Abstract class without abstract methods

Question

Is it possible to make a class abstract in C++ without declaring any abstract methods? Currently, I have a Sprite class with a StaticSprite and DynamicSprite subclass. I would like to make the Sprite class abstract.

The problem is that there aren't any methods they share. Well, both StaticSprite and DynamicSprite might share a draw()-method, but the parameters of this method are different so this isn't an option.

Thank you!

EDIT: Here is the code to demonstrate what I'm trying to do:

Sprite:

class Sprite
{
    public:
        Sprite(HINSTANCE hAppInst, int imageID, int maskID);
        ~Sprite();

    protected:
        HINSTANCE hAppInst;
        HBITMAP hImage;
        HBITMAP hMask;
        BITMAP imageBM;
        BITMAP maskBM;
        HDC hSpriteDC;
};

Staticsprite:

class StaticSprite : public Sprite
{
    public:
        StaticSprite(HINSTANCE hAppInst, int imageID, int maskID);
        ~StaticSprite();

        void draw(Position* pos, HDC hBackbufferDC);
};

Dynamicsprite:

class DynamicSprite : public Sprite
{
    public:
        DynamicSprite(HINSTANCE hAppInst, int imageID, int maskID);
        ~DynamicSprite();

        void draw(HDC hBackbufferDC);
};

As you see, it's useless to create a Sprite-object, so I would like to make that class abstract. But I can't make draw() abstract as it uses different parameters.

You can declare your destructor as pure virtual, since all classes have one.

class AbstractClass
{
public:
    virtual ~AbstractClass() = 0 ;
} ;

However, you will need to define this destructor elsewhere.

AbstractClass::~AbstractClass() {}
