• Gaining application/module context from a symfony task

  - by Martin Chatterton

  I have written a reporting suite, and I have a specific report that builds a CSV file. Serving this file via a browser on demand isn't an issue, but I need to be able to build this CSV file nightly, and email round a link to be able to download it. Essentially, I need to be able to replace a specific action with a symfony task, run via cron. So how do I gain application/module context from a symfony task? And secondly, how would I invoke the SwiftMailer library from a symfony task? I'm using symfony v1.4.4 and PHP v.5.2.13. Thanks in advance for your help.

• Use of WebDAV to access OWA (exchange 2003) mails with Basic authentication and SSL

  - by Mayuresh

  I have got a working C# code for accessing OWA mails using WebDAV against a FBA enabled exchange 2003 (http://support.microsoft.com/kb/891748/en-us/) But my client's OWA (exchange 2003) has Basic authentication and SSL (i-e when I try to access the web mail link through browser I get a grey login box instead of a web page I can log into the mail box once I enter the correct details) But my same fails with a 401 error against this mailbox. I got the simple request working for the Basic authentication using – String usernamePassword = strUserName + ":" + strPassword; WebReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword))); But the subsequent WebDAV SEARCH request fails with 404 (resource not found) error. Can we use WebDAV against an exchange 2k3 with SSL and Basic authentication?

• Need a Javascript Expert, IE slow script

  - by Aaron Carlino

  I have a jQuery plugin running on my site that is executing very, very slowly in IE7/8 to the point that it throws a slow script warning to the user. It doesn't happen in any other browser, and I can't figure out what might be going on. If you go to this page: http://dev.xeetic.org/projects You'll see that there are 16 results on each page, and each one has a "flip" behavior attached, using the jQuery plugin "quickflip." Attaching this behavior is very slow in IE. If I reduce the result set to 8 or 4 per page, it's faster, but still very bogged down. I have contacted the author of the script with no success. I am willing to pay for a solution, if I'm allowed to offer such a thing on this site. Very desperate. Please help!

• Setting a Global Doctype

  - by Batfan

  Is it possible using PHP (I was thinking may the phpinfo file or a php.ini file) or an .htaccess file to set a doctype for an entire subdirectory? Basically, in a nutshell, I'm using a software that uses XSL templates to output data to a set of HTML files. Modifying the xsl:output tag to include the doctype breaks the template and therefore, does not work. Just adding the doctype in the XSL file, breaks it as well. I need the proper doctypes in place for my CSS to function properly, cross-browser. I realize that I could add the doctype to the HTML files after export but, I'm really striving to automate this process. Any thoughts?

• Is there a better way to do SELECT queries in MySQL and sort them in PHP than this way?

  - by Kent

  I am just learning PHP/MySQL, one this I am having to do a lot is displaying data that was previously inserted into the database out to the user's browser. So I am doing this: $select = mysql_query('SELECT * FROM pages'); while ($return = mysql_fetch_assoc($select)) { $title = $return['title']; $author = $return['author']; $content = $return['content']; } then I can use these variables through out the page. Now, doing it the above way isn't an issue when I only have 3 columns in a database but what if I am dealing with a huge database with many more columns. I have a nagging feeling that the pros do it in some more efficient way where they maybe loop through the table they are selecting from to find all columns it has and associate them with variables automatically. Is that the case? or is the above how you guys do it too?

• jQuery way to handle select lists, radio buttons and checkboxes

  - by Álvaro G. Vicario

  When I handle HTML form elements with jQuery, I always end up with an ugly mix of jQuery syntax and plain JavaScript like, e.g.: function doStuff($combo){ if( $combo.get(0).options[$combo.get(0).selectedIndex].value=="" ){ var txt = ""; }else{ var txt = $combo.get(0).options[$combo.get(0).selectedIndex].text; } var $description = $combo.closest("div.item").find("input[name$=\[description\]]"); $description.val(txt); } Are there standard jQuery methods to handle typical operations on elements like <select>, <input type="radio"> and <input type="checkbox">? With typical, I mean stuff like reading the value of the selected radio button in a group or replacing elements in a selection list. I haven't found them in the documentation but I admit that method overloading can make doc browser kind of tricky.

• Node.JS Server Cuts Off Frequently?

  - by aherrick

  I have a Node JS Server where I am using Socket.IO to stream content to the browser. It works great for about 45 minutes or so of streaming, then it will usually cut out. There are no "errors" reported in the terminal and the Node server acts like it is in, however the page I am serving clearly stops working. What are my options for trying to get to the bottom of this? Could this be a configuration issue with Node/Socket.IO? is there any basic error logging you would recommend I setup?

