if i have a template class, defined basically like this:

  
// please just assume everything is perfect and correct.

template< class T >
class List {
....
};

and lets say that I want to use this class List to hold an "array" of Object''s i tried this, it didnt work

  
List< Object* > list;

Considering that something isn''t working, this isn''t a very safe assumption.

Agreed. However, I may be able to elaborate on it.

I remember having a similar issue a while back, when trying to use a std::list<T> in a class T. The compiler complained about something (sorry, I cannot recall, and no time to test it now). I got around it by using std::list<T *> instead. And here I realize that my problem wasn''t the same as OP''s one

They may, however, be related, why I post this anyway to get an excuse to bookmark it.

Feel free to waste your time speculating on what the OP''s problem might or might not be. I''d rather not.

My apologies everyone.
I was quite sleepy last night but knew i had to post this in one form or another before i could attempt to even sleep.

But, thanks for the direction(s)....CWizard.
But doing what you suggested would make my template class less flexible.

Perhaps I should simply declare my use for the template class as
:

  
List< Object > list;
// instead of List< Object* > list;
