• FMS: Stream.play on server side makes video choppy

  - by Tinelise

  I have an *.flv file on a FMS. When I play it on the client side the video plays just fine, but when I call Stream.play(filename, 0, -1, false) on the server side the video turns out really choppy. I both cases I use NetConnection to connect to an rtmp and NetStream to play the stream, but in one case I connect to a stream and request the server to play my file on that stream. Apparently that doesn't work with files? It works just fine for live streams. I really don't get why this should differ at all. Any suggestions?

• Why can't I play videos on my Samsung Moment w/Android 2.1 that did play on 1.5?

  - by cpcarroll71

  Hello all. I was directed here by the Google Android Devs Group. I'm still not sure if this is the place I need to be. I've been on forum after forum and asked the same question but no one seems to know the answer or will tell me the REAL correct place to find it. I have a Samsung Moment with Android 2.1. I can not get videos that DID play on Android 1.5 to play on 2.1 now with very few exceptions. I'm not just talking about different videos with the same format, I'm talking about some of the exact same videos that did play in 1.5 will no longer play in 2.1. These are almost all AVI files. If Android doesn't support AVI natively with it's own stock media player then why or how was I able to play these videos flawlessly on 1.5? The way I always played the videos was viewing my SD card, tapping the thumbnail of the video I wanted, and it would automatically open up in the phones media player right away. Now the phone locks up and then eventually gives an error message. Please tell me someone here knows what is going on and if there is a way to fix this. Or if nothing else, tell me where I do need to look to ask this question and find an answer. Thank you.

• How can I make my Video play as soon as the page loads

  - by bill

  im lost here, need some help for something probably very simple: I have embedded a swf object to play an flv file. i want the video to play as soon as the page loads rather than requiring the viewer/user to have to click the play button to see the video. I'm not sure if it is the swf file, the script or the javascipt file that has to be edited, and with what code. thanks

• Play/pause HTML 5 video using JQuery

  - by Barny83

  I am trying to control HTML5 videos using JQuery. I have two clips in a tabbed interface, there are six tabs in total, the others just have images. I am trying to make the video clips play when their tab is clicked and then stop when any of the others are clicked. This must be a simple thing to do but I cant seem to get it to work, the code I am using to play the video is: $('#playMovie1').click(function(){ $('#movie1').play(); }); I have read that the video element needs to be exposed in a function to be able to control it but can't find an example. I am able to make it work using JS: document.getElementById('movie1').play(); Any advice would be great. Thanks

• My Western Digital 500GB Passport disk says "not formatted" when I plug it in Windows

  - by learnerforever

  Hi, When I plug my Western Digital 500 GB Passport disk in my Windows machine, it says "not formatted, do you want to format it" something. I started having this problem after I put it in an old desktop at home. I don't exactly know what went wrong. May be partition table is corrupted etc. Questions: Some quick search on internet tells me there are partition fixing utilities, which can fix corrupted partition table. testdisk being one of such utiities. I can understand how to use this to copy files from the disk to some other location, but I would like to fix the partition table in-place so that I don't have to temporary move around my data of approx size 300GB, then format passport disk and then again bring back the data. Is there any way I can fix the partition table in-place? Also, how to know which file system was there originally in the disk? Can I only keep the same file system? My current laptop is running Windows 7. Earlier I used to use Windows Vista. My other laptop has Windows XP. So I have access to Windows 7 and Windows XP. Please help! Thanks,

• Plug-in device to front USB computer *sometimes* restarts

  - by Mark A. Nicolosi

  I've got a strange problem that very occasionally (maybe once a month) when I plug-in something to the front USB on my computer, the computer suddently restarts. This also happens when I touch the front USB ports sometimes. This has been going on for a few years and a lot of the components in my PC have changed. I thought it was my home wiring, but I moved last year and it still happened. I thought maybe it was the motherboard, but that was upgraded 9 months ago and it still happens. I thought it was my case, but I changed that recently and it still happens. I thought maybe it was my PSU, but I upgraded that yesterday and it still happens. I'm pretty sure this is an electro-static thing, but I thought that modern computers have protection against this sort of thing. Maybe I should move my case off the floor (carpet) and stop wearing songs all the time. Edit: Just to clarify this is a computer that I built. The components have been upgraded throughout the years and it's not much the same computer anymore. This doesn't happen very often, but it is annoying, because I don't know what the cause is. Anyone have any ideas?

