Visual studio compiler supports this keyword [^] and above all,if a person happens to use VS, "it works" without "any additional implications".

Making the c'tor private will certainly stop the class from being inherited but it will also force the person to provide 'other' way of creating the class object.

I think OP wanted to stop inheriting not instantiation. And my suggestion only helped him do what he wanted - nothing more, nothing less.

Which means that it is not a C++ program! It is a C++/CLI program, that targets the .NET framework.

Now certainly, it's david vs big-fat-goliath(that's you) given my insufficient knowledge about managed or unmanaged code

"sealed is also valid when compiling for native targets (without /clr)"

I feel it's working on my PC.

class c1 sealed{}; class c2:public c1{};

class A sealed
{

};
class B: public A
{

};

I only have 2003 installed here on this PC and it doesn't just work right. I will be able to derive classes from a class that has been declared 'sealed'.

So, my suggestion is not entirely wrong. It works in at least one case. Laugh

It doesn't even seem to know what does 'sealed' mean.

class CSealed
{
   CSealed(){}
   CSealed(const CSealed& ref){}
};

class some:public CSealed
{
   //whatever
};

int _tmain(int argc, _TCHAR* argv[])
{
   some s;
   return 0;
}

can we make class cant be derived at all? if yes how to make it. please let meknow?
