Hi ,

I am running into a couple of errors in developing an app that uses
the data access application block and datasets- so I am assuming this
is ADONET related. :)

When I do an add to a dataset and then update the dataset back to the
MSDE database, it will update the backend database alright, but right
after that i get an error about a null dataset argument being
passed.

When I do a delete on the dataset and update the backend database, I
get a concurrency violation and it does not delete as a result.

The table has a timestamp field to help in the process of updating
because data access application block recommends it.

Am I getting the error because of inappropriately placed
'acceptchanges' commands? Or what else might cause these types of
errors?

Thanks for whatever help anyone can provide.
