code:
Open App.Path & "C:\Program Files\Multi-app\password.txt" For Input As #1

Why don't you re-read CookieRevised's post?
If you don't know a language you're never going to learn it by randomly copying/pasting code from other places hoping it'll work, and then asking other people to fix your code without an explanation of what was wrong. Buy a book. Follow some tutorials. Learn.
