Help with DLLCall

4 posts in this topic

Hi friends,

I'm working on a licensing project and we are using LexActicvator of Cryptlex.

I'm trying to call a function of a DLL using DLLCall method. I'm calling the method 'SetProductFile' of DLL 'LexActivator_64.dll'. The parameter to the method is path to the product file and the method should return 1 on successful execution. But the method always returns 7 in my test run.

#define LA_E_PFILE ((HRESULT)0x00000007L)
 
/*
    CODE: LA_E_FPATH
 
    MESSAGE: Invalid product file path.
*/
 
The DLL and the product file I use are attached, please save to the script folder to test the script.
Can anyone please help? I'm stuck for many days.

I was unable to locate an API documentation. What are the C prototypes of the functions you'll be using?

Note that the return type should be int64 and the path wstr (most probably).

Hi,

Thank you so much for your reply. They do not have any explicit API documentations than the sample codes provided. Please see the following portion of vb code provided. 

'
        '            FUNCTION: SetProductFile()
        '
        '            PURPOSE: Sets the path of the Product.dat file. This should be
        '            used if your application and Product.dat file are in different
        '            folders or you have renamed the Product.dat file.
        '
        '            If this function is used, it must be called on every start of
        '            your program before any other functions are called.
        '
        '            PARAMETERS:
        '            * filePath - path of the product file (Product.dat)
        '
        '            RETURN CODES: LA_OK, LA_E_FPATH, LA_E_PFILE
        '
        '            NOTE: If this function fails to set the path of product file, none of the
        '            other functions will work.
        '        


        Public Shared Function SetProductFile(filePath As String) As Integer
#If LA_ANY_CPU Then
            Return If(IntPtr.Size = 8, Native.SetProductFile_x64(filePath), Native.SetProductFile(filePath))
#Else
            Return Native.SetProductFile(filePath)
#End If

        End Function

Thank you so much friend, it worked!!!

$aArray = DllCall ( $hDLL , "int64:cdecl", "SetProductFile", "wstr", $sDataFilePath )

      Again, I'm struggling with DllCall(). So I have this MS C++ 6.0 compiled DLL and a manual for it. There's a function:
       
      Get information of disk arrays Declaration: VINT vr_get_array_info (VINT array_index, vr_array_info_t* pinfo); Description: Application can fetch the information of one specific disk array, which is located by index of all disk arrays in current system. Input parameters: VINT array_index : Index to all disk arrays in system, specify which disk array. vr_array_info_t *pinfo : 14 Pointer to a vr_array_info_t data structure to get the information Return value: VR_SUCCESS : Get the information successfully. VR_ERR_NOT_INITED : Raid lib hasn’t been initialized. VR_ERR_INVALID_INDEX : The input index is invalid. VR_ERR_INVALID_PARAM : Input parameter is invalid: the pointer is NULL. Here's what DLL Export Viewer says:
       
      Function Name     : int __cdecl vr_get_array_info(int,struct _vr_array_info *)
      Here's what is this _vr_array_info:
       
      typedef struct _vr_array_info { VWORD status; // current status of disk array VBYTE raidType;// same as Disk_Array.raidType, but value 0xFF means // a stand-alone disk. When it's a stand-alone disk, // only arDevices[0] and diskNum has meaning, and diskNum should // always be 1 . VBYTE diskNum;// count of valid arDevices[] members. // Note: disk array maybe incomplete, i.e. , some disk in the array maybe missing, // corresponding device ptr arDevices[i]->pRealDevice should be NULL. VDWORD capacityLow;// (Unit: sector) VDWORD capacityHigh;// (Unit: sector) // following 8 bytes define the real-capcity (in sector) of every disk in array VDWORD realCapacityLow; // (Unit: sector) VDWORD realCapacityHigh; // (Unit: sector) VDWORD stripeSize; // valid when raid is raid0, raid5 or raid01, in Kbytes VDWORD blockSize; // valid when raid is RAID5, in Kbytes VBOOL bNeedMigration; // the raid need migration // only valid when raid0/raid5/matrixRaid VBOOL bNeedInit; // the raid need initialization, only valid for RAID5 VBOOL bOptimized; // only for RAID5, this RAID5 access was optimized VBYTE systemDisk; /* does the devices within this disk array contain system files of current running OS ? the probably value are: VR_DEVICE_NOT_SYS_DISK VR_DEVICE_MAYBE_SYS_DISK VR_DEVICE_SYS_DISK they are defined in this file */ VWORD raid_index;// only raid index, no meaning with stand-alone disk VINT index; // all device index, including all raid and stand-alone disk } vr_array_info_t;

      Here's my code (function names are actually decorated, so):
       
