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.
