Please trace your code and find out what is causing it to stay at the last
record instead of allowing Eof to be true. Perhaps there is an event or
control attached.

As Jerry pointed out, the TDataset allows the last record to appear as being
current (as far as data controls presentation goes) even when the dataset
has the Eof property flagged as true. In IBO you only get Eof true when you
are fully scrolled off the last record, which means the visual controls
would need some way to show the record pointer being at Eof, rather than the
last record.

This is the difference between IBO native and IBO TDataset.

I think your issue is different than Jerry's. Your's most likely has to do
with events or property settings keeping it from scrolling to the Eof spot.

Subject: [IBO] bug with eof ?


Hi I have this simple code and the problem is that it will never found
the Eof condition.

TIB_Query *tbl = static_cast <TIB_Query*> (dmUsers->queUsers);

if (!tbl->Prepared) tbl->Prepare();
tbl->First();
while (!tbl->Eof){
//some action
tbl->Next();
}

the SQL of the IB_Query has the following:

SELECT ID
, ID_USUARIO
, HUELLA
, NOTAS
FROM USUARIO_HUELLAS


What I am doing wrong?

please give me any advice

best regards
