Screen savers

[Guest]

Hi,

Is there an event I can listen for in WndProc so I know when the screen
saver is active and insactive?

Thanks

Thats when it starts, is that event fired when it stops also?

If so, how do we know its started or stopped? Nothing in LParam?

I don't believe there's an equivalent for the screen saver being stopped.
However you can use start a timer in your application and call
SystemParametersInfo() with uiAction set to SPI_GETSCREENSAVERRUNNING.
