'Are you sure?' custom dialog not exiting cleanly

Desktop wxRuby
1

The following program does not exit cleanly after pressing ‘Yes’ when
asked
‘Are you sure’?
How do I free up the resources after exiting? You can use wxsugar
(xrcise)
to try out this mini program
if you wish to create sample1.rb . Thank you.

It looks like you either need to make the confirmation dialog a child of
the main frame of the whole program, or else call dialog.destroy
explicitly when you’re finished with it, whatever the return value of
show_modal

def confirm_closure
# dlg = DIA_Frame.new
dlg = DIA_Frame.new(the_main_window)
if(dlg.show_modal==Wx::ID_YES) then
dlg.end_modal(Wx::ID_YES)
self.destroy
end
end
