• Uploadify refuses to upload WMV, FLV and MP4 files - SOLVED

  - by Jon Winstanley

  The uploadify plugin for JQuery seems very good and works for most file types. However, it allows me to upload all file types apart from the ones I need! Namely .WMV, .FLV and .MP4 Uploads of any other type work. I have already tried changing the fileExt parameter and also tried removing it altogether. I have testing in Google Chrome, IE7 and Firefox and none work for these file types. I have a ton of local projects already and uploading is not an issue on any other project, I even use the same example files (This is the first time I have used Uploadify) Is there a known reason for this behaviour? EDIT: Have found the issue. I had forgotten to add my usual .htaccess file to the example project.

• Socket Communication in C#- IP-Port

  - by Ahmet Altun

  I am testing my socket programs at home, in local network. Server and client programs are running on seperate machines. Server program socket is binded as: serverSocket.Bind(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8999)); Client program (on the other computer) is connected as: clientSocket.Connect(IPAddress.Parse("192.168.2.3"), 8999); Why can Client not communicate with server? Do I need to make some firewall configuration or something like that? Or am I writing Server Ip incorrectly to the Client? (I got it from cmd-ipconfig of server)

• Colgroup in ffox/chrome

  - by Razor

  I am testing the <colgroup> tag on a 5 columns table, with a style attribute. I can't seem to make it work on firefox 3.6/chrome 5 tho, and this is when I started searching for the reference on w3c. It seemed like my code was perfectly fine, but looking at the w3c editor I noticed not even that was working. Only IE8 seems to work correctly, opera 10.51 ignores the style tag but applies the align tag correctly, while ffox and chrome seems to ignore colgroup completely. So what am I (and w3c) doing wrong? Was colgroup deprecated and I missed it?

• NHybernate, the Parallel Framework, and SQL Server

  - by andy

  hey guys, we have a loop that: 1.Loops over several thousand xml files. Altogether we're parsing millions of "user" nodes. 2.In each iteration we parse a "user" xml, do custom deserialization 3.finally, in each iteration, we send our object to nhibernate for saving. We use: .SaveOrUpdateAndFlush(user); This is a lengthy process, and we thought it would be a perfect candidate for testing out the .NET 4.0 Parallel libraries. So we wrapped the loop in a: Parallel.ForEach(); After doing this, we start getting "random" Timeout Exceptions from SQL Server, and finally, after leaving it running all night, OutOfMemory unhandled exceptions. I haven't done deep debugging on this yet, but what do you guys think. Is this simply a limitation of SQL Server, or could it be our NHibernate setup, or what? cheers andy

• HTML 5 offline caching

  - by kRON

  I've read the following Mozilla Developer article that explains how to implement HTML 5 offline resource caching in web apps. I've tried testing this locally: added the mime type to the list, created the manifest file, changed my doctype to the HTML 5 doctype, specified the manifest attribute and the correct path on the HTML element--but still I don't see the manifest file being consumed by Firefox at all. I've also checked the access logs on Apache and didn't see any requests for the manifest file being made. Has anyone given it a jab and had any success? I just don't know how to further troubleshoot the issue and would welcome any suggestions.

• Carrier Wave not completing upload to Rackspace Cloud Files

  - by Zack Fernandes

  Hello, I have been attempting to get file uploads to Rackspace Cloud Files online all night, and finally tried the Carrierwave Plugin. Although the plugin worked right away, when I tried viewing the file uploaded (an image) it was broken. Upon further testing, I found out that files would upload to Cloud Files, however were just a fraction of their original size. I can't seem to figure out what's worng, and any help would be greatly appreciated. My code is as follows. models\attachment.rb class Attachment < ActiveRecord::Base attr_accessible :title, :user_id, :file, :remote_file_url, :file_cache, :remove_file belongs_to :user mount_uploader :file, AttachmentUploader end uploaders\attachment_uploader.rb class AttachmentUploader < CarrierWave::Uploader::Base storage :cloud_files def store_dir "#{model.user_id}-#{model.id}" end end

• ASP.NET Asynchronous Tasks - Worker Thread Not Releasing?

