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! I made a horrifying mistake. Both new and delete can be overloaded. See all posts below.[/EDIT]

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.

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?

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.

Hi,
Both new and delete can be overloaded. Also, after overloading, you can still call the global new by ::new()

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

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);

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!!!

The easiest way is to precede the class in the file with an enumerator that indicates what sort of object follows.
|
|
|
|
|
Why don't you put all your objects in a CObArray and use the CObArray::Serialize to read and write?

Hi friends,
Anybody have an idea how to get the details of the clients, workstation in a network ???
I thought it will be possible with NetBIOS. Is there any API for using that ??
Any suggestion regarding this will be very useful for my project.
Thanks & Regards
Satya

These should get you started:
WNetOpenEnum()<br />
WNetEnumResource()<br />
NetWkstaGetInfo()<br />
NetWkstaUserGetInfo()<br />
NetWkstaUserEnum()

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.
Thanks,
Steve

Oops, sorry, I didn't see it was written in C# when I looked at it...maybe I'll give a shot at porting it to MFC sometime.
