatically download? Or is it the jquery plugin "nyroModal"? I'd rather the images didn't preload, that'd waste a lot of bandwidth. So my question is, does a browser automatically try to download image files that are in the href property of anchors, or is the plugin most likely causing this? Thanks for any direction you can give me.

• How to keep confirmation messages after POST while doing a post-submit redirect?

  - by MicE

  Hello, I'm looking for advise on how to share certain bits of data (i.e. post-submit confirmation messages) between individual requests in a web application. Let me explain: Current approach: user submits an add/edit form for a resource if there were no errors, user is shown a confirmation with links to: submit a new resource (for "add" form) view the submitted/edited resource view all resources (one step above in hierarchy) user then has to click on one of the three links to proceed (i.e. to the page "above") Progmatically, the form and its confirmation page are one set of classes. The page above that is another. They can technically share code, but at the moment they are both independent during processing of individual requests. We would like to amend the above as follows: user submits an add/edit form for a resource if there were no errors, the user is redirected to the page with all resources (one step above in hierarchy) with one or more confirmation messages displayed at the top of the page (i.e. success message, to whom was the request assigned, etc) This will: save users one click (they have to go through a lot of these add/edit forms) the post-submit redirect will address common problems with browser refresh / back-buttons What approach would you recommend for sharing data needed for the confirmation messages between the two requests, please? I'm not sure if it helps, it's a PHP application backed by a RESTful API, but I think that this is a language-agnostic question. A few simple solutions that come to mind are to share the data via cookies or in the session, this however breaks statelessness and would pose a significant problem for users who work in several tabs (the data could clash together). Passing the data as GET parameters is not suitable as we are talking about several messages which are dynamic (e.g. changing actors, dates). Thanks, M.

• Greasemonkey script not executed when unusual content loading is being used

  - by Sam Brightman

  I'm trying to write a Greasemonkey script for Facebook and having some trouble with the funky page/content loading that they do (I don't quite understand this - a lot of the links are actually just changing the GET, but I think they do some kind of server redirect to make the URL look the same to the browser too?). Essentially the only test required is putting a GM_log() on its own in the script. If you click around Facebook, even with facebook.com/* as the pattern, it is often not executed. Is there anything I can do, or is the idea of a "page load" fixed in Greasemonkey, and FB is "tricking" it into not running by using a single URL? If I try to do some basic content manipulation like this: GM.log("starting"); var GM_FB=new Object; GM_FB.birthdays = document.evaluate("//div[@class='UIUpcoming_Item']", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); for (i = GM_FB.birthdays.snapshotLength - 1; i >= 0; i--) { if (GM_FB.birthdayRegex.test(GM_FB.birthdays.snapshotItem(i).innerHTML)) { GM_FB.birthdays.snapshotItem(i).setAttribute('style','font-weight: bold; background: #fffe88'); } } The result is that sometimes only a manual page refresh will make it work. Pulling up the Firebug console and forcing the code to run works fine. Note that this isn't due to late loading of certain parts of the DOM: I have adding some code later to wait for the relevant elements and, crucially, the message never gets logged for certain transitions. For example, when I switch from Messages to News Feed and back.

• Why can't I make an http request to the ASP.NET development server on localhost?

  - by Chris Farmer

  I have an ASP.NET project (VS2008 on Windows 7 with either webforms, MVC1, or MVC2 -- all the same result for me) which is just the File-New hello world web project. It's using the default ASP.NET development server, and when I start the server with F5, the browser never connects and I get a timeout. I tried to debug this by telnetting to the development server's port while it was running, and I got the same result: C:\Users\farmercs>telnet localhost 54752 Connecting To localhost...Could not open connection to the host, on port 54752: Connect failed I can see in the system tray that the server thinks it's running, and a netstat -s -n command shows that there is indeed an active TCP listener on that port. This worked in the not-too-distant past, and I could work on web projects using the development server. One thing that has changed since then was that I installed the Microsoft Loopback Adapter to accommodate a local development Oracle installation. I'm not sure this is the problem, but it seems a likely culprit. So, what could be blocking me from connecting? And if it's the loopback, then what is a good way for me to retain my ability to connect to my development Oracle server while still being able to use the ASP.NET development server?

