I wonder if somebody could explain the need/purpose of Flag property of
Column object.

I am building a component in VB 6 which will use DTS objects to import data
from Excel
to SQL 2K and export from SQL 2K to Excel. The DTS package is build at
run-time. There
is only one think I don't understand, how to obtain Flag property for Source
and Destination
columns. Is Column.Flag property the same as ADO Field.Attributes? Can I
just ommit this
property when generating Transformation object at runtime?
