I can't believe that after all this time you would still post this without a complete exact copy of the error message and stack trace!

ps: please don't address these just to me... there are plenty of other skilled folk here who can help you.

pps: I just noticed lines 120 and 470-472. I not going to waste another microsecond on this until you run the code with sensible error diagnostics. I can't believe that after all this time you would still code an empty catch like that!

And, you want us to comment on 500+ lines of code? Sorry, but that isn't going to happen! Show us where the error is, and then we may be able to help you...

To be fair, 266 of those lines are GUI code generated by NetBeans, never intended to be read. It was pointless posting that part.

In the actual code the choice of member names is not so bad, so the code is not that hard to read.
Having said that, some explanation of what its all about would certainly be helpful.

In the interest of full disclosure: divinity02 and I have had many conversations over the years. She doesn't find programming easy, but makes up for it by hard work and persistence. I think that's worthy of support, so please don't be too harsh.

0

I’m not offended, no worries. No need to apologise.
Now, have you fixed the empty catch, and what is the message and stack trace from your error?
