FILE: ScreenSaverPg.cpp
|
|
|
|
DESCRIPTION:
|
|
This file contains the COM object implementation that will display the
|
|
ScreenSaver tab in the Display Control Panel.
|
|
|
|
18-Feb-94 (Tracy Sharpe) Added power management functionality.
|
|
Commented out several pieces of code that weren't being
|
|
used.
|
|
5/30/2000 (Bryan Starbuck) BryanSt: Turned into C++ and COM. Exposed
|
|
as an API so other tabs can communicate with it. This enables
|
|
the Plus! Theme page to modify the screen saver.
|
|
11/08/2000 (Bryan Starbuck) BryanSt: Moved from \nt\shell\cpls\desknt5 to
|
|
\nt\shell\themes\themeui\.
