I'm implementing enumeration using a base class that defines a variety of methods. The actual enumerations are subclasses of that, with no additional methods or attributes. (Each subclass is populated with its own values using the constructor defined in the base class). I use a registry (a class attribute that stores all the instances o...

Hi, The problem I'm facing is that I'm trying to manipulate (in this particular case add eventListeners) objects (in this case some MovieClips) on the stage from a class that isn't the document class. 1120: Access of undefined property trans. Now I know that it's probably a scope thing and I probably can't access stage objects direct...
<?php class Student { public $name = "Benjamin"; } $name = new Student(); ?> <p>Hello, there. My name is <?php $name->name ?></p> The above code doesn't work as intended (printing the name within "p" tags).

I want to do make a public member in a base class private in a derived class, like this: class A { public: int x; int y; }; class B : public A { // x is still public private: // y is now private using y; }; But apparently "using" can't be used that way. Is there any way to do this in C++? (I can't use private...

What does it mean: Object's observable state? I was reading yesterday in "Exceptional C++" Solution to item 43 and there is a fragment: private: void InvalidateArea() { area = -1; } Even though this function modifies the object's internal state, it should be const. Why? Because this function does not modify the object's observabl...
