• What java web framework best accomodates web ui designers?

  - by Brian Laframboise

  What Java web framework out there best supports a role of "web UI designer", that is, lets you: Use popular web design tools (xhtml validators, css editors, what have you) on your views/pages View changes without running on a server Rapidly prototype different UI options Supports a (somewhatly) clean separation between "developer" and "designer" (terminology intentionally vague) We, like many others, have found these capabilities sorely lacking in our large, legacy Struts 1.x apps that use lots of JSP fragments and includes. We've decided to port our apps to a JSR-168/268 portal environment, but we have not decided on what Java web framework will power the portlets. We're open to any kind (action-based, component-based, etc) and a key criterion is how well it supports the role described above. I'm intrigued by Tapestry which claims that its views are XHTML compliant pages (that simply have extra Tapestry-specific attributes added onto them to be processed at runtime). This sounds like it would play well with a web ui designer's toolkit. However, I'd like to know if this is what actually happens in the real world, or if compromises are necessary. Of course, if there's something much better than Tapestry, I'd love to hear about it!

• MonoRail: Testing, Route Extensions, Folder Structures

  - by Kezzer

  I've got a few questions related to the use of MonoRail Testing Does everyone tend to use NUnit for their testing? I haven't worked enough with testing to know if this is a good testing framework to use. I'm just looking to get more into testing my applications a lot more than before and wanted to know if there's any general guidelines. Are you supposed to copy the controller over to a test area and just rename it with test in the name and re-run it? How do you ensure your test project and main project coincide with one another? Is it just a case of copying everything over again or are there tools available to do it for you? Route Extensions MonoRail tends to use <action>.rails, can you omit the .rails part if you configure your routing correctly? Why does this seem to be the standard? Folder Structures I haven't found anywhere which really points out your standard folder structure. Sure, you have Controllers, Models, and Views. But your Models folder should contain your data access objects as well. I've seen some have something like -> Models -> DaoClasses -> Entities But what about custom structures used to get data out of views? And if you're using NHibernate, where's a good place to stick the mappings? I know it's entirely dependent on the developer, but I haven't really seen any standard approach. Cheers

• What is more viable to use? Javascript libraries or UI Programming tools?

  - by Haresh Karkar

  What is more viable to use:- Javascript Libraries: YUI, jQuery, ExtJs OR UI Programming tools: GWT, ExtGWT, SmartGWT It has become very difficult to choose between them as they are constantly increasing their capabilities to meet newer requirements. We all know the power of jQuery in UI manipulations. The latest news from Microsoft about jQuery being officially part of .Net developr’s toolkit will definitely make jQuery a preferred choice against other JavaScript libraries [See link: http://weblogs.asp.net/scottgu/archive/2008/09/28/jquery-and-microsoft.aspx]. But on the other hand, GWT is building a framework which could be used on client as well as on the sever side. This is definitely going to make developers’ life easy as it does not require developer to be an expert in browser quirks, XMLHttpRequest, and JavaScript in order to develop high-performance web applications. It includes SDK (Java API libraries, compiler, and development server which allows to write client-side applications in Java and deploy them as JavaScript), Speed Tracer and plug-in for Eclipse. GWT is used by many products like Google Wave and AdWords. So question is still un-answered, what is more viable to use? Any thoughts?

• Deriving an HTMLElement Object from jQuery Object

  - by Jasconius

  I'm doing a fairly exhaustive series of DOM manipulations where a few elements (specifically form elements) have some events. I am dynamically creating (actually cloning from a source element) several boxes and assigning a change() event to them. The change event executes, and within the context of the event, "this" is the HTML Element Object. What I need to do at this point however is determine a contact for this HTML Element Object. I have these objects stored already as jQuery entities in assorted arrays, but obviously [HTMLElement Object] != [Object Object] And the trick is that I cannot cast $(this) and make a valid comparison since that would create a new object and the pointer would be different. So... I've been banging my head against this for a while. In the past I've been able to circumvent this problem by doing an innerHTML comparison, but in this case the objects I am comparing are 100% identical, just there's lots of them. Therefore I need a solid comparison. This would be easy if I could somehow derive the HTMLElement object from my originating jQuery object. Thoughts, other ideas? Help. :(

