[solved]_Dllcall read value

[goldenix]

I want to retrive this value: $lciPower_On . It shows whether the monitor is on or off.

Global  $lciWM_SYSCommand
Global  $lciSC_MonitorPower
Global  $lciPower_On

Global $Progman_hwnd = WinGetHandle('[CLASS:Progman]')

    DllCall('user32.dll', 'int', 'ReadMessage', _
            'hwnd', $Progman_hwnd, _
            'int', $lciWM_SYSCommand, _
            'int', $lciSC_MonitorPower, _
            'int', $lciPower_On)

ConsoleWrite($lciPower_On & @CRLF)

EDIT This is not solvable.:

I don't think there is a reliable way to do this, AutoIt or not. I've searched all over.

There is a function called GetDevicePowerState in Kernel32.dll, but it says "This function cannot be used to query the power state of a display device.":

I don't see ReadMessage anywhere on MSDN for user32.dll.

Or is that just me?

I do not know what will happen if I will change the readmessage to sendmessage maybe it will erase all previous data. Im scared.

So it is not possible to retrive $lciPower_On state? really?

What are you talking about ? There is no such export in user32.dll ! Where did you see this ReadMessage ?

ReadMessage -I thought if there is a sendmessage, maybe there is also a readmessage.

I want to know if my monitor is turned on or off.

I dont think this code is any use at all, no mater whether the monitor is turned on or off it always outputs following message:

Plug and Play Monitor
Moniter Name = Plug and Play Monitor
Moniter State = 3
Moniter State Meaning: 
    - Running or Full Power
Plug and Play Monitor
Default Monitor
Moniter Name = Default Monitor
Moniter State = 8
Moniter State Meaning: 
    - Running or Full Power
    - Off Line

PS: I don't think there is a reliable way to do this, AutoIt or not. I've searched all over. is what one of the MVP said.

Stupid windows....

How can windows detect if the monitor is turned on or off ?

Next, you'll make a thread about detecting if the speakers are turned on and on which volume.

This is MADNESS !!! lol

You can turn on & off monitor with short autoit dllcall, then it would be natural to assume, that there is a way to check if monitor is on or off. But it seems, it is not possible.
