Stop keyboard buttons on specific usb removal

ilstarno · November 3, 2015

Am using ahk to map keyboard buttons on space button.

For now i have two exe's . One is made in autoit and the other with autohotkey.

The autoit part is to recognize specified usb and close the ahk exe proces to activate keys wheen specific usb's are plugged. Wheen usb is removed it runs the ahk exe to map specific keys on keyboard.

But this is very slow and i need something more faster.

Can i map keyboard buttons once usb is removed and unmap those if usb is plugged

Bert · November 3, 2015

Is there any reason this can't all be done in AutoIt? If you can do it in AHK, it can be done in AutoIt. My thinking is instead of killing a process, just have the process know when the USB drive is inserted and act accordingly.

JohnOne · November 3, 2015

That is what the OP is asking.

ilstarno · November 3, 2015

Practically i want to enable keyboard buttons wheen specific usb is plugged in and disable those or map to another key on the keyboard only with autoit using a single process and be fast. But the real question is how?

JohnOne · November 3, 2015

I think the only way you map keys with AutoIt is With HotkeySet.

Posting your AHK code with help with a better answer.

ViciousXUSMC · November 3, 2015

The WMI method posted at the bottom of this works well for me. That should get you 99% of the way there really.

Was a good find for me too, trying to learn how to integrate wmi/com stuff with AutoIT more as thats about where I am at now with learning/skill.

the code i use for now is this one.

and the ahk key is

f1::space
f2::space
alt:space

i wanna be able to do that ahk stuff inside autoit without launching that ahk exe on usb removal and on usb insertion

yeah but i want to detect specified usb's not any usb wich enters on pc. i think to do this via VID/PID

ViciousXUSMC · November 3, 2015

If you look at that there are multiple ways to specify, he is using the "name" of the device.

You can find the VID/PID in Win32_PNPEntity and I am sure you can cross reference this list to the one in the script.

ilstarno · November 3, 2015

am using the VID/PID for this case and not the usb name.

yeah. but how can i stop the hotkeyset on usb plugged

Edited November 3, 2015 by ilstarno

ViciousXUSMC · November 3, 2015

If $USBPlugged
 HotKeySet("Key", "Function")
 Else
 HotKeySet("Key")
 EndIf

However you script it, the idea is just call HotKeySet again without giving a function.

Edited November 3, 2015 by ViciousXUSMC

ilstarno · November 3, 2015

can this be used?

HotKeySet("{F1}", "{SPACE}")

JohnOne · November 3, 2015

No, because a function cannot be called {SPACE}, "{" is an illegal character.

Re-read the help file for HotkeySet.

Edited November 3, 2015 by JohnOne

ilstarno · November 3, 2015

any direct help on the script i posted?

i mean the F1 key to remains blocked or maped to space until usb plugs in

Edited November 3, 2015 by ilstarno

ilstarno · November 3, 2015

#include <Misc.au3>
HotKeySet("{F1}", "_s")
While 1
Sleep(10)
WEnd
Func _s()
If _IsPressed('F1')=1 Then Send("{SPACE}")
EndFunc

I HOPE THIS HELPS, ANY CORRECTION?

Edited November 3, 2015 by ilstarno

GordonFreeman · November 3, 2015

HotKeySet("{F1}","_SPACE")

While 1

Sleep(30)

WEnd


Func _SPACE()

Send("{SPACE}")

EndFunc; _SPACE

HotKeySet and _IsPressed are two diferent things;

Hotkeyset interrups scrips and execute the specified function

_IsPressed you get the state of the key, true = is pressed, false = is not pressed, then you need verify in a loop the state of the key to do something

And also, _isPressed need include Misc, hotkeyset not need any include

;Something like?:

HotKeySet("{F1}")

Calling without any function you "unset" the hotkey