• Importing Variables from PHP 4 into Flash

  - by Glenn

  I'm trying to get variable importing from a PHP script before I implement it into a larger project. So far all I've gotten is headaches. //this is all thats in test.php other than the open and close brackets. Normally I'd have it doing a mysql_query and putting useful information into the print statement. print( "lamegame.net/test/test.php?val=foo&id=0000&name=Glenn"); All test.as has to do is access the three variables. The problem comes in that 'val' is undefined. The id and name variables however are just fine and return 0000 and Glenn respectively. package { import flash.display.MovieClip; import flash.text.TextField; import flash.events.; import flash.net.; public class test extends MovieClip { public function test() { super(); //prep request var request:URLRequest = new URLRequest("test.php"); request.method = URLRequestMethod.GET; var loader:URLLoader = new URLLoader(); //load request loader.dataFormat = URLLoaderDataFormat.VARIABLES; loader.addEventListener(Event.COMPLETE, dataLoaded); loader.load(request); } public function dataLoaded(e:Event):void { var name = e.target.data.name; var id = e.target.data.id; var val = e.target.data.val; trace("Val: " + val + "ID: " + id + " Name: " + name); } } }

• How to save a picture to a file?

  - by Peter vdL

  I'm trying to use a standard Intent that will take a picture, then allow approval or retake. Then I want to save the picture into a file. Here's the Intent I am using: Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE ); startActivityForResult( intent, 22 ); The docs at http://developer.android.com/reference/android/provider/MediaStore.html#ACTION_IMAGE_CAPTURE say "The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT." I don't pass extra output, I hope to get a Bitmap object in the extra field of the Intent passed into onActivityResult() (for this request). So where/how do you extract it? Intent has a getExtras(), but that returns a Bundle, and Bundle wants a key string to give you something back. What do you invoke on the Intent to extract the bitmap?

• Flash video slooow in AIR 2 HTMLLoader component

  - by shane

  I am working on a full screen kiosk application in Flex 4/Air 2 using Flash Builder 4. We have a company training website which staff can access via the kiosk, and the main content is interactive flash training videos. Our target machines are by no means 'beefy', they are Atom n270s @ 1.6Ghz with 1Gb RAM. As it stands the videos are all but unusable when used from within the Air application, the application becomes completely unresponsive (100% cpu usage, click events take approx 5-10 seconds to register). So far I have tried: increasing the default frame rate from 24fps to 60. No improvement. nativeWindow.stage.frameRate = 60; running the videos in a stripped down version of my app, just a full screen HTMLLoader component pointed at the training website. No better than before. disabled hyper threading. The Atom CPU is split into two virtual cores, and the AIR app was only able to use one thread so maxed out at 50% CPU usage. Since the kiosk will only run the AIR app I am happy to loose hyper threading to increase the performance of the Air app. Marginal Improvement. The same website with the same videos is responsive if viewed in ie7 on the same machine, although Internet Explorer takes advantage of the CPU’s hyper threading. The flash videos are built with Adobe Captivate and from what I understand employee JavaScript to relay results back to the server. I will add more information about the video content asap as the training guru is back in the office later this week.

