  • Can someone help me with this StructureMap error i'm getting?

    - by Pure.Krome
    Hi folks, I'm trying to wire up a simple ASP.NET MVC2 controller class to my own LoggingService. Code compiles fine, but I get the following runtime error :- {"StructureMap Exception Code: 202 No Default Instance defined for PluginFamily System.Type, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"} what the? mscorlib ???? Here's some sample code of my wiring up .. protected void Application_Start() { MvcHandler.DisableMvcResponseHeader = true; BootstrapStructureMap(); ControllerBuilder.Current.SetControllerFactory( new StructureMapControllerFactory()); RegisterRoutes(RouteTable.Routes); } private static void BootstrapStructureMap() { ObjectFactory.Initialize(x => x.For<ILoggingService>().Use<Log4NetLoggingService>()); } and finally the controller, simplified for this question ... public class SearchController : Controller { private readonly ILoggingService _log { get; set; } public SearchController(ILoggingService loggingService) : base(loggingService) { // Error checking removed for brevity. _log = loggingService; _log.Tag = "SearchController"; } ... } and the structuremap factory (main method), also way simplified for this question... protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { IController result = null; if (controllerType != null) { try { result = ObjectFactory.GetInstance(controllerType) as Controller; } catch (Exception exception) { if (exception is StructureMapException) { Debug.WriteLine(ObjectFactory.WhatDoIHave()); } } } } hmm. I just don't get it. StructureMap version 2.6.1.0 ASP.NET MVC 2. Any ideas?

  • Can't make my WCF extension work

    - by Sergio Romero
    I have a WCF solution that consists of the following class libraries: Exercise.Services: Contains the implementation classes for the services. Exercise.ServiceProxy: Contains the classes that are instantiated in the client. Exercise.HttpHost: Contains the services (*.svc files). I'm calling the service from a console application and the "first version" works really well so I took the next step which is to create a custom ServiceHostFactory, ServiceHost, and InstanceProvider so I can use constructor injection in my services as it is explained in this article. These classes are implemented in yet another class library: 4. Exercise.StructureMapWcfExtension Now even though I've modified my service this: <%@ ServiceHost Language="C#" Debug="true" Factory="Exercise.StructureMapWcfExtension.StructureMapServiceHostFactory" Service="Exercise.Services.PurchaseOrderService" %> I always get the following exception: System.ServiceModel.CommunicationException Security negotiation failed because the remote party did not send back a reply in a timely manner. This may be because the underlying transport connection was aborted. It fails in this line of code: public class PurchaseOrderProxy : ClientBase<IPurchaseOrderService>, IPurchaseOrderService { public PurchaseOrderResponse CreatePurchaseOrder(PurchaseOrderRequest purchaseOrderRequest) { return base.Channel.CreatePurchaseOrder(purchaseOrderRequest); //Fails here } } But that is not all, I added a trace to the web.config file and this is the error that appears in the log file: System.InvalidOperationException The service type provided could not be loaded as a service because it does not have a default (parameter-less) constructor. To fix the problem, add a default constructor to the type, or pass an instance of the type to the host. So this means that my ServiceHostFactory is never being hit, I even set a breakpoint in both its constructor and its method and they never get hit. I've added a reference of the StructureMapWcfExtension library to all the other ones (even the console client), one by one to no avail. I also tried to use the option in the host's web.config file to configure the factory like so: <serviceHostingEnvironment> <serviceActivations> <add service="Exercise.Services.PurchaseOrderService" relativeAddress="PurchaseOrderService.svc" factory="Exercise.StructureMapWcfExtension.StructureMapServiceHostFactory"/> </serviceActivations> </serviceHostingEnvironment> That didn't work either. Please I need help in getting this to work so I can incorporate it to our project. Thank you. UPDATE: Here's the service host factory's code: namespace Exercise.StructureMapWcfExtension { public class StructureMapServiceHostFactory : ServiceHostFactory { private readonly Container Container; public StructureMapServiceHostFactory() { Container = new Container(); new ContainerConfigurer().Configure(Container); } protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { return new StructureMapServiceHost(Container, serviceType, baseAddresses); } } public class ContainerConfigurer { public void Configure(Container container) { container.Configure(r => r.For<IPurchaseOrderFacade>().Use<PurchaseOrderFacade>()); } } }

  • Passing constructor arguments when using StructureMap

    - by Mosh
    Hello, I'm using StructureMap for my DI. Imagine I have a class that takes 1 argument like: public class ProductProvider : IProductProvider { public ProductProvider(string connectionString) { .... } } I need to specify the "connectionString at run-time when I get an instance of IProductProvider. I have configured StructureMap as follows: ForRequestedType<IProductProvider>.TheDefault.Is.OfConcreteType<ProductProvider>(). WithCtorArgument("connectionString"); However, I don't want to call EqualTo("something...") method here as I need some facility to dynamically specify this value at run-time. My question is: how can I get an instance of IProductProvider by using ObjectFactory? Currently, I have something like: ObjectFactory.GetInstance<IProductProvider>(); But as you know, this doesn't work... Any advice would be greatly appreciated.

