exportFileToDatabase Example

The exportToDatabase program creates a logger, opens a logger tape, and exports it to a MS Access database.

You must have a MS Access data source named "Logger MS Access ODBC" (or change the code accordingly). See the User Guide for instructions on how to set up the data source.
