Hi, I'm trying to place a UIImageView in a UITableViewCell. I create a special view called ProductView. In that view, I have several components, one of them being a UIImageView. I set this ProductView as content view of the UITableViewCell. Everything is drawn properly except the UIImageView. UIImageView gets scaled meaninglessly. It's...
I want to apply a function to every element in a list (map) but the elements may have different types but all implement the same function (here "putOut") like an interface. However I cannot create a list of this "interface" type (here "Outputable"). How do I map a list of different types implementing the same function? import Control.M...
Is it correct practice to add Javadoc comments in Interface and add non Javadoc comments in the implementation? Most IDEs generate non JavaDoc comments for implementations when you auto generate comments. Shouldn't the concrete method have the description? ...
I have a UDP socket that is bound to INADDR_ANY to listen to packets on all the IPs my server has. I'm sending out replies through the same socket. Right now the server chooses automatically which IP is used as the source IP when packets are sent out, but I would like to be able to set the outgoing source IP myself. Is there any way to...
Every time I build my C# Solution, I get a handful of warnings about interfaces that I've never seen or written. I tried Googling for some of them, but get no hits. Could these possibly be buried in an assembly I'm referencing? If so, is there any way to make these warnings go away? Interface 'IAlertable' is marked as [dual], but ...
I have written a generic type: IDirectorySource<T> where T : IDirectoryEntry, which I'm using to manage Active Directory entries through my interfaces objects: IGroup, IOrganizationalUnit, IUser. So that I can write the following: IDirectorySource<IGroup> groups = new DirectorySource<IGroup>(); // Where IGroup implements `IDirectoryEnt...
Imagine the following interface in C#: interface IFoo { void Bar(); } How can I implement this in F#? All the examples I've found during 30 minutes of searching online show only examples that have return types which I suppose is more common in a functional style, but something I can't avoid in this instance. Here's what I have s...
Hi, I have just started learning Scala and I'm now wondering how I could implement two different Java interfaces with one Scala class? Let's say I have the following interfaces written in Java public interface EventRecorder { public void abstract record(Event event); } public interface TransactionCapable { public void abstrac...
interface IFoo { int MyReadOnlyVar { get; } } class Foo : IFoo { int MyReadOnlyVar { get; set; } } public IFoo GetFoo() { return new Foo { MyReadOnlyVar = 1 }; } Is the above an acceptable way of implementing a readonly/immutable object? The immutability of IFoo can be broken with a temporary cast to Foo. In general (...
The Problem It's something I came across a while back and was able to work around it somehow. But now it came back, feeding on my curiosity - and I'd love to have a definite answer. Basically, I have a generic dgv BaseGridView<T> : DataGridView where T : class. Constructed types based on the BaseGridView (such as InvoiceGridView : Bas...
Hello, I had created an interface to abstract a part of the source for a later extension. But what if I want to extend the derived classes with some special methods? So I have the interface here: class virtualFoo { public: virtual ~virtualFoo() { } virtual void create() = 0; virtual void initialize() = 0; }; and one derived class ...
I'd like do implement a generic function with the generic constraint that the Type passed in is an interface. Is this possible in C#? I have it working fine without the constraint, but the code will fail at runtime if it is not an interface, so I'd like to have the compile time checking. public T MyFunction<T> where T : {any interface...
Considering that a processor runs at 100 MHz and the data is coming to the processor from an external device/peripheral at the rate of 1000 Mbit/s (8 Bits/Clockcycle @ 125 MHz), which is the best way to handle traffic that comes at a higher speed to the processor ? ...
In C#, I have a class hierarchy with a couple of abstract base classes near the top and a fair number of derived classes. A few these concrete classes have some common properties and methods that are implemented identically. It strikes me as wasteful and so one solution might be to implement this common behaviour in another abstract ba...
Hey, everybody.I'm beginning. I used Xcode + Interface Build to set up a Project on the bases of Tab bar. And now I want to draw support from three20 to realize Tab bar's view, that is to say, when click "item", the view from three20 will display. So I want to know how to insert "Three20 Project" to Tab bar Project? ...
Hi, I've got an interface: package com.aex; import javax.jws.WebParam; public interface IFonds { double getKoers(); String getNaam(); void setKoers(@WebParam(name="koers") double koers); } And the class: /* * To change this template, choose Tools | Templates * and open the template in the editor. */ package com...
I am looking for a good open source professional css design layout interface to use in my web-based system. Maybe something similar to an XP classic theme. Does anyone know such a theme? ...
Hey I'm currently attempting to read information about an object from the web.config file and create and object based on that. However, I only wish to be able to create objects from classes that extend a particular interface (IModule). The type of the object is coming from a type attribute in the web.config: <module moduleAlias="Test...
Hi, I get answer in: http://stackoverflow.com/questions/3084125/object-modelling-problem that I should use interface instead class Extra in this case: public Extra { public bool Paid {get;set;} public string Name {get;set;} public string Code {get;set;} } class Car { private List<Extra> _listOfExtras=new List<Extra> public List<Ext...
I'm trying to get around dual inheritance in C# by re-implementing one of the parent classes as an interface with extension methods. The problem I'm encountering is that event EventHandler<EventArgs> Disconnecting; public static void OnDisconnected(this AutoConnectClientBase target) { target.ClientConnectionStat...