• Play Halo on the Xbox360 Arcade

  - by Jeremy Rudd

  I'm looking at purchasing a Xbox360 because I've wanted to catch up with the Halo trilogy. Does the cheap Arcade edition console support Halo 2 Halo 3? Halo Wars? Would I be able to save my game progress in single player? Would I be able to play online in typical maps? General questions: Would I be able to play games using the DVD drive or do I have to download everything? Does the tiny HDD hurt even if I don't download any games, trailers or music? Are there any other differences in comparison to the Xbox360 Pro? I have a regular TV that uses the composite cable, so I don't need the HDTV support in the Pro edition.

• Why can't I play YouTube clips properly anymore?

  - by NoCanDo

  I haven't got the faintest idea what happened, but since about 3-4 days now I can't play any clips on YouTube properly at all. Proper as in continuously without loading, pause, playback, pause, loading, playback, pause, loading, playback, etc. I haven't changed anything hardware nor software-wise. On the other hand I can play Break.com, Viddler, Liveleak, Metacafe without any trouble. I tried my own tips, but that hasn't helped me at all. What on earth happend? Is it me, or is it YouTube? I'm using Firefox 3.6 Beta 5. But the issue is the same on Chrome as well as on Internet Explorer.

• DVD Drive can read a DVD title and file contents (very slowly) but not play DVDs

  - by Daisetsu

  I've been able to watch DVDs in the past on this computer when it was running XP. I recently upgraded to windows 7 and haven't watched a DVD since then. I put a DVD in and it took quite a long time but windows finally found the disk title, and I was able to explore directories (saw folder like VIDEO_TS). The problem is when I try to have video players play the DVD I just get an error in VLC. It wouldn't tell me the exact error (said to check the log and I don't know where that is). Do I have to install some special drivers/certs in windows 7 to play video?

• Linux Live CD cannot play video

  - by lamwaiman1988

  I want to switch from windows to linux, but before the switch I would like to try them out in the Live CD. I downloaded the iso and created a multiboot usb stick ( by YUMI Multiboot USB Creator ). I can boot into Ubuntu Desktop 12.04 64 bit LTS and Linux Mint 13 Mate 64 bit. I can access the hard drive from there and I tried some video with the default player comes with them ( e.g: GNOME Player and VLC Player ). The player opened but the video didn't play. However, I can play the same video in Puppy Linux. ( Puppy Linux doesn't has a choice over 32-bit or 64-bit ) Maybe my CPU didn't support 64 bit? Here is a snap from CPUZ: CPU: AMD Phenom II X3 710

• PC does not recognize XBox 360 controller connected through Play & Charge Kit

  - by Mike Cole

  I wanted to hook up my wireless XBox 360 controller to my PC running windows 7. I'm trying to use the Play & Charge kit since I already had that laying around. I plugged it in and Windows recognize it and installed it. It registers in Device Manager as "Xbox 360 Wireless Controller via Play & Charge Kit". The controller also has the 1st quadrant lit. However, I can't seem to make this work with any games. I installed the "Microsoft Xbox 360 Accessories" kit from MS website, and I run the Accessories Status app and it doesn't recognize that the controller is connected. Does anybody know what I'm doing wrong out there?

• Play a Complete HTML5 Version of Super Mario Bros. Online for Free

  - by Akemi Iwaya

  If you love playing Super Mario Brothers, but hate the hassle of dealing with or setting up the game console, then you will be pleased to know a new and complete version is now available to play online. Josh Goldberg has worked hard to recreate the classic game in its entirety in HTML5, so sit back, relax, and get ready to enjoy all that Mario goodness via your favorite browser. There are three ‘modes’ of game play available: play through reproductions of the original classic levels, test yourself against randomly generated levels, or use the level editor to create custom levels. Special Note: There are two online versions available…one for playing in Google Chrome and one for playing in all other browsers. For our example we chose to use the non-Chrome version.

• Excel Plug-In Assembly Loading Problem (Access Denied)

  - by PlagueEditor

  I am developing an Excel 2003 add-in using Visual Studio 2008. My add-in loads fine; however, it loads plug-ins from other C# DLL's. I would like this to be done dynamically at run time so referencing them during development is something I would rather not do. Anyways, anytime I try to load a DLL from the Excel add-in at start up, it throws a security exception. This particular example is HTML Agility Pack. It's not a plug-in but a plug-in's dependency. But nonetheless it won't even load: {System.IO.FileLoadException: Could not load file or assembly 'HtmlAgilityPack, Version=1.4.0.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418) File name: 'HtmlAgilityPack, Version=1.4.0.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' ---> System.Security.Policy.PolicyException: Execution permission cannot be acquired. at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Boolean checkExecutionPermission) at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Int32& securitySpecialFlags, Boolean checkExecutionPermission) at System.Reflection.Assembly.nLoadFile(String path, Evidence evidence) at System.Reflection.Assembly.LoadFile(String path) at Cjack.Druid.SourcePluginManager.LoadPlugin(String filePath) in C:\Documents and Settings\Annie Tormey\My Documents\Visual Studio 2008\Projects\DruidAddin2003\Druid\SourcePluginManager.cs:line 26 } This is extremely frustrating because it runs perfectly fine for Office 2010 and as a standalone application. Thank-you to anyone who can give me an answer as to why this is happening or a solution to fix it. Thank-you for your time.