• Mercurial: a few questions all related to .hgignore

  - by WizardOfOdds

  I've been working for a long time with a .hgignore file that was fine and recently added one new type of files to ignore. When running "hg status", I noticed this: M .hgignore So Mercurial considers the .hgignore to be a file that needs to be tracked (if it's a the root of the project). Now I've read various docs but my points weren't specifically adressed so here are some very detailed questions which hopefully can help me figure this out (it would be great is someone answering could quote and address these three points [even with a simply yes/no answer for each question]): Should .hgignore be at the root of the project? (I guess it should, seen that a developer can potentially be working on several projects which would all have different .hgignore requirements) Can .hgignore be ignored be Mercurial? If it can be ignored, should .hgignore be ignored by Mercurial (which is different than the previous question) In the case where .hgignore should not be ignored, can't some really bad thing happens if you suddenly rollback way earlier, when a really old and incomplete .hgignore was used? I think I saw weird things happening with certain per-user IDE project files (I'm not saying all IDEs project files are per-user only, but some definitely are) that were supposed to be ignored, but then the user rolls back to an old version, where an old .hgignore gets used, and then suddenly files supposed to be ignored are committed because the old .hgignore didn't exclude these.

• need some help in Abraham twitteroauth class

  - by diEcho

  Hello All, i m learning how to use twitter from twitter developer link on Authenticating Requests with OAuth page i was debugging my code with given procedure on Sending the user to authorization section there is written that if you are using the callback flow, your oauth_callback should have received back your oauth_token (the same that you sent, your "request token") and a field called the oauth_verifier. You'll need that for the next step. Here's the response I received: oauth_token=8ldIZyxQeVrFZXFOZH5tAwj6vzJYuLQpl0WUEYtWc&oauth_verifier=pDNg57prOHapMbhv25RNf75lVRd6JDsni1AJJIDYoTY my original code is require_once('twitteroauth/twitteroauth.php'); require_once('config.php'); /* Build TwitterOAuth object with client credentials. */ $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET); /* Get temporary credentials. */ $request_token = $connection->getRequestToken(OAUTH_CALLBACK); /* Save temporary credentials to session. */ $_SESSION['oauth_token'] = $token = $request_token['oauth_token']; $_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret']; /* If last connection failed don't display authorization link. */ switch ($connection->http_code) { case 200: /* Build authorize URL and redirect user to Twitter. */ echo "<br/>Authorize URL:".$url = $connection->getAuthorizeURL($token); //header('Location: ' . $url); break; default: /* Show notification if something went wrong. */ echo 'Could not connect to Twitter.

• Is there a way in .NET to access the bytecode/IL/CLR that is currently running?

  - by Alix

  Hi. I'd like to have access to the bytecode that is currently running or about to run in order to detect certain instructions and take specific actions (depending the instructions). In short, I'd like to monitor the bytecode in order to add safety control. Is this possible? I know there are some AOP frameworks that notify you of specific events, like an access to a field or the invocation of a method, but I'd like to skip that extra layer and just look at all the bytecode myself, throughout the entire execution of the application. I've already looked at the following questions (...among many many others ;) ):     Preprocessing C# - Detecting Methods     What CLR/.NET bytecode tools exist? as well as several AOP frameworks (although not in great detail, since they don't seem to do quite what I need) and I'm familiar with Mono.Cecil. I appreciate alternative suggestions, but I don't want to introduce the overhead of an AOP framework when what I actually need is access to the bytecode, without all the stuff they add on top to make it more user-friendly (... admittedly very useful stuff when you don't want to go low-level). Thanks :)

