Except in the case where you want to support multiple versions of the same program that has an evolved object model over time. I am specifically talking about Microsoft Excel. Our software can talk to Excel 95 though Excel 2010 by querying it at runtime for the formats that it exposes. Tiresome but much more reliable than locking to a single version of Excel. Lynn
