simple question: how to do this ?

[mandatory]

Another question which puzzles me:

------------------------------------
Class A{
public:
virtual void func1(void);
virtual void func2(void);
virtual void func3(void);

};

Class B : Public A{
public:
virtual void func4(void);
};


B myclass;
----------------------------------------------

When i look at myclass, i can see all 4 memberfunctions - its superb.

But in my code for func4, in class B i want to call func1() - but >inside<
the class it doesnt seem to be visible ?

ex:

void B::func4 (void)
{
func1();
}

This doesnt work, it apparently doesnt know its derived func1() - how should
i solve this problem ?

There is no problem.
Everything should work as you expect it to be.
So the problem you face must be something else.
Can you provide a complete example and the error message
you get from your compiler?

You haven't said what led you to believe that it doesn't know. The code
you posted doesn't have any code for func1,func2,func3 which is maybe
what's confusing you (and us - sending code fragments isn't a good idea).
Try the following - it compiles/run for me.

class A{
public:
virtual void func1(void){};
virtual void func2(void){};
virtual void func3(void){};

};

class B : public A{
public:
virtual void func4(void);
};


B myclass;

void B::func4 (void)
{
func1();
}

int main()
{}

func1 is only declared. There is no implementation for it.

ex:

void B::func4 (void)
{
func1();
}

Implement func1().
