Note:
The file crdb_dictionary.dll must be installed before you can use dictionary
files in your reports.
Crystal Reports reads the dictionary file by using the P2ixbse.dll file. This
translation file is based on the xBase engine used to access dBASE, FoxPro
and Clipper databases, but it provides all the flexibility needed to read
dictionaries. See
dBASE, FoxPro, Clipper .
Note:
If you upgraded from an earlier version of Crystal Reports that allowed
dictionary files, the older dictionary files (.dct) were based on the Pervasive
engine. If you convert those older files to new dictionary files, the new files
will use the xBase translation layer instead of Pervasive. However, the
Pervasive engine installed by the earlier version of Crystal Reports must
remain on your system for the new dictionary application to read the older
dictionary files.
The Database Access layer is the layer through which the dictionary file
actually reads the original database data. Dictionaries must read database
data using the same routes that Crystal Reports uses to read the data. The
sections on direct access database layers and ODBC data sources describe
the files dictionaries need for reading data.
