Hi, I'm working on a c++ app and I'm facing a problem: I have a class B derived from the abstract class A that has some event handling methods. A third class C is derived from B and must reimplement some of B methods. Is there a way to implicitly call B's method before calling C's one? Class diagram: class A { virtual void OnKeyPr...

Is it over-rated especially when we talk about code-contract helping to do unit testing. I am specifically referring to contracts in .net 4.0. I use nunit for unit testing. ...

Its amazing how many programmers in the greater community of programmers ask questions like "How do I do an EXTJS backend?" or "How do I integrate jQuery with Java?", not understanding the distinction between the client and the server. Then I got to thinking, are there frameworks where the server actually sends JS or something to the cl...
Consider the following class structure: class Filter { virtual void filter() = 0; virtual ~Filter() { } }; class FilterChain : public Filter { FilterChain(collection<Filter*> filters) { // copies "filters" to some internal list // (the pointers are copied, not the filters themselves) } ~Filter...
I have a RequestHandler class and a RequestListener class. A RequestHandler creates a RequestListener and passes it a reference to itself. The RequestListener in turn calls methods on the RequestHandler to handle requests of different types when they are processed (eg handleTypeARequest(), handleTypeBRequest() and so on). Unfortunately, ...
