• Best practice to test a web application, regarding domain name and integration with external service

  - by ycseattle

  I have run into these problems several times and was never able to find a comfortable solution. Let's say my website has the domain name MyDomain.com. When I run the tests on the test machine (a continuous integration server), I will modify the HOSTS file on this machine so the MyDomain.com is mapped to this local machine instead of the real production server. This doesn't work very well for many situations. For example, my application will create subdomain names user1.MyDomain.com dynamically but this is difficult to keep the testing flexible. Another problem is my web application will interact with Amazon S3, and sometimes other service like Amazon Simple Message Queue. I am only comfortable to include these interaction in my tests but I am never happy with my solution for mixing testing and production on Amazon services. Could somebody offer some tips on these issues? I would like to make my testing framework clean and flexible. I am sure this is a common question for all web applications and there must be a mature way to deal with these. Thanks!

• What is the IoC / "Springy" way to handle MVP in GWT? (Hint, probably not the Spring Roo 1.1 way)

  - by Ehrann Mehdan

  This is the Spring Roo 1.1 way of doing a factory that returns a GWT Activity (Yes, Spring Framework) public Activity getActivity(ProxyPlace place) { switch (place.getOperation()) { case DETAILS: return new EmployeeDetailsActivity((EntityProxyId<EmployeeProxy>)place.getProxyId(), requests, placeController, ScaffoldApp.isMobile() ? EmployeeMobileDetailsView.instance() : EmployeeDetailsView.instance()); case EDIT: return makeEditActivity(place); case CREATE: return makeCreateActivity(); } throw new IllegalArgumentException("Unknown operation " + place.getOperation()); } It seems to me that we just went back hundred of years if we use a switch case with constants to make a factory. Now this is official auto generated Spring roo 1.1 with GWT / GAE integration, I kid you not I can only assume this is some executives empty announcements because this is definitly not Spring It seems VMWare and Google were too fast to get something out and didn't quite finish it, isn't it? Am I missing something or this is half baked and by far not the way Spring + GWT MVP should work? Do you have a better example of how Spring, GWT (2.1 MVP approach) and GAE should connect? I would hate to do all the plumbing of managing history and activities like this. (no annotations? IOC?) I also would hate to reinvent the wheel and write my own Spring enhancement just to find someone else did the same, or worse, find out that SpringSource and Google will release roo 1.2 soon and make it right

• Is there some formal way to update the browser detection files for ASP.Net?

  - by Deane

  I have an ASP.Net site on which we're using control adapters. We have the adapters mapped to a "refID" of "Default." These adapters are working fine on all browsers except Chrome and Safari. For those browsers, they do not execute. I've given up trying to figure out why -- I have a question here on SO that no one has been able to answer, and I've been researching it for days now. It's just inexplicable. I have tested the same code in my local environment, and it works just fine. Additionally, no one else can replicate my problem on other servers. It seems to be somehow confined to the machines at my client's site. Could they be somehow out-of-date? If this is the case, is there some way to "update" the .browser files? I'm half-tempted to just copy the .browser files out of the Framework directory from my machine over to theirs, but I'm curious is there's something more formal than this? Is there some other source of data that ASP.Net uses for browser detection other than these files?

• C++ & proper TDD

  - by Kotti

  Hi! I recently tried developing a small-sized project in C# and during the whole project our team used the Test-Driven-Development (TDD) technique (xunit, moq). I really think this was awesome, because (when paired with C#) this approach allowed to relax when coding, relax when projecting and relax when refactoring. I suspect that all this TDD-stuff actually simplifies the coding process and, well, it allowed (eventually, for me) to get the same result with fewer brain cells working. Right after that I tried using TDD paired with C++ (I used Google Test and Google Mock libraries), and, I don't know why but I actually think that TDD here was a step back in terms of rapid application development. I had some moments when I had to spend huge amounts of time thinking of my tests, building proper mocks, rebuilding them and swearing at my monitor. And, well, I obviously can't ask something like "what I did wrong?" or "what was wrong in my approach?", because I don't know what to describe. But if there are any people who are used to TDD in C++ (and, probably C#) too, could you please advise me how to do this properly. Framework recommendations, architecture approaches, plain coding advices - if you are experienced in TDD & C++, please respond.

