JetEngine Object (JRO)

Access Developer Reference

Provides control over Microsoft Access database engine-specific features such as compacting databases and refreshing data from the cache.


Use a JetEngine object to access features of the Jet database engine. A JetEngine object functions only when connected to a Microsoft Access database engine data source.

With the methods of a JetEngine object, you can:

  • Compact a database and modify other database properties with the CompactDatabase method.
  • Force pending data changes in the cache to be processed, ensuring that a recordset or the database is kept current, with the RefreshCache method.