• Pros & Cons of Google App Engine

  - by Rishi

  Pros & Cons of Google App Engine [An Updated List 21st Aug 09] Help me Compile a List of all the Advantages & Disadvantages of Building an Application on the Google App Engine Pros: 1) No Need to buy Servers or Server Space (no maintenance). 2) Makes solving the problem of scaling much easier. Cons: 1) Locked into Google App Engine ?? 2)Developers have read-only access to the filesystem on App Engine. 3)App Engine can only execute code called from an HTTP request (except for scheduled background tasks). 4)Users may upload arbitrary Python modules, but only if they are pure-Python; C and Pyrex modules are not supported. 5)App Engine limits the maximum rows returned from an entity get to 1000 rows per Datastore call. 6)Java applications may only use a subset (The JRE Class White List) of the classes from the JRE standard edition. 7)Java applications cannot create new threads. Known Issues!! http://code.google.com/p/googleappengine/issues/list Hard limits Apps per developer - 10 Time per request - 30 sec Files per app - 3,000 HTTP response size - 10 MB Datastore item size - 1 MB Application code size - 150 MB Pro or Con? App Engine's infrastructure removes many of the system administration and development challenges of building applications to scale to millions of hits. Google handles deploying code to a cluster, monitoring, failover, and launching application instances as necessary. While other services let users install and configure nearly any *NIX compatible software, App Engine requires developers to use Python or Java as the programming language and a limited set of APIs. Current APIs allow storing and retrieving data from a BigTable non-relational database; making HTTP requests; sending e-mail; manipulating images; and caching. Most existing Web applications can't run on App Engine without modification, because they require a relational database.

• Help! I've learned jQuery... now I want to learn JavaScript

  - by Derek Adair

  I am a self-taught web developer/programmer. I started out about two years ago by learning how to make simple dynamic websites with HTML/CSS/PHP. Then I started dabbling with animation... Enter jQuery I've become quite proficient with jQuery over the last year and I've even started making my own plugins. I've spent most of my effort learning how to beautify websites with fancy effects and what not. Upon tackling my first full-blown application, I realized how under-developed my knowledge of JavaScript actually is. jQuery has allowed me to rely on its framework so heavily that I rarely use any interesting functions, techniques, or whatever that are 'native' to the JavaScript language. For example: I have a basic understanding of what a closure is... but I am unsure where this technique can actually benefit me. Although as I understand it, that's what my jQuery plugins do with (function ($){//plugin code here})(jQuery). I've seen many posts/blogs/whatever about memory leaks and circular references which is concerning. I'm frustrated because I can wrap my head around the basic concepts of what these are just by reading the articles, but I'm finding that the deeper I go the more I don't understand. The vocabulary alone is burdensome. Let alone how to actually use these techniques/functions/language features. I am trying to figure out what I don't know I'm looking to gather any advice, techniques, articles, books, videos, snippets, examples, potential pitfalls... really anything you have regarding application development with JavaScript/jQuery.

• How do I create a .NET Web Service that Posts items to a users Facebook Wall?

  - by Jourdan

  I'm currently toying around with the Clarity .NET Facebook API but am finding certain situations with authentication to be kind of limiting. I keep going through the tutorials but always end up hitting a brick wall with what I want to do. Perhaps I just cannot do it? I want to make a Web Service that takes in the require credentials (APIKey, SecretKey, UsersId (or Session Key?) and whatever else I would need), and then do various tasks: Post to users wall, add events etc. The problem I am having is this: The current documentation, examples and support provide a way to do this within the context of a Web site. Within this context, the required "connect" popup can be initiated and allow the user to authenticate and and connect the application. From that point on the Web can go on with its business to do what it needs to do. If I close the browser and come back to the page, I have to push the connect button again. Except this time, since I was already logged into facebook, I don't have to go through the whole connection process. But still ... How do applications like Tweetdeck get around this? They seemingly have you connect once, when you install their application, and you don't have to do it again. I would assume that this same idea would have to applied towards making a web service because: You don't know what context the user is in when making the Web service call. The web service methods being called could be coming from a Windows Form app, or code behind in a workflow.