  - by user296752

  I am having an issue with testing asynchronous tasks in ASP.NET & IIS7. From what I have read, the worker thread should be released back into the thread pool while the I/O thread performs the async work, allowing ASP.NET to server other incoming requests. But when I simulate heavy load on the web application by making 20 simultaneous requests to a page (async.aspx) that performs long running async tasks, I am unable to browse to some other normal aspx page until the requests are just about done. Am I misunderstanding or missing something here? I am running Vista Biz x64, VS2008 + IIS7. I have the Async attribute applied to the Page directive.

• groovy thread for urls

  - by Srinath

  I wrote logic for testing urls using threads. This works good for less number of urls and failing with more than 400 urls to check . class URL extends Thread{ def valid def url URL( url ) { this.url = url } void run() { try { def connection = url.toURL().openConnection() connection.setConnectTimeout(10000) if(connection.responseCode == 200 ){ valid = Boolean.TRUE }else{ valid = Boolean.FALSE } } catch ( Exception e ) { valid = Boolean.FALSE } } } def threads = []; urls.each { ur - def reader = new URL(ur) reader.start() threads.add(reader); } while (threads.size() 0) { for(int i =0; i < threads.size();i++) { def tr = threads.get(i); if (!tr.isAlive()) { if(tr.valid == true){ threads.remove(i); i--; }else{ threads.remove(i); i--; } } } Could any one please tell me how to optimize the logic and where i was going wrong . thanks in advance.

• How do I catch jQuery $.getJSON (or $.ajax with datatype set to 'jsonp') error when using JSONP?

  - by Andy May

  Is it possible to catch an error when using JSONP with jQuery? I've tried both the $.getJSON and $.ajax methods but neither will catch the 404 error I'm testing. Here is what I've tried (keep in mind that these all work successfully, but I want to handle the case when it fails): jQuery.ajax({ type: "GET", url: handlerURL, dataType: "jsonp", success: function(results){ alert("Success!"); }, error: function(XMLHttpRequest, textStatus, errorThrown){ alert("Error"); } }); And also: jQuery.getJSON(handlerURL + "&callback=?", function(jsonResult){ alert("Success!"); }); I've also tried adding the $.ajaxError but that didn't work either: jQuery(document).ajaxError(function(event, request, settings){ alert("Error"); }); Thanks in advance for any replies!

• Getting website data into Adobe InDesign

  - by Magnus Smith

  I'd like our magazine team to be able to download website data in a file that Adobe InDesign can read. They can then import/open the file, make a few tweaks, and cut out a vast deal of repetitive manual labour (they currently use copy&paste for a few hours). After a brief Google I note that v2 of InDesign can import/export XML so perhaps that is my best bet? Are there any alternatives, and can anyone offer any advice on them? I am using a PC, and the magazine team are on Macs; testing will be tiresome I fear. The data we wish to format is fairly simple - a title followed by a short chunk of text (repeated about 50 times, say). I'll ask about importing images later. Thanks for your help. I will return to Google now, but it would be great if anyone can point me in a more specific direction first!

• How to sync with eclipse target management?

  - by SpliFF

  I've been using the Jcraft SFTP plugin for Team Synchronisation up till now but I ran across a rumour it's being deprecated by "Target Management". Still, despite my best efforts I haven't found any information on HOW you are supposed to setup a sync with RSE/Target Management. Can anybody provide a step-by-step guide or at least clarification on whether this is actually possible right now or just a planned feature. I do my testing locally then sync to the remote - which may have changes made by other users. I want to be able to see differences and deal with conflicts etc just like with the current Team Synchronization framework.

• Phonegap: Slow response with vibrate notification

  - by jjei

  I created a simple android application with jquery and phonegap. When testing the app with phone, I noticed that vibration effect, that I have used to indicate that user touches a button, comes after a delay of maybe 0,5 seconds. This is way too long delay and just confuses the user. Is this just the downside of using phonegap? Or is there any configuration or additional frameworks which could be used to make the app response and produce the vibration more quickly? I installed the vibration plugin like this: phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-vibration.git I use the code below to create the vibration effect. navigator.notification.vibrate(200); My phone gap version is 3.0.0-0.14.3

