I make two JFrame. "one.java" for send value to "two.java". when i clicked "Send to two" button on the "one.java" it getting the "one" Text Field values and send to "two.java" and set it correctly. That process working well!!!
As well it is working for other way. I mean first run the "two.java" and click "Send to one" then it set that values on "one.java" You can see it on netbeans.
But in my case one.java is main one. two.java is child one. So i want to when open two.java by pressing Send to two button, send back text field values from two.java to one.java pressing Send to one.
Hope you got my point. I am not good at for explain very well. Exactly i want to pass text field value from child Jframe to main Jframe when child one opened by main jframe. At that time two Jframes are running. User can see two jframes.
Hope you got it. Please kindly fix my problem. If you can complete it do it for me. Now i am 3 days trying to do this. But finally i writing for you.
Here I post my code.
