INF Files

Chapter Updated 11/21/23

INF File Details.

  • INF support is used to automatically open .NDX index files at table open time. Production MDX index files are opened automaticially at DBF file open time, but NDX index files are not. Using the INF option causes the NDX index file to be automatically opened.

  • Xbase64 INF support uses the same format of the INF files as created by the MS ODBC drivers for compatibility.

  • INF support requires the XB_INF_SUPPORT option be enabled at compile time.

  • Use method xbDbf::AssociateIndex() to update an INF file in your application program.

  • When using the SQL module, use the ASSOCIATE modifier to update the INF file.

    Example: CREATE INDEX ZipCode.NDX ON ZipCode.DBF( ZIPCODE ) ASSOCIATE;

    The above Create command results in an INF file with the name of ZipCode.INF to be created with the following contents:

    [dBASE]
    NDX=ZipCode3.NDX