• Eclipse Plug-In Installation Issues

  - by Mudu

  Hi all I'm beginning to work with Eclipse for some Java development. I'm quite new to Eclipse, as I am a Visual Studio developer normally. I tried to install the CheckStyle Eclipse Plug-In and Subversive, using the Eclipse "Install new Software" feature. No errors, everything seems to have worked well. Clicking on "What software is already installed?" in the Install-dialogue shows me a list of installed plug-ins. Both Subversive and CheckStyle for Eclipse are listed. My only problem is that neither of them "work", that means I cannot see any new UI elements. According to the manual I have, I should see a new node "CheckStyle" in a project's properties. I haven't. I don't know exactly what Subversive looks like, but I'm sure there's a way to conveniently perform check-out operations etc. Manually copying the downloaded plug-in to the dropins-folder and restarting Eclipse subsequently does not help either. Is there a way to reliably find out whether there occurred any errors - I have no error message at all, what drives me crazy and makes the problem pretty difficult to describe/Google... Any help would be very cool! Cheers Matthias

• Handling Types Defined in Plug-ins That Are No Longer Available

  - by Chris

  I am developing a .NET framework application that allows users to maintain and save "projects". A project can consist of components whose types are defined in the assemblies of the framework itself and/or in third-party assemblies that will be made available to the framework via a yet-to-be-built plug-in architecture. When a project is saved, it is simply binary-serialised to file. Projects are portable, so multiple users can load the same project into their own instances of the framework (just as different users may open the same MSWord document in their own local copies of MSWord). What's more, the plug-ins available to one user's framework might not be available to that of another. I need some way of ensuring that when a user attempts to open (i.e. deserialise) a project that includes a type whose defining assembly cannot be found (either because of a framework version incompatibility or the absence of a plug-in), the project still opens but the offending type is somehow substituted or omitted. Trouble is, the research I've done to date does not even hint at a suitable approach. Any ideas would be much appreciated, thanks.

• Broadcast live video from web-cam via plug-in

  - by Freebrainz

  Hello guys! Could you please suggest me what kind of software should I use to broadcast live video from webcam? Web-cam is connected via USB to my server. I want to broadcast video from my webcam on my web-page (HTML, ASP.NET - doesn't matter). I don't want to develop video broadcasting from the beginning - it takes a lot of time to implement good system. I'm looking for ready-to-use plug-in/widget for my site. I found ustream.tv, but live video start playing with delay about 2 seconds... You know, it's not real-time. I need something like Skype/icq/ooVoo... plug-in/widget for my web-site. Are these plug-ins exists in internet? P.S. I know that VideoLAN has ActiveX control. Does VLC provide me with real-time video broadcasting from webcam without any delays like Skype? Thank you!

