You can't - there no ability to customize the Adobe Reader toolbars and there's no way you can tell if the person viewing the file is even using Adobe Reader.
You can set the document "initial view" to request that all the toolbars and menus are hidden, but it's only a request - the user can set their preferences to ignore it, and most non-Adobe software won't take any notice.
Tanks a lot!
How Can I the document "initial view" modify? Tanks!
