Actually it is his real name.

I can't say it for sure. But I've seen several such new members with their name as their member number while making their first few posts. So, that's my guess.

Hi
I have created a network based video streaming application. Now i want to generate the documentation as well as the flow diagrams and uml diagrams for that project. Can someone suggest me a free nice tool which can do this??

You can use doxygen[^] for that part. But of course you still have to write the documentation yourself (in the source files). But it generates nice html output files which are really great to document classes and functions.

I have a list (CList) of pointers. Some of them point to variables in the heap a some others not.
I've defined a destructor that frees the memory space, but the program crashes when I delete a pointer to a variable in the stack.
The question is, is there any way of detecting if a pointer points to a variable in the stack or in the heap??
CMyList::~CMyList()
{
POSITION pos = GetHeadPosition();
while (pos != NULL)
{
if (GetNext(pos) points to the heap)
delete GetAt(pos);
}
RemoveAll();
}

I think its possible to find. Normally the stack size will be 1 MB, so a pointer to an object pointing to stack will have the value between the Stack top - 1MB to Stack top. All other pointer will be pointing to heap. You can get the stack top from the TIB as follows.
DWORD dwStackTop = 0;
__asm
{
mov EAX, FS:[4]
mov dwStackTop, eax
}

This is not an answer to your question but it looks that there's a little problem with how you designed your app. Why do you need to mix pointers from the heap with pointers from the stack in the same list ?
Which kind of objects does your list contain ? How do you insert new elements in the list ? Can you provide some code ?

In my application, in theory the list should be filled with pointers to the heap. I understand that it is not good practice to mix pointers. However, I am developing it at the moment and making it crash very often, as I am making tests and so on. I was just wondering if there is an easy way of detecting this, so I stop crashing the program and showing an error message instead.
That is, it's not that I want to mix pointers in the same list, but I want to make sure that I am not doing it by mistake and find out only when the program crashes.

Probably avoiding pointer mixing will be a good starting point to prevent crashes.

The problem you describe could also be seen as a design problem, not an implementation problem.
Instead of the list taking care of destruction (and therefore passing ownership sometimes but not always), let the list elements take care of destruction and clean up them selfs. You could populate the list with a smart pointer that knows what to do, i.e. boost shared pointer[^]. So when you remove one (or many) entries the destructor of the shared pointer will take care of clean up, e.g. call delete for elements created on the heap.
However, generally I would not mix heap and stack and rather create all elements dynamically. Just saves you a lot of trouble and ownership will be crystal clear.

If I remember my history correctly, a certain bit is set on all dynamically allocated memory? I believe that dynamic allocation maps into your address space at a certain starting address, and you can see if you are above that address.
I am pretty certain that there is a bit that is set for all addresses used for heap allocations.
But as others have said, there is some other problem in how your list is designed or being used.
Peace!

I would like to know more about this bit settings. Can give some more explanation or give me some like that explains this...
Thanks