• Microsoft and jQuery

  - by Rick Strahl

  The jQuery JavaScript library has been steadily getting more popular and with recent developments from Microsoft, jQuery is also getting ever more exposure on the ASP.NET platform including now directly from Microsoft. jQuery is a light weight, open source DOM manipulation library for JavaScript that has changed how many developers think about JavaScript. You can download it and find more information on jQuery on www.jquery.com. For me jQuery has had a huge impact on how I develop Web applications and was probably the main reason I went from dreading to do JavaScript development to actually looking forward to implementing client side JavaScript functionality. It has also had a profound impact on my JavaScript skill level for me by seeing how the library accomplishes things (and often reviewing the terse but excellent source code). jQuery made an uncomfortable development platform (JavaScript + DOM) a joy to work on. Although jQuery is by no means the only JavaScript library out there, its ease of use, small size, huge community of plug-ins and pure usefulness has made it easily the most popular JavaScript library available today. As a long time jQuery user, I’ve been excited to see the developments from Microsoft that are bringing jQuery to more ASP.NET developers and providing more integration with jQuery for ASP.NET’s core features rather than relying on the ASP.NET AJAX library. Microsoft and jQuery – making Friends jQuery is an open source project but in the last couple of years Microsoft has really thrown its weight behind supporting this open source library as a supported component on the Microsoft platform. When I say supported I literally mean supported: Microsoft now offers actual tech support for jQuery as part of their Product Support Services (PSS) as jQuery integration has become part of several of the ASP.NET toolkits and ships in several of the default Web project templates in Visual Studio 2010. The ASP.NET MVC 3 framework (still in Beta) also uses jQuery for a variety of client side support features including client side validation and we can look forward toward more integration of client side functionality via jQuery in both MVC and WebForms in the future. In other words jQuery is becoming an optional but included component of the ASP.NET platform. PSS support means that support staff will answer jQuery related support questions as part of any support incidents related to ASP.NET which provides some piece of mind to some corporate development shops that require end to end support from Microsoft. In addition to including jQuery and supporting it, Microsoft has also been getting involved in providing development resources for extending jQuery’s functionality via plug-ins. Microsoft’s last version of the Microsoft Ajax Library – which is the successor to the native ASP.NET AJAX Library – included some really cool functionality for client templates, databinding and localization. As it turns out Microsoft has rebuilt most of that functionality using jQuery as the base API and provided jQuery plug-ins of these components. Very recently these three plug-ins were submitted and have been approved for inclusion in the official jQuery plug-in repository and been taken over by the jQuery team for further improvements and maintenance. Even more surprising: The jQuery-templates component has actually been approved for inclusion in the next major update of the jQuery core in jQuery V1.5, which means it will become a native feature that doesn’t require additional script files to be loaded. Imagine this – an open source contribution from Microsoft that has been accepted into a major open source project for a core feature improvement. Microsoft has come a long way indeed! What the Microsoft Involvement with jQuery means to you For Microsoft jQuery support is a strategic decision that affects their direction in client side development, but nothing stopped you from using jQuery in your applications prior to Microsoft’s official backing and in fact a large chunk of developers did so readily prior to Microsoft’s announcement. Official support from Microsoft brings a few benefits to developers however. jQuery support in Visual Studio 2010 means built-in support for jQuery IntelliSense, automatically added jQuery scripts in many projects types and a common base for client side functionality that actually uses what most developers are already using. If you have already been using jQuery and were worried about straying from the Microsoft line and their internal Microsoft Ajax Library – worry no more. With official support and the change in direction towards jQuery Microsoft is now following along what most in the ASP.NET community had already been doing by using jQuery, which is likely the reason for Microsoft’s shift in direction in the first place. ASP.NET AJAX and the Microsoft AJAX Library weren’t bad technology – there was tons of useful functionality buried in these libraries. However, these libraries never got off the ground, mainly because early incarnations were squarely aimed at control/component developers rather than application developers. For all the functionality that these controls provided for control developers they lacked in useful and easily usable application developer functionality that was easily accessible in day to day client side development. The result was that even though Microsoft shipped support for these tools in the box (in .NET 3.5 and 4.0), other than for the internal support in ASP.NET for things like the UpdatePanel and the ASP.NET AJAX Control Toolkit as well as some third party vendors, the Microsoft client libraries were largely ignored by the developer community opening the door for other client side solutions. Microsoft seems to be acknowledging developer choice in this case: Many more developers were going down the jQuery path rather than using the Microsoft built libraries and there seems to be little sense in continuing development of a technology that largely goes unused by the majority of developers. Kudos for Microsoft for recognizing this and gracefully changing directions. Note that even though there will be no further development in the Microsoft client libraries they will continue to