  • Explicit C# interface implementation of interfaces that inherit from other interfaces

    - by anthony
    Consider the following three interfaces: interface IBaseInterface { event EventHandler SomeEvent; } interface IInterface1 : IBaseInterface { ... } interface IInterface 2 : IBaseInterface { ... } Now consider the following class that implements both IInterface1 and IInterface 2: class Foo : IInterface1, IInterface2 { event EventHandler IInterface1.SomeEvent { add { ... } remove { ... } } event EventHandler IInterface2.SomeEvent { add { ... } remove { ... } } } This results in an error because SomeEvent is not part of IInterface1 or IInterface2, it is part of IBaseInterface. How can the class Foo implement both IInterface1 and IInterface2?

  • Checking to see if a generic class is inherited from an interface

    - by SnOrfus
    I've got a class that inherits from an interface. That interface defines an event that I'd like to subscribe to in the calling code. I've tried a couple of things, but they all resolve to false (where I know it's true). How can I check to see if a class implements a specific interface. Here's what I've tried (note, the object in question is a usercontrol that implements MyInterface, stored in an array of controls, only some of which implement MyInterface - it is not null): if (this.controls[index].GetType().IsSubclassOf(typeof(MyInterface))) ((MyInterface)this.controls[index]).Event += this.Handler; if (this.controls[index].GetType().IsAssignableFrom(typeof(MyInterface))) ((MyInterface)this.controls[index]).Event += this.Handler; if (this.controls[index].GetType() == typeof(MyInterface)) ((MyInterface)this.controls[index]).Event += this.Handler; All to no avail.

  • Interface builder problem: When hooking up an IBOutlet, getting "this class is not key value coding-

    - by Robert
    Here is what I do: 1) Create New UIViewController subclass , tick with NIB for interface builder 2) In the header: @interface QuizMainViewController : UIViewController { UILabel* aLabel; } @property (nonatomic, retain) IBOutlet UILabel* aLabel; @end 3) In the .m #import "QuizMainViewController.h" @implementation QuizMainViewController @synthesize aLabel; - (void)dealloc { [aLabel release]; [super dealloc]; } @end 4) Open the NIB In interface builder, drag a new UILabel into the view. I test the program here and it runs fine. 5) right click on file's owner, connect 'aLabel' from the Outlets to the UILabel. I run here and it crashes. Message from log: * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key aLabel.'

  • Persist collection of interface using Hibernate

    - by Olvagor
    I want to persist my litte zoo with Hibernate: @Entity @Table(name = "zoo") public class Zoo { @OneToMany private Set<Animal> animals = new HashSet<Animal>(); } // Just a marker interface public interface Animal { } @Entity @Table(name = "dog") public class Dog implements Animal { // ID and other properties } @Entity @Table(name = "cat") public class Cat implements Animal { // ID and other properties } When I try to persist the zoo, Hibernate complains: Use of @OneToMany or @ManyToMany targeting an unmapped class: blubb.Zoo.animals[blubb.Animal] I know about the targetEntity-property of @OneToMany but that would mean, only Dogs OR Cats can live in my zoo. Is there any way to persist a collection of an interface, which has several implementations, with Hibernate?

  • Unresolved symbol when inheriting interface

    - by LeopardSkinPillBoxHat
    It's late at night here and I'm going crazy trying to solve a linker error. If I have the following abstract interface: class IArpPacketBuilder { public: IArpPacketBuilder(const DslPortId& aPortId); virtual ~IArpPacketBuilder(); // Other abstract (pure virtual methods) here... }; and I instantiate it like this: class DummyArpPacketBuilder : public IArpPacketBuilder { public: DummyArpPacketBuilder(const DslPortId& aPortId) : IArpPacketBuilder(aPortId) {} ~DummyArpPacketBuilder() {} }; why am I getting the following error when linking? Unresolved symbol references: IArpPacketBuilder::IArpPacketBuilder(DslPortId const&): ppc603_vxworks/_arpPacketQueue.o IArpPacketBuilder::~IArpPacketBuilder(): ppc603_vxworks/_arpPacketQueue.o typeinfo for IArpPacketBuilder: ppc603_vxworks/_arpPacketQueue.o *** Error code 1 IArpPacketBuilder is an abstract interface, so as long as I define the constructors and destructions in the concrete (derived) interface, I should be fine, no? Well it appears not.