• How can I split my conkeror-rc config over multiple files?

  - by Ryan Thompson

  Short version: can you help me fill in this code? var conkeror_settings_dir = ".conkeror.mozdev.org/settings"; function load_all_js_files_in_dir (dir) { var full_path = get_home_directory().appendRelativePath(dir); // YOUR CODE HERE } load_all_js_files_in_dir(conkeror_settings_dir); Background I'm trying out Conkeror for web browsing. It's an emacs-like browser running on Mozilla's rendering engine, using javascript as configuration language (filling the role that elisp plays for emacs). In my emacs config, I have split my customizations into a series of files, where each file is a single unit of related options (for example, all my perl-related settings might be in perl-settings.el. All these settings files are loaded automatically by a function in my .emacs that simply loads every elisp file under my "settings" directory. I am looking to structure my Conkeror config in the same way, with my main conkeror-rc file basically being a stub that loads all the js files under a certain directory relative to my home directory. Unfortunately, I am much less literate in javascript than I am in elisp, so I don't even know how to "source" a file.

• Is A Web App Feasible For A Heavy Use Data Entry System?

  - by Rob

  Looking for opinions on this, we're working on a project that is essentially a data entry system for a production line. Heavy data input by users who normally work in Excel or other thick client data systems. We've been told (as a consequence) that we have to develop this as a thick client using .NET. Our argument was to develop as a web app, as it resolves a lot of issues and would be easier to write and maintain. Their argument against the web is that (supposedly) the web is not ready yet for a heavy duty data entry system, and that the web in a browser does not offer the speed, responsiveness, and fluid experience for the end-user that a thick client can (citing things such as drag and drop, rapid auto-entry and data navigation, etc.) Personally, I think that with good form design and JQuery/AJAX, a web app could do everything a thick client does just as well, and they just don't know what they're talking about. The irony is that a thick client has to go to a lot more effort to manage the deployment and connectivity back to the central data server than a web app would need to do, so in terms of speed I would expect a web app to be faster. What are the thoughts of those out there? Are there any technologies currently in production use that modern data entry systems are being developed as web apps in? Appreciate any feedback. Regards, Rob.

• Combine Search Bar and URL Bar into One (WebView)

  - by Jay Bush

  So I'm in the midst of updating my Web Browser app for iOS devices, from the ground up, and I'm trying to implement some more convenient features. One feature that seems to be really popular now, that I have been getting a lot of requests for, is the combination of a Google Search bar and a URL bar in one, like that of the Chrome application. Below is a screenshot of the Google Chrome app, and as you can see, they've made it so you can either enter in a search query like "apple ipad" and it will return a Google search page of 'Apple iPad', or you can enter in a URL "http://apple.com/ipad/" and it will load that URL. I have looked all over the internet, but all I could find were tutorials on how to Search Google with value of the UITextField. I have a feeling that the best way to do this is to probably make a 'check'. Like if the entered value contains 'http://' 'www.' '.com' or no spaces, then load it as a URL, if not then load it in a Google Search page, and then have the webview load up the Google Search page. If anybody could show me to the right direction, that would be great, or even supplying me with some code would be even greater. :) Thanks! If anyone needs part of the code, just ask.

