Sounds like you're abusing the dataset as a local cache. If you want to cache your data locally, consider using a local database and a synchronization framework; it'd save you a lot of redundant calls. Alternatively, you can find all that has been added using plain SQL; perform a SELECT WHERE NOT IN and pass the values for the primary keys of the records in your dataset. Deleting would be something similar. For updates, one could use a timestamp (think "lastmodified"-field). Bastard Programmer from Hell :suss: If you can't read my code, try converting it here[^]

You'd get more responses if you'd; Copy the code that you wrote (part with the question-marks) here Can give an example of a couple of teachers and where'd you like to distribute them (the datastructure) I'd also mark it as VB6-code, as most people will be expecting VB.NET as it's got a comparable syntax. You already did that :-D I are Troll :suss:
