I am using my application delegate to swap out views. First I remove the current view, then I add the new view, then I run a quartz animation. No matter what view I load first, the orientation changes occur as expected. As soon as I start adding new views (removing the old) to the window in the application delegate, orientation changes ...
Hi, I transitioned from Java 1.4(previous company) to Java 1.6 (new company). What I have observed that in case of 1.4 most of the proprietary frameworks were defined using interfaces and template patterns, whereas with 1.6 most of the frameworks are defined around generics. While I am still trying to get a grip around Generics, my q...
So i have a interface class class interfaceClass { public: virtual void func1( void ) = 0; virtual void func2( void ) = 0; protected: int m_interfaceVar; } and a class that inherits from it. Why can't i set the member variable of the interface class as follows. class inhertitedClass : public interfaceClass { inher...
Hi , I like to know can we define an interface within an interface. like interface abc { void show(); public interface xyz { void read(); } } This was question asked in interview. Any real time use of this. ...
For some classes of a static C++ library I want to offer different interfaces for the user of the library and for the library itself. An example: class Algorithm { public: // method for the user of the library void compute(const Data& data, Result& result) const; // method that I use only from other classes of the lib...

I have a data provider project to access the database. this is composed by various classes (PersonDataProvider, JobDataProvider ...) I want to create an Interface. Do I have to create an Interface for each class? I was tempted to create one interface and than inherit on all the classes. This involves making all the projects classes part...
I'm in the process of planning a web service, which will be written in C++. The goal is to be able to select more or less any web server to drive the service. For this to become true, I obviously have to choose a standardized interface between web servers and applications. Well known methods that I've heard of are: CGI FastCGI W...

I'm playing around with some classes and interfaces, and have developed a simple method to determine the hierarchy of a class, i.e. to identify the chain of inheritance. public static void OutputClassHierarchy(Type ty) { if (ty.BaseType == null) { Console.WriteLine("{0}: Base", ty); Console.WriteLine(""); ...
I need someone to confirm what I am seeing before I may a change to the domain of the application because of this issue. The issue is that when databinding against interfaces that inherit from one another, you can not see the properties on the base interfaces. I am working on a WinForms application that uses databinding. This is in .net...
The more detail I put in an interface, the less reusable it is. On the other hand the less detail the more ethereal and useless it seems to become. Is there a standard set of recommendations about how to weigh this for various situations? ...
Using AVD, I successfully obtained the USB driver. I followed the instructions on this page USB Driver for Windows but Windows never prompted with the "Found new hardware..." message. I'm running Vista x64 SP2 and I can see the amd64 folder under ~\Android SDK\tools\usb_driver. The Manage Devices applet shows no listing for "ADB Inter...
I don't necessarily see a grandiose benefit of interfaces inheriting interfaces. Consider the following three interfaces, the third inheriting the other two interface IOne { } interface ITwo { } // interface inheritance interface IAll : IOne, ITwo { } Is it best to class C : IOne, ITwo { ... } or class C : IAll { ... } If th...

I'm just about to write my first application in a duck typed language (Groovy). If I was to write the same application in a static typed language then I would need to define some interfaces. Obviously because of the duck typing in Groovy they are not actually required. At the moment I am thinking that it might make sense to define them ...
If I have three classes class A class B extends A class C extends A Would using abstract classes or interfaces give me any type of errors or affect the way I implement the program? ...
I use Unmanaged Exports to create a native .dll from .NET .dll so I can access .NET code from Delphi without COM registration. For example I have this .NET assembly: using System; using System.Collections.Generic; using System.Text; using RGiesecke.DllExport; using System.Runtime.InteropServices; namespace DelphiNET { [ComVisible(t...
