Ppo3svrScr.cpp

Abstract:
|
||
|
|
|
||
|
|
Power Plus screensaver bundled with Lotus Super Office 2000 Japanese could not launch
|
||
|
|
Configure dialog on Whistler. But it works on Win 2000.
|
||
|
|
The desk.cpl behavior of launching screensaver is changed a bit on Whistler.
|
||
|
|
This screensaver's ScreenSaverConfigureDialog ID is not DLG_SCRNSAVECONFIGURE (2003=MSDN must) and unusual.
|
||
|
|
Assuming unusual screensaver.
|
||
|
|
This shim is applied to screensaver and hacks GetCommandLineW/A return text to change from
|
||
|
|
"D:\WINDOWS\System32\ppo3svr.scr /c:1769646"
|
||
|
|
to
|
||
|
|
"D:\WINDOWS\System32\ppo3svr.scr"
|
||
|
|
so that configure dialog appears.
|
||
|
|
|
||
|
|
More Info:
|
||
|
|
|
||
|
|
From desk.cpl (rundll32.exe), Screen Saver operation and CreateProcessW lpCommandLine argument:
|
||
|
|
(1) Initial selection of screensaver
|
||
|
|
"D:\WINDOWS\System32\ppo3svr.scr /p 721330" -> preview only
|
||
|
|
(2) Preview button
|
||
|
|
1st call "D:\WINDOWS\System32\ppo3svr.scr /s" -> screen saver
|
||
|
|
2nd call "D:\WINDOWS\System32\ppo3svr.scr /p 721330" -> return to preview
|
||
|
|
(3) Settings button
|
||
|
|
1st call "D:\WINDOWS\System32\ppo3svr.scr /c:1769646" -> configure dialog (not working)
|
||
|
|
2nd call "D:\WINDOWS\System32\ppo3svr.scr /p 721330" -> return to preview
