Hello there, I have something like that (simplified) class A { public: virtual void Function () = 0; }; class B { public: virtual void Function () = 0; }; class Impl : public A , public B { public: ???? }; How can I implement the Function () for A and the Function() for B ? Visual C++ lets you only define the s...
Whenever i override a method of a base class, other than my implementation of this method, i seem to have 3 choices. 1) Call base.Method(), and then provide my implementation. 2) Provide my implementation and then call base.Method() 3) Just provide my implementation. Recently while using a library i have realized few bugs that were i...
I would like to roughly monitor the progress of a file upload. I know that I can override the MultipartEntity and make the writeTo(OutputStream out) method write to a FilterOutputStream class that I created to wrap the default InputStream. For full details on how I did that, see my answer here. However, upon closer inspection this coun...
This is similar to This question but the answer doesn't solve my problem. I want to register a default implementation for an interface in code but be able to override that in a config that is read BEFORE the code is run. I want to do something like if (!container.IsImplementationRegistered(typeof(TInterface)) { container.RegisterTy...
I have a class (Wall) that inherits from Sprite. Sprite already has width and height properties. But for wall, I need to do some other additional calculations when the properties change (f.e. make sure the new size won't cause it to overlap any other walls). So, how do I set the width property inherited from the Sprite class from withi...
Why is the FxCop rule CA1061 a bad idea? The docs state that this rule should not be suppressed. If I have class like so: public class Set<T> { List<T> m_backingList; public bool Contains(T value) { return m_backingList.Contains(value); } } then I add a specific implementation like this: public class C...
How can I switch to a different theme template file for any node that I want? I understand how to create sub-themes like node-recipes.tpl.php for a node that has a path of "recipes". But what I want to have control of the entire base template like page.tpl.php. Can I use some preprocess function in template.php for this? Right now I hav...
I have a class named PageBase inheriting from ASP.NET Page. I want to do something in PageBase's Page_Load. All pages in my application have their logic done on their Page_Load. I'm thinking of a way that Page_Load of both of PageBase and other pages run without having to override Page_Load in pages. Is it possbile? ...
Hello, It appears that the args object passed into an override of OnPreviewMouseLeftButtonDown describes the current (live) mouse button state, not a snapshot of the state present when the event occurred. Is this proper behavior? Shouldn't event arguments reflect event data at the moment the event occurred (a snapshot) and not be autom...
When I use ruby 1.8.7 Net::HTTP.post_form(URI.parse(URL), params), I found it has a bug, see : http://stackoverflow.com/questions/3214502/how-to-send-an-array-with-nethttp-post-form My code is a regular ruby script, and I want to override that method(net/http.rb#set_form_data) like this: require 'net/http' require 'uri' module Net ...
Is there a way to create a class that derives from XElement, but also control the types of objects that can be added to it? For example, say I have this... public class HtmlHead : XElement {} But I can't override the Add() method because it's down at the XContainer level. And even if I was to create a class that derives from XContain...
Say I have a namedtuple like this: fooTuple = namedtuple("fooTuple", "item1, item2") And I want the following function to be used for hashing: fooHash(self): return hash(self.item1) * (self.item2) I want this because I want the order of item1 and item2 to be irrelevant (I will do the same for the comparison-operator). I thought...

I got two objects from the same class and I need to compare them field by field. The problem is that they have close to hundred fields and it would be helluva work to write that by hand. Do you know any way to do that the easier way? Reflections in Java could be a solution, but yet it seems to me like a hack. And I seek a C# solution af...

Hi Is there a possible way to override the paintComponent() method in the auto-generated GUI code in NetBeans? I managed to manually draw a graph without using the drag-and-drop components, and I need to make adjustments (e.g. adding radio button group) which I find really time consuming and tedious work. I created a GUI using the Net...