• sproutcore - todos tutorial, addbutton not responding in firefox

  - by kristian nissen

  I'm testing the sproutcore todo's tutorial and I have checked the code in step-5 and it's identical to my code at least as far as I can see, but the addButton is not responding to click events. addTask: function () { var task; task = Sinatra.store.createRecord(Sinatra.Task, { 'description': 'New Task', 'isDone': false, 'priority': 1 }); this.selectObject(task); this.invokeLater(function () { var contentIndex = this.indexOf(task); var list = Sinatra.mainPage.getPath('mainPane.middleView.contentView') var listItem = list.itemViewForContentIndex(contentIndex); listItem.beginEditing(); }); return YES; and in the main: addButton: SC.ButtonView.design({ layout: { centerY: 0, height: 24, right: 12, width: 100 }, title: 'Add Task', target: 'Sinatra.tasksController', action: 'addTask' }), I can't see the problem, please help. (I have only tested this in firefox on kubuntu)

• linking to an app on the Itunes store

  - by William Jockusch

  A few web searches yield all sorts of contradictory advice on linking from an iPhone app to an app on the store. Here are some links that come up, together with comments from testing: http://itunes.apple.com/us/app/anagramania/id360016055?mt=8 -- works great. But is it US only? "http://itunes.com/apps/anagramania" -- works after a bunch of redirects, which are likely to annoy the customer. @"http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=360016055&mt=8"]; -- works great. But Apple appears to be trying to remove "phobos" links from its documentation. @"http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=360016055&mt=8"]; -- works great, but Apple's documentation mentions problems with similar links. Apple doc here: http://developer.apple.com/iphone/library/qa/qa2008/qa1633.html#STANDARD_APPSTORE_LINKS Can anyone bring order out of this chaos?

• WAMP Server not working

  - by Jeremy Rudd

  Okay so a continuation from this question, where you experts intro'd me to WAMP, which can basically execute PHP within a Windows XP environment. So now I've got it installed, but the tray icon forever shows YELLOW, and when I visit any PHP page in my browser, it just shows me the PHP source! Also, when I visit "http://localhost/" in IE7 it gives me a 404 Not Found, FF3 just shows a blank page. BTW I've tried "Restart All Services" and restarting my machine, but it still won't work. Any ideas? Any of you had this problem and solved it? Please help me here, I'm desperate to execute PHP client-side and I'm just reverting to testing on-server for now!

• How to run unit tests with DSSS and GDC?

  - by Benoit Vidis

  I am very new to D and still battling trying to configure my toolchain. I am running Ubuntu Karmic and would like to use DSSS with GDC and Tango or TangoBos. Till now, I installed GDC from Ubuntu repositories, DSSS, Tango and TangoBos from these repositories and I can compile using dsss + gdc + tangobos. According to DSSS documentation, it should be possible to run the unit tests using $ dsss build --test but on my system, the --test argument is ignored. I have dsss last version (0.78) and its inline help does not include anything about unit tests. Running ldc --unittest works fine (though I do not know exactly which libray it picks up). Is there a way to run my unit tests using the same compiler & library than for compilation? If so, is there a way to automate the testing or will I have to run it module per module?

• How to prevent multiple browser windows from sharing the same session in asp.net.

  - by Barry

  I have ASP.net application that is basically a data entry screen for a physical inspection process. The users want to be able to have multiple browser windows open and enter data from multiple inspections concurrently. At first I was using cookie based sessions, and obviously this blew up. I switched to using cookie-less sessions, which stores the session in the URL and in testing this seemed to resolve the problem. Each browser window/tab had a different session ID, and data entered in one did not clobber data entered in the other. However my users are more efficient at breaking things than I expected and it seems that they're still managing to get the same session between browsers sometimes. I think that they're copying/pasting the address from one tab to the other in order to open the application, but I haven't been able to verify this yet (they're at another location so I can't easily ask them). Other than telling them don't copy and paste, or convince them to only enter one at a time, how can I prevent this situation from occurring?

• managing library dependencies with Boost.Build and C++

  - by user931794

  I want to develop a project which can be built on a bunch of different platforms. The project code will be in C++, what's the the best way to manage libraries? I plan on using bjam as the build system because I'm going to be depending on Boost and their unit testing framework as well. The two dependent libraries are Boost itself and FLTK. The possibilities that come to mind for library management are: include build artifacts (binaries) and headers for all supported platforms in-tree include complete source for all dependent libraries in-tree, and somehow script them as dependencies A combination of 1 and 2, like node.js does with v8 inform the user that they need to build the libraries themselves and then have them on the PATH or in some special directory, like libcurl does with its dependencies What is the best approach here? The project will probably not grow beyond a few thousand lines over the next six months, but I want to make the right choice here so that I don't have to come back and switch everything around later.

