How are you integrating your current application into Swing?
And, as Fred has asked, what is on line 85? Or that DBMS_Test_GUI class in general?
I just performed a second installation of NetBeans in another PC with Windows 8.1.
I created a new Swing project and a simple JFrame form with only a button.
I also copied my classes to the Swing project.
I wrote code for the button in the JFrame form to instantiate my 3 classes, called some methods, and it worked perfectly.
I do not know why it is working now. The only difference I see is that one PC has Windows 10 and the other Windows 8.1.
Well, there is another difference. In my Windows 10 PC I ran my JFrame form several times before copying my classes. In my Windows 8.1 PC, I copied my classes and then ran the Swing project for the first time.
Is there anything special in how I ran the project?
Best regards.
