In this chapter, you've seen how you can use the WFC package to enhance your apps; examined the IByteStream family of classes, including its most important member File; and learned how the constructors of File provide the same fine-grain control as file type objects in other Visual languages. In addition, we examined the IReader/IWriter family of classes, which are designed to provide easy access to ANSI text input and output.

For simplicity's sake, I've limited the discussion so far to console apps. Windowed apps use the WFC package in exactly the same way.

will look at the WFC Utility ( package. Once again, we can examine the majority of this package while remaining under the simplifying confines of the console app. Comments
