  • Inherited properties aren't bound during databinding

    - by Josh
    I have two interfaces, IAuditable and ITransaction. public interface IAuditable{ DateTime CreatedOn { get; } string CreatedBy { get; } } public interface ITransaction : IAuditable { double Amount{ get; } } And a class that implements ITransaction, call Transaction. public class Transaction : ITransaction{ public DateTime CreatedOn { get { return DateTime.Now; } } public string CreatedBy { get { return "aspnet"; } } public doubl Amount { get { return 0; } } } When I bind a list of ITransactions to a datagrid and use auto create columns, only the Amount gets bound. The CreatedBy and CreatedOn are not seen. Is there a way I can get these values visible during databinding?

  • DependencyProperty binding not happening on initial load

    - by Ari Roth
    I'm trying to do something simple -- make a DependencyProperty and then bind to it. However, the getter doesn't appear to fire when I start up the app. (I'm guessing the solution will make me smack my head and go "Doh!", but still. :) ) Any ideas? Code-behind code: public static readonly DependencyProperty PriorityProperty = DependencyProperty.Register("Priority", typeof (Priority), typeof (PriorityControl), null); public Priority Priority { get { return (Priority)GetValue(PriorityProperty); } set { SetValue(PriorityProperty, value); } } Control XAML: <ListBox Background="Transparent" BorderThickness="0" ItemsSource="{Binding Path=Priorities}" Name="PriorityList" SelectedItem="{Binding Path=Priority, Mode=TwoWay}"> <ListBox.ItemTemplate> <DataTemplate> <Grid Height="16" Width="16"> <Border BorderBrush="Black" BorderThickness="2" CornerRadius="3" Visibility="{Binding RelativeSource= {RelativeSource Mode=FindAncestor, AncestorType=ListBoxItem}, Path=IsSelected, Converter={StaticResource boolToVisibilityConverter}}" /> <Border CornerRadius="3" Height="12" Width="12"> <Border.Background> <SolidColorBrush Color="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListBoxItem}, Path=Content, Converter={StaticResource priorityToColorConverter}}" /> </Border.Background> </Border> </Grid> </DataTemplate> </ListBox.ItemTemplate> <ListBox.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ListBox.ItemsPanel> </ListBox> Binding statement: <UI:PriorityControl Grid.Column="8" Priority="{Binding Path=Priority}" VerticalAlignment="Center"/> Some other notes: Binding is in a UserControl UserControl contains the PriorityControl PriorityControl contains the DependencyProperty I've checked that the data the UserControl is getting the appropriate data -- every other binding works. If I change the selection on the PriorityControl via the mouse, everything fires as appropriate. It's just that initial setting of the value that isn't working. Priority is an enum.

  • Is is possible to programmatically change the resourceProviderFactoryType?

    - by Robert Massa
    I have a custom implementation of IResourceProvider and ResourceProviderFactory. Now the default way of making sure ASP.NET uses these custom types is to use the web.config and specify the factory like so: <globalization resourceProviderFactoryType="Product.Globalization.TranslationResourceProviderFactory" /> This works perfectly, except that in my resource provider I need database access. I want to use my IoC-container(Ninject) to inject the repositories needed to access this data into the CustomResourceProvider. But how am I going to do this? I have no control over the instantiation of the factory, so the factory can't get a reference to my IoC. Is there any way to register a custom provider programmatically, in for example the Global.asax?

  • To see javascript object properties and functions with intellisense in VS.NET 2008

    - by uzay95
    I am creating classes in external files.And adding them with <script src='../js/clsClassName.js' type='text/javascript'></script> tags. When i created an object from this class I can't access its props, and functions with intellisense. Is there any way to achieve this? Sample javascript class: // clsClassName.js function ClassName(_param1, _param2, _param3) { this.Prop1 = _param1; this.Prop1 = _param2; this.Prop3 = _param3; } ClassName.prototype.f_Add = function(fBefore, fSuccess, fComplete, fError) { } ClassName.prototype.f_Delete = function(fBefore, fSuccess, fComplete, fError) { } Any help would be greatly appreciated...

  • Extension Method for copying properties form object to another, with first attempt

    - by James
    Hi All, Im trying to write an extension method that I can use to copy values from one object property to another object of a different type, as long as the property names and types match exactly. This is what I have: public static T CopyFrom<T>(this T toObject, object fromObject) { var fromObjectType = fromObject.GetType(); var fromProperties = fromObjectType.GetProperties(); foreach (PropertyInfo toProperty in toObject.GetType().GetProperties()) { PropertyInfo fromProperty = fromObjectType.GetProperty(toProperty.Name); if (fromProperty != null) // match found { // check types var fromType = fromProperty.PropertyType.UnderlyingSystemType; var toType = toProperty.PropertyType.UnderlyingSystemType; if (toType.IsAssignableFrom(fromType)) { toProperty.SetValue(toObject, fromProperty.GetValue(fromObject, null), null); } } } return toObject; } This is working great for non boxed types, but Nullable<T> returns false when I call toType.IsAssignableFrom(fromType) because its type is Nullable<T> and is not the underlying type T. I read here that GetType() should unbox the Nullable<T> so it returns T but if I call that on PropertyInfo.PropertyType I get ReflectedMemberInfo and not the type T im looking for. I think im missing something obvious here, so I thought I would throw it open to SO to get some advice. Anyone have any ideas? Thanks, Jamee

  • Using Factory to get Injected objects

    - by ryudice
    Is it good practice to have a Factory method to retrieve injected objects or is it OK to just use the factory method from the DI framework? I'm using structure map, should I just use ObjectFactory.GetInstance();, or should I create factory class and inside this class call ObjectFactory.GetInstance();? because if I call ObjectFactory.GetInstance(); in my classes I would be creating coupling to the DI framework? sorry if I'm being ignorant, I'm new to this concepts. Thanks!