• Migrate Data and Schema from MySQL to MSSQL

  - by colithium

  Are there any free solutions for automatically migrating a database from MySQL to MSSQL Server that "just works"? I've been attempting this simple (at least I thought so) task all day now. I've tried: MSSQL Server Management Studio's Import Data feature Create an empty database Tasks - Import Data... .NET Framework Data Provider for Odbc Valid DSN (verified it connects) Copy data from one or more tables or views Check 1 VERY simple table Click Preview Get Error: The preview data could not be retrieved. ADDITIONAL INFORMATION: ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.1.45-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"table_name"' at line 1 (myodbc5.dll) A similar error occurs if I go through the rest of the wizard and perform the operation. The failed step is "Setting Source Connection" the error refers to retrieving column information and then lists the above error. It can retrieve column information just fine when I modify column mappings so I really don't know what the issue is. I've also tried getting various MySql tools to output ddl statements that MSSQL understand but haven't succeeded. I've tried with MySQL v5.1.11 to SQL Server 2005 and with MySQL v5.1.45 to SQL Server 2008 (with ODBC drivers 3.51.27.00 and 5.01.06.00 respectively)

• My first MVVM application architecture setup

  - by 1110

  Ok, time is coming for my first WPF project :). I work before with Flex and PureMVC and I know how project setup is important in RIA's. I decided to work with MVVM. And decided to work with PRISM framework. Application is somethin like operating system. There will be 'shell' (parent for smaller applications). Smaller application I plan to make like modules. So I plan to design structure of project something like this. Module_A {view, viewModel, model, assets} // for example calculator Module_B {view, viewModel, model, assets} // notebook etc I read prism doc and I see that parrent for all this modules should be shell project, and this is my main question here. Parrent_Project {App.xaml, Bootstrapper.cs, Shell.xaml} Because this shell will be fullscreen with background images (like operating system), right click with some features. Is that ok to create folder structure like in modulesXYZ for Shell.xaml here? I want to start project with good structure so any advice is welcome. Thanks

• 960 GridSystem, three grid_4 inside one grid_12

  - by Olle

  I've created a 16 column layout with 960gs with a div class="grid_12" and after that a grid_4 (12+4...) Inside that grid_12 I wanted a three column style (3 grid_4). But the grid_4 boxes don't fit inside the grid_12, the last box drop into a second row. Shouldn't the 960gs framework be able to do this layout for me, have i missed anything? Thanks in advance. <div class="container_16"> ... <div id="main" class="grid_12"> <div class="grid_12"> <div class="grid_4"></div> <div class="grid_4"></div> <div class="grid_4"></div> </div> <div id="right" class="grid_4"> </div> </div> ... </div>

• How do common web frameworks (Django, Rails, Symfony, etc) handle multiple instances of the same plu

  - by Steven Wei

  Do any of the popular web frameworks solve this problem well? Here's an example: suppose you're running one of these web frameworks and you want to install a blog plugin. Except instead of a single blog, you need to run two separate instances of the blog plugin, and you want to keep them segregated. Or say you want to install multiple instances of a user authentication plugin, because you want to segregate your administrative users from your customer user accounts. Or say you want to install multiple instances of a wiki plugin for different parts of your site, or multiple instances of a comments plugin, or whatever else. It seems to me that at the basic level, each instance of plugin would need to be able to configured with a different set of database tables, and would need to be 'installed' at a different URL path. My experience is mostly with Django and Symfony, and I haven't seen a clean solution to this problem in either of them. They both tend to assume that each plugin (or app, in Django's case) is only ever going to be installed once. I'm curious if the Rails folks have figured out a clean solution to this problem, or any other framework authors (in any language). And if you were going to design a solution to this problem, what would it look like?

