USING COLLECTIONS

As mentioned earlier, every form in your application usually has a number of controls. To reference a control, you first have to reference the form. Because a form can consist of many controls, these related controls are grouped together in a collection object.

Collections are a special type of property that consists of related objects. For example, your database consists of a collection of tables, and each table has a collection of fields and indexes. There are now two data access methods for accessing these collections: Data Access Objects (DAO) and ActiveX Data Objects (ADO). These will be discussed in Chapter 5, “Working with Data Access Objects,” and Chapter 6, “Introducing ActiveX Data Objects.”
