このプロパティを使用すると、ユーザーがアプリケーションで ENTER キーを押したときに実行される既定のアクションを指定できます。This property enables you to designate a default action to occur when the user presses the ENTER key in your application. このプロパティに割り当てられたボタンはIButtonControl 、現在のフォームにあるか、現在のフォームのコンテナー内にあるである必要があります。The button assigned to this property must be an IButtonControl that is on the current form or located within a container on the current form.

このプロパティを使用すると、ユーザーがマウスで [同意] ボタンを手動でクリックするのではなく、入力が終わったときに ENTER キーを押すだけで、単純なフォームをすばやく移動できます。You can use this property to allow the user to quickly navigate a simple form by allowing them to simply press the ENTER key when they are finished instead of manually clicking the accept button with their mouse.

フォームで現在選択されているコントロールが ENTER キーをインターセプトして処理する場合、[accept] ボタンがアクティブにならないことがあります。The accept button might not be activated if the currently selected control on the form intercepts the ENTER key and processes it. たとえば、複数行テキストボックスコントロールを使用すると、コントロールに改行文字を挿入するように選択したときに ENTER キーを押すことができます。For example, a multiline text box control allows the ENTER key to be pressed when it is selected to insert a new line character in the control.