• Using a CALayer in UITableViewCell

  - by Brian

  On each cell of my table view I want to have a bar that the user can slide out from the right. On the bar I plan to have icons. So, to do this I subclassed UITableViewCell. On the cell I have implemented drawRect and in there I have already drawn a gradient and background color on the cell. From there, I can create a CALayer, give it a frame & background color, and add it as a sub layer to the Views subLayers array. I can do all that and it will display my layer on each UITableViewCell. I have added touch events to the cell so I can detect when the user touches the cell and for testing I have made it so when the user swipes, my CALayer gets wider. But the issue is, when the UITableView scrolls and reuses a cell whose CALayer has been widened, it doesn't recreate the CALayer. I have tried [myLayer setNeedsDisplay] and used the drawLayer:inContext method of its delegate and it doesn't get called. I have also tried telling call setNeedsDisplay on the cell in my UITableViewController hoping that that will cause a redraw, but it doesn't work. I'm not sure what I'm missing. I am new to CoreGraphics & CoreAnimation. I have read through the CoreAnimation Developers Guide, but I'm assuming I missing something. Any help would be great.

• What advice would you give a high-schooler interested in tech?

  - by user291991

  (This was originally sent to a group of people I have worked with and trust and it was suggested that I post this here. I've been a software developer, architect, manager, vp, tester, trainer, tech writer, etc., and my presentation is primarily about Android & other mobile application development.) Next week I'm going to be giving a presentation to 3 groups of high schoolers interested in technology and technology careers. One of the things I've been asked to include is any advice that I think would be valuable for them. If you are willing to share, I would like to hear what advice you would give based on your life experiences and observations. What would you be looking for if they approached you about work? Perhaps you are in that age group right now. What do you want to know? Perhaps you are just a few years into the workforce. What do you wish someone had told you but never did? Perhaps you have children, relatives or friends in or soon to be in that age group. What are you worried they don't know about? I'm sure there are other perspectives and questions I'm not even thinking about. I'd like to hear what you have to say about it.

• Shopping list for developing Windows app on Mac

  - by raj.tiwari

  Folks, I need to maintain a C#/.Net desktop application. So, I need to set myself up with Windows(7?) and Visual Studio. My current development machine is a Macbook Pro and I would like to continue using it. Overall, I am considering the following recipe: Install VMWare Fusion or Parallels or VirtualBox for running the Windows OS Buy a version of Windows to develop on Buy Windows Developer tools Having been in the open source universe all this time, I am utterly unfamiliar with the options/packages in the Windows world. I could use some help on the following: Does the recipe above look fine, or do I need to change something? What is a good VM environment to buy/use? VirtualBox is free, but Parallels/VMWare promise Windows app that blend in with my Mac windows. Could use some help on this topic Does MSFT sell a package deal which has bare bones Windows 7 and the necessary dev tools, or do I need to buy the OS and dev tools separately? Since I only need Windows to churn this C# desktop application, What is the OS version and flavor or Visual Studio I should get? Thanks in advance for any pointers. -Raj

• Silverlight 4 race condition with DataGrid master details control

  - by Simon_Weaver

  Basically I want a DataGrid (master) and details (textbox), where DataGrid is disabled during edit of details (forcing people to save/cancel)... Here's what I have... I have a DataGrid which serves as my master data. <data:DataGrid IsEnabled="{Binding CanLoad,ElementName=dsReminders}" ItemsSource="{Binding Data, ElementName=dsReminders}" > Its data comes from a DomainDataSource: <riaControls:DomainDataSource Name="dsReminders" AutoLoad="True" ... I have a bound Textbox which is the 'details' (very simple right now). There are buttons (Save/Cancel) which should be enabled when user tries to edit the text. Unfortunately Silverlight doesn't support UpdateSourceTrigger=PropertyChanged so I have to raise an event: <TextBox Text="{Binding SelectedItem.AcknowledgedNote, Mode=TwoWay, UpdateSourceTrigger=Explicit, ElementName=gridReminders}" TextChanged="txtAcknowledgedNote_TextChanged"/> The event to handle this calls BindingExpression.UpdateSource to update the source immediately: private void txtAcknowledgedNote_TextChanged(object sender, TextChangedEventArgs e) { BindingExpression be = txtAcknowledgedNote.GetBindingExpression(TextBox.TextProperty); be.UpdateSource(); } IN other words - typing in the textbox causes CanLoad of the DomainDataSource to become False (because we're editing). This in turn disables the DataGrid (IsEnabled is bound to it) and enables 'Cancel' and 'Save' buttons. However I'm running up against a race condition if I move quickly through rows in the DataGrid (just clicking random rows). The TextChanged presumably is being called on the textbox and confusing the DomainDataSource which then thinks there's been a change. So how should I disable the DataGrid while editing without having the race condition? One obvious solution would be to use KeyDown events to trigger the call to UpdateSource but I always hate having to do that.

