Thread: Singleton Problems..

Hey all I have recently made a Singleton class directly from a book I recently purchased, Here it is:

Code:

class Singleton
{
public:
	 static void Create();
	 static void Destroy();
	 
	 static Singleton * GetInstance()
	 {
 	   		return s_pInstance;
	 }
	 
	 static int GetNum();
	   		 
protected:
		static Singleton* s_pInstance;
		
		//Hidden Constructor
		Singleton();
};

// Implementation
Singleton* Singleton::s_pInstance = NULL;

void Singleton::Create()
{
 	   if(!s_pInstance)
		   s_pInstance = new Singleton;
		
		   
}

void Singleton::Destroy()
{
 	   delete s_pInstance;
 	   s_pInstance = NULL;
 	   
}

However if I inherit from it with another class, I am not able to call any of it's own member functions, because of the Singleton Pointer.
My Book doesn't give much information on it, and I might be able to find a way, but I don't want to make many changes without being sure there isn't a better way.
Does any one have a suggestions?
PS: I'm a pretty new programmed, and I appreciate any help.

I am currently using the Dev C++ Software Compiler. The error message returned is..
Class Singleton has no member function named (Function).
