Databinding with ActiveX Controls in Visual C++

Databinding is implemented through two types of ActiveX controls: data controls and data-bound controls.

• Data controls
  A data control is responsible for encapsulating a database query and the retrieved rowset. The Microsoft data 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 controls: ADO and RDO.

  Important

  ADO and RDO data controls are an older technology that was released in a earlier version of Visual Studio, and might not be available in the current version. To use the information in this section, you might have to obtain a earlier release to acquire the appropriate control.

• Data-bound controls
  A data-bound control is responsible for presenting the data. Data-bound controls connect to data 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.
