  • WCF <operation>Async methods not generated in proxy interface

    - by Charlie
    I want to use the Asnyc methods rather than the Begin on my WCF service client proxy because I'm updating WPF controls and need to make sure they're being updated from the UI thread. I could use the Dispatcher class to queue items for the UI thread but that's not what I'm asking about.. I've configured the service reference to generate the asynchronous operations, but it only generates the methods in proxy's implementation, not it's interface. The interface only contains syncronous and Begin methods. Why aren't these methods generated in the interface and is there a way to do this, or do I have to create a derived interface to manually add them?

  • Controller Index methods with different signatures

    - by Narsil

  • Capistrano deploying to different servers with different authentication methods

    - by marimaf
    I need to deploy to 2 different server and these 2 servers have different authentication methods (one is my university's server and the other is an amazon web server AWS) I already have running capistrano for my university's server, but I don't know how to add the deployment to AWS since for this one I need to add ssh options for example to user the .pem file, like this: ssh_options[:keys] = [File.join(ENV["HOME"], ".ssh", "test.pem")] ssh_options[:forward_agent] = true I have browsed starckoverflow and no post mention about how to deal with different authentication methods this and this I found a post that talks about 2 different keys, but this one refers to a server and a git, both usings different pem files. This is not the case. I got to this tutorial, but couldn't find what I need. I don't know if this is relevant for what I am asking: I am working on a rails app with ruby 1.9.2p290 and rails 3.0.10 and I am using an svn repository Please any help os welcome. Thanks a lot

  • Confused about this factory, as it doesn't look like an Abstract Factory nor Factory Method

    - by Pin
    I'm looking into Guice and I've been reading its documentation recently. Reading the motivation section I don't understand the factories part, why they name it that way. To me that factory is just a wrapper for the implementing class they want it to return after calling getInstance(). public class CreditCardProcessorFactory { private static CreditCardProcessor instance; public static void setInstance(CreditCardProcessor creditCardProcessor) { instance = creditCardProcessor; } public static CreditCardProcessor getInstance() { if (instance == null) { throw new IllegalStateException("CreditCardProcessorFactory not initialized. " + "Did you forget to call CreditCardProcessor.setInstance() ?"); } return instance; } } Why do they call it factory as well if it is neither an abstract factory nor a factory method? Or am I missing something? Thanks.

  • Using SoapExtensionAttributes on client side with async web methods

    - by Maxim Polishchuk
    Hey, I have a simple question. I implemented custom soap extension and registered it into client application configuration file. It works fine. (I would like to implement progress bar functionality like http://msdn.microsoft.com/en-us/library/aa480520.aspx) But I don't like some thing - custom soap extension is invoked by every call of my web service. In order to fix this situation (call WS just by required methods) I implemented custom SoapExtensionAttribute like below: [AttributeUsage(AttributeTargets.Method)] public class CustomSoapExtensionAttribute : SoapExtensionAttribute { public override int Priority { get; set; } public CustomSoapExtensionAttribute() : this (1) { } public CustomSoapExtensionAttribute(int priority) { Priority = priority; } public override Type ExtensionType { get { return typeof(CustomSoapExtension); } } } I added this attribute to required methods of web service proxy classes (and removed registration into client configuration file). My soap extension doesn't invoke when required web methods are calling. Can someone help me to solve this problem or select any other solution? Anotherone, I don't know it is important or not - my required methods are async web methods. Best regards, Maxim

  • Factory, Abstract Factory and Factory Method

    - by skydoor
    Hi, I am really confused about these three terms. My understanding is that: in the Factory pattern, there is no concrete factory. The factory builds the new objects according to the parameters. in Abstract Factory pattern, there are multiple concrete factories. The client has to create different concrete factories explicitly. Is that right? What are the other differences? Furthermore, what is the Factory Method pattern? Is it same as the Factory pattern?

