After you develop custom sAPOs, you must implement a user interface to configure the various system effects features that you have provided. The default Windows Vista user interface for system effects is implemented as a property page on a property sheet.
A property sheet is a window that allows the user to view and edit the properties of an item. A property sheet contains one or more overlapping child windows called property pages, each containing control windows for setting a group of related properties. Each page has a tab that the user can select to bring the page to the foreground of the property sheet.
You have the following two options for implementing your user interface.
If you wrap the system-supplied sAPOs with your custom sAPOs you will not be able to configure your custom features using the Windows Vista property page. In order to provide a way to configure your custom features, you have to replace the Windows Vista default property page. See the Replacing the Default Property Page topic for information about how to do this.
If you replace the system-supplied sAPOs with ones that you developed, you must provide a separate UI for configuring your sAPOs. See the Custom UI Design Information topic for details about how to do this.
