Tweaked some stuff to try and debug what is going on with PS/2 devices.
I altered the GetDeviceList() function to return all devices, even those without a VID and PID
This should make *something* appear in the monitor script for PS/2 devices
Furthermore I added a "Handle" parameter, so we can see the raw device handles
Attached a zip with the changed files

Thank You. It works now.
How can I remap up key?

@malcev I see no issue with subscribing to up and down, but I do see an issue with SendKeyEvent and ScanCodes > 256

Test script (Should remap Up to Down and vice versa):

Code: Select all

#SingleInstance force
#Persistent
#include Lib\AutoHotInterception.ahk

AHI := new AutoHotInterception()

;~ keyboardId := AHI.GetKeyboardId(0x04F2, 0x0112)
keyboardId := AHI.GetKeyboardId(0x413C, 0x2107)
AHI.SubscribeKey(keyboardId, GetKeySC("Up"), true, Func("KeyEvent").Bind(GetKeySC("Down")))
AHI.SubscribeKey(keyboardId, GetKeySC("Down"), true, Func("KeyEvent").Bind(GetKeySC("Up")))
return

KeyEvent(code, state){
	global AHI, keyboardId
	AHI.SendKeyEvent(keyboardId, code, state)
	ToolTip % "State: " state
}

^Esc::
	ExitApp

The way Interception represents right variants of keys (eg Right ALT etc) means that if SC is > 256, I do some custom logic.
This seems to not work for arrow keys

Attached is a replacement DLL which should let you send arrow keys, but I am not sure how to deal with this going forwards.
I have raised an Issue on GitHub regarding this

How can I use keyboardId := AHI.GetKeyboardId(0x413C, 0x2107) with handle only?

How can I use keyboardId := AHI.GetKeyboardId(0x413C, 0x2107) with handle only?
You can't at the moment, which is what I intend to rectify.
For the time being, you can just pass the interception ID instead.
eg

Code: Select all

keyboardId := 1
AHI.SubscribeKey(keyboardId, GetKeySC("Up"), true, Func("KeyEvent").Bind(GetKeySC("Down")))

Attached is a test of a new version that should let you get device ID from handle
Added methods:
GetKeyboardIdFromHandle(handle, instance := 1)
GetMouseIDFromHandle(handle, instance := 1)

Please test it all works for you, and I will push out a new release
I am guessing AHI.GetKeyboardIdFromHandle("ACPI\PNP0303") should work for you

I think here is error:

Code: Select all

	GetKeyboardIdFromHandle(handle, instance := 1){
		return this.GetDeviceId(false, handle, instance)
	}
	
	GetMouseIDFromHandle(handle, instance := 1){
		return this.GetDeviceId(true, handle, instance)
	}
It should be:

Code: Select all

	GetKeyboardIdFromHandle(handle, instance := 1){
		return this.GetDeviceIdFromHandle(false, handle, instance)
	}
	
	GetMouseIDFromHandle(handle, instance := 1){
		return this.GetDeviceIdFromHandle(true, handle, instance)
	}
And if I use this code

Code: Select all

#SingleInstance force
#Persistent
#include Lib\AutoHotInterception.ahk
AHI := new AutoHotInterception()
keyboardId := 1
AHI.SubscribeKey(keyboardId, GetKeySC("Up"), true, Func("KeyEvent").Bind(GetKeySC("Down")))
AHI.SubscribeKey(keyboardId, GetKeySC("Down"), true, Func("KeyEvent").Bind(GetKeySC("Up")))
return

KeyEvent(code, state){
	global AHI, keyboardId
	AHI.SendKeyEvent(keyboardId, code, state)
	ToolTip % "State: " state
}
then "up" remaps to "P" and down remaps to "H".

Good catch on the first one

Regarding the up/down not mapping again - that did not make it into this commit. The version I posted for you before was a bodge just to make sure I identified what the issue was.
I will be looking into a proper fix for that one ASAP
Attached is a DLL with these new changes, and the Up/Down bodge

AHA! I took another look at the code that deals with ScanCode > 255, and it was broken for all of them, not just up.

Old code:

Code: Select all

        public void SendKeyEvent(int id, ushort code, int state)
        {
            var stroke = new ManagedWrapper.Stroke();
            if (code > 255)
            {
                code -= 256;
                state += 2;
            }
            stroke.key.code = code;
            stroke.key.state = (ushort)(1 - state);
            ManagedWrapper.Send(_deviceContext, id, ref stroke, 1);
        }
DUH!! Interception uses 0 for press, 1 for release, or +2 to each of those if extended.
The above logic clearly only works properly when ScanCodes are < 256
It should do 1-state, and THEN add 2 if needed

New code:

Code: Select all

        public void SendKeyEvent(int id, ushort code, int state)
        {
            IsValidDeviceId(false, id);
            var st = 1 - state;
            var stroke = new ManagedWrapper.Stroke();
            if (code > 255)
            {
                code -= 256;
                st += 2;
            }
            stroke.key.code = code;
            stroke.key.state = (ushort)st;
            ManagedWrapper.Send(_deviceContext, id, ref stroke, 1);
        }

Code: Select all

MonitorWrapper := new AutoHotInterception("Monitor")
Monitor := MonitorWrapper.Instance
Monitor.Subscribe(Func("KeyboardEvent"), Func("MouseEvent"))
And then how to unload an object MonitorWrapper, and unsubscribe?

Adds support for Horizontal Wheel on Mice

Code: Select all

AHI.Instance.SendMouseButtonEvent(12, 6, 1)
I tried it but nothing happens, should the mouse physically support it?

I now understand it is necessary to use to unsubscribe

Code: Select all

Monitor.SetDeviceFilterState(dev.id, 0)
But is it necessary to destroy the Monitor and MonitorWrapper objects?
And where to read about SetDeviceFilterState and the rest?

Fix for SendKeyEvent when using ScanCodes > 255
It is impossible to send Numlock - sc145.
Although it sends sc145 but at the same time vkFF is not vk90.
But if to send sc45 then it is defined as Numlock, although sc45 is Pause.

The Monitor was never designed to be loaded / unloaded dynamically
SubscribeKey too it is impossible to unloaded ?

It seems to me that in such a topic it is necessary to unload all methods, including the instance itself.
