Hi,
I have a base usercontrol with a method (blank method, no code), I have
another few usercontrols that will inherit this base usercontrol, but I want
to force all the usercontrol that inheriting this base usercontrol to
override the method with its own code. How do I do it?
I have tried to make the base usercontrol an abstract class (mustinherits +
mustoverrides), this works, but all the usercontrols that inherit it will
not able...

Is it possible to have the constructor in an interface call member functions
polymorphically? For instance:
==============================
// INTERFACE CLASS
class SomeInterface {
public:
virtual void foo()=0;
SomeInterface() { foo();}
};

Hi
Been reading the GOF book and started to make the distinction between
Class and Interface inheritance. One question though:
Do pure abstract classes have representations? (data members?)
What about abstract classes?
Should abstract classes have a destructor and or constructor? What
about pure abstract classes?

Hello Everyone,
This is my first attempt at coding using an abstract class and i am
getting an error i can't figure out. Here is the back ground.
I have a project that contains an abstract class, it's namespace is
CIG.Intranet.Commons.User and it has 2 methods in it
public abstract getPropertiesHash (string userName) and
public abstract getPropertiesXml (string userName) adn the class name
is called
CPUser.cs

Hi,
When I update/add a new web reference to a web service class with a
parameterized constructor, what is preventing the generated proxy from
including a definition for the parameterized constructor as well as the
parameterless one?
Regards,
Peter

I am trying to figure out why it is not conventional to use protected
constructors in abstract classes since the only time they should be
called is by the constructors of it's derived classes. Is it simply
because it's not strictly necessary since an abstract class can't be
instantiated anyways? It just seems like it would be clearer to make
the ctor protected so I figured there must be some reason for it.
Also I am trying to put...

Hello All,
I have a simple question regarding the definition of abstract class,
IIRC , Abstract class is one which contains virtual function
declaration and other variables and no object of this class is created
directly.
If this is the case why don't we hide the constructor of abstract
class into protected region? So that only object which inherits it can
call the ctor of abstract class. In this way no one can create the
object of...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
