Leveraging Polymorphism

Project Name:	CMS12_2.vbp
File Folder:	Ex12_2

	This sample project demonstrates implementing an interface in two classes and then using the standard interface to leverage polymorphism. An object from either class is passed to a routine as a parameter that is defined to be the data type of the interface. This allows use of polymorphism without giving up early binding.
	The resulting application uses the default interface to set the properties for a Customer object and then passes the object to a Save method to save the properties. This process is then repeated for a Prospect object. This application does not actually save the data, rather it displays a message box.
	For a challenge, try the following:
- Implementing the IFile interface in the Customer and Prospect classes to replace the ISave interface.
- Leveraging polymorphism to save both the Customer and Prospect object data to a file.
