Description

The Application class provides a diverse range of functionality, including support for multithreaded programming, access to the system registry, and support for subclassing (intercepting messages sent to application windows). It also includes a variety of informational functions, such as properties to retrieve the company name, to retrieve the application's executable path, and to retrieve the application's name and version. Members of the Application class are shared and do not require an object instance for use.