      Local $pTest $hDLL = DllOpen(@ScriptDir & "\drvInterface.dll") ;~ VINT vr_init (void); ConsoleWrite("vr_init..." & @CRLF) $sTest = DllCall($hDLL, "int:cdecl", "?vr_init@@YAHXZ") ;~ VINT vr_get_controller_num (VINT *pnumber); ConsoleWrite("vr_get_controller_num..." & @CRLF) $sTest = DllCall($hDLL, "int:cdecl", "?vr_get_controller_num@@YAHPAH@Z", "int*", "$pTest") $iControllerNumber = $sTest[1] ConsoleWrite("$iControllerNumber = " & $iControllerNumber & @CRLF) ;~ VINT vr_get_device_num (VINT *pnumber); ConsoleWrite("vr_get_device_num..." & @CRLF) $sTest = DllCall($hDLL, "int:cdecl", "?vr_get_device_num@@YAHPAH@Z", "int*", "$pTest") $iDeviceNumber = $sTest[1] ConsoleWrite("$iDeviceNumber = " & $iDeviceNumber & @CRLF) ;~ VINT vr_get_array_num (VINT only_raid, VINT *pnumber); ConsoleWrite("vr_get_array_num..." & @CRLF) $sTest = DllCall($hDLL, "int:cdecl", "?vr_get_array_num@@YAHHPAH@Z", "int", 0, "int*", "$pTest") $iArrayNumber = $sTest[2] ConsoleWrite("$iArrayNumber = " & $iArrayNumber & @CRLF) $vr_array_info = DllStructCreate("ushort status;byte raidType;byte diskNum;dword capacityLow;dword capacityHigh;dword stripeSize;dword blockSize;boolean bNeedMigration;boolean bNeedInit;boolean bOptimized;byte systemDisk;byte raid_index;int index") ;~ VINT vr_get_array_info (VINT array_index, vr_array_info_t* pinfo); ConsoleWrite("vr_get_array_info..." & @CRLF) $sTest = DllCall($hDLL, "int:cdecl", "?vr_get_array_info@@YAHHPAU_vr_array_info@@@Z", "int", 0, "struct*", $vr_array_info) ;~ void vr_exit (void); ConsoleWrite("vr_exit..." & @CRLF) $sTest = DllCall($hDLL, "none", "?vr_exit@@YAXXZ") DllClose($hDLL) Exit Everything works fine up to vr_get_array_info part. This is where I get a "memory cannot be 'read'" Windows error ("Instruction at 0x7c93a514 referenced memory at 0x00000000").

      What am I doing wrong? Please help.

      Hello!
      There's a DLL, which I want to use in my script. There's the manual for that DLL. I'm trying to use any function from the manual in DllCall() and I get @error=3 ("function" not found in the DLL file). Why is that? How do I fix it?
      PEiD says that DLL is "Microsoft Visual C++ 6.0 DLL". Is that compatible with AutoIt? How do I use it? Please help.

      Hi guys.
      I try to choose an algorithm to compress some string data in-memory, without file medium to store in sqlite as blob. I plan to store about 100k blobs each 80k symbols (uncompressed). First opinion was LZMA udf by Ward, but udf file doesn't exist.
      Then i tried to use BZIP2 dll in DllCall, but it simply doesn't work and throws @error = 1.
       
      Here is an example:
       
      What should I do with this error? Where am I wrong?
      Thanks.

      I'm attempting to call the winapi function EnumSystemFirmwareTables using DllCall "Kernel32.dll" without success. I am a total noob when it comes to this and could use some direction. Based on the documentation "Dealing with Dlls in AutoIt" by Andreas Karlsson, I have tried using the following code to obtain the buffersize of the Firmware Table Buffer.
      Thanks in advance for any help
      #include <WinAPI.au3> MsgBox(0, "ESFT BufferSize", "BufferSize = " & _EnumSystemFirmwareTables()) Func _EnumSystemFirmwareTables() $aRet = DllCall ("Kernel32.dll", "UINT", "EnumSystemFirmwareTables", "DWORD", "ACPI", "PVOID" ,Null , "DWORD" ,Null) if @error Then MsgBox (0,"Error","An error ocurred with the DLLCALL, error returned = " & @error &@CRLF & "GetLastError = " & _WinAPI_GetLastError ( ),0) Exit else Return $aRet endif EndFunc

      Hi, 
      I'm trying to compare two bitmaps (screenshots of the desktop) that I create using BitBlt. The bitmaps can be successfully saved to disk, but when I run the two bitmaps through a CompareBitmaps()-function I found in this thread, which calls memcmp, the script crashes with "Exit code: -1073741819". 
      This crash only happens when I try to compare bitmaps that I got by using BitBlt. If I use the CompareBitmaps()-function on bitmaps created by _GDIPlus_ImageLoadFromFile, everything works fine. (I'm using AutoIT 3.3.6.1)
      I'll attach my script that crashes, and the  CompareBitmaps() example script that works (which I got from the thread previosly mentioned)
      My script, that for some reason crashes : 
      #include <ScreenCapture.au3> #include <GDIPlus.au3> #include <WinAPI.au3> _GDIPlus_Startup() Local $hDesktop = _WinAPI_GetDesktopWindow() $clientS = WinGetClientSize($hDesktop) Local $Width = $clientS[0] Local $Height = $clientS[1] Local $hDC = _WinAPI_GetDC($hDesktop) Local $memDC = _WinAPI_CreateCompatibleDC($hDC) Local $memBmp = _WinAPI_CreateCompatibleBitmap($hDC, $Width, $Height) _WinAPI_SelectObject ($memDC, $memBmp) _WinAPI_BitBlt($memDC, 0, 0, $Width, $Height, $hDC, 0,0, $__SCREENCAPTURECONSTANT_SRCCOPY) _WinAPI_DeleteDC($memDC) _WinAPI_ReleaseDC($hDesktop, $hDC) Local $hImage1 = _GDIPlus_BitmapCreateFromHBITMAP($memBmp) _WinAPI_DeleteObject($memBmp) _GDIPlus_ImageSaveToFile($hImage1, @ScriptDir & "\GDIPlus_Image1.jpg") MsgBox(0, "Debug", "Screenshot taken & saved to disk.

      Any one got a clue why my script crashes?
