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.
Install the ActiveX controls by running
setup.exe. You can
choose Typical, Complete, or Custom installations. The Typical installation
omits the MSI redistributable files found in the Complete installation. For more
information about ActiveX, see the ActiveX section of the Pervasive Developer
Center at http://www.pervasive.com/developerzone/access_methods/activex.asp
The installation will then proceed to install the following ActiveX
components to the
\pvsw\bin directory for a Typical or Complete
ActiveX Data Access Control
ActiveX Bound Controls
Meta data handling DLL

|52379||DdfPath, Location, and Join buttons cannot be operated from the keyboard.|
|53342||The ActiveX controls do not update LONGVARCHAR type fields. They read existing data, but if you change the field and do an update/insert, status returns success, but the field has not changed. I This is not a new issue with 9.5 (all 9.x versions have it) but it would be great if it could be resolved.|
|53378||ActiveX does not support the entire range of BigInt values. This is also an issue in previous Pervasive PSQL versions.|
|53784||ActiveX does not support the GUID/UNIQUEIDENTIFIER data type.|
|53785||ActiveX does not support the DateTime data type.|
