Re: polymorphic use problem

If I have these classes:

class TBase
{
public:
    virtual int Execute(Server* srv) = 0;
    virtual ~TFunction() {}
};

class Derived : public TBase
{
public:
    Derived(const std::string& strA, int ia1)
    : m_strA(strA), m_ia1(ia1){
    }

    virtual int Execute(TServer srv)
    {
        return SomeFunction(srv, m_strA, m_ia1);
    }
    ~TRegister() { }
private:
    std::string m_strA;
    int m_ia1;
};

I want to call the Execute function on a Derived object. How can I
call it?
