Hi all,
Two things:
One: TDataset.Recordcount on Delphi (TclientDataset?) returns 0 if it's called on an inactive TDataset. But an exception seems to be more appropiate to me. But some dataset-descendents raise an exception, some return 0.
Now what should I do in sqldb and the TMemDataset?
Two: I want to document the choice I made in point one, and I think that the writing documentation at the same time is a good idea. But now I have this question: TDataset.Recordcount always return -1. Even if the TDataset is closed.
Any comment on the exception in, for example, TMemDataset.Recordcount, should I place that in the TMemDataset.Recordcount-help? Or can I put into the TDataset.Recordcount a remark, that most TDataset.Descendents return 0 or raise an exception?
Normally you would write that down in the documentation of the descendent, but I want to make a statement to TDataset-descendent- developers, that if they make their own descendent, it should return 0 or an exception. where's the place to do that?
I hope my point is clear.
Regards,
Joost.
