Are there any way to check the memory leak in VC ? such as memory log ? |

哪里找到免费版？？
我记得VC 里有个设置可以看 ＭＥＭＯＲＹ ＰＲＯＦＩＬＥ的？不知怎么弄？
谢谢

时就记下了。给你作个参考，呵呵
//This is how to debug memory leak.
//Add #define _CRTDBG_MAP_ALLOC #include #include
//at the beginning and add the following statement in the program.
//Then run debug (F5)
//System will return where memory leaks, a number within {}
//Then at very beginning of the program, set a breakpoint, run debug.
//When program stops at the breakpoint, in watch window, set the value
//of function _crtBreakAlloc to that num |

发帖数: 44 | 7 why my break point is at dbgheap.c file not my own program file ?
How can I find which function in my program caused the problem ?
Many thanks.
the memory leak dump info is:
Dumping objects ->
{82} normal block at 0x02E61188, 28 bytes long.
Data: 6C 5A 50 00 38 56 7A 02 48 20 7A 02 A0 20 7A 02
Object dump complete.
I include "#define _CRTDBG_MAP_ALLOC " already in the program.

Did you use _malloc_dbg?
As I remember, when you create a MFC project in VC6, all the necessary
codes for detecting memory leaks are generated. You can learn from them.

发帖数: 44 | 9 This is not MFC related. I just used VC as a editor,compiler and debugger.
which file stores such info ?

发帖数: 1252 | 10 What I said is that you can learn from MFC on how to use those CrtXXX
functions.
Otherwise just google _malloc_dbg and look into the last two parameters.
You have to override new/malloc someway to add file/line info.
