Hello, DaniWeb,
I'm trying to get better at troubleshooting, so I'd like to see what process other people go through.
I have three communication devices that aren't working in my program... a connection to a MySQL database, a keylistener, and a treat feeder.
On the other hand, some other communication devices are working... a mouselistener, a touchscreen, and the monitor.

Is there a general relation between the things that are working or the things that aren't working, or should I try to hunt down the individual problems?
Some of my code is available under my previous thread, "I lack focus". It's a large, unwieldy program and I'd rather not post all of it or repost the part that I did, unless you really need to see it.
That's all I got.
