Hi I am getting the error below on the line marked ERROR HERE in the following VB.net code, which I converted using an online tool from the C# code below.

Error      3      Class 'SAPSystemConnect' must implement 'Event ConfigurationChanged(destinationName As String, args As RfcConfigurationEventArgs)' for interface 'SAP.Middleware.Connector.IDestinationConfiguration'.

Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports SAP.Middleware.Connector


Public Class SAPSystemConnect

    Implements IDestinationConfiguration 'ERROR HERE
    Public Function ChangeEventsSupported() As Boolean
        Throw New NotImplementedException()
    End Function

    Public Event ConfigurationChanged As RfcDestinationManager.ConfigurationChangeHandler

    Public Function GetParameters(destinationName As String) As RfcConfigParameters
        Dim parms As New RfcConfigParameters()
        If "Dev".Equals(destinationName) Then
            parms.Add(RfcConfigParameters.AppServerHost, "000.000.000.000")
            parms.Add(RfcConfigParameters.SystemNumber, "95")
            parms.Add(RfcConfigParameters.User, "sap_user")
            parms.Add(RfcConfigParameters.Password, "xxxxxxxxxx")
            parms.Add(RfcConfigParameters.User, "10")
            parms.Add(RfcConfigParameters.User, "EN")
            parms.Add(RfcConfigParameters.User, "5")
            parms.Add(RfcConfigParameters.User, "10")
            parms.Add(RfcConfigParameters.User, "600")
        End If

        Return parms

    End Function

End Class



using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SAP.Middleware.Connector;

namespace SAP_Connect_CSharp
{
    class SAPSystemConnect:IDestinationConfiguration
    {
        public bool ChangeEventsSupported()
        {
            throw new NotImplementedException();
        }

        public event RfcDestinationManager.ConfigurationChangeHandler ConfigurationChanged;

        public RfcConfigParameters GetParameters (string destinationName)
        {
            RfcConfigParameters parms = new RfcConfigParameters();
            if ("Dev".Equals(destinationName))
            {
                parms.Add(RfcConfigParameters.AppServerHost, "000.000.000.000");
                parms.Add(RfcConfigParameters.SystemNumber, "95");
                parms.Add(RfcConfigParameters.User, "sap_user");
                parms.Add(RfcConfigParameters.Password, "xxxxxxxxxx");
                parms.Add(RfcConfigParameters.User, "10");
                parms.Add(RfcConfigParameters.User, "EN");
                parms.Add(RfcConfigParameters.User, "5");
                parms.Add(RfcConfigParameters.User, "10");
                parms.Add(RfcConfigParameters.User, "600");
            }

            return parms;

        }

    }
}

I would have to think that you are not implementing all the items in the interface.

I should have mentioned that I also get the following two errors
Error      4      Class 'SAPSystemConnect' must implement 'Function ChangeEventsSupported() As Boolean' for interface 'SAP.Middleware.Connector.IDestinationConfiguration'.
Error      5      Class 'SAPSystemConnect' must implement 'Function GetParameters(destinationName As String) As RfcConfigParameters' for interface 'SAP.Middleware.Connector.IDestinationConfiguration'.

those are the methods you need to implement to get rid of the errors- if you are using visual studio and you click on the interface name there should be a blue box that appears underneath the first letter... if you click that it will give you options to implement and stub in the methods for you.

VB uses a different syntax to declare implementations:

Public Event ConfigurationChanged(destinationName As String, args As Object) Implements SAP.Middleware.Connector.IDestinationConfiguration

Thanks James. How would the entire piece of code look with your changes? I can't seem to get it right
I tried the following and got a "Type expected" error on "SAP.Middleware.Connector.IDestinationConfiguration"

Public Class SAPSystemConnect

    Public Function ChangeEventsSupported() As Boolean
        Throw New NotImplementedException()
    End Function

    Public Event ConfigurationChanged(destinationName As String, args As Object) Implements SAP.Middleware.Connector.IDestinationConfiguration

    Public Function GetParameters(destinationName As String) As RfcConfigParameters
        Dim parms As New RfcConfigParameters()
        If "Dev".Equals(destinationName) Then
            parms.Add(RfcConfigParameters.AppServerHost, "000.000.000.000")
            parms.Add(RfcConfigParameters.SystemNumber, "95")
            parms.Add(RfcConfigParameters.User, "sap_user")
            parms.Add(RfcConfigParameters.Password, "xxxxxxxxxx")
            parms.Add(RfcConfigParameters.User, "10")
            parms.Add(RfcConfigParameters.User, "EN")
            parms.Add(RfcConfigParameters.User, "5")
            parms.Add(RfcConfigParameters.User, "10")
            parms.Add(RfcConfigParameters.User, "600")
        End If

        Return parms

    End Function

End Class
