case if true 後面如果不用boolean, 而需要以string 呈現, 該如何修改? case if failed, 該如何用 one button dialog 來呈現error message? 非常感謝
Sorry if I am not quite understand your question/ problems
The Case if Error (Failed) is already a One Button Dialog. And, for Case if No Error (Passed), it is up to you how you want to process with the Input String, isn't it?
