Example 1: Performing multiple directory substitutions (HFSQL data files)

The following example is used to perform some directory substitutions:

for data files described in the "Current directory"
for data files described in a specific directory (C:\File).

// Close all data files before changing directory
HClose("*")

// Change directory for data files defined in
// the "current directory" in the analysis
HSubstDir(".", "d:\file")

// Change directory for data files defined in
// a specific directory in the analysis
HSubstDir("c:\file", "d:\file")

// Open/create data files in the new directory
HCreationIfNotFound("*")

Example 2: Changing the database name (OLE DB)

This example is used to change the name of the database. The name of the database specified in the analysis is "c:\Access\MaDatabase.mdb." However, on the client's workstation, the name of the database is not necessarily identical (e.g., "d:\My Documents\DataBaseClient.mdb").

HSubstDir enables you to change the name of the database that will be used by all the OLEDB tables associated with a connection on the "c:\Access\MyDatabase.mdb" database.

// Close all data files before changing directory
HClose("*")

// Change the name of the database
// here an Access database: MaDataBase.mdb
HSubstDir("c:\Access\MyDatabase.mdb", "d:\My Documents\CustomerDatabase.mdb")

// Open/create data files in the new database
HCreationIfNotFound("*")
