推荐答案

当您的应用程序没有终止时，您应该查看项目的CWinApp部分，例如InitInstance()和ExitInstance().

When your application doesn''t terminate, you should look in the CWinApp part of your project, e.g. InitInstance() and ExitInstance().

CDialog :: OnClose() ;

CDialog::OnClose();
PostQuitMessage(0);

删除CDialog::OnClose()和PostQuitMessage(0);

而是调用CDialog::OnCancel()来关闭基于对话框的应用程序.

另一位发帖人提到，某些工作线程可能正在运行，从而使应用程序保持活动状态.错了这样的事情在本地语言程序(如C ++)中永远不可能发生.当主线程停止运行时，所有其他线程都会突然终止.

Remove CDialog::OnClose() and PostQuitMessage(0);

Call CDialog::OnCancel() instead to shut down a dialog based application.

Another poster mentioned that some worker thread may be running, keeping the app alive. That''s wrong. Such a thing can can never happen in a native language program (like C++). When the main thread comes to a halt, every other thread will be killed abruptly.

您是否在此应用中使用UI线程以外的任何线程?

如果是，则那些其他线程可能仍在运行并保持应用程序打开.

希望对您有帮助

Are you using any threads other than the UI thread in this app?

If yes those other thread(s) might still be running and keeping the application open.

Hope this helps
