I have many math types like Point3, and I am running into the dilemma of implementing operators, instance and static methods for arithmetic. So say the type is Point3. Where a, b, c is a Point3, I sure wanna be able to say: c = a + b; But should I also implement: c = Point3.Add (a, b); And this: c = a.Add (b); To me #3 is usele...
Hi, Having an assembly which I cannot modify (vendor-supplied) which have a method returning an object type but is really of an internal type. How can I access the fields and/or methods of the object from my assembly? Keep in mind that I cannot modify the vendor-supplied assembly. In essence, here's what I have: From vendor: intern...

I would appreciate any help as C++ is not my primary language. I have a template class that is derived in multiple libraries. I am trying to figure out a way to uniquely assign an id int to each derived class. I need to be able to do it from a static method though, ie. template < class DERIVED > class Foo { public: static int s_id...
My application has a button to execute a python script dynamically using execfile.

I read When to Use Static Classes in C# but the top answer didn't necessarily answer my question. I've an application that interfaces with quite a bit of similar hardware, via an HTTP server. Each device must be logged into and the credentials are normally the same. I'm using Properties.Settings.Default.etc to handle application wide set...
Given that each php file in our project contains a single class definition... any suggestions for determining what class was defined within the file? I know I could just regex the file for class statements, but I'd prefer to do something that's more efficient. Suggestions? Thanks ...
When you derive from a class and instance the subclass, the runtime also instances the super class, right? Since abstract classes can't be instanced, are they not created by the runtime when a subclass is instanced? If so, then abstract class inheritance would be faster than normal class instance? ...
I'm working on some effects and things to get a handle on Classes/Implements/Extends.

class Test1<T> { Test1(Class<T> type) {} } class Test2 extends Test1<Class> { Test2() { super(Class.class); } } This works, but, I am warned about use of a raw generic type in "Test1<Class>".

I'm using boto to manage some EC2 instances. It provides an Instance class. I'd like to subclass it to meet my particular needs. Since boto provides a query interface to get your instances, I need something to convert between classes. This solution seems to work, but changing the class attribute seems dodgy. Is there a better way? from ...