• Launching a Facebook page from an iPhone app via QR code

  - by user1655186

  I'm trying to create a QR code that launches a Facebook page from the app, rather than the browser on both Android and iOS. Creating the code with fb://page/<page id>, works perfectly on an Android. This was also supposed to work with iOS's Facebook app, but I think since Facebook updated their app recently from a HTML5 version to a fully native iOS app, that functionality has stopped working. It indeed opens the Facebook app, but it does not go to the page. Has anyone else seen this happen since the app was updated a few weeks ago? And what string would I have to use to create a working QR Code for iOS's Facebook app?

• jQuery get request against Sinatra does not get text

  - by jerhinesmith

  I have a very simple sinatra site that I'm trying to access via ajax through jQuery. To keep things incredibly simple, this code snippet: get '/behavior_count' do "60" end which returns "60" in the browser, shows up as an empty string when attempting to access the site via $.get in jQuery. The strange part is in Firebug, while the Response is empty, the HTTP header correctly describes Content-Length as 2, and I can see the request show up on the server. Is there something specific to Sinatra that isn't returning my data, or am I not using jQuery correctly? If it helps, I also tried this code: get '/behavior_count' do content_type 'text/plain', :charset => 'utf-8' "60" end and my jQuery looks like $.get('http://mysite:4567/behavior_count'); // Ignore the response, but // watch the request in firebug Any ideas?

• Can not make a request to google map

  - by Eme Emertana

  Hi I am making a restful request to google map, but I run into following error; java.io.IOException: Server returned HTTP response code: 400 for URL: http://maps.googleapis.com/maps/api/distancematrix/xml?origins=Washington, DC USA&destinations=Los+Angeles+CA+USA&mode=driving&sensor=false at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1436) at java.net.URLConnection.getContent(URLConnection.java:688) I believe its making a correct connection as I can get the correct response by copying the above URL into my browser, I am wondering why I am getting 400 error code in my console and I dont get the correct response when java is sending the request.

• Seeking not working in HTML5 audio tag

  - by lord_wilmore

  I have a lighttpd server running locally. If I load a static file on the server (through an html5 audio tag), it plays and seeks fine. However, seeking doesn't work when running a dev server (web.py/CherryPy) or if I return the bytes via a defined action url instead of as a static file. It won't load the duration either. According to the "HTTP byte range requests" section in this Opera Page it's something to do with support for byte range requests/partial content responses. The content is treated as streaming instead. What I don't understand is: If the browser has the whole file downloaded surely it can display the duration, and surely it can seek. What I need to do on the web server to enable byte range requests (for non-static urls). Any advice would be most gratefully received.

• Zend + Wamp = Cant use curl/fput for a url locally

  - by bluedaniel

  Ive got a page in Zend all set up that will for now just echo "Hello", this address is at http://dev.local/hello and works when visiting in the browser. However when I try to use curl or file_get_contents from a script in my zend 'public' folder I get a 500 Internal error message. UPDATE Its failing because my application tries to set the langauge based on the browsers default language, when using headers like I have below, how do I add this locale? "User-Agent: XXXXXXX/2.0\r\n" . "Accept: */*\r\n" . "Accept-Charset: utf-8;\r\n" .

• Notepad++ Question

  - by Shane

  I would like a hotkey to Save All in Notepad++ then switch to the browser and refresh the page. I have to do this thousands of times a day and doing the Save All hotkey, then Alt-Tab to the right window, then F5 to refresh again and again, there must be a better solution? I am open to switching editors if there is another that can do this. I have tried using run commands but the problem is although it allows you to make something like [firefox.exe "current file"], if you come down to wanting to open it at a web address like localhost because it needs to run server side, then you have to manually specify the other part of the string, like [chrome.exe "custom var(web address) / filename"] and it always opens a new tab, then creates lots of clutter. Also, if you are editing an include file then it will try to open that instead of the page you want to see when you use the run command, a refresh would be the only realistic method I can think of using.

• Force reload/refresh when pressing the back button

  - by FlyingCat

  I will try my best to explain this. I have an application that show the 50+ projects in my view page. The user can click the individual project and go to the update page to update the project information. Everything works fine except that after user finish updating the individual project information and hit 'back' button on the browser to the previous view page. The old project information (before update) is still there. The user has to hit refresh to see the updated information. It not that bad, but I wish to provide better user experience. Any idea to fix this? Thanks a lot.

• Pre-cache site as user visits

  - by strager

  I am making a static site which is 'forced' to be cached via Cache-control, etc. When a user visits my site, I want the browser to crawl my site, caching pages, so when the user navigates to a page, the load is almost instant. (I do not need a recursive crawl, as that will probably happen as the user navigates between pages. I just need to crawl the links on the current page, and of course not re-caching a page which has already been cached.) (Also, I am not changing pages using Ajax-like techniques. These are essentially normal flat HTML files with normal links.) How can I do this pre-caching using Javascript? (I am using jQuery.)

• Tree View / File View Control for C#

(If anybody can clear that up for me, I would like that even better.) Thanks for any help.