• routing mvc on the web

  - by generic_noob

  Hi, I was wondering if anyone could possibly provide me some advice on how i could improve the routing (and/or architecture) to each 'section' of my application. (I'm writing in PHP5, and trying to use strict MVC) Basically, I have a generic index page for the app, and that will spew out boilerplate stuff like jquery and the css etc. and it also generates the main navidation for the entire site, but i'm unsure about the best approach to connect the 'main menu' items(hyperlinks) with their associated controllers. Up until now I have been appending strings into the url and using a 'switch' statement to branch to the correct controller(and view) by extracting the strings back out of '$GET[]' to let it execute the code for the corrosponding action. for instance if i had a basic crud system for customer data, the url to edit a customers details would look like 'www.example.com/index.php?page=customer&action=edit&id=4'. I'm worried that there is a security concern by doing it this way, and i'm not sure of an alternative to branch the main 'index.php' file to the correct controller for each action once the user has clicked the link. Would it be better to use mod_rewrite to disguise the controllers names? or to create a similar system to the ASP MVC framework, where there is a seperate routing system where each url is filtered to get the associated controller? Cheers!

• Play Multiple iPod Library Songs On iPhone At The Same Time With Pitch Bending & Other Effects

  - by Dino

  Hi, I have been going at this for the past two weeks and it is driving me crazy. I asked this question a couple of days ago (Extract iPod Library raw PCM samples and play with sound effects) and whilst the answer got me half way there I am still stuck. Basically what I am trying to achieve is load up multiple songs from the iPod library for playback with effects such as pitch bend, eq effects etc... I have gone down the route of AVPlayer and AVAudioPlayer which are too simple. The only framework I've seen that can play audio with these effects is OpenAL. I have tried a few objective c wrappers (Finch and ObjectAL) Finch does not play compressed audio whilst ObjectAL will only convert it for me if I pass in a URL for the file (which is something I cannot do because I only have an incompatible iPod library URL). An example of an app that does what I want beautifilly is Tap DJ. It can load up songs from the iPod library fast (unlike TouchDJ and it plays them with all sorts of effects. Any help would be much appreciated.

• Something about Stream

  - by sforester

  I've been working on something that make use of streams and I found myself not clear about some stream concepts( you can also view another question posted by me at http://stackoverflow.com/questions/2933923/about-redirected-stdout-in-system-diagnostics-process ). 1.how do you indicate that you have finished writing a stream, writing something like a EOF? 2.follow the previous question, if I have written a EOF(or something like that) to a stream but didn't close the stream, then I want to write something else to the same stream, can I just start writing to it and no more set up required? 3.if a procedure tries to read a stream(like the stdin ) that no one has written anything to it, the reading procedure will be blocked,finally some data arrives and the procedure will just read till the writing is done,which is indicated by getting a return of 0 count of bytes read rather than being blocked, and now if the procedure issues another read to the same stream, it will still get a 0 count and return immediately while I was expecting it will be blocked since no one is writing to the stream now. So does the stream holds different states when the stream is opened but no one has written to it yet and when someone has finished a writing session? I'm using Windows the .net framework if there will by any thing platform specific. Thanks a lot!

• Extracting function declarations from a PHP file

  - by byronh

  I'm looking to create an on-site API reference for my framework and application. Basically, say I have a class file model.class.php: class Model extends Object { ... code here ... // Separates results into pages. // Returns Paginator object. final public function paginate($perpage = 10) { ... more code here ... } } and I want to be able to generate a reference that my developers can refer to quickly in order to know which functions are available to be called. They only need to see the comments directly above each function and the declaration line. Something like this (similar to a C++ header file): // Separates results into pages. // Returns Paginator object. final public function paginate($perpage = 10); I've done some research and this answer looked pretty good (using Reflection classes), however, I'm not sure how I can keep the comments in. Any ideas? EDIT: Sorry, but I want to keep the current comment formatting. Myself and the people who are working on the code hate the verbosity associated with PHPDocumentor. Not to mention a comment-rewrite of the entire project would take years, so I want to preserve just the // comments in plaintext.

