• How to mock a RIA service

  - by Budda

  Is there any ability to mock methods that are provided with RIA Services? I would like to test my Silverlight App without communication to the server side... I see a following approach: create a separate interface; add it to "base classes" for my RiaService; define each autogenerated RIA-method in this interface; insert dependency so that my "functionality" will depend not from the RiaService, but from the interface that is implemented with RiaService. But for this case I see a problem: how to keep my interface in the auto-generated files? ANy thoughts are welcome.

• Update configSource of XML element in web.config using Powershell by passing in Parameters

  - by Howard

  I am trying to figure out a way to update my web.config for different environments by updating the configSource for the appSettings element in the web.config. Here are the way I know how to do it. $xml.get_DocumentElement().appSettings.configSource = $replaced_test The problem is that I want one base script where I can pass in different nodes to the script that I want to change and update but I am not sure how to do it. For example, I want to be able to call a powershell script like this changeWebConfig.ps1 nodeToChange newValueofNode I hope this was clear enough. This is the code I have now. $webConfigPath = "C:\web.config" # Get the content of the config file and cast it to XML $xml = [xml](get-content $webConfigPath) #this was the trick I had been looking for $root = $xml.get_DocumentElement()."system.serviceModel".client.configSource = $replace # Save it $xml.Save($webConfigPath)

• [WPF] SelectionChanged of a child ListBox

  - by quimbs

  Hi, I have a ListBox bound to an ObservableCollection with an ItemTemplate that contains another ListBox. First of all, I tried to get the last selected item of all the listboxes (either the parent and the inner ones) from my MainWindowViewModel this way: public object SelectedItem { get { return this.selectedItem; } set { this.selectedItem = value; base.NotifyPropertyChanged("SelectedItem"); } } So, for example, in the DataTemplate of the items of the parent ListBox I've got this: <ListBox ItemsSource="{Binding Tails}" SelectedItem="{Binding Path=DataContext.SelectedItem, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"/> The problem now, is that when I select an item from the parent ListBox and then an item from a child listbox, I get this: http://i40.tinypic.com/j7bvig.jpg As you can see, two items are selected at the same time. How can I solve that? Thanks in advance.

• Overriding Constructors in F#

  - by kim3er

  How would I write the following C# code in F#? namespace Shared { public class SharedRegistry : PageRegistry { public SharedRegistry(bool useCache = true) : base(useCache) { // Repositories ForRequestedType<IAddressRepository>().TheDefaultIsConcreteType<SqlAddressRepository>(); ForRequestedType<ISharedEnquiryRepository>().TheDefaultIsConcreteType<SharedEnquiryRepository>(); // Services ForRequestedType<IAddressService>().TheDefaultIsConcreteType<AddressService>(); ForRequestedType<ISharedEnquiryService>().TheDefaultIsConcreteType<SharedEnquiryService>(); } } } As is as far as I have managed, but I can't work out to inherit from PageRegistry at the same time as declaring my own default constructor. type SharedRegistry(useCache: bool) = inherit PageRegistry(useCache) new() = new SharedRegistry(true) Rich

• Flex TileList control, image loading issue

  - by ckenan

  I have a flex 3 TileList in wich a load several image (employee's headshot pictures). The image I'm loading in the TileList are stored in a DataBase (I use the ByteArray class and a Base 64 encoding to store the images in the DB). When I load the images in the TileList from the DB, there is no problem they are displayed correctly, but when I scroll down in the TileList and scroll up again, the position of the images is changing, so for example the image in first position can be now in the 3rd and so on .... Does somebody knows how to fix that ? Thanks in advance! PS : Here is the code of the ItemRenderer for the TileList private function init():void { img.load(data.imageData); } ]]

• ASP.NET MVC ,Maintaining Model State between Ajax requests

  - by Podders

  problem: On first full page request, my controller invokes an applicationServices Layer (Web Service Proxy to my business tier) in order to populate a collection of current services that is stored in my own controller base class property. This is then to be displayed within a view. Everything within the context of that controller has access to this "Services Collection". Now when i make further calls to the same action method via an AJAX Call, i obviously hitt a different instance of that controller meaning my services collection is empty. So other than re-getting the whole collection again, where would i store this collection so it gets persisted between ajax requests? Should i persist it as a seperate DomainModel Object, Session object?....as ViewData is not working for me obv. Excuse my MVC ignorance :) Any help would be greatly appreciated :)