  • JavaScript private methods

    - by Wayne Kao
    To make a JavaScript class with a public method I'd do something like: function Restaurant() { } Restaurant.prototype.buy_food = function() { // something here } Restaurant.prototype.use_restroom = function() { // something here } That way users of my class can: var restaurant = new Restaurant(); restaurant.buy_food(); restaurant.use_restroom(); How do I create a private method that my public buy_food and use_restroom methods can call but that users of the class can't call externally. In other words, I want my method implementation to be able to do: Restaurant.prototype.use_restroom = function() { this.private_stuff(); } But this shouldn't work: var r = new Restaurant(); r.private_stuff(); How do I define private_stuff as a private method so both of those hold true? I've read Doug Crockford's writeup a few times but it doesn't seem like "private" methods can be called by public methods and "privileged" methods can be called externally.

  • eclipse add unimplemented methods including javadoc

    - by dcp
    When implementing an interface in eclipse, it has a really nice feature that lets you "add unimplemented methods", and it will generate the method stubs for the interface methods. However, it does not bring along the method documentation from the interface methods, and I was wondering if there was a way to get eclipse to do that.

  • How to restrict HTTP Methods

    - by hemalshah
    I want to restrict HTTP methods to those required by the MOSS07 application(s) using IIS6. I am not able to find a solution after googling. Can any one help. Update this is what was written in the document IIS6 should be used to restrict HTTP methods to those required by the MOSS07 application(s). I also searched some books and saw something curious in O'Reilly's Sharepoint 2007 by James Pyles and others. There is no real suppported way to use HTTP POST and HTTP GET because of the web.config settings and the static definition of the WSDL. In the web.config <protocols> <remove name="HttpGet"> <remove name="HttpPost"> <remove name="HttpPostLocalHost"> <add name="Documentation"> </protocols> If we do this in the Web.Config file, would it solve the problem?

  • Class Methods Inheritence

    - by Roman A. Taycher
    I was told that static methods in java didn't have Inheritance but when I try the following test package test1; public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { TB.ttt(); TB.ttt2(); } } package test1; public class TA { static public Boolean ttt() { System.out.println("TestInheritenceA"); return true; } static public String test ="ClassA"; } package test1; public class TB extends TA{ static public void ttt2(){ System.out.println(test); } } it printed : TestInheritenceA ClassA so do java static methods (and fields have) inheritance (if you try to call a class method does it go down the inheritance chai looking for class methods). Was this ever not the case,are there any inheritance OO languages that are messed up like that for class methods?

  • Drawbacks with using Class Methods in Objective C.

    - by RickiG
    Hi I was wondering if there are any memory/performance drawbacks, or just drawbacks in general, with using Class Methods like: + (void)myClassMethod:(NSString *)param { // much to be done... } or + (NSArray*)myClassMethod:(NSString *)param { // much to be done... return [NSArray autorelease]; } It is convenient placing a lot of functionality in Class Methods, especially in an environment where I have to deal with memory management(iPhone), but there is usually a catch when something is convenient? An example could be a thought up Web Service that consisted of a lot of classes with very simple functionality. i.e. TomorrowsXMLResults; TodaysXMLResults; YesterdaysXMLResults; MondaysXMLResults; TuesdaysXMLResults; . . . n I collect a ton of these in my Web Service Class and just instantiate the web service class and let methods on this class call Class Methods on the 'Results' Classes. The classes are simple but they handle large amount of Xml, instantiate lots of objects etc. I guess I am asking if Class Methods lives or are treated different on the stack and in memory than messages to instantiated objects? Or are they just instantiated and pulled down again behind the scenes and thus, just a way of saving a few lines of code?

  • Layered Architecture and Static Methods

    - by BigBoss
    I need suggestion for three layered architecture I am planning to implement. Scenario Am Working in ASP.NET c# 3.5 Environment. DLHelper: Methods to get data from database. DAL : Contains Methods which collects data from database with help of DLHelper classes. Most of the methods in this layer are not referencing any page level object, hence can be declared static. BL : Same as DAL Layer, most of the methods are not referencing any page other page level object, hence can be declared static. UI Layer: As per above scenario UI Layer call to BL Layer is like BLClass.Method - DALClass.Method Question I would like to know is this standardise way to do it. As per discussion with my co-worker, we should have corresponding object of BL/DAL layer. But am still looking for more convencing answer.

  • multiple classes with same methods - best pattern

    - by Tony
    I have a few classes in my current project where validation of Email/Website addresses is necessary. The methods to do that are all the same. I wondered what's the best way to implement this, so I don't need to have these methods copy pasted everywhere? The classes themselves are not necessarily related, they only have those validation methods in common.

