HotKeySet not working when default keyboard layout set as non-english

[MrCreatoR <mscreator@…>]

For users that have they default keyboard layout set to other language than english in the system, HotKeySet with english letters does not triggers the event function.

Reproducing example (default keyboard layout must be switched to other than english):

;Ctrl + Shift + D
HotKeySet("^+d", "TestFunc")

While 1
	Sleep(100)
WEnd

Func TestFunc()
	MsgBox(0, "TestFunc", "Executed, so default keyboard layout is English, please switch.")
EndFunc

And it is not a system bug as i see it, because here is a script that register a hotkey using «RegisterHotKey» API and «WM_HOTKEY» message:

$VK_D = 0x44

$MOD_ALT = 0x0001
$MOD_CONTROL = 0x0002
$MOD_SHIFT = 0x0004
$MOD_WIN = 0x0008

$hWnd = GUICreate('')
GUIRegisterMsg(0x0312, "MY_WM_HOTKEY") ; WM_HOTKEY

; Set CTRL-SHIT-D
DllCall('user32.dll', 'int', 'RegisterHotKey', 'hwnd', $hWnd, 'int', '0', 'uint', BitOR($MOD_CONTROL, $MOD_SHIFT), 'uint', $VK_D)

While 1
	Sleep(100)
WEnd

Func MY_WM_HOTKEY($hWnd, $Msg, $wParam, $lParam)
	MsgBox(0, 'MY_WM_HOTKEY', 'You pressed CTRL-SHIFT-D.')
	Exit
EndFunc

Tested on:

• Windows XP RU SP3 32
• Windows 7 Home RU 32

Not sure this is a bug. If I change the keyboard to Russian and then run:

; Looks like D is в on the Russian keyboard
HotKeySet("^+в", "TestFunc")

Then it works fine. But when the API tries resolve the key "d" on a Russian keyboard it fails, but I sort of expected that. I guess I could assume that if a key is in the ASCII range then to take the VK code literally, but I'm wondering if that would actually break more...

I have Italian keyboard layout set and it works.
It works even if I use "^+D" (D is uppercase). Try this because with shift, characters are uppercased.
But what do you mean as other language than english? Latin or Asiatic/Cyrillic languages? Maybe it's a problem with RU(ssian) systems or keyboards.

Tested on Windows Server 2008 Enterprise SP2 Italian 32-bit with AutoIt 3.3.4.0

[VittGam <vittgam@…>]

Sorry, I've made a mistake. It's Windows Server 2008 Enterprise SP2 English 32-bit with Italian MUI Language Pack, Italian keyboard layout as default and AutoIt v3.3.4.0.

Replying to Jon:

HotKeySet("^+в", "TestFunc")

It works fine (not everywhere thought, see next), but then we should check every time the keyboard layout:

Switch @KBLayout
	Case 0409
		HotKeySet("^+d", "TestFunc")
	Case 0419
		HotKeySet("^+в", "TestFunc")
EndSwitch

but even this is not working on my other system, where the base language is Hebrew, and no mater what default keyboard layout is set (russian or hebrew).

I mean non-latin, that is out of 1-127 characters range set. And no, it's not russian-specific issue :)

I cannot have acces to a russian or Hebrew window, but I want to be sure of the output on such system with the following script

;Ctrl + Shift + D
$hotkeyset=HotKeySet("^+d", "TestFunc")

If $hotkeyset Then
	While 1
		Sleep(100)
	WEnd
Else
	MsgBox(0, "Error oslang=" & @OSLang & " MUILang =" & @MUILang, "HotKeySet (Ctrl+Shift+D) already registered keyboard layout " & @KBLayout)
EndIf

Func TestFunc()
	MsgBox(0, "TestFunc oslang=" & @OSLang & " MUILang =" & @MUILang, "Executed, so keyboard layout " & @KBLayout & ", please switch ...")
	Exit
EndFunc

But it works on my French Win7 see attach HotKeySet.png image

Replying to Jpm:

No output, it's not responding when «Ctrl + Shift + D» pressed, the function is not executed.
And if i change to English layout, it will show this:

Thanks,
So I don't know how to solve the fact that VK code must correspond to the lower case.
in the russian keyboard it must be в.
hotkeyset function don't really care about +d or +D, at least as it is coded.
for russian keyboard. Same kind of problem occur with Send()

Certain keyboard as the Czech one send different characters when using the Shift Key or being in CAPS LOCK enabled and sending a char. Due to the send AutoIt implementation the CAPS LOCKed char will be sent as Shifted one so it will not work.

The only think I can do is to add some warning in HotKeySet doc

[J-Paul Mesnage]

I just found how to detect that +d or +D cannot be register with russian keyboard.
So I will set an @error code with return =0

Fixed by revision [5809] in version: 3.3.7.0

[MrCreatoR <mscreator@…>]

And again, it's not fixed.

[MrCreatoR <mscreator@…>]

Here is the fix i use:

;THIS IS THE FIX!
_WinAPI_LoadKeyboardLayoutEx(0x4109) ;We set English locale as default for our application

;Ctrl + Shift + D
HotKeySet("^+d", "TestFunc")

While 1
	Sleep(100)
WEnd

Func TestFunc()
	MsgBox(0, "TestFunc", "Executed, so default keyboard layout is English, please switch.")
EndFunc

Func _WinAPI_LoadKeyboardLayoutEx($sLayoutID, $hWnd = 0)
	Local Const $WM_INPUTLANGCHANGEREQUEST = 0x50
	Local $aRet = DllCall("user32.dll", "long", "LoadKeyboardLayoutW", "wstr", Hex($sLayoutID, 8), "int", 0)
	
	If Not @error And $aRet[0] Then
		If $hWnd = 0 Then
			$hWnd = WinGetHandle(AutoItWinGetTitle())
		EndIf
		
		DllCall("user32.dll", "ptr", "SendMessage", "hwnd", $hWnd, "int", $WM_INPUTLANGCHANGEREQUEST, "int", 1, "int", $aRet[0])
		Return 1
	EndIf
	
	Return SetError(1)
EndFunc

[J-Paul Mesnage]

I think Autoit does not have the responsability to change the locale.
If the user want, he can do it as you did.
what the fix did was to report the failure in the @error if I remember.
