>The idea is not necessarily to turn your whole app into an object. Rather, utilize an 'application' object to take care of a lot of the housekeeping type things your app has to do.

>Application objects are usually subclassed from the container control and have methods to take care of menu handling, form handling, read events, clear events, saving and restoring environment settings, cleanup or whatever else you deem necessary. The reason that containers make the best application objects is because container can have other object as members, such as a security object or a user object.
>You can write an entire application without using an application object, all you need is a startup program that starts the main form, or main menu in the screen and issues a READ EVENTS, but if you decide to use an application object, your main program would look something like this:
