      Hi,
      My AutoIt script is as folllows:
      ;use for calling function add2NosA in dll ;Local $vNo1 = 33 ;Local $vNo2 = 11 ;use for calling function sortNos in dll Local $vNo1 = [11,7,9] Local $vNo2 = [1,3,2] ; _ArrayDisplay($vNo1, "vNo1 display") ; _ArrayDisplay($vNo2, "vNo2 display") ;Local $hWnd = DllOpen("E:\CV-Dell-1\autoit3\myComObj1.dll") Local $hWnd = ObjCreate("myComObj1.clsMath") if (@error) Then MsgBox (0, "Error", "Error1 = " & @error) Exit EndIf ;function call method - DllCall with function name ;Local $aRes = DllCall($hWnd, "int", "addNosA", "int", $vNo1, "int", $vNo2) ;Local $aRes = DllCall($hWnd, "Ptr", "sortNos", "Array", $vNo1, "Array", $vNo2) ;function call method - $hWnd.<function name> ;Local $aRes = $hWnd.add2NosA($vNo1, $vNo2) ; this works fine with ObjCreate Local $aRes = $hWnd.sortNos($vNo1, $vNo2) if (@error) Then MsgBox (0, "Error", "Error2 = " & @error) DllClose($hWnd) Exit EndIf ;use appropriate msgbox ;MsgBox(0,"Result", "Result = " & $vNo1[0]) MsgBox(0,"Result", "Result = " & $aRes) _ArrayDisplay($vNo1, "vNo1 display") _ArrayDisplay($aRes , "aRes display") DllClose($hWnd) My VB.Net - ClassLibrary - Dll - COM obj is as follows - has 2 functions - add2NosA and sortNos:
      <ComClass(clsMath.ClassId, clsMath.InterfaceId, clsMath.EventsId)> Public Class clsMath Public Const ClassId As String = "3A42F85E-24C8-4BAA-91B5-AE56C4683C13" Public Const InterfaceId As String = "D99D7C79-2BA7-4A33-B7BC-9B7F19FDF828" Public Const EventsId As String = "CA128AC4-580C-4112-9EAD-8D1599E3F37A" Public Sub New() MyBase.New() End Sub Public Function add2NosA(ByVal no1 As Integer, ByVal no2 As Integer) As Integer Return (no1 + no2) End Function Public Sub sortNos(ByRef no1 As Array, ByRef no2 As Array) Array.Sort(no1) no2 = no1 End Sub End Class  Over all I tried various 8 options mentioned in the attached Excel file - with only 1 combination working.
      Overall could not make Array returned capture in AutoIt script. 
      Can someone help please?
      Thanks in  advance.

      I have create a function in FreeBasic like below:
      Extern "Windows-MS" Type tA f1 As Integer f2 As Integer End Type Public Function _switchOrder(ByVal no1 As Integer, ByVal no2 As Integer) As tA Export Dim result As Integer Dim taa As tA taa.f1 = no2 taa.f2 = no1 Return taa End Function End Extern Caller AutoIt code is:
      #include <MsgBoxConstants.au3> Global Const $sTag_ftdi_version_info="struct; int no1a; int no2a; endstruct" Local $aRet=DllCall("Math1.dll","Ptr","_switchOrder", "Int", 10, "Int", 30) ;MsgBox (0,"",@error & "-" & $aRet[0] & "-" & $aRet[1]& "-" & $aRet[2]) Local $t_ftdi_version_info=DllStructCreate($sTag_ftdi_version_info,$aRet[0]) MsgBox (0,"msg1=",@error & "---" & $aRet[0] & "-" & $aRet[1]& "-" & $aRet[2]) ;Local $retData1 = DllStructGetData($t_ftdi_version_info,"",1) Local $retData1 = DllStructGetData($t_ftdi_version_info,"no1a") MsgBox (0,"msg2=",@error & "--" & $retData1) ;Local $retData1 = DllStructGetData($t_ftdi_version_info,"",2) Local $retData1 = DllStructGetData($t_ftdi_version_info,"no2a") MsgBox (0,"msg2=",@error & "--" & $retData1) ;ConsoleWrite(DllStructGetData($t_ftdi_version_info,"",2) & "--" & @error) ;ConsoleWrite(DllStructGetData($t_ftdi_version_info,"no2a") & @CRLF) ;ConsoleWrite(DllStructGetData($tversion_str,1) & @CRLF) Getting error 2 for DllStructGetData or it give Close Application AutoIt popup message. 
      Certainly DllCall is not returning pointer to the Structure in $aRet[0] hence issue.
      Can someone help me fix this please?
      Thanks in advance.

      This simple dllcall gives me error 5, access denied,
      Func _WinAPI_VkKeyScan($__key) _WinAPI_SetLastError(0) $res = DllCall('User32.dll', 'SHORT', 'VkKeyScan', 'CHAR', $__key) _xConsole('res: '&$res) $_LastErr = _WinAPI_GetLastError() If $_LastErr <> 0 Then _xConsole('Err: {' & $_LastErr & '}> ' & _WinAPI_GetLastErrorMessage()) Return $res EndFunc Am i doing something wrong?
      Also tried VkKeyScanA and W
      Edit:
      I want to send `:` via PostMessage() WM_KEYDOWN

      Hi All,
      I didn't know where to put this; my apologies if this is the wrong location.
      When you plug a Samsung mobile device (phone, tablet, etc.) into the USB of a Windows PC, you can right-click the device in My Computer and select Properties. Here, it will show you the correct serial number of the device. Clearly Windows doesn't use adb to get the SN so I'm stuck at how to get the SN without adb and where the device doesn't have a drive letter assigned to it.
      When I last picked this up, I tried seemingly everything I could from wmi(?) and winmgmts(?) but either it's hidden cloak-and-dagger style or I can't see the forest for the trees...
      Does anyone know what API Windows uses when getting the serial number of a device Windows calls a Portable Media Player?

      This is relevant
      From here https://stackoverflow.com/questions/3454315/is-it-possible-to-pin-a-dll-in-memory-to-prevent-unloading
      I use several UDFs on the Forum to do various things.  Those UDFs work very well.
      Effectively the UDFs are DLL wrappers, that make it possible to access DLL functions easily without the long hard slog of DLLCall() every time.
      However, I have now run into the issue that multiple UDF DLLCalls are slow. Not mind numbingly slow, but slow enough to become noticeable with a large of repeated function calls.
      So I was wondering, is it possible to "load a DLL into memory" and leave it there for the duration of my script's lifetime, avoid repeated DLL on-disk reads with a persistent in memory DLL?
      From Microsoft
      https://docs.microsoft.com/en-us/windows/desktop/dlls/about-dynamic-link-libraries
      Looks like what I want to do is: load-time dynamic linking,
      So next question, (a) how do I do this with AutoIt (b) How would this impact on standard AutoIt type DLL calls?
       
      The point is speed.  Is there a different approach?
      Or am I barking up the wrong tree?