be supported so if you’re using them in your applications there’s no reason to start running for the exit in a panic and start re-writing everything with jQuery. Although that might be a reasonable choice in some cases, jQuery and the Microsoft libraries work well side by side so that you can leave existing solutions untouched even as you enhance them with jQuery. The Microsoft jQuery Plug-ins – Solid Core Features One of the most interesting developments in Microsoft’s embracing of jQuery is that Microsoft has started contributing to jQuery via standard mechanism set for jQuery developers: By submitting plug-ins. Microsoft took some of the nicest new features of the unpublished Microsoft Ajax Client Library and re-wrote these components for jQuery and then submitted them as plug-ins to the jQuery plug-in repository. Accepted plug-ins get taken over by the jQuery team and that’s exactly what happened with the three plug-ins submitted by Microsoft with the templating plug-in even getting slated to be published as part of the jQuery core in the next major release (1.5). The following plug-ins are provided by Microsoft: jQuery Templates – a client side template rendering engine jQuery Data Link – a client side databinder that can synchronize changes without code jQuery Globalization – provides formatting and conversion features for dates and numbers The first two are ports of functionality that was slated for the Microsoft Ajax Library while functionality for the globalization library provides functionality that was already found in the original ASP.NET AJAX library. To me all three plug-ins address a pressing need in client side applications and provide functionality I’ve previously used in other incarnations, but with more complete implementations. Let’s take a close look at these plug-ins. jQuery Templates http://api.jquery.com/category/plugins/templates/ Client side templating is a key component for building rich JavaScript applications in the browser. Templating on the client lets you avoid from manually creating markup by creating DOM nodes and injecting them individually into the document via code. Rather you can create markup templates – similar to the way you create classic ASP server markup – and merge data into these templates to render HTML which you can then inject into the document or replace existing content with. Output from templates are rendered as a jQuery matched set and can then be easily inserted into the document as needed. Templating is key to minimize client side code and reduce repeated code for rendering logic. Instead a single template can be used in many places for updating and adding content to existing pages. Further if you build pure AJAX interfaces that rely entirely on client rendering of the initial page content, templates allow you to a use a single markup template to handle all rendering of each specific HTML section/element. I’ve used a number of different client rendering template engines with jQuery in the past including jTemplates (a PHP style templating engine) and a modified version of John Resig’s MicroTemplating engine which I built into my own set of libraries because it’s such a commonly used feature in my client side applications. jQuery templates adds a much richer templating model that allows for sub-templates and access to the data items. Like John Resig’s original Micro Template engine, the core basics of the templating engine create JavaScript code which means that templates can include JavaScript code. To give you a basic idea of how templates work imagine I have an application that downloads a set of stock quotes based on a symbol list then displays them in the document. To do this you can create an ‘item’ template that describes how each of the quotes is renderd as a template inside of the document: <script id="stockTemplate" type="text/x-jquery-tmpl"> <div id="divStockQuote" class="errordisplay" style="width: 500px;"> <div class="label">Company:</div><div><b>${Company}(${Symbol})</b></div> <div class="label">Last Price:</div><div>${LastPrice}</div> <div class="label">Net Change:</div><div> {{if NetChange > 0}} <b style="color:green" >${NetChange}</b> {{else}} <b style="color:red" >${NetChange}</b> {{/if}} </div> <div class="label">Last Update:</div><div>${LastQuoteTimeString}</div> </div> </script> The ‘template’ is little more than HTML with some markup expressions inside of it that define the template language. Notice the embedded ${} expressions which reference data from the quote objects returned from an AJAX call on the server. You can embed any JavaScript or value expression in these template expressions. There are also a number of structural commands like {{if}} and {{each}} that provide for rudimentary logic inside of your templates as well as commands ({{tmpl}} and {{wrap}}) for nesting templates. You can find more about the full set of markup expressions available in the documentation. To load up this data you can use code like the following: <script type="text/javascript"> //var Proxy = new ServiceProxy("../PageMethods/PageMethodsService.asmx/"); $(document).ready(function () { $("#btnGetQuotes").click(GetQuotes); }); function GetQuotes() { var symbols = $("#txtSymbols").val().split(","); $.ajax({ url: "../PageMethods/PageMethodsService.asmx/GetStockQuotes", data: JSON.stringify({ symbols: symbols }), // parameter map type: "POST", // data has to be POSTed contentType: "application/json", timeout: 10000, dataType: "json", success: function (result) { var quotes = result.d; var jEl = $("#stockTemplate").tmpl(quotes); $("#quoteDisplay").empty().append(jEl); }, error: function (xhr, status) { alert(status + "\r\n" + xhr.responseText); } }); }; </script> In this case an ASMX AJAX service is called to retrieve the stock quotes. The service returns an array of quote objects. The result is returned as an object with the .d property (in Microsoft service style) that returns the actual array of quotes. The template is applied with: var jEl = $("#stockTemplate").tmpl(quotes); which selects the template script tag and uses the .tmpl() function to apply the data to it. The result is a jQuery matched set of elements that can then be appended to the quote display element in the page. The template is merged against an array