推荐答案

您的应用程序是单线程的.当它运行任务时，没有线程可以继续响应Windows消息.如果您在另一个线程中执行任务，则在运行该消息时将看不到该消息.较便宜的选择是在应用程序正在运行的任何循环内添加Application.DoEvents()行，这将导致它每次到达那里时都处理消息.

Your application is single threaded. While it is running it''s task, there is no thread to keep responding to windows messages. If you perform your task in another thread, then you won''t see that message while it is running. A cheaper option is to add the line Application.DoEvents() inside whatever loops your app is running, which will cause it to process messages each time it gets there.
