The arrangement is like this:
I drop an TBQuery onto my TFrame
This IBQuery I set to "allow auto activate transaction".
With new frames I had a problem of which I am not sure, how I solved it, because I tried much and copied a working thing into a non-working or so.
The problem was this:
In the property of the IBQuery there was nothing to choose in the field of database. If I key it in by hand, it did not work. And this is the reasong, why I hesitate to delete this
"uses mydatamodul"
I fear, that the stuck-situation will return, that the Frame / IBQuery does not allow me to set the database-property, if I delete the db-module out of the uses-clause.
The data-modul IS used. I get from there: database1, connection1, transaction1
(and.: Thank you so much to the IBX-creators, it works that great and easy once it is set up!)