in this example. When the result is an array the template is automatically applied to each each array item. If you pass a single data item – like say a stock quote – the template works exactly the same way but is applied only once. Templates also have access to a $data item which provides the current data item and information about the tempalte that is currently executing. This makes it possible to keep context within the context of the template itself and also to pass context from a parent template to a child template which is very powerful. Templates can be evaluated by using the template selector and calling the .tmpl() function on the jQuery matched set as shown above or you can use the static $.tmpl() function to provide a template as a string. This allows you to dynamically create templates in code or – more likely – to load templates from the server via AJAX calls. In short there are options The above shows off some of the basics, but there’s much for functionality available in the template engine. Check the documentation link for more information and links to additional examples. The plug-in download also comes with a number of examples that demonstrate functionality. jQuery templates will become a native component in jQuery Core 1.5, so it’s definitely worthwhile checking out the engine today and get familiar with this interface. As much as I’m stoked about templating becoming part of the jQuery core because it’s such an integral part of many applications, there are also a couple shortcomings in the current incarnation: Lack of Error Handling Currently if you embed an expression that is invalid it’s simply not rendered. There’s no error rendered into the template nor do the various  template functions throw errors which leaves finding of bugs as a runtime exercise. I would like some mechanism – optional if possible – to be able to get error info of what is failing in a template when it’s rendered. No String Output Templates are always rendered into a jQuery matched set and there’s no way that I can see to directly render to a string. String output can be useful for debugging as well as opening up templating for creating non-HTML string output. Limited JavaScript Access Unlike John Resig’s original MicroTemplating Engine which was entirely based on JavaScript code generation these templates are limited to a few structured commands that can ‘execute’. There’s no code execution inside of script code which means you’re limited to calling expressions available in global objects or the data item passed in. This may or may not be a big deal depending on the complexity of your template logic. Error handling has been discussed quite a bit and it’s likely there will be some solution to that particualar issue by the time jQuery templates ship. The others are relatively minor issues but something to think about anyway. jQuery Data Link http://api.jquery.com/category/plugins/data-link/ jQuery Data Link provides the ability to do two-way data binding between input controls and an underlying object’s properties. The typical scenario is linking a textbox to a property of an object and have the object updated when the text in the textbox is changed and have the textbox change when the value in the object or the entire object changes. The plug-in also supports converter functions that can be applied to provide the conversion logic from string to some other value typically necessary for mapping things like textbox string input to say a number property and potentially applying additional formatting and calculations. In theory this sounds great, however in reality this plug-in has some serious usability issues. Using the plug-in you can do things like the following to bind data: person = { firstName: "rick", lastName: "strahl"}; $(document).ready( function() { // provide for two-way linking of inputs $("form").link(person); // bind to non-input elements explicitly $("#objFirst").link(person, { firstName: { name: "objFirst", convertBack: function (value, source, target) { $(target).text(value); } } }); $("#objLast").link(person, { lastName: { name: "objLast", convertBack: function (value, source, target) { $(target).text(value); } } }); }); This code hooks up two-way linking between a couple of textboxes on the page and the person object. The first line in the .ready() handler provides mapping of object to form field with the same field names as properties on the object. Note that .link() does NOT bind items into the textboxes when you call .link() – changes are mapped only when values change and you move out of the field. Strike one. The two following commands allow manual binding of values to specific DOM elements which is effectively a one-way bind. You specify the object and a then an explicit mapping where name is an ID in the document. The converter is required to explicitly assign the value to the element. Strike two. You can also detect changes to the underlying object and cause updates to the input elements bound. Unfortunately the syntax to do this is not very natural as you have to rely on the jQuery data object. To update an object’s properties and get change notification looks like this: function updateFirstName() { $(person).data("firstName", person.firstName + " (code updated)"); } This works fine in causing any linked fields to be updated. In the bindings above both the firstName input field and objFirst DOM element gets updated. But the syntax requires you to use a jQuery .data() call for each property change to ensure that the changes are tracked properly. Really? Sure you’re binding through multiple layers of abstraction now but how is that better than just manually assigning values? The code savings (if any) are going to be minimal. As much as I would like to have a WPF/Silverlight/Observable-like binding mechanism in client script, this plug-in doesn’t help much towards that goal in its current incarnation. While you can bind values, the ‘binder’ is too limited to be really useful. If initial values can’t be assigned from the mappings you’re going to end up duplicating work loading the data using some other mechanism. There’s no easy way to re-bind data with a different object altogether since updates trigger only through the .data members. Finally, any non-input