ISet.GetWorkbook Method
If the set is opened somewhere, e.g. it is the current set in the Set manager,
the workbook is retrieved from this opened copy of the set. This local workbook may contain
changes by a user that were not stored in the database yet.
The returned workbook is connected to the set. Any changes in the workbook are
automatically reflected in the opened set.
Otherwise, if the set is not opened, the workbook is read and created directly from database.
To explicitly store your changes to the database, you need to
call WriteWorkbook method.
