Instantiating the Web Service Client in Visual Basic .NET 3.5

The following example shows how to instantiate the Web service in Visual Basic. NET:

Imports System

Imports System.Collections.Generic

Imports System.Linq

Imports System.Text

Imports System.ServiceModel 'make sure you add this statement to iLON_SoapCalls class

Public Class iLON_SoapCalls

'your SmartServer’s IpAddress

Public _iLonEndpointIpAddress As String = "<SmartServer IP address>"

'your SmartServer’s Web service reference

Public _iLON As iLON_SmartServer.iLON100portTypeClient = Nothing

''' <summary>

''' Instantiate the SmartServer Web service for .NET 3.0 and 3.5 (NOT 2.0)

''' </summary>

Public Sub BindClientToSmartServer()

' Specify the binding to be used for the client.

Dim binding As BasicHttpBinding = New BasicHttpBinding()

' Initialize the namespace

binding.Namespace = "http:'wsdl.echelon.com/web_services_ns/ilon100/v4.0/message/"

' Obtain the URL of the Web service on the i.LON SmartServer.

Dim endpointAddress As System.ServiceModel.EndpointAddress =

New System.ServiceModel.EndpointAddress("http://" + _iLonEndpointIpAddress + "/WSDL/iLON100.wsdl")

' Instantiate the SmartServer Web service object with this address and binding.

_iLON = New iLON_SmartServer.iLON100portTypeClient(binding, endpointAddress)

' uncomment the lines below to enable authentication

' binding.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.TransportCredentialOnly

' binding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Basic

' _iLON.ChannelFactory.Credentials.UserName.UserName = "ilon"

' _iLON.ChannelFactory.Credentials.UserName.Password = "ilon"

End Sub

''' <summary>

''' Close the SmartServer Web service

''' </summary>

Public

Sub CloseBindingToSmartServer()

' Closing the client gracefully

' closes the connection and cleans up resources

Try

_iLON.Close()

Finally

_iLON = Nothing

End Try

End Sub

End Class
