Databinding is implemented via two types of ActiveX controls: data-source controls and data-bound controls.
Data-Source Controls
A data-source control is responsible for encapsulating a database query and the retrieved rowset. The Microsoft data-source controls provide a user interface consisting of a series of buttons to iterate through the data. Visual C++ offers two data access technologies for data-source controls: ADO and RDO.
Data-Bound Controls
A data-bound control is responsible for presenting the data. Data-bound controls connect to data-source controls to receive data and present the data through a variety of user interfaces. A Visual C++ application can also bind variables to data values set in the data-bound controls; see CWnd::BindProperty.