  • Help getting started with MEF

    - by SteveCl
    Hi, I was reading somewhere that with MEF I can simply drop a dll into a directory and my application (with some MEF magic) will be able to read it and execute the code in it? Hopefully only classes that implement an interface that I define?? Can someone help me to get going, with some links maybe for my problem. I've looked through some of the docs, but nothing seems to be what I'm after and its tricky when I don't know exactly what to search on... Thx S

  • Spring 2.5 managed servlets: howto?

    - by EugeneP
    Correct me if anything is wrong. As I understand, all Spring functionality, namely DI works when beans are got thru Spring Context, ie getBean() method. Otherwise, none can work, even if my method is marked @Transactional and I will create the owning class with a new operator, no transaction management will be provided. I use Tomcat 6 as a servlet container. So, my question is: how to make Servlet methods managed by Spring framework. The issue here is that I use a framework, and its servlets extend the functionality of basic java Servlets, so they have more methods. Still, web.xml is present in an app as usual. The thing is that I do not control the servlets creation flow, I can only override a few methods of each servlet, the flow is basically written down in some xml file, but I control this process using a graphical gui. So, basically, I only add some code to a few methods of each Servlet. How to make those methods managed by Spring framework? The basic thing I need to do is making these methods transactional (@Transactional).

  • Can I inject a SessionBean into a JEE AroundInvoke-Interceptor?

    - by Michael Locher
    I have an EAR with modules: foo-api.jar foo-impl.jar interceptor.jar In foo-api there is: @Local FooService // (interface of a local stateless session bean) In foo-impl there is: @Stateless FooServiceImpl implements FooService //(implementation of the foo service) In interceptor.jar I want public class BazInterceptor { @EJB private FooService foo; @AroundInvoke public Object intercept( final InvocationContext i) throws Exception { // do someting with foo service return i.proceed(); } The question is: Will a Java EE 5 compliant application server (e.g. JBoss 5) inject into the interceptor? If no, what is good strategy for accessing the session bean? To consider: Deployment ordering / race conditions

  • 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.

  • 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?

  • VB Classes Best Practice - give all properties values?

    - by Becky Franklin
    Sorry if this is a bit random, but is it good practice to give all fields of a class a value when the class is instanciated? I'm just wondering if its better practice to have a constuctor that takes no parameters and gives all the fields default values, or whether fields that have values should be assigned and others left alone until required? I hope that makes sense, Becky

  • Rtti accessing fields and properties in complex data structures

    - by Coco
    As already discussed in Rtti data manipulation and consistency in Delphi 2010 a consistency between the original data and rtti values can be reached by accessing members by using a pair of TRttiField and an instance pointer. This would be very easy in case of a simple class with only basic member types (like e.g. integers or strings). But what if we have structured field types? Here is an example: TIntArray = array [0..1] of Integer; TPointArray = array [0..1] of Point; TExampleClass = class private FPoint : TPoint; FAnotherClass : TAnotherClass; FIntArray : TIntArray; FPointArray : TPointArray; public property Point : TPoint read FPoint write FPoint; //.... and so on end; For an easy access of Members I want to buil a tree of member-nodes, which provides an interface for getting and setting values, getting attributes, serializing/deserializing values and so on. TMemberNode = class private FMember : TRttiMember; FParent : TMemberNode; FInstance : Pointer; public property Value : TValue read GetValue write SetValue; //uses FInstance end; So the most important thing is getting/setting the values, which is done - as stated before - by using the GetValue and SetValue functions of TRttiField. So what is the Instance for FPoint members? Let's say Parent is the Node for TExample class, where the instance is known and the member is a field, then Instance would be: FInstance := Pointer (Integer (Parent.Instance) + TRttiField (FMember).Offset); But what if I want to know the Instance for a record property? There is no offset in this case. So is there a better solution to get a pointer to the data? For the FAnotherClass member, the Instance would be: FInstance := Parent.Value.AsObject; So far the solution works, and data manipulation can be done by using rtti or the original types, without losing information. But things get harder, when working with arrays. Especially the second array of Points. How can I get the instance for the members of points in this case?

  • 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?

All my node elements are drawn on top of each other in the same position. Any suggestions on how to accomplish this?

  • Component properties working at designtime but not runtime

    - by delphi-rulez-2010
    I am creating a component that uses a collection and collection items of panels. I can't seem to get the colors to work at runtime, but yet they seem to work just fine at design time. You can download the component source code here: http://www.shaneholmes.net/pasfiles/ There is a Consoles (Tcollection) property, status colors property, and a Edit mode property Each console (TCollectionItem) has a status property when changed, the consoles property is changed based on the components StatusColors property. When the components EditMode property is set to true, you can move the panels around at runtime. Question: Why does the colors only work at designtime and not runtime. thanks

  • 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.

  • 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."

  • 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>();
