How to Use GENDBC to Create Utility that Recreates Complex CDX (135112)

SUMMARY

Gendbc.prg is a program file that is included with Visual FoxPro and is used to generate code for the purpose of rebuilding a database container (.DBC) file. It is installed by default in the VFP30\Tools\Gendbc directory. Once this program is run with your database open, it will generate code that will recreate the .DBC file, any tables and indexes, and any persistent relations that exist in the database. If any changes are made to the structure of your database, you must rerun Gendbc.prg for the changes to be reflected in the code generated by it.

NOTE: The resulting generated program is primarily used in case your database container becomes corrupt. It will rebuild the structure; however, lost data is irrecoverable. It is a good idea to back up your data on a regular basis. For more information on Gendbc.prg and its use, please see the online documentation or help file.
