    Révision de pré-rentrée : Microsoft a mis en ligne ses cahiers de vacances Sur Visual Studio 2012, Windows Phone, Windows 8, Azure et Windows Server Mea Culpa. Nous aurions pu en parler avant. Mais mieux vaut tard que jamais. D'autant plus que les révisions, c'est bien aussi quand ça ne dure pas toutes les vacances. Quoiqu'il en soit, Microsoft a mis en ligne deux « Cahiers de vacances » pour faire le point, se tester et/ou apprendre à maitrise toutes les nouveautés (et Dieu sait qu'elles sont nombreuses) autour de ses produits. Le premier, « J'en ai rien à déployer », revient sur la RC de Windows Server 2012, et sur la virtualisation av...

  • Virtualbox Kernel driver not installed

    - by Cyndi
    I tried to use my Virtual Box and this is the error I received - (I just updated to the new Ubuntu also) and I am VERY new at this Linux OS :) Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

  • PHP : Symfony sort en version 2.1 définitive, gestion des dépendances avec Composer, formulaires et Mailer plus performants

    Symfony2 est un projet très communautaire, depuis le début (des centaines de bundles étaient disponibles bien avant les premières RC de la 2.0), une tendance qui se confirme : 250 contributeurs, 1 000 pull requests sur GitHub pour la première version beta de Symfony 2.1 ! Après les difficultés de migration avec symfony 1.x, l'équipe a tenté autant que possible de restreindre les changements à même de casser la rétrocompatibilité ; de même, le refactoring du module de formulaires a fait que la version finale de la 2.1 devrait sortir en août, afin de concentrer autant que possible les changements et faire que de plus en plus de code ne devra pas être modifié lors de la migration d'une version à l'autre. Ainsi, n'hésitez pas à tenter de migrer vos applications vers cette beta,...

  • Top-Rated JavaScript Blogs

    - by Andreas Grech
    I am currently trying to find some blogs that talk (almost solely) on the JavaScript Language, and this is due to the fact that most of the time, bloggers with real life experience at work or at home development can explain more clearly and concisely certain quirks and hidden features than most 'Official Language Specifications' Below find a list of blogs that are JavaScript based (will update the list as more answers flow in): DHTML Kitchen, by Garrett Smith Robert's Talk, by Robert Nyman EJohn, by John Resig (of jQuery) Crockford's JavaScript Page, by Douglas Crockford Dean.edwards.name, by Dean Edwards Ajaxian, by various (@Martin) The JavaScript Weblog, by various SitePoint's JavaScript and CSS Page, by various AjaxBlog, by various Eric Lippert's Blog, by Eric Lippert (talks about JScript and JScript.Net) Web Bug Track, by various (@scunliffe) The Strange Zen Of JavaScript , by Scott Andrew Alex Russell (of Dojo) (@Eran Galperin) Ariel Flesler (@Eran Galperin) Nihilogic, by Jacob Seidelin (@llimllib) Peter's Blog, by Peter Michaux (@Borgar) Flagrant Badassery, by Steve Levithan (@Borgar) ./with Imagination, by Dustin Diaz (@Borgar) HedgerWow (@Borgar) Dreaming in Javascript, by Nosredna spudly.shuoink.com, by Stephen Sorensen Yahoo!

  • MEF Property Export with PartCreationPolicy

    - by Daniel Skinner
    When I try to do this: [Export(typeof(IMyService))] [PartCreationPolicy(CreationPolicy.Shared)] private MyService Service { get { var service = new MyService(); service.Configure(); return service; } } I get a compile error: Attribute 'PartCreationPolicy' is not valid on this declaration type. It is only valid on 'class' declarations. Is this a bug? I don't see why MEF would allow property exports but not allow one to specify the part lifetime. Using VS2010 RC.

  • ASP.NET MVC 2 JQuery POST not displaying the model state errors

    - by Oshan
    Hello, I have been using asp.net mvc for a bit (but I'm still a beginer). I want to have the ability to update two views as a result of a jquery postback. Basically I have a list and a details view. The details view is presented using a jquery popup (using jquery-UI popup). I only want to update the list if the details save is successful (i.e. there are no validation errors on the details view). However, if there are any validation errros in the details view, I want to update the details view so that the user sees the validation errors. so I thought in my controller, I return a JsonResult instead of a View. [HttpPost] public ActionResult SavePersonInfo(Person p) { if(ModelState.Valid) { return View("PersonList"); } return Json({Error = true, View = PartialView("PersonDetails", p)}); } As you can see if there are no errors I return the person list view, but if there are any validation errors, I have return the details view. The reason that I'm returning a JsonResult is I need to tell my view there is an error so that the view (jquery) knows which section to update (as in whether to update the person list 'div' or the popup dialog 'div'). So, in my view, the jquery is as follows (please assume that there is a form for entering in the person details and "SubmitPersonForm();" function is called upon clicking on the "Save" button): <script type="text/javascript> $('#btnSave').click(function (event) { onBegin(); $.ajax( { type: "POST", url: "/Person/Save", data: $('form').serialize(), success: function (result) { if(result.Error) { $('#dvDetails').html($(result).View)); } else { $('#dvPersonList').html($result); } } }); }); </script> So the problem that I have now, is that when there is a validation error, I do see the correct, 'div' being updated, but I lose the asp.net mvc validation messages. I do not see any validation errors in red, as if ASP.NET MVC is completely ignored them. However, my ModelState does have those errros, just not displayed in the details view. I do have valication summary and Html.ValidationFor(m = ...) statements put in my details view. Could someone tell me why I'm not seeing the validation errors? although I'm using a JSonResult, I do use the right property which is a valid view when I render the 'dvDetails'. Am I doing something that I'm not suppose to in asp.net mvc? Btw I'm using asp.net mvc2 RC with Visual Studio 2010 RC. Thank you.

