非MFC程序可以用以下方法检测内存泄露：

1.程序开始包含如下定义：

view plaincopy to clipboardprint?

1. #ifdef _DEBUG

2. #define DEBUG_CLIENTBLOCK new( _CLIENT_BLOCK, __FILE__, __LINE__)

3. #else

4. #define DEBUG_CLIENTBLOCK

5. #endif // _DEBUG

6. #define _CRTDBG_MAP_ALLOC

7. #include

8. #include

9. #ifdef _DEBUG

10. #define new DEBUG_CLIENTBLOCK

11. #endif // _DEBUG

2.程序中添加下面的函数：

view plaincopy to clipboardprint?

1. _CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF|_CRTDBG_LEAK_CHECK_DF);

1. #ifdef _DEBUG

2. protected:

3. CMemoryState m_msOld, m_msNew, m_msDiff;

4. #endif // _DEBUG

1. #ifdef _DEBUG

2. m_msOld.Checkpoint();

3. #endif // _DEBUG

4.

5.

3.在 CMyApp::ExitInstance() 中添加如下代码：

view plaincopy to clipboardprint?

1. #ifdef _DEBUG

2. m_msNew.Checkpoint();

3. if (m_msDiff.Difference(m_msOld, m_msNew))

4. {

5. afxDump<<"/nMemory Leaked :/n";

6. m_msDiff.DumpStatistics();

7. afxDump<<"Dump Complete !/n/n";

8. }

9. #endif // _DEBUG

0 bytes in 0 Client Blocks.

Largest number used: 8825 bytes.

Total allocations: 47506 bytes.

Dump Complete !

Detected memory leaks!

Dumping objects ->

g:/programs/chat/chatdlg.cpp(120) : {118} normal block at 0x00D98150, 8 bytes long. Data: < > A8 7F D9 00 01 00 00 00

Object dump complete.
