I'm trying to do an insert and update of a record in a serviced component.
When I call these methods, I get an InvalidCastException: Unable to cast
object of type System.__ComObject to type System.Data.DataSet. Inside these
methods, there's really just the basic insert/update stuff. Attaching to my
component doesn't work anymore. So I can't step through the code. Executing
a select works well.

I'm using framework 1.1.

Where does this error come from? Is this some problem with datasets and
serviced components?

Thanks in advance,
Pieter
