Hi,

This a newbie question :o) :

I have a class :

class firstClass {
public:
   firstClass(a, b);
    ......
    (vars declaration)
    ( functions declaration)
}

and another one :

class nextClass : public firstClass {
public:
    nextClass(a, b);
    .....
    (vars declaration)
    ( functions declaration)
}

and i want to call the constructor of firstClass in nextClass.
I know i can do :

nextClass ::nextClass(a,b)
    : firstClass(a,b)
{
    ....
}

but i want to call firstClass directly in the {} because a need to make some
init before.
Can you help me ? if i use firstClass(a,b) in the {}, i have an error :
illegal use of abstract class

thanks
Chris
