Subject How to validate data before a post and cancel that operation eventually?
Author G. Nau
I'd like to do some validations and calculations on a dataset, just
before the post is performed.
How can i do that? IB_Query.beforepost,
IB_datasource.onupdatedate, IB_Datasource.ondatachange?

How can I cancel the post operation if I find an error in the entered
data? Is there an "abort" method available?