• Which frameworks (and associated languages) support class replacement?

  - by Alix

  Hi, I'm writing my master thesis, which deals with AOP in .NET, among other things, and I mention the lack of support for replacing classes at load time as an important factor in the fact that there are currently no .NET AOP frameworks that perform true dynamic weaving -- not without imposing the requirement that woven classes must extend ContextBoundObject or MarshalByRefObject or expose all their semantics on an interface. You can however do this with the JVM thanks to ClassFileTransformer: You extend ClassFileTransformer. You subscribe to the class load event. On class load, you rewrite the class and replace it. All this is very well, but my project director has asked me, quite in the last minute, to give him a list of frameworks (and associated languages) that do / do not support class replacement. I really have no time to look for this now: I wouldn't feel comfortable just doing a superficial research and potentially putting erroneous information in my thesis. So I ask you, oh almighty programming community, can you help out? Of course, I'm not asking you to research this yourselves. Simply, if you know for sure that a particular framework supports / doesn't support this, leave it as an answer. If you're not sure please don't forget to point it out. Thanks so much!

• VS2010 error: Unable to start debugging on the web server

  - by GarDavis

  I get error message "Unable to start debugging on the web server" in Visual Studio 2010. I clicked the Help button and followed the related suggestions without success. This happens with a newly created local ASP.Net project when modified to use IIS instead of Cassini (which works for debugging). It prompts to set debug="true" in the web.config and then immediately pops up the error. Nothing shows up in the Event Viewer. I am able to attach to w3wp to debug. It works but is not as convenient as F5. I also have a similar problem with VS2008 on the same PC. Debugging used to work for both. I have re-registered Framework 4 (aspnet_regiis -i). I ran the VS2010 repair (this is the RTM version). I am running on a Windows Server 2008 R2 x64 box. I do have Resharper V5 installed. There must be some configuration setting or registry value that survives the repair causing the problem. I'd appreciate any ideas. Thanks, Gary Davis ([email protected])

• SOAP web services in haskell?

  - by Dave

  I have to write a bunch of small web services. They must be defined by a WSDL and work via SOAP-RPC, in order to work with an existing workflow engine and service registry framework. I can, however, serve them on a service stack/platform of my choice. I'm presently writing them in Java, and it's not too bad. But I'm thinking my life might be easier if I was able to write these services in Haskell. Searching on Google, it looks like, once upon a time, someone else had the same idea and started a project called "HAIFA". However, it looks like HAIFA hasn't been maintained for some years, and I couldn't find any other frameworks supporting serving up services written in Haskell as SOAP web services. Does anyone know of any other frameworks that will allow me to easily write SOAP-based web services using Haskell? If not, has anyone done this manually (i.e., use XML libraries from hackage to process the incoming soap-rpc requests, and create soap-rpc compliant replies)? Was it difficult to do? Any gotchas? Was it worth the effort? Thanks in advance!

• return only the last select results from stored procedure

  - by Madalina Dragomir

  The requirement says: stored procedure meant to search data, based on 5 identifiers. If there is an exact match return ONLY the exact match, if not but there is an exact match on the not null parameters return ONLY these results, otherwise return any match on any 4 not null parameters... and so on My (simplified) code looks like: create procedure xxxSearch @a nvarchar(80), @b nvarchar(80)... as begin select whatever from MyTable t where ((@a is null and t.a is null) or (@a = t.a)) and ((@b is null and t.b is null) or (@b = t.b))... if @@ROWCOUNT = 0 begin select whatever from MyTable t where ((@a is null) or (@a = t.a)) and ((@b is null) or (@b = t.b))... if @@ROWCOUNT = 0 begin ... end end end As a result there can be more sets of results selected, the first ones empty and I only need the last one. I know that it is easy to get the only the last result set on the application side, but all our stored procedure calls go through a framework that expects the significant results in the first table and I'm not eager to change it and test all the existing SPs. Is there a way to return only the last select results from a stored procedure? Is there a better way to do this task ?