  • Response.Redirect in a COM+ Object Called from Classic ASP Page

    - by ajdams
    Basically we moved from IIS 5 to IIS 7 and I am trying to update some of our old COM objects to .NET by rewriting them in C#. What I am have so far is a Classic ASP page calling the COM+ object and then I am trying to do a simple redirect within the COM+ object (this is just for testing purposes, it's not what the object will do eventually). My problem/question is, why does the redirect call not work properly? Am I doing something wrong or can you not redirect within a COM+ object? All that happens is a blank white page comes up and if I check the IIS logs, I see no errors. Here is my code so far: In Classic ASP (the call to COM+) Set oBankReg = CreateObject("BVSRegistration.SignIn") oBankReg.GetBankId(bankid) Code in C# COM object: using System; using System.Web; using System.Text; using System.EnterpriseServices; using System.Collections.Generic; using System.Runtime.InteropServices; [assembly: ApplicationName("BVSRegistration")] [assembly: Description("COM+ upgrade of the BVSRegistration VB6 SignIn.cls.")] [assembly: ApplicationActivation(ActivationOption.Server)] [assembly: ApplicationAccessControl(false, AccessChecksLevel = AccessChecksLevelOption.ApplicationComponent)] namespace BVSRegistration { public class SignIn : ServicedComponent { public void GetBankId(string bankid) { HttpContext.Current.Response.Redirect("http://www.google.com"); } } } Any ideas? Thanks

  • .Net: Prevent an object from being paged out (VirtualLock equivalent)

    - by Gene
    How would one go about keep an object in memory such that it won't be paged out by the OS in .Net? i.e. Something similar to VirtualLock, but operating on an object, such that if compacting occurs and the object is moved it still would not be paged out, etc.. (I suppose one could pin the object's, determine what pages it belongs to, and then VirtualLock those pages, but that seems non-desireable for many reasons.) If possible, could you point me to a reference or working sample? (C# ideally) Many thanks in advance!

  • Using ninject/autofac for a given scenario

    - by sandesh247
    I have some providers, say - <Providers> <Provider Type="Providers.IM" Name="Im"/> <Provider Type="Providers.Web" Name="Web"/> ... </Provider> Each of these providers can give me a session : <Sessions> <Session Name="GoogleIM" Provider="Im" URL="..." /> <Session Name="YahooIM" Provider="Im" URL="..." /> <Session Name="YahooWeb" Provider="Web" URL="..." /> ... </Session> Currently, I instantiate "named" sessions by looking at the provider, instantiating the type, and injecting the URL (manually). I could use a session factory, which would probably have to understand the url and return a proper session. Is there a way to handle this more elegantly/simply with ninject/autofac?

    I have standard maven project in netbeans (netbeans' enterprise application), that have 1 war, 1 ejb and 1 ear modules. I want to inject with @Inject my @Stateless from ejb to war (REST class) using its interface. I have added some beans.xml files in correct folders in project, but im still getting this: Error occurred during deployment: Exception while loading the app : WELD-001409 Ambiguous dependencies for type [LogicBean] with qualifiers [@Default] at injection point [[field] @Inject private pl.edu.amu.wmi.kino.rk.rest.ReportRest.bean].

  • Building Java projects with circular imports in Eclipse

    - by Buggieboy
    I have a legacy Java (not my native language) app that I'm trying to build in Eclipse Galileo. As it's not my own, I can't speak to the quality of the design, but I am coming across a number of instances where I'll have something like this: In a project called, say, "lib_a", I'll have a file containing this: import com.acme.lib_b.onething; Project "lib_b" on the other hand, will contain: import com.acme.lib_a.anotherthing; Of course, the problem is that one project can't be built because the errors prevent me from creating a .jar file that can be added as an external archive to the other project, and vice versa. It seems to me that this must be a fairly common occurence in building Java applications. Rewriting it from scratch is not an option here, so I'd like to know "what other folks do."

  • Castle Windsor: Inject NameValueCollection vs. Dictionary

    - by Aren B
    I've already done many configs where dictionaries are passed into services in the <parameters> block. But what I find myself needing right now is to build a NameValueCollection (allowing multiple entries with the same key) or a Collection of KeyValuePair objects. The reason for this is im not using this dictionary to look up b when given a, im basically using it to pass in a Tuple (pair) of (a,b) to be used later in code. Im kind of new to castle windor and I was wondering how i would go about making a List of KeyValuePair's injected, or a NameValueCollection injected.

