Hello

Thank yoU!

You can check here and also this might help also... You would have to use dllcall to use these functions

After some digging about GetDevicePowerState I found a little code in the old forums about it:

Code: Select all

hDisp := DllCall("CreateFile","Str","\\.\LCD","Uint",0xC0000000,"Uint",0x3,"Uint",0,"Uint",0x3,"Uint",0,"Uint",0)

DllCall("GetDevicePowerState", "UInt", hDisp, "IntP", stat)

Always returns 0, I guess I have to change the "\\.\LCD" value to match the ID of monitor? I don't know what to put in there.

About the last link you posted I have to compile it with visual studio?

Thanks!
