Welcome!

pxlib is a simply and still small C library to read and write Paradox DB files. It supports all versions starting from 3.0. It currently has a very limited set of functions like to open a DB file, read its header and read every single record. It can read and write blob data. The write support is still a bit experimental.

Features

  • Reading/writing Paradox DB files
  • Reading/writing of primary index files (.PX)
  • Recoding of character fields
  • Reading/writing blobs (.MB files)
  • Reading/writing encrypted files, even without knowing the password

Software that uses pxlib

There are currently two larger open source projects using pxlib:

  • gnumeric,
  • knoda (hk_classes).

The gnumeric plugin is written by the author of pxlib itself and is currently able to read paradox databases which do not contain any blobs. Write support will be available in gnumeric 1.7.0 if the patch in the bug database will make it into the code in time.

knoda uses pxlib through its database abstraction classes hk_classes. Recent versions have also added support for writing and modifying paradox databases.