• IronPython/C# Float data comparison

  - by Gopalakrishnan Subramani

  We have WPF based application using Prism Framework. We have embedded IronPython and using Python Unit Test framework to automate our application GUI testing. It works very well. We have difficulties in comparing two float numbers. Example class MyClass { public object Value { get; set;} public MyClass() { Value = (float) 12.345; } } In IronPython When I compare the MyClass Instance's Value property with python float value(12.345), it says it doesn't equal This statement raises assert error self.assertEqual(myClassInstance.Value, 12.345) This statement works fine. self.assertEqual(float(myClassInstance.Value.ToString()), 12.345) When I check the type of the type(myClassInstance.Value), it returns Single in Python where as type(12.345) returns float. How to handle the C# float to Python comparison without explicit conversions?

• What's the best BDD framework for working with ASP.NET MVC 2 + C# 4?

  - by Soul_Master

  I just heard about BDD when I watch video of Scott Guthrie in Sweden. One of listener asked question to Scott about How VS2010 and ASP.NET MVC do to support BDD. After that, I search about BDD (Behavior Driven Development) that focus on specification more than unit testing when compares with TDD (Test Driven Development). I found some framework that work with Ruby and Java. But I do not any famous framework for .NET. Please suggest me about BDD framework and summary PROs/CONs of it. PS. Suggested BDD framework must work great on .NET 4, C# 4.0 and ASP.NET MVC 2. Thanks,

• Is there any simple way to test two PNGs for equality?

  - by Mason Wheeler

  I've got a bunch of PNG images, and I'm looking for a way to identify duplicates. By duplicates I mean, specifically, two PNG files whose uncompressed image data are identical, not necessarily whose files are identical. This means I can't do something simple like compare CRC hash values. I figure this can actually be done reliably since PNGs use lossless compression, but I'm worried about speed. I know I can winnow things down a little by testing for equal dimensions first, but when it comes time to actually compare the images against each other, is there any way to do it reasonably efficiently? (ie. faster than the "double-for-loop checking pixel values against each other" brute-force method?)

• How can I detect if the browser has encountered a JavaScript error ... in JavaScript?

  - by RichH

  For automated testing reasons I want to detect if the browser has encountered JavaScript errors for a page. The type of things that would cause the red numbers in the bottom right in Firebug or yellow warning icon in the Internet Explorer status bar. These JS errors could come from any one of a large numbers of scripts. How in JavaScript can I detect these browser errors? Cross browser solutions prefered, but hey, I'll take anything! As a bonus it would also be great to know the script that caused the error.

• Unable to save to wincache from cakePHP shell

  - by Phillaf

  I'm trying to retrieve the weather from wunderground.com through their API, and store it in wincache. For testing purposes I made this function in the News model: public function updateWeather(){ $results = file_get_contents('http://api.wunderground.com/api/**api_key**/conditions/q/CA/Montreal.json'); $results = json_decode($results); return Cache::write('weather', $results); } It works fine when I call this from the controller. However, I can't figure why that same function doesn't work when called from the console. I made this shell in order to eventually add this to windows task scheduler. class WeatherShell extends AppShell { public $uses = array('News'); public function main() { $this->News->updateWeather(); } } When running this, I see that $results is correctly populated. I get 'true' from Cache::write(), however, I get 'false' when trying to read. What subtlety am I missing?

• How to paint background of specific range of text in NSTextView

  - by Rui Pacheco

  Hi, This is not a specific bug, its more about not knowing how to do something. I've an NSTextView and I need to paint the background of specific ranges of text when the user clicks on a specific part of the text view. I've tried this but I just get erratic behaviour in the sense that sometimes text loses the foreground color or the background doesn't span the whole range: NSLayoutManager *layoutManager = [myTextView layoutManager]; [layoutManager removeTemporaryAttribute:NSBackgroundColorAttributeName forCharacterRange:range]; [[myTextView layoutManager] setTemporaryAttributes:attributes forCharacterRange:range]; For the sake of simplicity assume that range is always a valid string (it is in my testing environment).
