Hi All,

i have one win32 exe and after executing it, in the task manager the memory usage is increasing even there is nothing to process for exe.At the starting its size is 150kb but it is increasing up to 10 mb. so please can anyone tell me the possible reasons and solutions.

Thanks A Ton

you have memory leak.

check your program that every new function match a delete function.

remember to release every resource you have got.

hi,
i checked new/delete sequence there is all fine, is there anything else which can cause memory leak or how can i detect memory leak...

Thanks A Ton

You have got tools to detect whether you have a memory leak. Search for BoundsChecker or Rationals Purify plus.

You need to google first, if you have "It's urgent please" mentioned in your question.

Hi Anshuman,

i serched for both the tool and i think purifyplus is free downlable but i dont know how to use it so can you please tell me which tool ishould use(depending its a freeware) and where i can get details of using the tool as i didnt got anything on it after googling.... Confused | :confused:

Thanks A Ton

Does your debugger report memory leaks in the output window after your binary finishes execution (in debug mode)?

Hi,

these add up to a few KB at most, and won't explain what you are seeing. So there probably is no memory leak.

Are you allocating some large data structures, say an array of several MB, even when there isn't any reason to already allocate such?

Smile | :)

There are probably source files where new isn't redefined to DEBUG_NEW (probably you added some C/C++ files yourself?). Try to add this definition to all the source files where it isn't present:

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

This will enable the debugger to display the exact line numbers in your program where there were memory allocations (that weren't cleaned up).

Leaks at strcore.cpp most likely means that you are misusing strings in your program (improper shutdown/termination of a thread that was using strings?). That becomes too much of a big topic to discuss in a reply.

If your codes is not very long,put it out. We can find the problem for you. I think that must be a memory leak.

I have a little confused by how to calculate the duration of AAC audio,i read the ISO/IEC 13818-7,but find no answer,now i don't know where to find the formula to calculate the duration.
I can get the sample rate(ADTS) or bit rate(ADIF),maybe it's no use of calcalating the duration,who can help me?thanks.
I'm sorry for my poor english.

Actually i hv to update a mesh that i m creating .I m getting all that information in header file and i hv to include that file .But every time i cant include it manually na?Thats y i need it.

Psuedocode:

fn(){

// creating a header file with name sample.h
________
_______
___

#include"sample.h"

}
so inspite of giving it manually I want at run time.

If you don't want to rebuild every time the header file changes, you're going to have to add code to read that file at run-time and interpret and use the information in it.

That's probably about the easiest way to do it ~~without calling the C compiler from your program, compiling the header into some DLL or something and using that from your program~~. Yeah, that's definitely the easiest way to do it.

You can't do something like that without recompiling your program (which I guess you don't want to do). What you will need to do is instead load your data from a file and store it in a structure in memory.
