Hello, I don't have problem with Prolog itself.
I worked with Turbo Prolog 1 and 2 in the 80' and I loved it. I have realized and sell, via the "Faculté des science de Paris", a medical expert system. It was a mix of TP and the Turbo C from Broland too. His price was proposed by IBM and his IA service ( Tour Franklin / Paris )...
Today, I spend many hours and days trying to understand how I can create a dialog ( or a form ) and then send in a listBox contained in it the results I get correctly, as displayed in the "message window"...
I looked at ALL the exemples to seek and find such an exchange between two dialogs or so, I test many combinations with code in ***.i or ****.cl or ****.pro files and I get ALLWAYS the same answer :
The object member 'listBox_ctl' is used in the class predicate !
A simple call frmm one "dialog" to an other dialog is correct as traced... Fine !!! But as soon I call a local predicate to send a list via the listBox_ctl I get each time this error.
I really tried everything but, of course, not the good one !
Please.... a basic exemple : a form with a listBox_ctl and a predicate callable externally to let me display results in it.
As we said in France "Merci d'avance" and, also, Warm regards. Michel
