DLLCall returns AutoIt3.exe error

I just started using DLL functions in autoit and I found a short tutorial about DLL calling. ( https://www.autoitscript.com/forum/topic/93496-tutorial-on-dllcall-dllstructs/ )

I just copied some code form the examples he gave me. But when I run the code below my SciTe Editor runs for about 10 seconds and then crashes with error code:

!>11:31:16 AutoIt3.exe ended.rc:-1073741819
$SYSTEMTIME=DllStructCreate("ushort wYear;ushort wMonth;ushort wDayOfWeek;ushortwDay;ushort wHour;ushort wMinute;ushort wSecond;ushort wMilliseconds")
DllCall("Kernel32.dll","none","GetSystemTime","ptr",DllStructGetPtr($SYSTEMTIME))
MsgBox(0,"Currenttime:",DllStructGetData($SYSTEMTIME,"wHour")&":"&DllStructGetData($SYSTEMTIME,"wMinute"))

Is there something wrong with the code? Or is it a bug in the SciTe Editor?
I also read something about the "cdecl" calling method. Has this something to do with it? When do I need to use it? And how can I know this when to use?

Also some information about my SciTe version etc.

SciTe version: 3.4.1
Architecture: X64
OSBuild: 7601
SP: Service Pack 1
OS Type: WIN32_NT
OS Verison: WIN_7

Looks like a typo.

$SYSTEMTIME=DllStructCreate("ushort wYear;ushort wMonth;ushort wDayOfWeek;ushort wDay;ushort wHour;ushort wMinute;ushort wSecond;ushort wMilliseconds")
DllCall("Kernel32.dll","none","GetSystemTime","ptr",DllStructGetPtr($SYSTEMTIME))
MsgBox(0,"Currenttime:",DllStructGetData($SYSTEMTIME,"wHour")&":"&DllStructGetData($SYSTEMTIME,"wMinute"))

 

Note: ushort wDay

      Use mimeTools.dll of Notepad++
      By Colduction
      Hi AutoIt Scripters/Programmers. I have a question about MIME Tools for Notepad++:
      I've recently found a UDF about Base64 in forum, but they can't decode\encode correctly some emojis , other UTFs and etc. so i decided to use mimeTools.dll of Notepad++ or main site
      My problem is how to use this dll in AutoIt Language?

      I will be happy with your comments and answers❤ Thanks.

      Use C/C++ DLL in VBA
      By FrancescoDiMuro
      Good morning Forums 
      In these days, I am working on a project that involved me to use some Windows APIs to obtain some information about Terminal Servers.
      I'm doing this using wtsapi32.dll in a VBA Project, but, the lack of knowledge about few things threated in the articles make this quite difficult to
      implement and understand at the same time.
      The most difficult thing I'm facing is "translating" C/C++ functions or struct in VBA when pointers are used, or pointers of pointers, and so on.
      Since VBA seems to not have a pointer type, to make those functions work I need to implement other functions taken from other DLLs, and this confuses me a lot.
      For example, starting from this code, I splitted all the functions and all the definitions to understand why they are there, and why I need to use them.
      At the end, I've found out that the code I was going to implement starting from the functions provided in the Microsoft Docs won't be ever be able to work without some supplementary functions which are not mentioned anywhere.
      So, I was wondering if someone would please point me out to a good and practical exaplanation about pointers (in general) or specifically for VBA, because I need to use them quite often in these days, and I'd like to understand what I am doing.
      Thanks in advance.

      Best Regards and Stay at home 🏡

      All my scripts were working fine and now I am getting this error.  How do I resolve it?  Which folder(s) do the DLLs need to be in?

      Controll Acroname Programmable USB Hub (BrainStem)
      By RAMzor
      Hello all!
      I got the Acroname Programmable USB Hub based on BrainStem platform. I will use it to manage ports and read current.
      They have development kit (BRAINSTEM DEVELOPMENT KIT) with examples for any languages like C#, C++, LabVIEW and python but no AutoIt.
      The kit include BrainStem2.dll (x32 and x64), BrainStem2_LabVIEW.dll, BrainStem2CLI.dll and many examples.
      Anyone used this dll and implemented it in AutoIt?
      Please share some example for Device Discovering, User LED Flashing or power enable/disable on port to start play with this HUB
