// __declspec(novtable) is used on a class declaration to prevent the vtable
// pointer from being initialized in the constructor and destructor for the
// class.  This has many benefits because the linker can now eliminate the
// vtable and all the functions pointed to by the vtable.  Also, the actual
// constructor and destructor code are now smaller.
///////////////////////////////////////////////////////////////////////////////
// This should only be used on a class that is not directly createable but is
// rather only used as a base class.  Additionally, the constructor and
// destructor (if provided by the user) should not call anything that may cause
// a virtual function call to occur back on the object.
///////////////////////////////////////////////////////////////////////////////
// By default, the wizards will generate new ATL object classes with this
// attribute (through the ATL_NO_VTABLE macro).  This is normally safe as long
// the restriction mentioned above is followed.  It is always safe to remove
// this macro from your class, so if in doubt, remove it.
