The Island Hopper News application includes one section that is developed as a sample, the classified ads section. Other sections of the newspaper, such as news and sports, provide context. Two different versions of the classified ads application are included with Visual Studio, Level A and Level C. These levels are described later in this section. You can install either of the levels and work with them to understand the pieces of each application, how they fit together, and how they were put together. For installation prerequisites and instructions, see the Visual Studio Samples Page in MSDN Library Visual Studio 6.0.
Level A is a simple implementation that includes both a Windows and a Web client application. The two clients have identical functionality. Level A demonstrates both browsing and placing ads into a database. This level would be suitable for a small company intranet, because it does not support multiple users accessing the database at once. You can look at the two clients of Level A as reflecting a migration from a standard, Windows-style user interface to a Web interface.
The tools and technologies demonstrated in Level A include:

Level C is a full-fledged implementation that includes two client applications: a Web-based client for browsing and placing ads and a Windows client for updating customer records, invoices, and payments. Level C, which expands Level A by adding support for billing and security, would be suitable for the Internet.
The tools and technologies demonstrated in Level C include:
