このプログラムは、ユーザーからの入力を受け取り、テキストファイルに入れ、必要に応じて（まだ実装されていない）情報をプルできるようになっています。プログラムが開いて値を取り込んで保存しますが、プログラムを終了すると新しいウィンドウが表示され、これが繰り返されます。これをやめる方法についての助け？それはちょうどどこかで欠けている休憩かもしれないが、私は私の人生のためにそれを修正することはできません。プログラムを閉じようとするとループします。この無限ループを修正するにはどうすればよいですか？

それを試しましたが、何も変わりません。私はしばらくの間、条件を変更する必要があると信じていますが、それを何に変更するかはわかりません。 – Chief