• Looking for Hardware that will easily interface with my .NET code.

  - by SkippyFire

  I'm a .NET C# developer looking to do some hardware interfacing/programming. I just want something super simple to mess around with. I have done one of those basic stamp projects, but I want something with less electrical work. A self-contained piece of hardware would be fine. I'm not really looking to do embedded programming... but that would actually be pretty cool if something was capable of running .net code. I'm looking for something that would be easy to connect, hopefully via USB. Serial ports seems to be more hit or miss nowadays with laptops and netbooks. Something I can easily send data to, like a mini LCD, or series of LED's. Better yet would be something that provides feedback, like a temperature sensor. The best would be something more featured that I could talk to. I would be able to send data to it, and it would send back responses. Maybe something like a servo that could report it's position? Or maybe something that I could set parameters on? Any ideas? Thanks in advance!

• Django Models / SQLAlchemy are bloated! Any truly Pythonic DB models out there?

  - by Luke Stanley

  "Make things as simple as possible, but no simpler." Can we find the solution/s that fix the Python database world? from someAmazingDB import * class Task (model): title = '' isDone = False db.taskList = [] #or db.taskList = expandableTypeCollection(Task) #not sure what this syntax would be db['taskList'].append(Task(title='Beat old sql interfaces',done=False)) db.taskList.append(Task('Illustrate different syntax modes',True)) #at this point it should autosave #we should be able to reload the console and access like: >> from someAmazingDB import * >> print 'Done tasks:' >> for task in db.taskList: >> if task.done: >> print task 'Illustrate different syntax modes' I'm a fan of Python, webPy and Cherry Py, and KISS in general. We're talking automatic Python to SQL type translation or NoSQL. We don't have to totally be SQL compatible! Just a scalable subset or ignore it! Re:model changes, it's ok to ask the developer when they try to change it or have a set of sensible defaults. Here is the challenge: The above code should work with very little modification or thinking required. Why must we put up with compromise when we know better? It's 2010, we should be able to code scalable, simple databases in our sleep. If you think this is important, please upvote!

• Selenium onChange not working

  - by tohop

  Hi, I have tried a number of things to try and get Selenium to pick up an 'onchange' event from a drop down menu, none of which has worked. The offending HTML is: <select onchange="doOpperation(this.options[this.selectedIndex]); this.selectedIndex = 0;" name="opps_ondemand" id="opps_ondemand"> <option value="none" id="ondemand">Mark as...</option> <option cmd="blah1" value="add">Something</option> <option cmd="blah2" value="remove">None</option> </select> I have read that Selenium IDE doesn't record some on* events, and so it would be wise to use fireEvent(): $this->click("opps_ondemand"); $this->select("opps_ondemand", "label=Mark as..."); $this->click("//option[@value='add']"); sleep(3); $this->fireEvent("//select[@id='opps_ondemand']", "change"); However, this does not work (with or without the fireEvent). I have also tried using $this->fireEvent("locator", "click"); instead of $this->click("locator"); but this did nothing. Selenium does not complain about these locators not existing so I am assuming it can see the select/option elements fine. The problem seems to be the onChange event. Does anyone know how to resolve this? Thanks.

