About the ActiveX Controls

Pervasive's ActiveX interface is a set of nine custom controls that enable development environments that support ActiveX to easily access Btrieve data. The interface includes a data source control and eight bound data controls.

The Pervasive PSQL data source control provides the connection point between your application and a Btrieve data file. In addition to acting as a data source for other data-aware controls, the data control also exposes properties, methods, and events you can use to access data from code in your application-opening, closing, and creating files; and retrieving, updating and deleting records.

The Pervasive PSQL bound controls, which must be attached to the data source control, include data-aware text box, list box, combo box, check box and option button controls. The list and combo box controls operate either as field-bound controls or as multi-column record list controls.

Command button and horizontal and vertical scroll bar controls provide indexed record navigation.

In Microsoft Visual Basic, the Pervasive PSQL data source control can also act as a record source for data-aware Visual Basic controls, and for third-party data-aware ActiveX controls.