  • Autofac in web applications, where should I store the container for easy access

    - by michielvoo
    I'm still pretty new to using Autofac and one thing I miss in the documentation and examples is how to make it easy to get to the configured container from different places in a web application. I know I can use the Autofac controller factory to automatically resolve constructor injected dependencies for controllers, but how about the other stuff you might need to resolve that is not injected yet. Is there an obvious pattern I am not aware of for this? Thank you!

  • Structuremap Stackoverflow Exception

    - by Jason Young
    I keep getting a stackoverflow exception when I call "GetInstance" (the last line). All, yes ALL of my types implement ITracker. MultiTracker has a constructor with a single parameter, which is an array of ITracker's. It seems like StructureMap is ignoring the fact that I told it that MultiTracker is the default class I want when requesting the type ITracker. I just can't get it to work. Any thoughts? Container = new Container(x => { //Multitracker takes ITracker[] in its constructor x.ForRequestedType<MultiTracker>().TheDefault.Is.OfConcreteType<MultiTracker>().TheArrayOf<ITracker>().Contains(z => { z.OfConcreteType<ConcreteType1>(); //ConcreteType1 : ITracker z.OfConcreteType<ConcreteType2>(); //ConcreteType2 : ITracker }); x.ForRequestedType<ITracker>().TheDefault.Is.OfConcreteType<MultiTracker>(); }); //Run a test - this explodes Container.GetInstance<ITracker>();

  • Which single IoC/DI container would you recommend using and why?

    - by Rob G
    I'm asking this question because it's a good way to gauge how the community at large feels about the various containers/frameworks and why. Also, whilst my expertise may lie in .Net development, I am very interested in which frameworks are popular (and why) in other languages. If I feel the need to start digging into Java for instance, then I'd like to hit the ground running with good (comfortable) knowledge that I'm starting in the right direction. Does Ruby even need one with all its magnificent dynamicism? I have my own opinions on the .Net front, and will probably add my own personal favourite in an answer below, but I'm interested in all languages and opinions here. With all that in mind, could you please state only one IoC/DI framework that you use and recommend with the language of choice (Java/Ruby/.Net/Smalltalk etc.) and your reasoning for your choice, and if someone has already answered your particular flavour, then you can just vote it up and add comments to it so that anyone looking for advice in future and see which frameworks are more than likely to work for them once they read your reasoning. I'm hoping that over time, the best ones will bubble up to the top. I realise that this question doesn't have only one correct answer, so I won't be choosing one - the community will decide which framework gets the most votes and why. Of course, if you really feel strongly opposed to a particular brand, you could take the reputation hit and vote it down too, and this question can serve as a true wiki-style entry for research into this field. Remember, only one IoC per answer you write please - if you feel the need to promote two frameworks, then write two answers with your reasoning inside for each choice - then others in the community can agree or disagree with you.

  • Unit test complex classes with many private methods

    - by Simon G
    Hi, I've got a class with one public method and many private methods which are run depending on what parameter are passed to the public method so my code looks something like: public class SomeComplexClass { IRepository _repository; public SomeComplexClass() this(new Repository()) { } public SomeComplexClass(IRepository repository) { _repository = repository; } public List<int> SomeComplexCalcualation(int option) { var list = new List<int>(); if (option == 1) list = CalculateOptionOne(); else if (option == 2) list = CalculateOptionTwo(); else if (option == 3) list = CalculateOptionThree(); else if (option == 4) list = CalculateOptionFour(); else if (option == 5) list = CalculateOptionFive(); return list; } private List<int> CalculateOptionOne() { // Some calculation } private List<int> CalculateOptionTwo() { // Some calculation } private List<int> CalculateOptionThree() { // Some calculation } private List<int> CalculateOptionFour() { // Some calculation } private List<int> CalculateOptionFive() { // Some calculation } } I've thought of a few ways to test this class but all of them seem overly complex or expose the methods more than I would like. The options so far are: Set all the private methods to internal and use [assembly: InternalsVisibleTo()] Separate out all the private methods into a separate class and create an interface. Make all the methods virtual and in my tests create a new class that inherits from this class and override the methods. Are there any other options for testing the above class that would be better that what I've listed? If you would pick one of the ones I've listed can you explain why? Thanks

