Call to my Dll returing Array of nos. Not working.

Recommended Posts

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.

The easiest way to use C# and VB.NET code in AutoIt is to use the techniques demonstrated in this example.

Thanks LarsJ, It worked. 

Truly appreciate this. Also more so since this was not in the FULL version downloaded and also showed me the example.

      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

      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?

      Hi -
      Currently I'm playing around with Windows Credential Manager. I'm trying to access it with DllCall("advapi32.dll", ...) using the functions 'CredWriteW', 'CredReadW' and 'CredDeleteW'. All well. Another function I have to deal with is 'CredEnumerateW': https://docs.microsoft.com/en-us/windows/desktop/api/wincred/nf-wincred-credenumeratew/ .
      That's the test code I have so far:
      #include <Array.au3> #include <String.au3> Local $tCredentialsCount = DllStructCreate("DWORD;") Local $tPointerToArrayOfPointers = DllStructCreate("PTR;") ; Local $tPointerToArrayOfPointers = DllStructCreate(_StringRepeat("PTR;", 200)) ; ??? Local $aResult = DllCall("advapi32.dll", "BOOL", "CredEnumerateW", _ "WSTR", Null, "DWORD", 1, "DWORD", DllStructGetPtr($tCredentialsCount), "PTR", DllStructGetPtr($tPointerToArrayOfPointers)) If (Not @error) Then Local $iCredentialsCount = DllStructGetData($tCredentialsCount, 1) _ArrayDisplay($aResult, $iCredentialsCount) Local $hPointerToArrayOfPointers = DllStructGetData($tPointerToArrayOfPointers, 1) MsgBox(0, "$hPointerToArrayOfPointers", $hPointerToArrayOfPointers) ; Fails... For $i = 1 To 10 ; $iCredentialsCount MsgBox(0, $i & "___" & (($i * 2) - 1), DllStructGetData($tPointerToArrayOfPointers, ($i * 2) - 1)) Next $tCredentialsCount = 0 $tPointerToArrayOfPointers = 0 DllCall("advapi32.dll", "NONE", "CredFreeW", "PTR", $hPointerToArrayOfPointers) EndIf The DllCall seems to function properly - I get a valid count of credentials (on my computer ~ 133) and a pointer "to array of pointers".
      What is meant by "array of pointers"?
      Microsoft says: Pointer to an array of pointers to credentials. The returned credential is a single allocated block. Any pointers contained within the buffer are pointers to locations within this single allocated block.
      How to access these pointers... Contained within the buffer???
      Any information you can provide me would be greatly appreciated.

      Hello,
      i need help to translate the c code to autoit .
      I don't understand the callback function.
       
      #include <windows.h> #include <stdio.h> // native IR Data by PAnsiChar typedef void CALLBACK CallBackPAnsiChar(char*, char*, char*, char*); typedef int (__stdcall *impInitPAnsiChar)(CallBackPAnsiChar); CALLBACK MyCallBackPAnsiChar(char* Protocol, char* Address, char* Command, char* Flags) { printf("\nIR Data received: Protocol: %s, Address: 0x%s, Command: 0x%s, Flags: 0x%s", Protocol, Address, Command, Flags); fflush(stdout); } int main(int argc, char **argv) { impInitPAnsiChar InitPAnsiChar = NULL; // Load DLL file HINSTANCE hinstLib = LoadLibrary(TEXT("USB_IR_Remote_Receiver.dll")); if (hinstLib == NULL) { printf("\nERROR: unable to load DLL\n"); return 1; } // Get function pointer InitPAnsiChar InitPAnsiChar = (impInitPAnsiChar)GetProcAddress(hinstLib, "InitPAnsiChar"); if (InitPAnsiChar == NULL) { printf("\nERROR: unable to find DLL function\n"); FreeLibrary(hinstLib); return 1; } if (InitPAnsiChar(*MyCallBackPAnsiChar)) { printf("\nInit DLL with InitPAnsiChar successfull"); } else { // Unload DLL file FreeLibrary(hinstLib); return 0; } while(1) { } //return 0; }
