在 Windows Store app 环境下如何发现 C++ 内存泄漏

Question

在 win32 下可以用下面给的语句开启内存泄漏检测，程序退出时泄漏的信息会自动输出到开发环境的 output 窗口中。

_CrtSetDbgFlag( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );

可是在 Windows Store app 的环境下这个方法无效了，
那么在 Windows Store app 环境下有什么办法可以发现内存泄漏吗？

Answer 1

你好 慧鹏，

我对 CrtSetDbgFlag 不是很熟悉，不过在Windows Store App 里面一般常用检测内存泄漏的办法是：

我的VS版本是2012
在我的菜单上看到的东西与你的不一样。
我用 Start Performance Analysis 启动程序后，在结果中没有内存泄露报告。

Answer 3

内存检测貌似是VS2013自带的新工具。

在VS2012里面需要用其他工具， 比如： http://blogs.msdn.com/b/webapps/archive/2012/11/23/troubleshooting-memory-leaks-in-windows-store-apps.aspx

Answer 4

NP 工具里也看不到 C++ 的内存泄露。

是不是 C++ 的内存泄露在 Windows Store 环境下本来就是无法定位的啊？

Answer 5

你好

C++程序在商店应用中包了一层CX的外壳，从原理上来说，C++/CX 也是可以被工具定位到的。

我建议你升级到VS2013版本，现在不是有一个VS2013 Community嘛，我正在用那个，免费的，而且功能强大，VS2013 也是可以写VS2012 的代码，同时用VS2013的话将会有一些新的API可以使用啦。

Answer 6

我没换VS2013主要是因为对应的VA没有找到。
有人知道下载VS2013对应的VA的地址吗？

Answer 7

你指的是 Visual Assist嘛？这个我不清楚，不过貌似VS2013里面集成了很多新功能，有些可以替代VA，同时Bing有一个VSX的助手貌似也不错。

关于VS相关的问题，我建议你可以去对应的VS论坛发讨论帖吧。
