pass a listview object to a dll

Is it possible to pass a list view object to a dll?? as of right now it won't let me because if i declare the function as public.. it says that i can't use a private object module as a parameter for a public function...

the reason i am doing this is because i have about 9 apps here at work and they share a dll that has a lot of common functions.. and one of the functions i would like to put in is a listview sorting function.. but i don't want to include it in every app. i would rather put it in the dll to call..

You have to pass things like that from VB as Object. Object gets passed as a pointer to the Object, by default.
