推荐答案

首先，您应该使用有意义的名称来命名您的对象-Button1在您使用时不会告诉您任何内容正在阅读代码，而btnGo或btnForward等告诉您一些信息.

您的进度条不起作用，因为您没有在任何地方进行更新...通常，进度条没有Click事件，您可以在代码进行过程中对其进行更新，以向用户指示事情正在发生. ..

First of all, you should really name your objects with meaningful names - Button1 tells you nothing when you are reading through the code, whereas btnGo or btnForward etc tells you something.

Your progress bar isn''t working because you aren''t updating it anywhere... Generally a progress bar doesn''t have a Click event, you update it as your code progresses to indicate to the user that things are happening...