  • How do I write an overload operator where both arguments are interface

    - by Eric Girard
    I'm using interface for most of my stuff. I can't find a way to create an overload operator + that would allow me to perform an addition on any objects implementing the IPoint interface Code interface IPoint { double X { get; set; } double Y { get; set; } } class Point : IPoint { double X { get; set; } double Y { get; set; } //How and where do I create this operator/extension ??? public static IPoint operator + (IPoint a,IPoint b) { return Add(a,b); } public static IPoint Add(IPoint a,IPoint b) { return new Point { X = a.X + b.X, Y = a.Y + b.Y }; } } //Dumb use case : public class Test { IPoint _currentLocation; public Test(IPoint initialLocation) { _currentLocation = intialLocation } public MoveOf(IPoint movement) { _currentLocation = _currentLocation + intialLocation; //Much cleaner/user-friendly than _currentLocation = Point.Add(_currentLocation,intialLocation); } }

  • c++ "interface"-like classes similar to Java?

    - by William the Coderer
    In Java, you can define an interface as a class with no actual code implementation, but only to define the methods that a class must implement. Those types can be passed as parameters to methods and returned from methods. In C++, a pure virtual class can't be used as a parameter or return type, from what I can tell. Any way to mimic Java's interface classes? I have a string class in C++, and several subclasses for different encodings (like UTFxxx, ISOxxx, etc) that derive from the base string class. However, since there are so many different encodings, the base class has no meaningful implementation. But it would serve well as an interface if I could handle it as its own object and calls to that object would call on the correct subclass it was inherited to.

  • Interface with generic parameters- can't get it to compile

    - by user997112
    I have an interface like so: public interface MyInterface<E extends Something1> { public void meth1(MyClass1<E> x); } and I have a subclass whose superclass implements the above interface: public class MyClass2<E extends Something1> extends Superclass{ public MyClass2(){ } public void meth1(MyClass1 x) { // TODO Auto-generated method stub } } superclass: public abstract class Superclass<E extends Something1> implements MyInterface{ MyClass1<E> x; protected E y; public Superclass(){ } } the problem is that the parameter for meth1() is supposed to be generic. If I do MyClass1 it doesn't like it and the only way I can get it to compile is by leaving out generic parameters- which feels wrong. What's going wrong?

  • Perl - Choose interface to connect through

    - by Dieterve
    I have 2 interfaces on my server, eth0 and eth0:0. Those are 2 different external ips and obviously 2 different reverse domains. When i open a IO::Socket::INET Perl uses the eth0 interface by default. I would like to use the second interface (eth0:0) because this has a different ip and i dont want to use my main ip/domain. I have absolutely no idea how to select which interface to connect through. Code i use to open a socket: my $sock = new IO::Socket::INET(PeerAddr => $server, PeerPort => $serverPort, Proto => 'tcp') or die "Can't connect to server: $!";

  • Use one NIC to create multiple interfaces for Linux KVM

    - by Phanto
    I am working on a thesis research project, and I am having some difficulty figuring out how to make one NIC spawn several "bridge" interfaces such that each KVM VM can be seen on the local network. I am very new to KVM, and am still exploring what it can do. Below is the scenario that I am attempting to make (on a CentOS/RHEL 6 system): Linux KVM Host has 1 NIC (eth0) connected to a switch. Create multiple "bridge" or equivalent interfaces that are spawned off of eth0 that would provide a unique IP for each VM. This is so that each VM can communicate with other hosts on the network, and that other hosts on the network can communicate with the VM. IMPORTANT: I would like iptables on the KVM host to be able to manipulate/control/restrict the traffic that would be sent on those "bridge" interfaces. I would like to create a minimum of three VM's, each using their own unique "bridge" interfaces. I have previously made a br0 interface off of eth0, but unfortunately, I am unable to add any more to it. It appears that you can only bridge 1 interface to the NIC. I would like to bridge many to one. Would a tap device be able to do this? If so, how would it be set up? Effectively, I am attempting to replicate what can easily be created with VirtualBox on Windows, where each VM is given a "bridged" interface, and can live on the network. I want to achieve this very same thing with Linux KVM. Thank You EDIT: To be more descriptive, I want to achieve something that looks like this: This can be found on this page: http://en.gentoo-wiki.com/wiki/KVM#Networking_2 HOST +---------------+ | | KVM GUEST1 | | +--------------+ | +------+ | | | LAN ---+--- eth0 | +--+---+---- nic0 | KVM GUEST2 | | tap0----+ | |192.168.1.13 | +--------------+ | | tap1----+ | +--------------+ | | | +------+ | | | | | br0 +--+----------------------+---- nic0 | |192.168.1.12 | |192.168.1.14 | +---------------+ +--------------+

  • Multiple WAN interfaces on SonicWall TZ 100?