• Intellij-Idea: Marking all files of unknown type as text (so that they are searchable)

  - by sixtyfootersdude

  Many of my scripts etc in intellij are marked with a question mark. Then when I click on them them it prompts me: The file "bla" cannot be associated with a registered file type. Please choose one: <insert table of file choices> This would not matter except the files are not searchable (with ctrl-shift-n) until they are marked as text. This is a major problem for me. I have an enormous code base and I don't want to mark all of the unknown files as text. Is there anyway that I can do that?

• Why isn't this MVC Html Helper extension method working?

  - by Blankman

  My base controller looks like: public abstract MyBaseMasterController<TMasterViewModel> : Controller { } public MyMasterController: MyBaseMasterController<SomeThingModel> { } Extension method: public static string DoSomething(this HtmlHelper htmlHelper) { StringBuilder sb = new StringBuilder(); sb.Append("var cnwglobals = {"); var controller = htmlHelper.ViewContext.Controller as MyMasterController; if (controller == null) { } return sb.ToString(); } In my view I do: <% Html.Dosomething(); %> I get an error: CS1061: 'System.Web.Mvc.HtmlHelper<Blah.Models.ViewModelForMasterWrapper<Blah.Models.MasterViewModel>>' does not contain a definition for 'DoSomething' and no extension method 'DoSomething' accepting a first argument of type 'System.Web.Mvc.HtmlHelper<Blah.Models.ViewModelForMasterWrapper<Blah.Models.MasterViewModel>>' could be found (are you missing a using directive or an assembly reference?)

• Access current_user in model

  - by LearnRails

  I have 3 tables items (columns are: name , type) history(columns are: date, username, item_id) user(username, password) When a user say "ABC" logs in and creates a new item, a history record gets created with the following after_create filter. How to assign this username ‘ABC’ to the username field in history table through this filter. class Item < ActiveRecord::Base has_many :histories after_create :update_history def update_history histories.create(:date=Time.now, username= ?) end My login method in session_controller def login if request.post? user=User.authenticate(params[:username]) if user session[:user_id] =user.id redirect_to( :action='home') flash[:message] = "Successfully logged in " else flash[:notice] = "Incorrect user/password combination" redirect_to(:action="login") end end end I am not using any authentication plugin. I would appreciate if someone could tell me how to achieve this without using plugin(like userstamp etc.) if possible.

• What open source database platform is most easily transferred from my personal machine into a window

  - by Tom

  I would like eventual interaction with MS Dynamics SL and/or MindTouch Core (running on WMware) for eventual intranet and/or internet display. I guess I am asking for front and back end recommendations for a database I am constructing, but since this is my first major project I would greatly appreciate any help and advice. I would also love an opportunity to learn a new language so the code base could be in any language. I do have a few more related questions for discussion; What is the viability of using Google hosting to provide the service to the public for free? Should I implement plone or another CMS if I have a large amount of output? Is there a structuring questionnaire or standards publication I could reference? Does UML diagramming provide additional options for portability? Thank you.

• How to detect code duplication during development ?

  - by David Dibben

  We have a fairly large code base, 400K LOC of C++, and code duplication is something of a problem. Are there any tools which can effectively detect duplicated blocks of code? Ideally this would be something that developers could use during development rather than just run occasionally to see where the problems are. It would also be nice if we could integrate such a tool with CruiseControl to give a report after each check in. I had a look at Duploc some time ago, it showed a nice graph but requires a smalltalk environment to use it, which makes running it automatically rather difficult. Free tools would be nice, but if there are some good commercial tools I would also be interested.

• "The left hand side of an assignment must be a variable" due to extra parentheses

  - by polygenelubricants

  I know why the following code doesn't compile: public class Main { public static void main(String args[]) { main((null)); // this is fine! (main(null)); // this is NOT! } } What I'm wondering is why my compiler (javac 1.6.0_17, Windows version) is complaining "The left hand side of an assignment must be a variable". I'd expect something like "Don't put parentheses around a method invokation, dummy!", instead. So why is the compiler making a totally unhelpful complaint about something that is blatantly irrelevant? Is this the result of an ambiguity in the grammar? A bug in the compiler? If it's the former, could you design a language such that a compiler would never be so off-base about a syntax error like this?

