【问题描述】：

我在 Visual Studio (C++) 中有一个项目。该项目的前端是用 javaScript 编写的，它是在 chtmlview 窗口中运行的 C++ 的简单 GUI。

当项目在 Visual Studio 中以调试模式运行时，我得到以下信息：

从字面上看，这个口水的页面是从控制台出来的。我发现很难找到调试代码的方法。它必须在 chtmlview 窗口中运行，（而不是像 Chrome 这样可爱的东西，具有漂亮的调试能力......“是的，微软......你让我失望了），这使得它变得更加困难。我正在使用我的项目中我的 jQuery 的最新版本，除此之外，我有最少数量的 Try/Catches。

任何必须调试在 chtmlview 中运行的 javaScript 的人指出，将不胜感激。

其他症状包括窗户在整夜运行后运行缓慢。

（注意：我基本上是这个项目的脚本猴子，在 C++ 方面几乎没有输入，但最近重写了所有的 JavaScript；所以你可以看到我的这些异常让我感到尴尬！）。

【问题讨论】：

调试器配置有问题。检查一下。
谢谢，我现在看看一些指南。
您好，您使用的是什么版本的 Visual Studio？？

【解决方案1】：

在 Visual Studio 2015 中，您可以配置希望调试器处理哪些异常。
