Hi guys,

thanks to this request, I wrote my version of GetLogicalProcessorInformation UDF for x86 e x64:

; #FUNCTION# ========================================================================================================================
; Name...........: _WinAPI_GetLogicalProcessorInformation
; Description ...: Retrieves information about logical processors and related hardware.
; Syntax.........: _WinAPI_GetLogicalProcessorInformation()
; Return values .: On success it returns a bidimensional array: on rows there is the list of processor sets, these are the columns:
;                  |[0] - A logical processor affinity mask, which indicates the logical processors that the information applies to.
;                  |[1] - If setted, then the specified logical processors share a single processor core.
;                  |[2] - How many active processors that share functional units are in the relationship
;                         (it is setted only if the previous element is setted too)
;                  |[3] - If setted, it identifies the NUMA node (it can be 0).
;                  |[4] - If setted, the specified logical processors share a physical package.
;                  |[5] - A bidimensional array: on rows there is the cache list, these are the columns:
;                         |[0] - The cache level
;                         |[1] - The cache associativity
;                         |[2] - The cache line size, in bytes
;                         |[3] - The cache size, in bytes
;                         |[4] - The cache type
;                  On failure it returns -1 and sets @error to non zero:
;                  |-1 - internal error
;                  |-2 - missing DLL (Ws2_32.dll)
; Remarks .......: Search GetLogicalProcessorInformation in MSDN Library.

 Nice version. Thank you. dllcall return type should be BOOL instead BOOLEAN.

 

Saludos

      Hi I need help with the code bellow, my goal is to make faster sqlite queries to Sqlite because _SQLite_GetTable2d seams to be slow on big tables.
      Thank you :
       
      https://www.autoitscript.com/forum/topic/182469-using-controls-to-edit-cells-in-a-listview/
       
      Well my code is faster but a I have 2 issues :
      1 Memory leaks
      2 Listview ( virtual) a little slow when scrolling (column headers delay )
      Please help I am not a WinApi specialist. (The hugetable its actuality much bigger I'm limited by upload size)
      Thank You.

      Hi, I need the help of some "C++ Pros" of you....

      The "WINAPI GetLogicalProcessorInformation" function does not exists in the AutoIt Includes, so I decided to build it on my own ....no success so far.
      I adapted easy functions, but this one seems to be odd and unfamiliar.

      I hope somebody can help me.... and after that this function should be added to the Includes (WinAPISys.au3).

      Edit: If you already read this post, I updated it to better fit the scope of what I want to do.

      My goal is to be able to read the raw output from a usb type controller (or mouse or keyboard, don't want it to be controller-only) so i can see how / what changes when i hit buttons. I've gotten as far as finding HID page documentation and documentation for the device Struct, but I don't know where to go from here
      How do I tell what and Useage to use for any given controller / Keyboard / Mouse? How do I get a list of all HID devices connected and their UsagePage / Usage? How do I register multiple devices / get raw input from multiple devices at once? Here is the modified example script i am using:
      #include <APISysConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WinAPIGdi.au3> #include <WinAPIMisc.au3> #include <WinAPISys.au3> #include <WindowsConstants.au3> Opt('TrayAutoPause', 0) Global $iFlagsOld = 0, $iDataOld = 0 ; Create GUI Global $g_hForm = GUICreate('Test ' & StringReplace(@ScriptName, '.au3', '()'), 160, 212, @DesktopWidth - 179, @DesktopHeight - 283, BitOR($WS_CAPTION, $WS_POPUP, $WS_SYSMENU), $WS_EX_TOPMOST) ; To obtain the values of "UsagePage" and "Usage" members of this structure read HID Usage Tables documentation ; http://www.usb.org/developers/devclass_docs/HID1_11.pdf ; Disregaurd that, official USB documention = useless. Here is a human/normal-person friendly list ; http://www.freebsddiary.org/APC/usb_hid_usages.php ; Information on the Struct (eg what Flags and hTarget do) can be found here ; https://msdn.microsoft.com/en-us/library/ms645565(v=vs.85).aspx Local $tRID = DllStructCreate($tagRAWINPUTDEVICE) DllStructSetData($tRID, 'UsagePage', 0x01) ; Generic Desktop Controls DllStructSetData($tRID, 'Usage', 0x06) ; Mouse DllStructSetData($tRID, 'Flags', $RIDEV_INPUTSINK) ; This flag makes window hTarget accept input even when it's not active. MUST define hTarget DllStructSetData($tRID, 'hTarget', $g_hForm) ; The target window that will be sent events, used with some Flags ; Register HID input to obtain row input _WinAPI_RegisterRawInputDevices($tRID) ; Register WM_INPUT message GUIRegisterMsg($WM_INPUT, 'WM_INPUT') ;~ GUISetState(@SW_SHOW) Do Until GUIGetMsg() = $GUI_EVENT_CLOSE Func WM_INPUT($hWnd, $iMsg, $wParam, $lParam) #forceref $iMsg, $wParam Switch $hWnd Case $g_hForm Local $tRIM = DllStructCreate($tagRAWINPUTMOUSE) If _WinAPI_GetRawInputData($lParam, $tRIM, DllStructGetSize($tRIM), $RID_INPUT) Then Local $iFlags = DllStructGetData($tRIM, 'Flags') Local $sFlag = "", $sData = "" $iFlags = DllStructGetData($tRIM, 'ButtonFlags') If $iFlags <> $iFlagsOld Then $sFlag = $iFlags $iFlagsOld = $iFlags EndIf $iData = DllStructGetData($tRIM, 'ButtonData') If $iData <> $iDataOld Then $sData = $iData $iDataOld = $iData EndIf If $sFlag&$sData <> "" Then ConsoleWrite($sFlag&" "&$sData&@CRLF) EndIf EndIf EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_INPUT

      Function for enabling Aero-like blur effect in Windows 10.
    • scintilla4evr
      By scintilla4evr
      Hello! As some of you probably know, _WinAPI_DwmEnableBlurBehindWindow does not work as you'd like it to work in Windows 10. It doesn't add Aero-like blur, as seen in the new Start menu or Notification Center. I looked for a solution and found "the most elegant" one:

      The blur only affects the inside of the window and it is not colored. It can be enabled via an undocumented SetWindowCompositionAttribute function in user32.dll.
      _WinAPI_DwmEnableBlurBehindWindow for Windows 10 - this archive contains both the UDF and the example.
