Given the following code: public interface IExample { ... } public abstract class BaseExample: IExample { ... } public class ExampleA : BaseExample { ... } public class ExampleB : BaseExample, IExample { ... } Are there any benefits or drawbacks in writing code like ExampleB? My guess is that re-specifying IExample in the derived cl...
In Java, I'd like to be able to define marker interfaces, that forced implementations to provide static methods. For example, for simple text-serialization/deserialization I'd like to be able to define an interface that looked something like this: public interface TextTransformable<T>{ public static T fromText(String text); public...
Can some one explain the exact use of interfaces in C# ? ...
I have a generic class that is also a mapped super class that has a private field that holds a pointer to another object of the same type: @MappedSuperclass public abstract class MyClass<T extends MyIfc<T>> implements MyIfc<T> { @OneToOne() @JoinColumn(name = "previous", nullable = true) private T previo...
Were dealing with some pretty custom UI elements while building our OSX / Cocoa and iPhone / IPad apps. I was wondering if anyone has good recommendations or tricks for getting a better workflow between UI designers and coders while using Xcode / Interface Builder? It seems that many things require programmatic settings with UI editing...
Hi All, I want to customize the project page (trac/templates/index.html). I want to use a table to show more project-specific information. For instance the admin list of each project, the build status of each project. These information are stored in trac's database. I am afraid that the default template engine is not able to give me ...
I've found that Linq2Sql doesn't (Rhino) mock well, as the interfaces I need aren't there. Does EF generate code that's more mockable? NOTE: I'm not mocking, yet, without interfaces, the next reader of this question may not have my bias. EDIT: VS2008 / 3.5 for now. ...
On a machine with multiple network cards I need to bind a WCF webservice to a specific network interface. It seems that the default is to bind on all network interfaces. The machine has two network adapters with the IPs 192.168.0.10 and 192.168.0.11. I have an Apache running that binds on 192.168.0.10:80 and need to run the webservice o...
Let's say I'm defining a game class that implements two different views: interface IPlayerView { void play(); } interface IDealerView { void deal(); } The view that a game sees when playing the game, and a view that the dealer sees when dealing the game (this is, a player can't make dealer actions and a dealer can't make play...

i have a menu item, and i'm trying to assign its OnClick event handler: miFrobGizmo.OnClick := {something}; The OnClick event handler property, like almost every other event handler, is defined as a TNotifyEvent method type: property OnClick: TNotifyEvent where TNotifyEvent is: TNotifyEvent = procedure(Sender: TObject) of object;...
i have a method: procedure Frob(Sender: TObject); that i want to call when i click a menu item. The method comes to me though an interface: animal: IAnimal; IAnimal = interface procedure Frob(Sender: TObject); end; The question revolves around what to assign to the OnClick event handler of a menu item (i.e. control): var a...
I modified my data source in my LINQ-to-SQL class (by the old delete and drag back in method), and was surprised to see the INotifyPropertyChanging & INotifyPropertyChanged interfaces no longer implemented in the generated classes (MyDb.designer.cs). The methods for the individual fields went from looking like this... [Column(Storage="...
Say, I have three interfaces: public interface I1 { void XYZ(); } public interface I2 { void XYZ(); } public interface I3 { void XYZ(); } A class inheriting from these three interfaces: class ABC: I1,I2, I3 { // method definitions } Questions: If I implement like this: class ABC: I1,I2, I3 { public voi...
Hi, I am an experienced .NET developer but new to EF - so please bear with me. I will use an example of a college application to illustrate my problem. I have these user roles: Lecturer, Student, Administrator. In my code I envisage working with these entities as distinct classes so e.g. a Lecturer teaches a collection of Students. An...

A dual interface in COM is one that is able to be accessed via a DispInterface or via VTable methods. Now can someone tell me what is exactly what the difference is between the two methods? I thought that a VTable is a virtual table which holds the pointers to the different functions when implementing a class hierarchy which has virtua...
Greetings all, I’m working on a C# program that requires being able to get the index of the hot item in Windows 7 Explorer’s new ItemsView control. Fortunately, Microsoft has provided a way to do this through UI Automation, by querying custom properties of the control. Unfortunately, the System.Windows.Automation namespace inexplicabl...
