So where is the code for the AddRecord class? Specifically the no-arg constructor, and any init code it calls? I am not going to read your entire codebase, but the relevant parts look OK so far.~Tim

# 2
dont use so many setVisible(false) msges in actionPerformed event.close the addRecord window just by closing a button in that window itself

# 3
first write a simple action performed event ,only by calling AddRecord class , afterwards u include other action buttons

And that is the God's Honest Truth.

I'm afraid that this is beyond my ability to help with, as I refuse to wade thru that much IDE Generated code to figure out what all is wrong with it. At a glance, there is a ton wrong, not the least of which is the fact that AddRecord does not need and should not have a main method.

Good luck with this. You might want to set this aside, and go thru the Sun Swing Tutorial first before even attempting to write any more code, and forget about using NetBeans to build your GUI for you.

remove the thread codes , setVisible False methods ,compile and run the AddRecord class alone , try until u get window ,slowly debug and fix the prob, if u get the window automatically u create the object in ur MainMenu class.

How is it that you can spell "automatically" but not "you" or "your"?

You did it again! You managed to spell "fluent" but not "sorry"?! Oh well...

I will explain it if you promise to start spelling you "y-o-u"!
