I have a number of older spreadsheet applications which use the
recordset GetRows() method to fetch recordset data into a variant array
and then use
Range("Data").Value = varData()
to get the data into Excel.

MS KnowledgeBase article: 246335 - "How To Transfer Data from an ADO
Recordset to Excel with Automation" gives an example of doing this. It
also recommends the newer CopyFromRecordset technique for later
versions of Excel.

I have many older apps that use the Array technique, which I don't want
to re-code at this time.

The problem is that in Excel 2003, any date fields are interpreted as
American dates (mm/dd/yy) rather than Australian dates (dd/mm/yy) when
the data is put into the worksheet by Range("Data").Value = varData() .
Excel 2000 did not have the same problem.

Has anyone else had this problem, and know of a work-around?

The newer CopyFromRecordset technique works, but it will mean a lot of
re-coding.
