How to include NModbus

[caspar_h...@hotmail.com]

I like to use NModbus for some hobby and studying but I can't get the
implementation included... I like to use NModbus in a C++ or C#
project environment.

Can you tell me with which software I can include the NModbus
implementation and in what way?

Thanx in advance,

With kind regards,

Caspar

Copy the Modbus and log4net dlls into the same directory and add a
reference to the Modbus dll.

How do I add such a reference in Visual Studio using C++?

What I did was:

#using "Modbus.dll"

And I have copied the .dll file in the main project directory..

But I always get the message:

fatal error C1190: managed targeted code requires '#using
<mscorlib.dll>' and '/clr' option

I've no idea what I'm doing wrong..

It sounds like you're selecting the wrong type of C++ project from
within Visual Studio. I don't know what version of Visual Studio you
have, but in VS 2005 (and 2008 Beta 2) Professional, in the "New
Project" dialog, "Visual C++" is an expandable tree node. If you click
the plus sign (or arrow on Vista) to expand the node, you should see
something like:
- ATL
- CLR
- General
- MFC
- Smart Device
- Win32

To reference NModbus in a C++ project, you want to select from the CLR
group of project types. This will enable the compiler switch (/clr)
required to reference the NModbus assembly.

Hope that helps, and good luck
Jacob.

Ah! I see.. Thank you very much!
I'm working with VS 2003.. But under C++ projects I see:

- .NET
- ATL
- MFC
- Win32
- General

So I think I need a new(er) version of VS.. I hope I can get one and
then getting started :)

Kind regards,

Caspar

Now I'm using Visual C++ Express Edition (a 30 days trial) and I think
the including is succeeded.
But now I have the following problem;

I always getting the following message:
An unhandled exception of type 'System.IO.FileNotFoundException'
occurred in Unknown Module.

Additional information: Could not load file or assembly 'Modbus,
Version=1.2.0.0, Culture=neutral, PublicKeyToken=null' or one of its
dependencies.

What am I doing wrong this time?

Kind regards,

Caspar

My code now:
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
#include "stdafx.h"
#include <iostream>
#include <string>

#using "Modbus.dll"
#using "log4net.dll"

using namespace std;

using namespace System;
using namespace System::Diagnostics;
using namespace System::IO::Ports;
using namespace System::Threading;
using namespace Modbus;
using namespace Modbus::Device;

void main()
{
SerialPort port("COM2");

// configure serial port
port.BaudRate = 9600;
port.DataBits = 8;
//port.Parity = Even;
//port.StopBits = StopBits.One;
port.Open();

// create modbus master
IModbusSerialMaster^ master;
//IModbusSerialMaster^ CreateRtu(port);

unsigned char slaveID = 10;
unsigned short startAddress = 10;
unsigned short registers = 5;

// write three registers
master->ReadHoldingRegisters(slaveID, startAddress, registers);

cin.get();
}

Is there also an example of a Modbus master in C++..?

I think I'm using a lot of function confusedly.. So I can see how it
works and build it to my own requirements..