• How to use DAOs with hibernate/jpa?

  - by Ari

  Assuming the DAO structure and component interaction described below, how should DAOs be used with persistence layers like hibernate and toplink? What methods should/shouldn't they contain? Would it be bad practice to move the code from the DAO directly to the service? For example, let's say that for every model we have a DAO (that may or may not implement a base interface) that looks something like the following: public class BasicDao<T> { public List<T> list() { ... } public <T> retrieve() { ... } public void save() { ... } public void delete() { ... } } Component interaction pattern is -- service DAO model

• Android: Registering ContextMenu for a Custom ListAdapter

  - by primal

  Hi, I made a custom list adapter extending the Base adapter. Each item in the list has an imagebutton, 2 textviews and a button. I tried to add the context menu to the list so as to display some options for an item in the list. registerForContextMenu(getListView()); I used a MenuInflater object to inflate the context menu xml file. But on clicking the items in the list nothing shows up or the usual highlighting of the item of list on click isn't shown. Is it that the context menu doesn't work for custom list views? Any help would be much appreciated. Regards, Primal

• ZeroC Ice "checked casts" in Scala

  - by Alexey Romanov

  ZeroC Ice for Java translates every Slice interface Simple into (among other things) a proxy interface SimplePrx and a proxy SimplePrxHelper. If I have an ObjectPrx (the base interface for all proxies), I can check whether it actually has interface Simple by using a static method on SimplePrxHelper: val obj : Ice.ObjectPrx = ...; // Get a proxy from somewhere... val simple : SimplePrx = SimplePrxHelper.checkedCast(obj); if (simple != null) // Object supports the Simple interface... else // Object is not of type Simple... I wanted to write a method castTo so that I could replace the second line with val simple = castTo[SimplePrx](obj) or val simple = castTo[SimplePrxHelper](obj) So far as I can see, Scala's type system is not expressive enough to allow me to define castTo. Is this correct?

• IntelliJ: Adding resources to the class path, but still gives me "java.util.MissingResourceException: Can't find bundle.... locale en_US"

  - by Martin

  I am quite new to intellij and i have loaded in a project that i wish to compile, everything seems to be going well, but when i compile it. I get the bundle cannot be found. java.util.MissingResourceException: Can't find bundle for base name openfire_i18n, locale en_US at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1499) After doing some investigation, it appears i have to include the resources in the class path, is this correct? I have done Project Settings, Modules, Dependencies, and i added a "Jars or directories" There is a checkbox that says Export, i have tried clicking it and unclicking it :-) My resources i can see are in i8n\ResourceBundle I tried adding the i8n and it asked me for a category for selected files, i put classes RUN - but still same error.. so i tried adding the i8n/ResourceBundle directory RUN - still same error. I notice under my ResourceBundle directory there are C:\Dev\Java\openfire_src_3_7_1\openfire_src\src\i18n\openfire_i18n_en.properties but there is no specific en_US but i thought it supposed to fallback to EN ?? SO i think everything is ok. Can anyone help I am really stuck Thanks

• ASP.NET MVC 2 RC 2 returns Area-specific controller when no area specified

  - by Bryan

  I have a basic MVC 2 (RC2) site with one base-level controller ("Home"), and one area ("Admin") with one controller ("Abstract"). When i call http://website/Abstract - the Abstract controller in the Admin area gets called even though i haven't specified the Area in the URL. To make matters worse - it doesn't seem to know it's under Admin because it can't find the associated view and just returns: The view 'Index' or its master was not found. The following locations were searched: ~/Views/Abstract/Index.aspx ~/Views/Abstract/Index.ascx ~/Views/Shared/Index.aspx ~/Views/Shared/Index.ascx Am i doing something wrong? Is this a bug? A feature?

