Hi, I''m having problem with a dynamic cast, which by my opinion should be succesfull:
class BaseC{
public:
	BaseC() {MessageBox(NULL,"BaseC Constructor", "Constructor", MB_OK);}
	virtual ~BaseC() {MessageBox(NULL,"BaseC Destructor", "Destructor", MB_OK);}
};

class DerivedC : public BaseC {
public:
	DerivedC():m_val("Works!") {MessageBox(NULL,"DerivedC Constructor", "Constructor", MB_OK);}
	virtual ~DerivedC() {MessageBox(NULL,"DerivedC Destructor", "Destructor", MB_OK);}
	void TestFunc() {MessageBox(NULL,m_val, "Constructor", MB_OK);}
private:
	char* m_val;
};

//then:


	 BaseC *baseObject = new DerivedC();

	 DerivedC *derivedObject = dynamic_cast<DerivedC*>(baseObject);
	 
	 if(derivedObject != NULL) {
		derivedObject->TestFunc();
	 }
This gives me a RunTime error on the dynamic_cast. But from what I have read it is supposed to work like this?? thx!

Have you enabled runtime type info on your compiler? At least in VC++.NET 2002 RTTI is not enabled on default.
