Question

Hi, I want to build a small application that can control a bunch of led's connected to the parallel port. From what I've read over the internet, I've come to know that I have to use Inpout32.dll for accessing the port.

> I have downloaded 'Inpout32.dll' and 'inpout.lib', now how do I include it in my visual c++ project. I'm using Visual Studio 11 Ultimate and I'm making a c++ console application.

> What functions do I have to use to send data to the parallel port?

> Can someone point me to a good, lucid, clear tutorial/example other than http://www.lvr.com/parport.htm[^]

That is a good tutorial, but I want to do it using Inpout32.dll in a console application, no MFC.

What are you talking about?! Ever heard of separation of concerns? MFC is irrelevant here. Don't want it (I understand it very much), don't use it...

From the whole code, I couldn't separate the port stuff from the MFC stuff.

Well, sorry. I wish I've written the C++ library and demo, but I didn't :-)
However, I would advise you not to rely on something which is ready-to-use, better put some effort.
Good luck,

Alright, can you tell me how do I include the 'Inpout32.dll' in my project (visual c++ consol application, visual studio 11)?

Sergey Alexandrovich Kryukov 2-Mar-13 20:18pm

Never tried that one... in a usual way, I think... :-)

I wrote this code:

#include "stdafx.h"
#include "stdio.h"
#include "string.h"
#include "stdlib.h"
#include <conio.h>

short _stdcall Inp32(short PortAddress);
void _stdcall Out32(short PortAddress, short data);

int main(int argc, char* argv[])
{

Out32(888, 255);
system("pause");
Out32(888, 0);

return 0;
}

Is this not supposed to turn on all led's first then turn them off? Nothing happened.