• Is there a good tutorial for figuring out what a website is doing so your program can do the same th

  - by brian d foy

  Is there a good guide or tutorial for people who need to programmatically interact with dynamic websites? There's been a rash of Perl questions about that lately, and I haven't found a good resource to point people toward. I'm asking not because I need one but because I don't want to waste my time writing it if it already exists. Although I'm most interested in Perl, the extra tools and techniques are mostly the same. Typically, I see see these problems in people's questions: Handling, setting, and saving cookies Finding and interacting with forms Handling JavaScript inside your user-agent especially things like onLoad, onSumbit, and Ajax Using HTTP sniffer tools Using Web developer plugins in interactive browsers Interacting with DOM, screen scraping, etc. If there's no good tutorial, I'll add it to my list of things to do (unless someone else wants to do it :). Along the way, if you don't have a suggestion for an existing tutorial, please suggest the things that you think should be in a new one, including links, your favorite tools, and your own user-agent development experiences. I don't care about the particular language you use.

• AjaxControlToolkit Resource Files Not Copied To Output in MSBuild Script

  - by Dario Solera

  I'm new to MSBuild, but I managed to setup the following simple script: <Project ToolsVersion="3.5" DefaultTargets="Compile" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <Configuration Condition="'$(Configuration)' == ''">Debug</Configuration> </PropertyGroup> <ItemGroup> <SolutionRoot Include=".." /> <BuildArtifacts Include=".\Artifacts\" /> <SolutionFile Include="..\SolutionName.sln" /> </ItemGroup> <Target Name="Clean"> <RemoveDir Directories="@(BuildArtifacts)" /> </Target> <Target Name="Init" DependsOnTargets="Clean"> <MakeDir Directories="@(BuildArtifacts)" /> </Target> <Target Name="Compile" DependsOnTargets="Init"> <MSBuild Projects="@(SolutionFile)" Properties="OutDir=%(BuildArtifacts.FullPath);Configuration=$(Configuration)" /> <MakeDir Directories="%(BuildArtifacts.FullPath)\_PublishedWebsites\RDE.XAP.UnifiedGui.Web\Temp" /> </Target> </Project> The solution has 23 projects, 4 of which are WebApps. Now, the script works fine and the output is generated correctly. The only problem I counter is with two WebApp projects in the solution that use the AJAX Control Toolkit. The toolkit has a set of folders (e.g. ar, it, es, fr) that contain localized resources. These folders are not copied in the bin directory of the WebApps when the solution is built in MSBuild, but they are copied when it is built in Visual Studio. How can I solve this in a clean manner? I know I could write a (quite convoluted) task that copies the directories after the compile, but it does not seem the right solution to me. Also, neither Google, SO and MSDN could provide more details on this kind of issue.

• Templates vs. coded HTML

  - by Alan Harris-Reid

  I have a web-app consisting of some html forms for maintaining some tables (SQlite, with CherryPy for web-server stuff). First I did it entirely 'the Python way', and generated html strings via. code, with common headers, footers, etc. defined as functions in a separate module. I also like the idea of templates, so I tried Jinja2, which I find quite developer-friendly. In the beginning I thought templates were the way to go, but that was when pages were simple. Once .css and .js files were introduced (not necessarily in the same folder as the .html files), and an ever-increasing number of {{...}} variables and {%...%} commands were introduced, things started getting messy at design-time, even though they looked great at run-time. Things got even more difficult when I needed additional javascript in the or sections. As far as I can see, the main advantages of using templates are: Non-dynamic elements of page can easily be viewed in browser during design. Except for {} placeholders, html is kept separate from python code. If your company has a web-page designer, they can still design without knowing Python. while some disadvantages are: {{}} delimiters visible when viewed at design-time in browser Associated .css and .js files have to be in same folder to see effects in browser at design-time. Data, variables, lists, etc., must be prepared in advanced and either declared globally or passed as parameters to render() function. So - when to use 'hard-coded' HTML, and when to use templates? I am not sure of the best way to go, so I would be interested to hear other developers' views. TIA, Alan
