20.2.3 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
'''
''' Instantiate the SmartServer Web service for .NET 3.0 and 3.5 (NOT 2.0)
'''
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
'''
''' Close the SmartServer Web service
'''
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
