Description

The DBC_CLOSEDATA database event is triggered by the closure of a database and runs dbc_closedata.prg (.dbo compiled/runtime) if it exists. The code is run before the database is actually closed. Databases are closed using the CLOSE DATABASES command.

The following parameters are passed to the dbc_closedata program:

Parameter Description
<expC> The database name
<expL1> Specifies whether the ALL keyword was included on the CLOSE DATABASES command, .T. or not, .F.

If the dbc_closedata program returns .F., the database is not closed, if .T., the close operation continues.

Programs associated with database events should reside in the database's directory. These can be created and modified from the Events tab in the Data Workspace when a database is open.

Example

// dbc_closedata.prg
lparameters cName, lAll
close procedures
