Notice how the constructor Z does not actually use its parameters directly Instead, in this example, they are simply passed along to the constructor functions for X and Y There is no reason, however, that Z could not use these or other arguments

The last change required for column sorting is to update the CurrentAlbum property for our comparer field whenever the contents of the ListView control are refreshed. This ensures that our Compare implementation performs the proper comparison based on the contents of the control.

Before moving on to virtual functions and polymorphism, it is necessary to explain a unique attribute of pointers and references that provides their foundation We will begin with pointers In general, a pointer of one type cannot point to an object of a different type However, there is an important exception to this rule that relates only to derived classes In C++, a base class pointer can point to an object of a class derived from that base For example, assume that you have a base type called B_class and a type called D_class, that is derived from B_class In C++, any pointer declared as type B_class * can also a point to an object of type D_class For example, given

UPDATE THE CURRENTALBUM PROPERTY WHEN REQUIRED Action 10 Update the LoadPhotoData method to assign the current album to the comparer. Result

B_class *p; // pointer to object of type B_class B_class B_ob; // object of type B_class D_class D_ob; // object of type D_class

private void LoadPhotoData(PhotoAlbum album) { . . . _albumsShown = false; _album = album; _comparer.CurrentAlbum = _album; . . . }

the following is perfectly valid:

0833 to 3054 m (12 m/s), 0972 to 3560 m (14 m/s); [0623to2284 ma(090m/s)] 06 m 011 m 06 m(12 m/s), 07 m(14 m/s) 03 m 8/14 (8/17 w/merge bits) CIRC (CIRC7a) 23%/34%c 1014 25 mm 200 to 500 rpm 12 to 14 m/s (090 m/sa) 43218 Mbps (86436 Mbpsa) 141 Mbps/123 Mbpsc

p = &B_ob; // p points to object of type B_class p = &D_ob; /* p points to object of type D_class, which is an object derived from B_class */

UPDATE THE CURRENTALBUM PROPERTY WHEN REQUIRED (continued) Action 11 Update the LoadAlbumData method to assign a null album to the comparer. Result

Using p, all elements of D_ob inherited from B_ob can be accessed However, elements specific to D_ob cannot be referenced using p (unless a type cast is employed) This is because the pointer only knows about the members of its base type even though it can point to derived types For a concrete example that uses base class pointers, consider this short program, which defines a base class called B_class and a derived class called D_class The derived class implements a simple automated telephone book
