You can iterate through the list and remove duplicate ones no? Also there are useful

Why don't you check before inserting? :)

you can traverse thorough the list to see if the element you are going toinsert already exist or not. if it exsist dont insert. otherwise insert.

You can use unique only if you have a std::list/vector/etc with you which instead you are inserting to a list control. But since you are directly inserting to the list control use CListCtrl::FindItem, if found don't insert. I guess this will help?
