介绍

我想知道当我的程序因意外异常而挂起时如何自动创建转储文件。

背景

有很多关于如何使用Window Command或Windbg程序创建转储文件的文章。

但是我的程序已经被设置为客户的计算机，所以我不能告诉他“当程序没有响应时你应该自己制作一个转储文件。

使用代码

要运行此程序，您需要使用cdb.exe文件。您可以在附件文件中找到。或者您可以在互联网上将其下载为“Windows软件开发工具包”。安装时，应检查“Debuggin Tools for Windows”项。这些文件包括在内。您也可以使用windbg.exe文件而不是cdb.exe。如果你使用它，windbg窗口将打开并运行。
