You need to implement the static New function and have your
constructor and destructor protected. Here is the smallest example of
a class that I use vtkSmartPointer with in VS2008.

class smvtkMarkerData : public vtkObject
{
public:
	vtkTypeRevisionMacro(smvtkMarkerData,vtkObject);	
	static smvtkMarkerData*	New();

	typedef vtkSmartPointer< smvtkMarkerData > Ptr;
protected:
	smvtkMarkerData();
	~smvtkMarkerData();

public:
	smPropertyMap*	getSMProps();
	bool			setSMProps(smPropertyMap* pProps);
	bool			isReadOnly();
	void			setReadOnly(bool bReadOnly);
	void			PrintSelf(ostream& os, vtkIndent indent);

private:
	class		smPrivate;
	smPrivate*	m_pPrivate;

private:
	smvtkMarkerData(const smvtkMarkerData&);	// Intentionally Not implemented.
	void operator=(const smvtkMarkerData&);		// Intentionally Not implemented.
};
