在不弹出对话框的情况下终止基于MFC的C ++

问题描述

我们有一个旧的基于MFC的C ++ gui应用程序（Visual Studio 6.0），该应用程序通常无法正确终止。因此，我希望能够使用“ abort（）;”之类的指令。立即结束。

但是，abort（）指令会导致一个对话框弹出，而不是立即结束。使用“ exit（int）”无效。

是否有消除中止对话框的方法，还是有更好的终止方法？

解决方法

如果它是基于对话框的应用程序，则可以使用EndDialog（IDOK）方法。

一种明显的中止方式，无需任何其他任何提前操作即可调用Windows ExitProcess函数：

如果要从某个外部程序中将其杀死，则可以使用ExitProcess(exitCode); 来执行。为此，您需要一个流程句柄，这通常意味着获取其流程ID。如果您是通过生成了要杀死的程序的程序来执行此操作的，则在创建该程序时可能会得到该程序的句柄。否则，您可能需要使用类似TerminateProcess的东西来找到其窗口，然后使用FindWindow来寻找该窗口的进程的ID。有了它，您就可以呼叫GetWindowThreadProcessId来获得句柄，最后呼叫OpenProcess来杀死它。

打开对话框时，另一个线程是从其父进程创建的，而exit（0）函数仅杀死父进程，而不杀死对话框线程。因此，您应该首先使用EndDialog（）函数，然后调用exit（0）终止父进程。 它将起作用。