  • Reset VS2010 Project Templates?

    - by Jimbo Jones
    I installed Blend 4 RC recently but strangely it deleted some of my VS2010 projects templates, including the most important ones being Silverlight User Control and Silverlight Application. Does anybody know how to get back these templates or tell VS2010 to reset all templates? A bit frustrating, I'm having to create projects on my laptop then copy them to my desktop manually :(

  • RuntimeBinderException with dynamic in C# 4.0

    - by Terence Lewis
    I have an interface: public abstract class Authorizer<T> where T : RequiresAuthorization { public AuthorizationStatus Authorize(T record) { // Perform authorization specific stuff // and then hand off to an abstract method to handle T-specific stuff // that should happen when authorization is successful } } Then, I have a bunch of different classes which all implement RequiresAuthorization, and correspondingly, an Authorizer<T> for each of them (each business object in my domain requires different logic to execute once the record has been authorized). I'm also using a UnityContainer, in which I register various Authorizer<T>'s. I then have some code as follows to find the right record out of the database and authorize it: void Authorize(RequiresAuthorization item) { var dbItem = ChildContainer.Resolve<IAuthorizationRepository>() .RetrieveRequiresAuthorizationById(item.Id); var authorizerType = type.GetType(String.Format("Foo.Authorizer`1[[{0}]], Foo", dbItem.GetType().AssemblyQualifiedName)); dynamic authorizer = ChildContainer.Resolve(type) as dynamic; authorizer.Authorize(dbItem); } Basically, I'm using the Id on the object to retrieve it out of the database. In the background NHibernate takes care of figuring out what type of RequiresAuthorization it is. I then want to find the right Authorizer for it (I don't know at compile time what implementation of Authorizer<T> I need, so I've got a little bit of reflection to get the fully qualified type). To accomplish this, I use the non-generic overload of UnityContainer's Resolve method to look up the correct authorizer from configuration. Finally, I want to call Authorize on the authorizer, passing through the object I've gotten back from NHibernate. Now, for the problem: In Beta2 of VS2010 the above code works perfectly. On RC and RTM, as soon as I make the Authorize() call, I get a RuntimeBinderException saying "The best overloaded method match for 'Foo.Authorizer<Bar>.Authorize(Bar)' has some invalid arguments". When I inspect the authorizer in the debugger, it's the correct type. When I call GetType().GetMethods() on it, I can see the Authorize method which takes a Bar. If I do GetType() on dbItem it is a Bar. Because this worked in Beta2 and not in RC, I assumed it was a regression (it seems like it should work) and I delayed sorting it out until after I'd had a chance to test it on the RTM version of C# 4.0. Now I've done that and the problem still persists. Does anybody have any suggestions to make this work? Thanks Terence

  • Metro UsernameToken Policy

    - by Rodney
    I created a web services client prototype using api's available in weblogic 10.3. I've been told I need to use Metro 2.0 instead (it's already being used for other projects). The problem I have encounter is that the WSDL does not include any Security Policy information but a UsernameToken is required for each method call. In weblogic I was able to write my own policy xml file and instantiate my service with it (see below), however I can not seem to figure out how to do the same using Metro. Policy.xml <?xml version="1.0"?> <wsp:Policy xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:sp="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200512"> <sp:SupportingTokens> <wsp:Policy> <sp:UsernameToken sp:IncludeToken="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200512/IncludeToken/AlwaysToRecipient"> <wsp:Policy> <sp:WssUsernameToken10/> <sp:HashPassword/> </wsp:Policy> </sp:UsernameToken> </wsp:Policy> </sp:SupportingTokens> </wsp:Policy> Client.java (Weblogic) ClientPolicyFeature cpf = new ClientPolicyFeature(); InputStream asStream = WebServiceSoapClient.class.getResourceAsStream("Policy.xml"); cpf.setEffectivePolicy(new InputStreamPolicySource(asStream)); try { webService = new WebService(new URL("http://192.168.1.10/WebService/WebService.asmx?wsdl"), new QName("http://testme.com", "WebService")); } catch ( MalformedURLException e ) { e.printStackTrace(); } WebServiceSoap client = webService.getWebServiceSoap(new WebServiceFeature[] {cpf}); List<CredentialProvider> credProviders = new ArrayList<CredentialProvider>(); String username = "user"; String password = "pass"; CredentialProvider cp = new ClientUNTCredentialProvider(username.getBytes(), password.getBytes()); credProviders.add(cp); Map<String, Object> rc = ((BindingProvider) client).getRequestContext(); rc.put(WSSecurityContext.CREDENTIAL_PROVIDER_LIST, credProviders); ... I am able to generate my Proxy classes using Metro however I can not figure out how to configure it to send the UsernameToken. I have attempted several different examples from the web which have not worked. Any help would be appreciated.

    I'm using the RC of visual Studio 2010. Writing a .net 3.5 application. When I launch the app, the listview control only shows in LargeIcon view. This is not the view I want. I've set the View property in the designer with no success. I've even tried to explicitly set the view during runtime lvAvailableItems.View = View.Tile; Has anyone else had this issue, and if so what was your workaround.