elements have to be bound via code that’s fairly verbose and frankly may be more voluminous than what you might write by hand for manual binding and unbinding. Two way binding can be very useful but it has to be easy and most importantly natural. If it’s more work to hook up a binding than writing a couple of lines to do binding/unbinding this sort of thing helps very little in most scenarios. In talking to some of the developers the feature set for Data Link is not complete and they are still soliciting input for features and functionality. If you have ideas on how you want this feature to be more useful get involved and post your recommendations. As it stands, it looks to me like this component needs a lot of love to become useful. For this component to really provide value, bindings need to be able to be refreshed easily and work at the object level, not just the property level. It seems to me we would be much better served by a model binder object that can perform these binding/unbinding tasks in bulk rather than a tool where each link has to be mapped first. I also find the choice of creating a jQuery plug-in questionable – it seems a standalone object – albeit one that relies on the jQuery library – would provide a more intuitive interface than the current forcing of options onto a plug-in style interface. Out of the three Microsoft created components this is by far the least useful and least polished implementation at this point. jQuery Globalization http://github.com/jquery/jquery-global Globalization in JavaScript applications often gets short shrift and part of the reason for this is that natively in JavaScript there’s little support for formatting and parsing of numbers and dates. There are a number of JavaScript libraries out there that provide some support for globalization, but most are limited to a particular portion of globalization. As .NET developers we’re fairly spoiled by the richness of APIs provided in the framework and when dealing with client development one really notices the lack of these features. While you may not necessarily need to localize your application the globalization plug-in also helps with some basic tasks for non-localized applications: Dealing with formatting and parsing of dates and time values. Dates in particular are problematic in JavaScript as there are no formatters whatsoever except the .toString() method which outputs a verbose and next to useless long string. With the globalization plug-in you get a good chunk of the formatting and parsing functionality that the .NET framework provides on the server. You can write code like the following for example to format numbers and dates: var date = new Date(); var output = $.format(date, "MMM. dd, yy") + "\r\n" + $.format(date, "d") + "\r\n" + // 10/25/2010 $.format(1222.32213, "N2") + "\r\n" + $.format(1222.33, "c") + "\r\n"; alert(output); This becomes even more useful if you combine it with templates which can also include any JavaScript expressions. Assuming the globalization plug-in is loaded you can create template expressions that use the $.format function. Here’s the template I used earlier for the stock quote again with a couple of formats applied: <script id="stockTemplate" type="text/x-jquery-tmpl"> <div id="divStockQuote" class="errordisplay" style="width: 500px;"> <div class="label">Company:</div><div><b>${Company}(${Symbol})</b></div> <div class="label">Last Price:</div> <div>${$.format(LastPrice,"N2")}</div> <div class="label">Net Change:</div><div> {{if NetChange > 0}} <b style="color:green" >${NetChange}</b> {{else}} <b style="color:red" >${NetChange}</b> {{/if}} </div> <div class="label">Last Update:</div> <div>${$.format(LastQuoteTime,"MMM dd, yyyy")}</div> </div> </script> There are also parsing methods that can parse dates and numbers from strings into numbers easily: alert($.parseDate("25.10.2010")); alert($.parseInt("12.222")); // de-DE uses . for thousands separators As you can see culture specific options are taken into account when parsing. The globalization plugin provides rich support for a variety of locales: Get a list of all available cultures Query cultures for culture items (like currency symbol, separators etc.) Localized string names for all calendar related items (days of week, months) Generated off of .NET’s supported locales In short you get much of the same functionality that you already might be using in .NET on the server side. The plugin includes a huge number of locales and an Globalization.all.min.js file that contains the text defaults for each of these locales as well as small locale specific script files that define each of the locale specific settings. It’s highly recommended that you NOT use the huge globalization file that includes all locales, but rather add script references to only those languages you explicitly care about. Overall this plug-in is a welcome helper. Even if you use it with a single locale (like en-US) and do no other localization, you’ll gain solid support for number and date formatting which is a vital feature of many applications. Changes for Microsoft It’s good to see Microsoft coming out of its shell and away from the ‘not-built-here’ mentality that has been so pervasive in the past. It’s especially good to see it applied to jQuery – a technology that has stood in drastic contrast to Microsoft’s own internal efforts in terms of design, usage model and… popularity. It’s great to see that Microsoft is paying attention to what customers prefer to use and supporting the customer sentiment – even if it meant drastically changing course of policy and moving into a more open and sharing environment in the process. The additional jQuery support that has been introduced in the last two years certainly has made lives easier for many developers on the ASP.NET platform. It’s also nice to see Microsoft submitting proposals through the standard jQuery process of plug-ins and getting accepted for various very useful projects. Certainly the jQuery Templates plug-in is going to be very useful to many especially since it will be baked into the jQuery core in jQuery 1.5. I hope we see more of this type of involvement from Microsoft in the future. Kudos!© Rick Strahl, West Wind Technologies, 2005-2010Posted in jQuery  ASP.NET

