The com.ms.wfc.app package contains many classes that provide WFC application services. Many of these operations belong to the Application object itself. These operations have mostly to do with creating threads, starting the application, handling application events, and so on. Because understanding Java threads is important, it is discussed in its own section, Using Java Threads with WFC.
Other operations that qualify as application services pertain to those provided by the Win32 operating system. These include accessing the Windows registry, accessing Clipboard data, and retrieving system information, among other operations.