  • NHibernate Session DI from StructureMap in components

    - by Corey Coogan
    I know this is somewhat of a dead horse, but I'm not finding a satisfactory answer. First let me say, I am NOT dealing with a web app, otherwise managing NH Session is quite simple. I have a bunch of enterprise components. Those components have their own service layer that will act on multiple repositories. For example: Claim Component Claim Processing Service Claim Repository Billing Component Billing Service Billing REpository Policy Component PolicyLockService Policy Repository Now I may have a console, or windows application that needs to coordinate an operation that involves each of the services. I want to write the services to be injected with (DI) their required repositories. The Repositories should have an ISession, or similar, injected into them so that I can have this operation performed under one ISession/ITransaction. I'm aware of the Unit Of Work pattern and the many samples out there, but none of them showed DI. I'm also leery of [ThreadStatic] because this stuff can also be used from WCF and I have found enough posts describing how to do that. I've read about Business Conversations, but need something simple that each windows/console app can easily bootstrap since we have alot of these apps and some pretty inexperienced developers. So how can I configure StructureMap to inject the same ISession into each of the dependent repositories from an application? Here's a totally contrived and totally made up example without using SM (for clarification only - please don't spend energy critisizing): ConsoleApplication Main { using(ISession session = GetSession()) using(ITransaction trans = session.BeginTransaction()) { var policyRepo = new PolicyRepo(session); var policyService = new PolicyService(policyRepo); var billingRepo = new BillingRepo(session) var billingService = new BillingService(billingRepo); var claimRepo = new ClaimsRepo(session); var claimService = new ClaimService(claimRepo, policyService, billingService); claimService.FileCLaim(); trans.Commit(); } }

  • [StructureMap] Xml configuration or Configuration through code?

    - by Amith George
    I personally like the option to configure StructureMap from C# code. From what I understand, one of the advantages of DI, is that we can easily swap in a new concrete instance. But, if the configuration is defined in code, then the concrete instances are hardcoded in the dll. So, practically, its as good as having hard coded the dependencies, right? I know, during testing it makes life easier... My point is, wouldnt it be better to use xml configuration instead? you want to plugin a new concrete instance? simply have your installer overwrite the structuremap.config file with the new one. So, what is the preferred way to configure StructureMap? Extra: Am forced to use C# configuration for the time being because I dont know how to pass the connection string to instance. I can write the connectionstring in the config file, but i would like to reuse the connectionstring defined in app.config.

  • ComDlg32.ocx Error: Object doesn't support this property or method

    - by abhilashca
    I'm developing an html editor using ComDlg32.ocx (Commom Dialog Control), using HTML and VBScript. My exact requirement was to prompt Open/Save/Color/Print/Font dialog boxes.Ive written code for prompting Save file dialog box. Also I've added a license file using LPK Tool onto my webpage. My html-source looks like: <body> <!-- lpk file --> <object classid="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"> <param name="LPKPath" value="License/comdlg.lpk" /> </object> <!-- Microsoft Common Dialog Control --> <object classid="CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB" codebase="http://activex.microsoft.com/controls/vb6/COMDLG32.CAB" id="objComDlg"></object> </body> Now, here comes my error. Whenever I try to call the vbscript for prompting the Save File dialog box, Im getting an error as : Object doesn't support this property or method: 'objComDlg.Filter' If I comment out the objComDlg.Filter then the error move on to objComDlg.DialogTitle and thus it goes on. And my VBScript look like: FILE_FORMATS = "Rich Text Format (*.rtf)|*.rtf|Microsoft Word (*.doc)|*.doc|ANSI Text Document (*.txt)|*.txt" objComDlg.Filter = FILE_FORMATS <--- Error shows here objComDlg.DialogTitle = "Save As " objComDlg.Flags = cdlOFNFileMustExist Or cdlOFNHideReadOnly objComDlg.CancelError = True objComDlg.ShowSave Does anyone have an idea why this is happening? Is there any proper documentation for using this particular ActiveX control? My current development is in stand-still due to this error. Any help will be appreciated. Looking forward for your response. BTW, I'm using Windows XP SP3 and IE8 for my development. Thanks.

  • Getting COM object to run in Vista

    - by rainslg
    We expose an interface to our simulation software using a COM/ActiveX object. This worked just fine in XP, but in Vista, we get "Error 429: ActiveX can't create object" when a VB client executes CreateObject(). The COM object has been registered by hand so that the Vista Registry is identical to XP's Registry. I run the VB interface from a DOS window that I started using "Run As Administrator". The client is correctly accessing and reading the Registry as I walk through using the debugger in VB, so it's apparently not a security setting, as near as I can tell. I have also loaded the files into VS2005 (the object was originally created in VS6) and rebuilt them to get a later ATL version, but that hasn't helped - we still get the 429 error. Is this a symptom of UAC problems, or should I be looking for something deeper?

  • IoC from start to finish

    - by Dave
    I'm quite sure that IoC is the way to go for my application. There are a ton of articles and even questions here on SO that discuss the different containers. I've read several blogs today with partial examples. I am personally leaning towards starting with the CommonServiceLocator and Unity as two way to solve the same problem -- I just need a bunch of assemblies to get data from a database, which I assume is what needs to be injected everywhere. I've yet to find any sites that really take a problem from beginning to end, with concrete code examples. For example, I've yet to find one that discusses an IServiceLocator and how to actually register it (or do whatever is required to make it known). What are your favorite posts / articles / SO questions that can take a noob from start to finish with the implementation?
