:cool:HI ALL:cool: I want that every memory allocation will be tracked... is there a way for me to overwrite the
newanddeletefunctions... this and every other solution will be appreciated gracefully. Objective:Tracking Memory AllocationsThank you all... :rose: -==--==--==--==--==--==- =--=The Server=--= -==--==--==--==--==--==-The C Runtime library provides memory tracking capabilities. See: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsdebug/html/_core_solving_buffer_overwrites_and_memory_leaks.asp[^] If you just want to find memory leaks that should do the trick. See my reply to Vikram re/ overloading new/delete.

Also, after overloading, you can still call the global new by ::new() Pankaj Without struggle, there is no progress

newcan be overloaded and so candelete.In fact, I guess even calls likeint *p=new int[10];
and
foo *ptr=new foo;
can be considered overloading, right? I wasn't drinking. I feel so dumb :-O ...I wonder if learning VB is any fun?

Yes, I made a mistake :-O . I don't even know what I confused it with. See my earlier post. Thanx for pointing it out.

I thought this warranted a second reply- new is an operator, isn't it? It calls a function alright, just like you have to define a function when you're overloading the
+operator for, say, aComplexclass. But that doesn't mean+becomes a function, even w.r.t. classComplex:~ And yeah, my 5 for pointing it out. :) Thanks,

1st of all: I want to thank all of you for your interest... 2nd: How can I overload the
newanddeletefunctions? :confused: Thank you all :rose:The Server:rose: -

Example, you can define something like: void * operator new (size_t size, char * fileName); void operator delete (void * p, char * fileName); Pankaj Without struggle, there is no progress

Dear Pankaj and every one that reads this messageThank you :rose: ... Only one question that which the most disturbing How do I call the Object's constructor(if is object?) =-=-=-=--=-=-=-=-= :rose: The Server =-=-=-=--=-=-=-=-=
