Screensaver Event?

[spazlon]

Hello,

I am trying to turn off my TV when the screensaver is activated and turn on the TV when the screensaver is deactivated.

I have the TV on/off functions working, but I can't find the event for the screensaver. What can I use to accomplish this?

Thank you,

Ryan

The "Task Create/Switch Events" plugin generates several events on my WinXP when the screensaver is activated.

If you are using still the same screen saver, you can use for your purpose the Application Observer plugin.
I just added there to observe not only the application type .exe, but also type .scr.
For example, the 3D Text screensaver you simply add to observe by adding the ssText3d.scr applications.

If you change screensaver sometimes, it's better to use this script:

Code: Select all

period = 2.0  #Test every 2 seconds

SPI_GETSCREENSAVERRUNNING  = 0x72
from ctypes import byref, c_bool
from ctypes.wintypes import WinDLL
saverRunning = c_bool()


def CheckScreensaverRunning():
    WinDLL("user32").SystemParametersInfoA(SPI_GETSCREENSAVERRUNNING, 0, byref(saverRunning), False)
    running  = saverRunning.value
    if running != eg.globals.ScreenSaverRunning:
        eg.globals.ScreenSaverRunning = running
        eg.TriggerEvent("ScreensaverRunning.%s" % str(running), prefix="System")
    eg.scheduler.AddTask(period, CheckScreensaverRunning)

eg.globals.ScreenSaverRunning = None
CheckScreensaverRunning()

The script should be placed into a macro that will be triggered after start by event Main.OnInit.

This didn't work for me because when the screensaver was activated the dekstop event would fire. This means if the screensaver came on, the TV would turn off, but also if I minimized MCE the TV would also turn off.

Code: Select all

period = 2.0  #Test every 2 seconds

SPI_GETSCREENSAVERRUNNING  = 0x72
from ctypes import byref, c_bool
from ctypes.wintypes import WinDLL
saverRunning = c_bool()


def CheckScreensaverRunning():
    WinDLL("user32").SystemParametersInfoA(SPI_GETSCREENSAVERRUNNING, 0, byref(saverRunning), False)
    running  = saverRunning.value
    if running != eg.globals.ScreenSaverRunning:
        eg.globals.ScreenSaverRunning = running
        eg.TriggerEvent("ScreensaverRunning.%s" % str(running), prefix="System")
    eg.scheduler.AddTask(period, CheckScreensaverRunning)

eg.globals.ScreenSaverRunning = None
CheckScreensaverRunning()

I will give this a try when I get home tonight. This looks like a solid solution. I see how it will fire an event when the screensaver is activated, but when the screensaver is deactivated will it fire another event?

Thanks for the quick replies guys!!

Of course yes.

Code: Select all

System.ScreensaverRunning.True
System.ScreensaverRunning.False

I got these events when the screensaver activated Task.Created.scrnsave, Task.NewWindow.scrnsave and Task.Activated.scrnsave.
And when the screensaver deactivated I got these events Task.Deactivated.scrnsave, Task.ClosedWindow.scrnsave and Task.Destroyed.scrnsave.

Don't you get those?

I get only this (timeout = 1 min; OS = Windows 7):

Code: Select all

13:49:36   System.Idle
13:49:57   Task.Deactivated.pn
13:49:57   Task.Activated.Desktop
13:52:02   System.UnIdle
13:52:02   Task.Deactivated.Desktop
13:52:02   Task.Activated.pn

Nope, I'm at work right now so I can't get the logs, but it was something like Application.Desktop when the screensaver was activated and Application.MediaCenter when the screensaver was deactivated.

I will play with it some more tonight when I get home.

Bah, you posted when I was composing that last post.

I'm pretty sure those are the same log events I get as well.

Pako, I will try your method tonight.

Thanks again guys!

Pako -

This ended up working perfectly. Thanks!

Now I just need to see if it will work while I am in Media Center. I don't remember the name of the screensaver it runs.

Thanks again!