    - by Chad Decker
    I'm using a SonicWall TZ 100 with a basic configuration of X0 for the LAN and X1 for the WAN. The WAN uses DHCP to obtain its routable IP address. I want to obtain a second routable IP from my ISP. I'm in luck because my cable company will provide me with an additional dynamic IP for $5/mo. How do I bind this IP to my SonicWall? My additional dynamic IP will not be consecutive to the original one. It won't even be on the same class C. I think what I want to do is to use one of the empty ports/interfaces (X2, X3, or X4), tell that interface to use DHCP, and then add that interface to the WAN "zone". I can't figure out how to do this though. Here's what I've tried so far: (1) I've looked in Network Interfaces. I see X0 and X1 but the other unused interfaces don't show up. I don't see an "Add" button to add the new interfaces. (2) I've looked in Network Zones. I see that X0, X2, X3, X4 are in the LAN zone. I tried to drag X3 into the WAN zone but I can't. Nor does clicking the "Configure" button allow me to move an unused interface from LAN to WAN. (3) I've read the post entitled Splitting up multiple WAN's on Sonicwall. This doesn't seem applicable to me. Any thoughts?

  • Enabling Multiple Monitor Support from Terminal Services/Remote Desktop over Citrix

    - by Nicolas Webb
    Our Remote Desktop/Terminal Services solution where I work relies on Citrix for machines not connected via the VPN. We're using Citrix Xen server (I'm pretty sure) and I'm going to try to connect to a Windows 7 Host (my work computer) and I think the RDC client runs on a Win2003 host (exposed via Citrix). Is it possible to take advantage of Windows 7 multiple monitor support for RDC with this setup? Would I need to try getting my Citrix guys to have a different host machine for the RDC (Win2008, or Win7?)? I'm probably going to connect using the OS X Citrix client, but I'd be willing to BootCamp/Fusion up a Windows instance to work remotely, as well. I really want to be able to use multiple monitors remotely. It does "span" multiple montiors currently (I have a 3000x1024 desktop, for example) but I'd rather it be "true" multiple monitor instead of one giant desktop, if possible.

    - by user793553
    On July 13, 2012, we plan to upgrade the My Oracle Support HTML-based user interface (UI) with additional functionality that will allow those users remaining on the Flash-based user interface to switch over to the HTML version. Our goal is to provide a single-online support portal so that all My Oracle Support users can benefit from the same features and functionality. Prior to July 13, 2012, users of Oracle On Demand, Oracle CRM On Demand, Taleo, and Oracle Configuration Manager should continue accessing the My Oracle Support Flash-based user interface. After July 13, 2012, the above features and functionality to support these users will be available on the HTML interface. All other users of My Oracle Support can make the switch now. Benefits of using the HTML-based user interface include: Streamlined, three-step process for initiating new Service Requests (SRs) Single, consistent workflow for both hardware and software incidents Enhanced personalization and filtering within the user interface New accessibility features (enabling screen readers, large fonts, etc.) Additionally, please note Internet Explorer 6 (IE6) will no longer be supported. For further information, please check Doc ID 1385682.1

  • Interface builder UIButton custom background image not working on simulator/device

    - by xenonii
    I'm trying to do something really simple. I have an image for a button and I'm trying to set it on a custom button in interface builder. I set the background image accordingly (no case sensitivity problem here). In interface builder it shows up, but in the simulator or on the device it doesn't appear at all. Just the button's text will appear. Do I need to turn on some flag or something of the sort?

  • Interface Builder can't see classes in a static library

    - by teabot
    I have refactored some UIView sub-classes into a static library. However, when using Interface Builder to create view components for a project that uses the static library I find that it is unaware of the library classes. What do I need to do to make the class interfaces visible to Interface Builder? Update: The correct answer refers to dragging the headers into the 'XIB browser'. The '.h' files can be dragged from a finder window to the window area identified in this image:

  • Common header view on top of nib files with Interface builder

    - by Tiago
    Hi, I have a nib file that contains an header that will be used in most of my views, so that I can change it's layout just once when I need. I'd like to know if it's possible to add the header nib view with interface builder, or if I need to do that programmatically and how should it be done. I've thought about setting the subclass of the subview to a UIView subclass that automatically loads the nib file, but I'd like to do that with interface builder. Is that possible?