• PHP Socket Server vs node.js: Web Chat

  - by Eliasdx

  I want to program a HTTP WebChat using long-held HTTP requests (Comet), ajax and websockets (depending on the browser used). Userdatabase is in mysql. Chat is written in PHP except maybe the chat stream itself which could also be written in javascript (node.js): I don't want to start a php process per user as there is no good way to send the chat messages between these php childs. So I thought about writing an own socket server in either PHP or node.js which should be able to handle more then 1000 connections (chat users). As a purely web developer (php) I'm not much familiar with sockets as I usually let web server care about connections. The chat messages won't be saved on disk nor in mysql but in RAM as an array or object for best speed. As far as I know there is no way to handle multiple connections at the same time in a single php process (socket server), however you can accept a great amount of socket connections and process them successive in a loop (read and write; incoming message - write to all socket connections). The problem is that there will most-likely be a lag with ~1000 users and mysql operations could slow the whole thing down which will then affect all users. My question is: Can node.js handle a socket server with better performance? Node.js is event-based but I'm not sure if it can process multiple events at the same time (wouldn't that need multi-threading?) or if there is just an event queue. With an event queue it would be just like php: process user after user. I could also spawn a php process per chat room (much less users) but afaik there are singlethreaded IRC servers which are also capable to handle thousands of users. (written in c++ or whatever) so maybe it's also possible in php. I would prefer PHP over Node.js because then the project would be php-only and not a mixture of programming languages. However if Node can process connections simultaneously I'd probably choose it.

• Open Select using Javascript/jQuery?

  - by Newbie

  Hello! Is there a way to open a select box using Javascript (and jQuery)? <select style="width:150px;"> <option value="1">1</option> <option value="2">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc arcu nunc, rhoncus ac dignissim at, rhoncus ac tellus.</option> <option value="3">3</option> </select> I have to open my select, cause of ie bug. All versions of IE (6,7,8) cut my options. As far as I know, there is no css bugfix for this. At the moment I try to do the following: var original_width = 0; var selected_val = false; if (jQuery.browser.msie) { $('select').click(function(){ if (selected_val == false){ if(original_width == 0) original_width = $(this).width(); $(this).css({ 'position' : 'absolute', 'width' : 'auto' }); }else{ $(this).css({ 'position' : 'relative', 'width' : original_width }); selected_val = false; } }); $('select').blur(function(){ $(this).css({ 'position' : 'relative', 'width' : original_width }); }); $('select').blur(function(){ $(this).css({ 'position' : 'relative', 'width' : original_width }); }); $('select').change(function(){ $(this).css({ 'position' : 'relative', 'width' : original_width }); }); $('select option').click(function(){ $(this).css({ 'position' : 'relative', 'width' : original_width }); selected_val = true; }); } But clicking on my select the first time will change the width of the select but I have to click again to open it.

• CSS overflow detection in JavaScript

  - by ring0

  In order to display a line of text (like in a forum), and end that line with "..." if the text would overflow the line (not truncating using the CSS overflow property), there are a number of ways. I'm still seeking the best solution. For instance, Adding in CSS a "..." as a background-image is a possibility, but it would appear all the time, and this is not a good solution. Some sites just count the characters and if over - say - 100, truncates the string to keep only 100 (or 97) chars and add a "..." at the end. But fonts are usually not proportional, so the result is not pretty. For instance the space - in pixels - taken by "AAA" and "iii" is clearly different "AAA" and "iii" via a proportional font have the same width There is another idea to get the exact size in pixels of the string: create in Javascript a DIV insert the text in it (via innerHTML for instance) measure the width (via .offsetWidth) which is not implemented yet. However, I wonder if there could be any browser compatibility problem? Did any one tried this solution? Other recommendations would be welcome.

• How to properly load HTML data from third party website using MVC+AJAX?

  - by Dmitry

  I'm building ASP.NET MVC2 website that lets users store and analyze data about goods found on various online trade sites. When user is filling a form to create or edit an item, he should have a button "Import data" that automatically fills some fields based on data from third party website. The question is: what should this button do under the hood? I see at least 2 possible solutions. First. Do the import on client side using AJAX+jQuery load method. I tried it in IE8 and received browser warning popup about insecure script actions. Of course, it is completely unacceptable. Second. Add method ImportData(string URL) to ItemController class. It is called via AJAX, does the import + data processing server-side and returns JSON-d result to client. I tried it and received server exception (503) Server unavailable when loading HTML data into XMLDocument. Also I have a feeling that dealing with not well-formed HTML (missing closing tags, etc.) will be a huge pain. Any ideas how to parse such HTML documents?

