thanks,
that is not what is happening. the edits are actually done in a
wwrecordviewdialog and the edit checks also
the onclose event of this dialog i assign to these variables the resulting
field content.at that time the content is correct no need to further edit.
I assign some flags, then assign the field values to variables.
then insert a new record and assign it's field with the variables and post.
I think this is where i'm not posting correctly.
but you mention a IBOdatabase component, I don't have one in my datamodule
, can that be a problem, how do connect/use a IBOdatabase and i have a
transaction component , or is the default transaction ok, and how should I
use it?
this application was a conversion from a progress DB,BDE to IBO and IB/FB
and I not to familiar with the workings of IBO(obviously,but learning)
can I still insert IBODatabase and connect in the datamodule?
