Databinding with ActiveX Controls in Visual C++

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at Visual Studio 2017 Documentation. 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.
