Hi,

I am trying to replace the new and delete functions in my MFC derived C++
application - the reason is to find memory leaks - but I keep getting a
linker error saying that 'new' is already declared in mfc80.dll.

I obviously have to link with mfc80.dll, but how do I replace the new
function?!?

I'm using MS Visual Studio Team Edition 2005. And it's a MFC C++
application.

Thanks in advance. !!!

I'm placing the following code in the stdafx.h file:

#ifdef _DEBUG
   inline void * __cdecl operator new(unsigned int size, const char *file,
int line)
   {
       void *result = (void *)malloc(size);
       if( !result )
       {
           throw_bad_alloc();
       }

       AddTrack((DWORD)result, size, file, line); // my memory trace
function

       return( result );

   };

   //
   // commented out for now !!
   //
   //inline void __cdecl operator delete(void *p)
   //{
   // RemoveTrack((DWORD)p);
   // free(p);
   //};

#endif // _DEBUG

#ifdef _DEBUG
#define DEBUG_NEW new(__FILE__, __LINE__)
#else
#define DEBUG_NEW new
#endif

#define new DEBUG_NEW
