can that be done? I have a base class A then I derive a class B from that now, can I derive a class C from B? when I try I get error C2504: ''B'' : base class undefined anyone have done anything alike, please mail an example or explain how to do it thanks

Of course you can!

Check if you have included the .h file where you define class b.

If you have, try to foredeclare(does this word exist? xD)it.That is:


class B;
/*THIS TELLS THE COMPILER THAT YOU WILL DEFINE CLASS B LATER ON*/

class C:public B
{
...........
};

What the hells!
