VB & VBA in a Nutshell: The Language

BindingCollection Object (VB6)

Description

The BindingCollection object—as the name suggests—is a collection of Binding objects. The BindingCollection object plays a central role in the new data-binding technology in VB6, allowing you to automatically map data fields to standard form controls and to specify formatting for those data. Your application can have any number of BindingCollection objects, each referring to a distinct data member provided by a data source such as an ADO recordset or a VB data source class. The Binding objects held within the class represent the individual mapping of consumer control property to data provider field, a relationship created using the BindingCollections Add method.

The relationship between the various data binding elements is shown in Figure 7.1.
