get mouse double click time issue

[NerdFencer]

I am beginning to write a mouse UDF library, I am having an issue with the _MouseGetDoubleClickTime function, the DllCall Error code is 1 (unable to use the DLL file)

Here is that function (with some debug code), a call to it, and another function that uses the same dll file that works

MsgBox(0,"Double Click Time",_MouseGetDoubleClickTime())
; #FUNCTION# ====================================================================================================================
; Name...........: _MouseButtonSwap
; Description ...: Sets the mouse buttons to either swapped or not
; Syntax.........: _MouseButtonSwap($fOn)
; Parameters ....: $fOn         - True-Swapped False-Normal
; Return values .: Success      - >0:Was reversed Before  0:Was not reversed before
;                  Failure      - -1
; Author ........: NerdFencer
; ===============================================================================================================================
Func _MouseButtonSwap($fOn)
    If Not($fOn==True) And Not($fOn==False) Then Return SetError(1,0,-1)
    Return DllCall(@WindowsDir&"\system32\user32.dll","byte","SwapMouseButton","byte",$fOn)
EndFunc

; #FUNCTION# ====================================================================================================================
; Name...........: _MouseGetDoubleClickTime
; Description ...: Gets the double click time
; Syntax.........: _MouseGetDoubleClickTime()
; Return values .: Success      - the current double-click time in milliseconds
; Author ........: NerdFencer
; ===============================================================================================================================
Func _MouseGetDoubleClickTime()
    $retval=DllCall(@WindowsDir&"\system32\user32.dll","uint","GetDoubleClickTime","none",False)
    MsgBox(0,@error,$retval)
    Return $retval
EndFunc

Also, here is the documentation on that function http://msdn.microsoft.com/en-us/library/ms646258(VS.85).aspx

Does anybody know what I am doing wrong?

lol It was so embarrassing to not find the problem. Anyway you shouldn't call this function with "none" and False at all:

$retval = DllCall('user32.dll', 'uint', 'GetDoubleClickTime')
ConsoleWrite(@error & ': ' & $retval[0] & @CRLF)

Thanks, it works

I figured that it was just something stupid like that, but I just wasn't seeing it...
