推荐答案

请参阅我对问题的评论.两个字:不好的主意.对话框的目的非常不同.充其量，您会让用户疯狂.更糟糕的是，如果您确实使用了一个线程，则该应用程序看起来会挂起，尤其是当有人激活某个其他应用程序的窗口然后尝试激活您的应用程序时.您实际上应该在单独的线程中执行任何耗时的操作.

Please see my comment to the question. Two words: bad idea. And the purpose of the dialog is very different. At best, you would drive your users crazy. Worse, if you really use one thread, the application would look hanging, especially if someone would activate a window of some other application and then try to activate yours. You should really do any time-taking operation in a separate thread.