  • abstract class in C++

    - by Alexander
    I have a derived derived class from an abstract class. The code is below. I have a FishTank class which is derived from an Aquarium and Aquarium is derived from item. My question is that should I put the definition of virtual int minWidth() const = 0; in aquarium again or is the code below sufficient? class Item{ public: virtual int minWidth() const = 0; }; class Aquarium{ public: virtual int calWidth() = 0; // Pure virtual function. }; class FishTank : public Aquarium{ public: FishTank(int base1, int base2, int height); ~FishTank(); int calWidth(); int minWidth(); };

  • Invoking web service methods from code-behind

    - by Peter Wone
    The application on which I am working has a web service exposing various methods. Most of these methods use WebOperationContext.Current to set headers up to prevent cacheing. This works fine when the service methods are consumed in AJAX via the generated proxy, but when I attempt to do the same thing from code-behind, WebOperationContext.Current is null. Can anyone tell me how to confer appropriate call context on the method invocation?

  • Method For Making Methods: Easy Ruby Metaprogramming

    I have a bunch of methods like this in view helper def background "#e9eaec" end def footer_link_color "#836448" end I'd like these methods exposed to the view, but I'd prefer the helper to be a bit more concise. What's the best way to turn a hash, say, into methods (or something else)?

  • Why methods in C# are not automatically virtual?

    - by Alon
    It would be much more less work to define which methods are NOT overideable instead of which are overideable because (at least for me), when you're designing a class, you don't care if its heirs will override your methods or not... So, why methods in C# are not automatically virtual? What is the common sense in this?

  • How to apply Abstract Factory Pattern ???

    - by Amit
    I am new to Design Pattern and I have a scenario here... and not sure as how to implement the pattern ... We have multiple vendors Philips, Onida... Each vendor (philips, onida...) may have different type of product i.e. Plasma or Normal TV I want specific product of each vendor using Abstract Factory Pattern... Thanks in advance for any help... My implementation so far... public enum TvType { Samsung = 0,LG = 1,Philips = 2, Sony = 3 } public enum Product { Plasma = 0,NormalTV = 1 } concrete class of each vendor.... that returns each product and also the interface that contains ProductInfo i.e. if Vendor is ... then it must have this product....

  • Scala: "Parameter type in structural refinement may not refer to an abstract type defined outside th

    Hi, I'm having a problem with scala generics. While the first function I defined here seems to be perfectly ok, the compiler complains about the second definition with: error: Parameter type in structural refinement may not refer to an abstract type defined outside that refinement def >>[B](a: C[B])(implicit m: Monad[C]): C[B] = { ^ What am I doing wrong here? trait Lifter[C[_]] { implicit def liftToMonad[A](c: C[A]) = new { def >>=[B](f: A => C[B])(implicit m: Monad[C]): C[B] = { m >>= (c, f) } def >>[B](a: C[B])(implicit m: Monad[C]): C[B] = { m >> a } } } IMPORTANT: This is NOT a question about Monads, it's a question about scala polymorphism in general.

  • Eclipse "Add unimplemented methods" method ordering

    - by Steve Kuo
    Eclipse has a feature "Add unimplemented methods" that adds the unimplemented methods for a class (such as when implementing an interface). When Eclipse adds the methods it adds them in alphabetical order. Is there a way to configure Eclipse to add them in the order that they appear in the interface (or abstract class)?

  • How to extend abstract Entity class in RIA Services

    - by Calanus
    I want to add a bool variable and property to the base Entity class in my RIA services project so that it is available throughout all the entity objects but seem unable to work out how to do this. I know that adding properties to actual entities themselves is easy using .shared.cs and partial classes but adding such properties to the Entity class using similar methods doesn't work. For example, the following code doesn't work namespace System.ServiceModel.DomainServices.Client { public abstract partial class Entity { private bool auditRequired; public bool AuditRequired { get { return auditRequired; } set { auditRequired = value; } } } } All that happens is that the existing Entity class gets totally overriden rather than extending the Entity class. How do I extend the base Entity class so that functionality is available thoughout all derived entity classes?
