I need to be able to see if the incoming csv file had a head row different than the previous files header row. That will tell me that I have new columns.

Use a script task and use VB or C# to do the comparison.

The easiest thing to do would be to just read the first row as one large blob and save it. When the next file comes along, read the header as a blob and do a direct comparison to what you've saved using either "=" or "<>". That will certainly tell you if there's been a change.

If you need to isolate the column names as rows, read the header row and split it.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
