問題與MFC診斷

所以我放棄了實施我自己的memoryleak跟蹤（在這個問題overloading new and delete）並嘗試使用MFC函數來識別我的內存泄漏。所以我做的正是在這裏描述：問題與MFC診斷

http://msdn.microsoft.com/en-us/library/8ky2wh64(VS.80).aspx

這是我的代碼：

#ifdef _DEBUG 
    CMemoryState oldMemState, newMemState, diffMemState; 
    oldMemState.Checkpoint(); 
#endif 

    int* test = new int; 

#ifdef _DEBUG 
    newMemState.Checkpoint(); 
    if(diffMemState.Difference(oldMemState, newMemState)) 
    { 
     TRACE("Memory leaked!\n"); 
     diffMemState.DumpStatistics(); 
     diffMemState.DumpAllObjectsSince(); 
    } 
#endif

不輸出任何有用的信息，但是，輸出顯示

     4 bytes in 1 Normal Blocks.

.. .......並且這是正在進行和正在進行，括號內的數字正在倒計時（我實際上從來沒有耐心等待讓它倒數1）

它總是從這個高數714538 所以 - 我做錯了什麼？

謝謝！

我認爲，大量的是行號。 – Synetech 2009-12-06 20:14:43

不，根據文檔「大多數行開頭的大括號中的數字指定了對象的分配順序，最近分配的對象具有最高數字，並且出現在轉儲的頂部。但在兩個檢查點之間只有一個int分配在堆上，所以這麼高的數字沒有意義 – Mat 2009-12-06 21:18:31

從here它顯示DumpAllObjectsSince（）應該在您調用Checkpoint（）的CMemoryState對象上調用。

所以，你的代碼應該是：

{ 
      TRACE("Memory leaked!\n"); 
      diffMemState.DumpStatistics(); 
      //diffMemState.DumpAllObjectsSince(); 
      oldMemState.DumpAllObjectsSince(); 
    }

嘿嘿就是這樣:)非常感謝你！ – Mat 2009-12-06 22:05:02
