How do i make sure an app made in vb 6 will work on a vb 5 machine? I know there is some line you have to delete, but cant remember what it is. Also, if i use a vb6 control, such as the winsock, can i make it work on 5?

And another question-
How would i ass elements to a menu at runtime? Like the favorites, or a list of recently opened files, and whatnot?