• Deploying play! 2.0 application on an apache server with a reverse proxy

  - by locrizak

  I'm trying to deploy my play! 2.0 application on an Ubuntu 11.10 server and I have been running into error after error and hope someone can help me here. I am try to deploy my Play! application using a reverse proxy on Apache 2. I have enabled the apache proxy modules and configured the proxy.conf file in mods_enabled. The vhost for my domain looks like this: <Directory /var/www/stage.domain.com AllowOverride None Order Deny,Allow Deny from all </Directory <VirtualHost *:80 DocumentRoot /var/www/stage.domain.com/web ServerName stage.domain.com ServerAdmin [email protected] # ProxyRequests Off # ProxyPreserveHost On <Proxy * Order allow,deny Allow from all </Proxy # ProxyVia On # ProxyPass /play/ http://localhost:9000/ # ProxyPassReverse /play/ http://localhost:9000/ ErrorLog /var/log/ispconfig/httpd/stage.domain.com/error.log ErrorDocument 400 /error/400.html ErrorDocument 401 /error/401.html ErrorDocument 403 /error/403.html ErrorDocument 404 /error/404.html ErrorDocument 405 /error/405.html ErrorDocument 500 /error/500.html ErrorDocument 502 /error/502.html ErrorDocument 503 /error/503.html <IfModule mod_ssl.c </IfModule <Directory /var/www/stage.domain.com/web Options FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory <Directory /var/www/clients/client2/web7/web Options FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory # Clear PHP settings of this website <FilesMatch "\.ph(p3?|tml)$" SetHandler None </FilesMatch # mod_php enabled AddType application/x-httpd-php .php .php3 .php4 .php5 php_admin_value sendmail_path "/usr/sbin/sendmail -t -i [email protected]" php_admin_value upload_tmp_dir /var/www/clients/client2/web7/tmp php_admin_value session.save_path /var/www/clients/client2/web7/tmp # PHPIniDir /var/www/conf/web7 php_admin_value open_basedir /var/www/clients/client2/web7/:/var/www/clients/client2/web7/web:/va$ # add support for apache mpm_itk <IfModule mpm_itk_module AssignUserId web7 client2 </IfModule <IfModule mod_dav_fs.c # Do not execute PHP files in webdav directory <Directory /var/www/clients/client2/web7/webdav <FilesMatch "\.ph(p3?|tml)$" SetHandler None </FilesMatch </Directory # DO NOT REMOVE THE COMMENTS! # IF YOU REMOVE THEM, WEBDAV WILL NOT WORK ANYMORE! # WEBDAV BEGIN # WEBDAV END </IfModule # <Location /play/ # ProxyPass http://localhost:9000/ # SetEnv force-proxy-request-1.0 1 # SetEnv proxy-nokeepalive 1 # </Location ProxyRequests Off ProxyPass /play/ http://localhost:9000/ ProxyPassReverse /play/ localhost:9000/ ProxyPass /play http://localhost:9000/ ProxyPassReverse /play http://localhost:9000/ # SetEnv force-proxy-request-1.0 1 # SetEnv proxy-nokeepalive 1 </VirtualHost This vhost file was generated by ispconfig and I have not touched anything that was there before just added onto. As you can see by the commented out parts I have tried a lot of different things based on random tutorials I have found but all of them have ended up in Internal Server Error, 503 and most often a '502 Bad Gateway`. I can start play and it does connect successfully to my database. I can get a page to show up when there is an error and the play! stack trace error pages comes up but where everything is fine I get one of the errors above. My application.conf file looks like this: db info ....... application.mode=PROD logger.root=ERROR # Logger used by the framework: logger.play=INFO # Logger provided to your application: logger.application=DEBUG http.path="/play/" XForwardedSupport="127.0.0.1" And my hosts file looks like this (I have never changed or added anything to the host file): 127.0.0.1 localhost 127.0.1.1 matrix # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters Any insights onto what I might be doing wrong or if theres anything I can try please let me know! Thanks!! Edit Again the reverse proxy will work (I checked with sending to to google.com). Its when there is a successful connection to Netty. It's like Netty refuses the connection to the page. Edit 2 output from apachectl -S _default_:8081 127.0.0.1 (/etc/apache2/sites-enabled/000-apps.vhost:10) *:8090 is a NameVirtualHost default server 127.0.0.1 (/etc/apache2/sites-enabled/000-ispconfig.vhost:10) port 8090 namevhost 127.0.0.1 (/etc/apache2/sites-enabled/000-ispconfig.vhost:10) *:80 is a NameVirtualHost default server 127.0.0.1 (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost 127.0.0.1 (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost stage.domain.com (/etc/apache2/sites-enabled/100-stage.domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7)
