NI 488.2 can support VS2013?

[JackieLin]

I have add reference "NationalIstruments.NI4882", but can't coding 488.2 command. please see below picture.

My OS is WIN 7 64 bit, VS2013, MAX v15.0.0f0, upgrate to new version.

Below is my code, can't to build, NI488 code can't complete compile.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Ivi.Visa.Interop; //VisaComLib
using NationalInstruments.NI4882;
using NationalInstruments.VisaNS;

namespace xxx
{
    class Program
    {
      private MessageBasedSession mbSession;

        static void Main(string[] args)            

        {
          int noncontroller;
          char[] buffer = new char[100];
          int panelHandle;
            //Open  session to the GPIB board
            noncontroller = ibfind ("gpib0");

            //Release system control
            ibrsc(noncontroller, 0);

            //Change GPIB primary address from 0 to 2
            ibpad(noncontroller, 2);

            while(true)
            {
                //Update status variable
                ibwait(noncontroller, 0);

                //Wait until non-controller is listener and ATN line is dropped.
                if ((ibsta&LACS)&&(!(ibsta&ATN)))
                {
                    ibrd(noncontroller, buffer, 100); // Read data bytes
                    buffer[ibcnt] = '\n'; //Add linefeed and 0 to string
                    buffer[ibcnt + 1] = 0;
                    Console.WriteLine("Buffer Value{0}", buffer);
                    //printf("%s", buffer); // Print buffer for C
                    return;
                }
            }
        }
    }
}

If you the newest NI-488.2 installed, it should support .NET Framework 4.5.1

[JackieLin]

Yes, can support .NET Framework 4.5.1, so only can use .NET to programming?

I don't understand your question.

Visual Studio uses .NET

[JackieLin]

I think loss NationalInstruments.Common,but add reference, can't include program, please see below picture.

NationalInstruments.Common verison is 15.0.40.49154

.Net Framework 4

Confirm NI4882.dll is working, but can't use ibfind,ibwait..... command, i don't know why?

Hi,

You set a reference to the GPIB .NET library, but you using the old Win32 function calls.

ibfind, ibread etc...

You need to use the NI488.2 Class library objects and methods

Check the examples located at the followng link

Thanks and understood, but use .NET library, any document can read, because for Win32 have NI-488.2 user manual for reference to programming, such as ibfind,ibwrt...etc, but .NET only example program, i don't know which command same ibfind?

[JackieLin]

I think find maybe answer,please see path http://zone.ni.com/reference/en-XX/help/370628F-01/mstudiowebhelp/html/gpibapimapping/

Hi,

You need to create a Board object.

Address boardAddress;
        Board board;

        private void butOpen_Click(object sender, EventArgs e)
        {
            bool retval = false;

            try
            {

                boardAddress.PrimaryAddress = 0;
               
                board = new Board();  //defaults to 0 for GPIB board index number 'GPIB0'. Change to your board number idf required

                retval = board.FindListener(boardAddress);

                Debug.WriteLine("FindListener returned " + retval.ToString());

                board.IsSystemController = false;

                retval = board.IsSystemController;

                Debug.WriteLine("IsSystemController returned " + retval.ToString());


 
            }
            catch (Exception ex)
            {

                Debug.WriteLine(ex.Message.ToString());
   
            }
        }

Debug Output

FindListener returned True

IsSystemController returned False

Good luck!
