Special Keys on Logitech K350

8 posts in this topic

I'm using a Logitech K350 keyboard. On the left hand side of the keyboard, there are two buttons to zoom in or to zoom out. It is similar to CTRL + mouse wheel in Firefox. I wanna map these two keys. How do I do that? Is there a tool to record key codes by pressing them?

I had the exact same question today. I have a Lenovo keyboard that has a calculator button that doesn't pull up the calculator when I press it. Here's something that I found that helped me:

However, the calculator key I wanted to re-map did not show up. I guess it's non-standard and AutoIt could not recognize it. AutoIt recognized all other keys. Good luck!

Did you try the _WinAPI_IsPressed Function example that comes with the WinAPIEx UDF?

In the link which you have posted, an example is given. I've tested it. It displays me the shift key while I press the zoom in/out key. Strange. How exactly do you have solved your problem?

Yeah.

And The result is?

....

Opt('GUICloseOnESC', 0)
Opt('MustDeclareVars', 1)

Global $Label, $Key, $Prev = Default

GUICreate('MyGUI', 200, 200)
$Label = GUICtrlCreateLabel('', 10, 59, 180, 82, 0x01)
GUICtrlSetFont(-1, 48, 400, 0, 'Tahoma')
GUISetState()

While 1
    Sleep(10)
    If GUIGetMsg() = -3 Then
        ExitLoop
    EndIf
    $Key = 0
    $Key = _WinAPI_IsPressed(0x00, 0xFF)
    If $Key <> $Prev Then
        GUICtrlSetData($Label, '0x' & Hex($Key, 2))
        $Prev = $Key
    EndIf
WEnd


Func _WinAPI_IsPressed($iFrom = 0x01, $iTo = 0xFF)

    Local $tData = _WinAPI_GetKeyboardState()

    If @error Then
        Return SetError(1, 0, 0)
    EndIf

    For $i = $iFrom To $iTo
        Switch $i
            Case 0x0A, 0x0B, 0x0E To 0x0F, 0x16, 0x1A, 0x1C To 0x1F, 0x3A To 0x40, 0x5E, 0x88 To 0x8F, 0x97 To 0x9F, 0xB8 To 0xB9, 0xC1 To 0xDA, 0xE0, 0xE8
                ContinueLoop
            Case Else
                If BitAND(DllStructGetData($tData, 1, $i + 1), 0xF0) Then
                    Return $i
                EndIf
        EndSwitch
    Next
    Return 0
EndFunc   ;==>_WinAPI_IsPressed


Func _WinAPI_GetKeyboardState()

    Local $tData = DllStructCreate('byte[256]')
    Local $Ret = DllCall('user32.dll', 'int', 'GetKeyboardState', 'ptr', DllStructGetPtr($tData))

    If (@error) Or (Not $Ret[0]) Then
        Return SetError(1, 0, 0)
    EndIf
    Return $tData
EndFunc   ;==>_WinAPI_GetKeyboardState

Nothing changes while I'm pressing the zoom in/out key. So the result is 0x00.
