Create Dll C++ in VS 2015 compatible with Inno Setup

[kassane]

HANDLE __stdcall MyHandle(void)
{
  return AppHandler;
}

to:

extern "C" __declspec(dllexport) HANDLE MyHandle(void)
{
  return AppHandler;
}

My Example: using [Inno-Setup 5.5.1 + DLL(MSVC 2017 x86)] Works!

//MyDll.cpp

#pragma once

typedef long int HWND;

extern "C" __declspec(dllexport) HWND Func(void)
{
	return 30*5; //150
}

extern "C" __declspec(dllexport) HWND Func(void)
{
	return 30*5;
}

not working, same problem occurs

Weird! Well, it worked normally here. Did you test my simple example?

--------------------------------------------------------------------
Update:

-- c++ src updated english strings example
-- Obj. Pascal (freepascal and Delphi) src added
-- setup src and demo

Note: (demo) C++ DLL require vcredist 2017!
Install vcredist 2017:

The problem seems to have already been resolved. Apparently a bad set up the C ++ compiler.

anyway, thank you.

I'm going to upload a file so that you can test it all that you want, and I'd appreciate it if you inform me the result ..
