Btrieve

Crystal Reports connects to the Pervasive engine through the translation files P2bbtrv.dll and P2ctbtrv.dll.

The Btrieve engine is a complex collection of DLLs and EXEs that are specific to the version of Btrieve you are using. For more information on the different Btrieve engine files, refer to your Btrieve documentation.

Note:    

Btrieve DDF files

Crystal Reports does not determine the definitions of Btrieve data files directly from the data files themselves. It needs a set of Btrieve Data Dictionary Files (.DDF) that contain file, field, and index information. Crystal Reports uses Wbtrvdef.dll and Sbtrvdef.dll to parse these DDF files. The following are the required DDFs which must all reside in the same directory:

A set of DDFs normally contain definitions for multiple Btrieve data files. Once one of the DDFs is selected when creating a new report, Crystal Reports immediately adds all the data files defined in that DDF into the report. Crystal Reports also takes the path defined in the DDFs as the default path of the data files. The DDFs and data files can reside in different locations.

Note:    Be sure to study your Btrieve documentation for more information on Btrieve DDFs and on configuring the Btrieve engine.
