Does someone has knowledge with templates ?

[nickels]

yes.

Do a quick search on google or any other search engine, there are lots of info about it there.

hello, i've send you an email, but you seem not having replied.

I was just trying to be a funny guy (smart-aleck).

I do know a lot about templates and can offer answers, but I don't have time to jump aboard your project. Too busy climbing rocks and mountains!

[jide]

hello.

OK. you don't need to climb my project. i only wanted to know why my templates are not working as i want.

Well, you may have to be a little more descriptive. I know that I myself am not telepathic so I can't help much at the moment.

sorry for the late, but i haven't got the net at home.

I wanted to make generic template classes to avoid redundant implementation of linked list functionalities. My classes are hierarchic, from one mother class. I use polymorphism.

my template implementation is something like this:

template <class O> class list_object
{
O *next;
O *prev;

list_object( ...)
};

template <class O> class list: public list_object
{
// i don't remember here
void AddObject( O data);
void RemoveObject( O data);
};

All seems OK: compilation, linking ( i had errors while linking before, but i correct it). But while executing everything's going bad and worst !

maybe you'll need to see the code ?

[nickels]

Try:

template <class O> class list: public list_object<O>
{
void AddObject( O data);
void RemoveObject( O data);
}

list_object needs to have the template parameter specified.

first, thanks for your care.
(sorry if my english not very good)
But, that's not made any good change.
now, i have to implement the template methods
inner the class definition. that's a wrap !
Now it seems it couldn't create these objects, it seems it overwrite other memory emplacements.
I may go forward each time i try again, but i think i will never succeed.

I would like to know: templates seem to not work if there are preprocessor declaration inner the class. But if the preprocessor declaration is inner the class to match, is it not good too ?
thanks
