My program progresses through each row of a worksheet, using the values as parameters to a database procedure.
If a user were to press the Esc key, the transactions would sit in an uncommitted state.
If the user were then to re-reun the processing, duplicates or contraint errors would result.

The solution was to use EnableCancelKey to trap the Esc key and Rollback the transactions.
