c++ - 如何在visual studio 2008中进行调试

Question

我一直在为外部库 cpp 文件中的错误获取这些行号，我无法知道我的代码的哪一部分导致了这个错误。有时它甚至会在崩溃的地方显示汇编代码片段......

如何获取我自己的代码导致此错误的行？或者至少是我的代码的哪一部分导致了这次崩溃的线索......

有时它甚至不告诉任何行号，我真的不明白这种 Debug模式是如何工作的。我用过application verifier，它有时会给出一些行号。它看起来像是随机告诉我这些事情...我该如何解决这个问题？

这是我得到的:

MSVC 调试器非常强大。你付出的代价也是复杂的。

您可以告诉调试器中断任何未处理的异常。这是默认关闭的。在你的情况下，你想打破第一次机会的异常(exception)。这样做:

转到调试>异常...在出现的对话框中，选中“C++ 异常”和“Win32 异常”旁边的框。

运行你的程序。当这些异常发生时它应该中断。

请记住，第一次机会异常在 MFC 中广泛用于组件之间的通信。这些不是错误。但是您会在输出窗口中看到它们的报告。如果它们未得到处理，那就是您必须解决的问题。
