MFC关于VS内存释放的定位

全部在App中完成

1.在 App.h 头文件声明

#ifdef _DEBUG
protected:
      CMemoryState m_msOld, m_msNew, m_msDiff;
#endif  // _DEBUG

2.在 App::InitInstance() 中添加如下代码：

#ifdef _DEBUG
      m_msOld.Checkpoint();
#endif  // _DEBUG

3.在 App::ExitInstance() 中添加如下代码：

#ifdef _DEBUG
      m_msNew.Checkpoint();
      if (m_msDiff.Difference(m_msOld, m_msNew))
      {
            afxDump<<" Memory Leaked : ";
            m_msDiff.DumpStatistics();
            afxDump<<"Dump Complete ! ";
      }
#endif  // _DEBUG

Debug模式下运行，然后正常退出exe，

输出：（直接双击红色部分会定位到没有释放内存的地方）

-2431 bytes in -80 Normal Blocks.
0 bytes in 0 CRT Blocks.