• Limit TCP requests per IP

  - by asmo

  Hello! I'm wondering how to limit the TCP requests per client (per specific IP) in Java. For example, I would like to allow a maximum of X requests per Y seconds for each client IP. I thought of using static Timer/TimerTask in combination with a HashSet of temporary restricted IPs. private static final Set<InetAddress> restrictedIPs = Collections.synchronizedSet(new HashSet<InetAddress>()); private static final Timer restrictTimer = new Timer(); So when a user connects to the server, I add his IP to the restricted list, and start a task to unrestrict him in X seconds. restrictedIPs.add(socket.getInetAddress()); restrictTimer.schedule(new TimerTask() { public void run() { restrictedIPs.remove(socket.getInetAddress()); } }, MIN_REQUEST_INTERVAL); My problem is that at the time the task will run, the socket object may be closed, and the remote IP address won't be accessible anymore... Any ideas welcomed! Also, if someone knows a Java-framework-built-in way to achieve this, I'd really like to hear it.

• Best practices for withstanding launch day traffic burst

  - by Sam McAfee

  We are working on a website for a client that (for once) is expected to get a fair amount of traffic on day one. There are press releases, people are blogging about it, etc. I am a little concerned that we're going to fall flat on our face on day one. What are the main things you would look at to ensure (in advance without real traffic data) that you can stay standing after a big launch. Details: This is a L/A/M/PHP stack, using an internally developed MVC framework. This is currently being launched on one server, with Apache and MySQL both on it, but we can break that up if need be. We are already installing memcached and doing as much PHP-level caching as we can think of. Some of the pages are rather query intensive, and we are using Smarty as our template engine. Keep in mind there is no time to change any of these major aspects--this is the just the setup. What sorts of things should we watch out for?

• Call a dynamically generated method on a ILGenerator on the same type

  - by Thiado de Arruda

  Normally, when I want to call a dynamic method in another ILGenerator object that is writing a method on the same type I do the following : generator.Emit(OpCodes.Ldarg_0); // reference to the current object generator.Emit(OpCodes.Ldstr, "someArgument"); generator.Emit(OpCodes.Call, methodBuilder); //this methodbuilder is also defined on this dynamic type. However, I faced the following problem: I cant have a reference to the methodbuilder of the method I want to call, because it is generated by another framework(I only get a reference to the current TypeBuilder). This method is defined as protected virtual(and overriden on the methodbuilder I cant get a reference to) in the base class of the current dynamic type and I can get a reference to it by doing this : generator.Emit(OpCodes.Ldarg_0); // reference to the current object generator.Emit(OpCodes.Ldstr, "someArgument"); generator.Emit(OpCodes.Call, baseType.GetMethod("SomeMethodDefinedInBaseClassThatWasOverridenInThisDynamicType")); The problem is that this calls the method on the base type and not the overriden method. Is there any way I can get a reference to a methodbuilder only having a reference to the typebuilder that defined it? Or is there a way to call a method using ILGenerator without having to pass the 'MethodInfo' object to it?

• What is the corrrect way to increment a field making up part of a composit key

  - by Tr1stan

  I have a bunch of tables whose primary key is made up of the foreign keys of other tables (Composite key). Therefore for example the attributes (as a very cut down version) might look like this: A[aPK, SomeFields] 1:M B[bPK, aFK, SomeFields] 1:M C[cPK, bFK, aFK, SomeFields] as data this could look like: A[aPK, SomeFields]: 1, Foo 2, Bar B[bPK, aFK, SomeFields]: 1, 1, FooData1 2, 1, FooData2 1, 2, BarData1 2, 2, BarData2 C[cPK, bFK, aFK, SomeFields]: 1, 1, 1, FooData1More 2, 1, 1, FooData1More 1, 2, 1, FooData2More 2, 2, 1, FooData2More 1, 1, 2, BarData1More 2, 1, 2, BarData1More 1, 2, 2, BarData2More 2, 2, 2, BarData2More I've got this running in a MSSQL DBMS and I'm looking for the best way to increment the left most column, in each table when a new tuple is added to it. I can't use the Auto Increment Identity Specification option as that has no idea that it is part of a composite key. I also don't want to use any aggregate function such as: MAX(field)+1 as this will have adverse affects with multiple users inputting data, rolling back etc. There might however be a nice trigger based option here, but I'm not sure. This must be a common issue so I'm hoping that someone has a lovely solution. As a side which may or may not affect the answer, I'm using Entity Framework 1.0 as my ORM, within a c# MVC application.

