Hello,

I installed EMDK for .Net and made a simple application to connect to an FX-7400 RFID reader but got the following error:

System.EntryPointNotFoundException: 'Unable to find an entry point named 'RFID_AllocateRFSurvey' in DLL 'rfidapi32pc.dll'.'

EMDK: emdk-m-020900.exe

Please advise,

Source Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Symbol.RFID3;

namespace TestRFID
{
    class Program
    {
        static void Main(string[] args)
        {
            RFIDReader reader;
            reader = new RFIDReader("xxx.xxx.xxx.xxx", 5084, 0);
            reader.Connect();

        }
    }
}

Just an FYI: 

The FX7400 is no longer supported.


The Example Code that uses the 32-bit driver from the EMDK - I would suggest (as-is) is the Dot-Net CS_Sample1 and CS_Sample2 apps that are bundled with the EMDK - but the Newer the Legacy EMDK is - it was modified / updated to connect to FX7500 and FX9600 readers that supercede the FX-Series reader you refer to, and less support for the FX7400 and the FX9500 - See these support portal here:

Thank you for comments,

The latest drivers do not work with FX-7400, and I downgrade to 2.5. So problem solved!

Thanks for that update Vahid.
