By using the DATAMGR.EXE Data Manager program provided with Visual Basic,
you can do all this:
- Create a database
- Create new tables
- Create an index
- Open an existing database
- Add fields to a table
- Modify table data
- Delete an existing table
- Compact a database
- Repair a database
The Data Manager gives you a subset of the features found in Microsoft
Access for Windows. Data Manager, Visual Basic, and Microsoft Access all
create the same database format, an .MDB file. An .MDB file contains the
database structure as well as the data itself.
The documentation for Data Manager is found in Data Manager's Help menu.
