michel if u just want to issue the update then u just need to do ocommand.ExecuteNonQuery() and this will return the number or rows that got updated.
you don't need to use a dataadapter for that, the fill command should be only used to fill a dataset with the selectcommand.

>>So, you do an UPDATE and then do a SELECT to re-populate your DataSet with the newly updated data? I suppose that that's an ok methodology (in case there were other updates to the existing data), but we don't currently do that in our existing app. We *may* have to re-think that for the new app we're working on, but at the moment I've not thought much about it.
