Thanks OP, this was just what I was looking for! I combined your script along with this
so that the caps lock indicator LED turns on when the mic is muted (can be done with scroll lock or numlock as well). Here's the script in case anyone is interested:
Code: Select all
Capslock::
SoundSet, +1, MASTER, mute, 5 ;5 is my mic ID number, must use a separate script to figure out your mic ID. then replace the 5 in this line and the line below it with your mic ID
SoundGet, master_mute, , mute, 5
if (master_mute = "On") {
Loop, 12 {
KeyboardLED(4, "On", A_Index-1)
}
} else {
Loop, 12 {
KeyboardLED(4, "Off", A_Index-1)
}
}
KeyboardLED(LEDvalue, Cmd, Kbd=0)
{
SetUnicodeStr(fn,"\Device\KeyBoardClass" Kbd)
h_device:=NtCreateFile(fn,0+0x00000100+0x00000080+0x00100000,1,1,0x00000040+0x00000020,0)
If Cmd= switch ;switches every LED according to LEDvalue
KeyLED:= LEDvalue
If Cmd= on ;forces all choosen LED's to ON (LEDvalue= 0 ->LED's according to keystate)
KeyLED:= LEDvalue | (GetKeyState("ScrollLock", "T") + 2*GetKeyState("NumLock", "T") + 4*GetKeyState("CapsLock", "T"))
If Cmd= off ;forces all choosen LED's to OFF (LEDvalue= 0 ->LED's according to keystate)
{
LEDvalue:= LEDvalue ^ 7
KeyLED:= LEDvalue & (GetKeyState("ScrollLock", "T") + 2*GetKeyState("NumLock", "T") + 4*GetKeyState("CapsLock", "T"))
}
success := DllCall( "DeviceIoControl"
, "ptr", h_device
, "uint", CTL_CODE( 0x0000000b ; FILE_DEVICE_KEYBOARD
, 2
, 0 ; METHOD_BUFFERED
, 0 ) ; FILE_ANY_ACCESS
, "int*", KeyLED << 16
, "uint", 4
, "ptr", 0
, "uint", 0
, "ptr*", output_actual
, "ptr", 0 )
NtCloseFile(h_device)
return success
}
CTL_CODE( p_device_type, p_function, p_method, p_access )
{
Return, ( p_device_type << 16 ) | ( p_access << 14 ) | ( p_function << 2 ) | p_method
}
NtCreateFile(ByRef wfilename,desiredaccess,sharemode,createdist,flags,fattribs)
{
VarSetCapacity(objattrib,6*A_PtrSize,0)
VarSetCapacity(io,2*A_PtrSize,0)
VarSetCapacity(pus,2*A_PtrSize)
DllCall("ntdll\RtlInitUnicodeString","ptr",&pus,"ptr",&wfilename)
NumPut(6*A_PtrSize,objattrib,0)
NumPut(&pus,objattrib,2*A_PtrSize)
status:=DllCall("ntdll\ZwCreateFile","ptr*",fh,"UInt",desiredaccess,"ptr",&objattrib
,"ptr",&io,"ptr",0,"UInt",fattribs,"UInt",sharemode,"UInt",createdist
,"UInt",flags,"ptr",0,"UInt",0, "UInt")
return % fh
}
NtCloseFile(handle)
{
return DllCall("ntdll\ZwClose","ptr",handle)
}
SetUnicodeStr(ByRef out, str_)
{
VarSetCapacity(out,2*StrPut(str_,"utf-16"))
StrPut(str_,&out,"utf-16")
}
The loop is included because sometimes on reboot the keyboard index number changes so this ensures it works even if that happens. I converted the script to an .exe and added the shortcut as a startup program so that it runs on boot. It seems to run well but I have limited experience with AHK so let me know if there are any improvements to be made. Hopefully this is useful for someone!
