ACL Component

[Previous] [Next]

To provide you with the ability to query and modify access control lists (ACLs) on folders, Microsoft offers an ACL COM component. This component works in conjunction with the CDO library to allow you to change permissions on folders for which you are the owner. Before the ACL component was available, you had to either manually hack the hex properties on the folder or write a C/C++ program to manipulate folder permissions by using Extended Messaging Application Programming Interface (MAPI). The first of those solutions is not desirable since future versions of the product could break your code and make your code more error prone, and the second solution is hard to implement unless you know the C/C++ programming language. The Project sample application, which we're about to examine, uses the ACL component extensively, so you'll learn about it in context.
