Thread: Using Pointers in Contained Classes

I would like to describe an example class hierarchy before I ask my question. I have an abstract class named Abstract. I have a class named UpperClass that was derived from Abstract. I have a class named LowerClass that is contained in UpperClass.

I find that I am able to pass a Abstract* down to LowerClass through the constructors. However, if I am not able to dynamic_cast the Abstract* to UpperClass* in a LowerClass member function. My Visual C++ compiler won't let me do a #include "UpperClass.h" inside lower class. Why is this? Why will C++ let me use a Abstract* in LowerClass but not a UpperClass*? How can I get around this? I need to be able to do this in LowerClass: UpperClassPtr->SomeOtherDataNotInAbstract;

Actually, if I'm understanding correctly, he may be doing this wrong. Would you be a good sport and post your code?

I am unable to post my code. Later today I will write an example program that convays my C++ problem. Thanks for the responses.

No biggy not being able to show the actual code, an example of the problem is a-okay by me.
