The application architecture claimed by the tool Appwizard includes four basic classes of applications, They are: Capp, cmainframe, cdoc, and cview. Among them, the system is responsible for the management of the entire application. The cdoc class has a pointer to the process scheduler. It can also be considered that the application is executed from the process scheduler. Cmainframe is the main window frame. Cdoc is an application data source (documen