• Artisan unable to access environment variables from $_ENV

  Any artisan command I enter into the command line throws this error: $ php artisan <? return array( 'DB_HOSTNAME' => 'localhost', 'DB_USERNAME' => 'root', 'DB_NAME' => 'pc_booking', 'DB_PASSWORD' => 'secret', ); PHP Warning: Invalid argument supplied for foreach() in /home/martin/code/www/pc_backend/vendor/laravel/framework/src/Illuminate/Config/EnvironmentVariables.php on line 35 {"error":{"type":"ErrorException","message":"Undefined index: DB_HOSTNAME","file":"\/home\/martin\/code\/www\/pc_backend\/app\/config\/database.php","line":57}} This is only on my local development system, where I recently installed apache and php. On my production system on a shared host artisan commands work just fine. The prod system has it's own .env.php, but other than that the code should be identical.

• How to resolve the only ImagePicker control view in landscap mode and whole application in portrait mode?

  - by Wolvorin

  I have tried almost all the answers during last two days provided by Google and SO but no luck :( What I want is my whole application is in portrait mode only. And it working fine in ios 6+. The only support required at now. But the problem is I need to launch UIImagePickerViewController with image source type camera in only landscap mode. What I tried till now is : (1) I try to create one category for UIImagePickerController for orientation. -(BOOL)shouldAutorotate { return NO; } -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskLandscape; } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { return UIInterfaceOrientationLandscapeLeft; } Like this. But the camera view is not proper aligned. It just follows the orientation of device with some +/- 90 angle but not what I required. Even the button of the camera shown by camera view as camera control is also follows the camera view, ie. the view is rotated to 90 anti clock vise and stays to that way. Is there any way to use the camera with proper alignment? or have to use other framework to work with it? Please help me. I stuck with it for last two days.

• Zend Partial + Zend Action Helper causes an additional request to bootstrap?

  - by AndreLiem

  I've been profiling some zend framework code with webgrind to see where some bottle necks are and I'm noticing some very odd behavior. Using the zend partial for example, if I pass a variable value that comes from a zend action helper, it results in two requests being made. in sample.phtml echo $this->partial('partial/embed.phtml', array('url' => $this->url)); in indexcontroller.php $this->view->url = $this->_helper->Embed()->url; But if I don't pass the value from the helper to the partial, but still run the helper, it only makes one request in webgrind. e.g. $this->view->url = 'test'; $this->_helper->Embed()->url; Does anybody know why this could be happening? Am I potentially interpreting web grind incorrectly, or is it really calling the bootstrap twice when the an action helper value is tied to a partial? I'm starting to realize how inefficient some components of Zend are. Thanks

• asp.net webpages content block and helper differences

  - by metanaito

  In asp.net webpages framework what is the difference between using a content block versus a helper? They both seem to be used to output HTML to multiple pages. They both can contain code and both can pass parameters. Are there other differences? When should you use a helper versus a content block? More info: With Content Blocks we create a .cshtml (for example _MakeNote.cshtml) file to hold the content we want to insert into a page. Then we use: @RenderPage("/Shared/_MakeNote.cshtml") to insert the content into a page. We can pass parameters to the content block like this: @RenderPage("/Shared/_MakeNote.cshtml", new { content = "hello from content block" }) It's somewhat like an include file, but I think does not share scope with the parent page. With Helpers we create a .cshtml page in the App_Code folder (for example MyHelpers.cshtml) and place methods in that page which we want to call. The method looks something like this: @helper MakeNote(string content) { <div>@content</div> } The helper is called by using: @MyHelpers.MakeNote("Hello from helper")