• IE6 ignoring active link CSS style

  The CSS active link style is being correctly applied in IE7, FF, and Safari but is not applied IE6. .side_nav a.active { color:#FFFFFF; background-color:#9F1F63; } Interestingly the background color (background-color:#9F1F63;) is being applied in IE6 but not the font color (color:#FFFFFF;) Any ideas on why this is happening and how I can fix it appreciated. The complete styling for the nav below: .side_nav { text-align : left; margin-left: -10px; } .side_nav ul { list-style-type: none; list-style-position:inside; margin-left:0px; } .side_nav li { margin-top: 10px; display: list-item; list-style-type:none; } .side_nav a, .side_nav a:visited { text-decoration: none; color : #9F1F63; font-weight : bold; padding: 5px 10px 5px 10px; } .side_nav a:hover { color:#B26D7F; } .side_nav a.active { color:#FFFFFF; background-color:#9F1F63; } EDIT: Thanks but the suggestions haven't helped. When I change to a:active the active effect does not work in any browser. I think this might be due to how I have applied the style in the HTML. <div class="side_nav"> <a class="active" href="Page1.aspx">Page1</a><br /> <a href="Page2.aspx">Page2</a><br /> <a href="Page3.aspx">Page3</a><br /> </div>

• Help with accessing a pre-existing window AFTER opener is refreshed!

  - by Wilhelm Murdoch

  Alright, I'm at my wit's end on this issue. First, backstory. I'm working on a video management system where we're allowing users, when adding new content, to upload and, optionally, transcode a media file. We're using Java applet for the browser-based FTP client. What I want to do is allow a user to initiate an upload and then send the FTP connection instance to a popup window. This window will act as a job queue for the FTP transfer process. This will allow users to move about the main interface without having to stay on the original page until an individual file transfer is complete. For the most part I have all of this working, but here's a problem. If the window is closed, all connections are dropped and the upload process for all queued files will be canceled. So, if Window One opens the Popup Window, adds stuff to the queue, refreshes the screen or moves to a different page, how will I access the Popup Window? The popup window and its contents must remain persistent while the user navigates through the original window. The original window must be able to access the popup to add a new job to the queue. The popup window itself is independent of the opening window, so communication only happens in one direction: Parent - Popup Not Parent <- Popup Window.open(null, 'WINDOW_NAME'); will not work in this case. I need to check if a window exists BEFORE using window.open. Help!?!?

• Problem using unicode in URLs with cgi.PATH_INFO in ColdFusion

  - by Loftx

  Hi there, My ColdFusion (MX7) site has search functionality which appends the search term to the URL e.g. http://www.example.com/search.cfm/searchterm. The problem I'm running into is this is a multilingual site, so the search term may be in another language e.g. ??????? leading to a search URL such as http://www.example.com/search.cfm/??????? The problem is when I come to retrieve the search term from the URL. I'm using cgi.PATH_INFO to retrieve the path of the search page and the search term and extracting the search term from this e.g. /search.cfm/searchterm however, when unicode characters are used in the search they are converted to question marks e.g. /search.cfm/??????. These appear actual question marks, rather than the browser not being able to format unicode characters, or them being mangled on output. I can't find any information about whether ColdFusion supports unicode in the URL, or how I can go about resolving this and getting hold of the complete URL in some way - does anyone have any ideas? Cheers, Tom

• Node-webkit works on Mac, crashes and can't load module on Windows

  - by user756201

  I've created a full node-webkit app that works fine on the Mac OSX version of node-webkit. Everything works, it loads a key external nodeJS module (marked), and the world is good. However, when I try to run the app on the Windows version of Node-webkit as described in the Wiki, the app crashes immediately (in fact, it crashes immediately when I try all the options: dragging a folder onto nw.exe, dragging an app.nw compressed folder, and running both from the command line). The only thing that gets me closer is opening nw.exe and then pointing the node-webkit location bar to the index file. Then I get this error: Uncaught node.js Error Error: Cannot find module 'marked' I tried commenting out the code that requires marked: var marked = require('marked'); That returns the app to crashing immediately. I assumed it was because of context issues between node.js and the node-webkit browser, but those seem to not be at fault since I tried this suggestion to make sure it finds the correct file for the marked module...went right back to immediate crashing. I'm out of ideas because the crashes don't seem to leave me any way of knowing what the error was.