• oAuth provider with Django-piston

  - by Martin Eve

  Hi, I'm working with django-piston to attempt to create an API that supports oAuth. I started out using the tutorial at: http://blog.carduner.net/2010/01/26/django-piston-and-oauth/ I added a consumer to piston's admin interface with key and secret both set to "abcd" for test purposes. The urls are successfully wired-up and the oAuth provider is called. However, running my get request token tests with tripit (python get_request_token.py "http://127.0.0.1:8000/api" abcd abcd), I receive the following error: Invalid signature. Expected signature base string: GET&http%3A%2F%2F127.0.0.1%3A8000%2Fapi%2Foauth%2Frequest_token%2F&oauth_consumer_key%3Dabcd%26oauth_nonce%3D0c0bdded5b1afb8eddf94f7ccc672658%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1275135410%26oauth_version%3D1.0 The problem seems to lie inside the _check_signature method of Piston's oauth.py, where valid_sig = signature_method.check_signature(oauth_request, consumer, token, signature) is returning false. I can't, however, work out how to get the signature validated. Any ideas?

• Turn RSS into array, explode the 'description' and insert words into MySQL table one per row

  - by K.I

  I have only recently gotten into php and MySQL and I want to take an RSS feed, turn it into an array, take only the description part of the XML, explode it and insert it into a table on a MySQL base. I feel like this should be possible, but is a little over my head right now. I tried using magpie as a parser, but if possible I want to do it in simpler php code. The result I am looking for would take a description "This is a cat" and insert it into a table with two fields ID term 1 This 2 is 3 a 4 cat I've been stumped on this for a couple days. Any help would be great.

• Python File Meta Tag reading

  - by Jeff

  Anyone know of a Python module that can pull Tag data from multiple media formats? Trying to build an app that allows for manipulation of ASF (Windows Media Player files, ie WMA, WMV, etc), ID3, including both ID3v1 and ID3v2 (MPEG files, ie MP3), MPEG Audio Bit Stream (ie ABS, MP1, MP2, MP3), MPEG Program Stream (MPEG movies, and DVD and HD DVD video discs, ie MPG, MPEG, VOB, EVO), and ISO Base Media File Format (eg QuickTime, MPEG-4 and iTunes AAC files, ie QT, MOV, MP4, M4A, M4B, M4P, M4V, etc). Don't need ALL of that but just most standard consumer formats like mov and mpeg. I can't seem to find a good module to support that or a library. Any recommendations?

• IntelliSense based snippet handling with Visual Studio 2010 SDK MEF Based text editor

  - by Nicolai Ustinov

  Using the new Visual Studio 2010 SDK developing against the MEF based editor structure there's a question: How can I use the MEF editor interfaces to handle snippet behavior in IntelliSense? The ICompletionSession itself is not a problem (e.g. get the available snippets) rather filling the snippet, handling the subsequently expected actions like tab, enter behavior, text replacement, etc. Is there any way to do that without a language service? Checking the built-in behavior in Visual Studio base editor implementation they built the MEF interfaces on top of a set of language service based objects.

• Load properties file in JAR?

  - by apryor48

  I'm having trouble when one of the jars that my web app depends on tries to load a properties file from within the jar. Here is the code in the jar. static { Properties props = new Properties(); try { props.load(ClassLoader.getSystemResourceAsStream("someProps.properties")); } catch (IOException e) { e.printStackTrace(); } someProperty = props.getProperty("someKey"); } The properties file is in my "src/main/resources" directory of the Maven project. When I run this code from my junit test in Eclipse, it executes just fine. When the project is built with Maven into a jar, and included as a dependency in my webb app, it fails to locate the properties file. I know that the properties file is at the base directory of the depended on jar, I don't know how to fix this. Please help!

• Problems setting up an ASP.NET MVC site on IIS7 w/ Nhibernate

  - by Brandon

  When deploying my published website to the host (Its a shared hosting plan) I get this error: [NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineStepManager.ResumeSteps(Exception error) +929 System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +91 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +508 I found this question which describes my problem, but I'm not initializing NHibernate in Application_Start, it is already being done in Init. The only other cause of this error I can find is that the Global.asax file is inheriting from a class other than HttpApplication, but I'm not doing that either. This is pretty much the Global.asax file protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); } public override void Init() { base.Init(); if (_wasNHibernateInitialized) return; // Initialize NHibernate // Other setup like the StructureMap initialization } Is there any other reason why an ASP.NET MVC application would give this error when being deployed to IIS7?