• Navigation Dropdown Text Color doesn't work in FF and IE

  - by Genadinik

  Hello, I was able to get the navigation dropdown to show the letters in a different color from the background (white in this case) in Chrome browser. But when I view the same page in IE or FF, the whole background is just all green. Here is an example of such a page: http://www.comehike.com/hikes/hikes_and_groups.php And here is the CSS code that makes the color show up white in Chrome navigation li li a {color:#white; text-decoration:none;} To see the difference, just mouse over the top right where it says "community" or "hikes" Thanks, Alex

• Huge framerate difference between Test and Publish movie in Flash?

  - by Glacius

  Simply put, I am making a flash midi player. I am using ENTER_FRAME for my timings. I set the framerate to 100 to ensure that the timing of each note in milliseconds is accurate. When I test the movie with CTRL + ENTER it works fine. When I publish it and open it in a browser (tested both IE and Chrome), it suddenly plays back a lot slower. I don't think it's a performance issue, since the code is very simple. If this slowdown is consistent then I can perhaps work with it so that the playback speed will be correct. Do browsers make the framerate slower or do they implement a framerate cap of some sort? What is going on?

• select subquery cause mysql server to be unresponsive

  - by Xiao

  DELETE FROM item_measurement WHERE measurement_id IN ( SELECT (-id) AS measurement_id FROM invoice_item WHERE invoice_id = 'A3722' ) I've really tried hard to find what's wrong with the code. I tried to run this in a php page, which doesn't respond. I also tried the same line in phpmyadmin, infinite spinning circle and I had to restart the server(MAMP on Mac 10.9). No error was given in browser/ If I run the delete and select separately, they both finish very quickly. I don't think it's a performance issue because the separate run took < 0.1 sec each. Thanks for any help in advance. Edit: I also found that a simple select statement will also suspend mysql: select * from item_measurement where measurement_id in (select -id from invoice_item where invoice_id='A3722')

  hello to all, my client wants to play a flash video in their website. just to make sure i understand correctly, i need to: 1. create an FLV file 2. use either some flv player or wrap the flv inside swf questions: 1. the player option - will visitor have to download /install it or is it install only once, in the website itself? any FREE player you can recommend the will ensure cross browser compatibility? swf option: will i need the flash application in order to do the wrapping? will i be able to later use something like flashobject library for the actual embedding? what are the main considerations for choosing between the two options , if indeed these are the options? any help would be highly appreciated. have a nice day and let's pray for a lot of goals today :-)

• HTTP Download very Big File

  - by Luca

  I'm working at a web application in Python/Twisted. I want the user to be able to download a very big file ( 100 Mb). I don't want to load all the file in memory (of the server), of course. server side I have this idea: ... request.setHeader('Content-Type', 'text/plain') fp = open(fileName, 'rb') try: r = None while r != '': r = fp.read(1024) request.write(r) finally: fp.close() request.finish() I expected this to work, but I have problems: I'm testing with FF... It seems the browser make me wait until the file is completed downloaded, and then I have the open/save dialog box. I expected the dialog box immediately, and then the progress bar in action... Maybe I have to add something in the Http header... Something like the size of the file?

• Using a JSON web service from a Java client application

  - by user383341

  I am developing a client-side Java application that has a bit of functionality that requires getting data from some web services that transmit in JSON (some RESTful, some not). No JavaScript, no web browser, just a plain JAR file that will run locally with Swing for the GUI. This is not a new or unique problem; surely there must be some open source libraries out there that will handle the JSON data transmission over HTTP. I've already found some that will parse JSON, but I'm having trouble finding any that will handle the HTTP communication to consume the JSON web service. So far I've found Apache Axis2 apparently which might have at least part of the solution, but I don't see enough documentation for it to know if it will do what I need, or how to use it. Maybe part of the problem is that I don't have experience with web services so I'm not able to know a solution when I see it. I hope some of you can point me in the right direction. Examples would be helpful.

• Playback audio data with GWT

  - by Henrik

  I am creating a GWT client application which interacts with a server and I am getting all my response data from the server in JSON format. Amongst others there are wave data on the server's database which I would like to retrieve and then playback on the client. I am able to get the wave data as an array of bytes in the JSON format. My problem is, how do I playback the wave array data in a browser? Is it even possible or do I have to find another solution? I've searched the web and found some GWT packages which are able to playback sound, but they are all playing back directly from an url.

• How to Prevent an Applet from Unloading across web pages?

  - by Francis Shanahan

  I have a large applet that takes some 40 seconds to initialize (cabs are cached so ignore download time for this question). The issue is, if the user goes to Page A which launches the applet (single window) and then navigates to page B, the applet is unloaded. If the user goes back to Page A, they incur the 40 seconds init time once again. I'd like to be able to launch the applet, incurring the 40 seconds init time once and only once. The applet needs to reside inside a single browser window (the same window as my web application). In other words, I cannot launch the applet in a popup. Does anyone have any creative ideas around how to prevent the applet unloading?
