I'm assuming you meant to say overload , because new and delete are not functions; they are operators. In that case, no- these operators CANNOT be overloaded. [EDIT]Red alert! Red alert!

In that case, no- these operators CANNOT be overloaded. Vikram, I'm afraid you aren't right. The new operator calls a function to allocate memory and you can overload or rewrite that. There is also "placement new". Look up a good C++ reference for more info. "More Effectiver C++" covers this briefly. And there maybe articles here on CP about overloading new and delete if my memory serves me correctly. Neville Franks, Author of ED for Windows.

Yes, I'm afraid you're right. Punning apart, thanks for correcting me. Yes, new can be overloaded and so can delete.In fact, I guess even calls like int *p=new int[10]; and foo *ptr=new foo; can be considered overloading, right? I wasn't drinking. I feel so dumb ...I wonder if learning VB is any fun? Vikram. ----------------------------- My site due for a massive update 1. Don't ask unnecessary questions. You know what I mean? 2.

Re: Tracking Memory Allocations Vikram A Punathambekar19-May-03 1:08 Vikram A Punathambekar 19-May-03 1:08  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, a Complex class. But that doesn't mean + becomes a function, even w.r.t. class Complex And yeah, my 5 for pointing it out. Thanks, Vikram. ----------------------------- My site due for a massive update 1.

Re: Tracking Memory Allocations pankajdaga19-May-03 0:48 pankajdaga 19-May-03 0:48  Hi, Both new and delete can be overloaded. Also, after overloading, you can still call the global new by ::new() Pankaj Without struggle, there is no progress Re: Tracking Memory Allocations Vikram A Punathambekar19-May-03 0:57 Vikram A Punathambekar 19-May-03 0:57  Yes, I made a mistake . I don't even know what I confused it with. See my earlier post. Thanx for pointing it out. Vikram. ----------------------------- My site due for a massive update 1. Don't ask unnecessary questions.

Thank you all The Server Re: Tracking Memory Allocations pankajdaga21-May-03 0:57 pankajdaga 21-May-03 0:57  You an overload class specific new and delete as: void * operator new (size_t size) { // do your thing } void operator delete (void * mem) { if (mem) // do yout thing } You can also overload the global new and delete. 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 Re: Tracking Memory Allocations The_Server21-May-03 23:28 The_Server 21-May-03 23:28  Dear Pankaj and every one that reads this message Thank you ... Only one question that which the most disturbing How do I call the Object's constructor(if is object?) =-=-=-=--=-=-=-=-= The Server =-=-=-=--=-=-=-=-= Re: Tracking Memory Allocations Anonymous19-May-03 0:37 Anonymous 19-May-03 0:37  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.

Serializing multiple dynamic objects Frank Christensen18-May-03 23:27 Frank Christensen 18-May-03 23:27  Hi Im trying to figure out subject but I cant get it to work. I have no problem saving but when I want to load the data again I have to somehow know what type of object it is and then create it...how do I do that? Tnx in advance!!! Re: Serializing multiple dynamic objects Martyn Pearson19-May-03 0:17 Martyn Pearson 19-May-03 0:17  The easiest way is to precede the class in the file with an enumerator that indicates what sort of object follows. Re: Serializing multiple dynamic objects BadJerry19-May-03 1:45 BadJerry 19-May-03 1:45  Why don't you put all your objects in a CObArray and use the CObArray::Serialize to read and write?

WinXP like option tree Steve Messer18-May-03 22:32 Steve Messer 18-May-03 22:32  I am looking for info on how to mimic the option bar found in winxp's explorer. It is also used in the CD burning software Alcohol 120%. Sorry if I am not giving the correct name or describing it very well. I don't know what it is called. In explorer it has the options: system tasks, other places and details. They are collapsable. Well let me know.
