I have a Windows service that I created that simply exposes a single public
function (RemoteCall). How can I access this publicly exposed method of a
windows service from a windows application? I'm using this as an example to
expand to other more useful methods such as datasets etc. from the service.
I will provide the service code. If someone could provide the client code I
would be grateful.
Windows Service Code:
Imports System.ServiceProcess
Imports System.Runtime.Remoting
Imports System.IO
Imports System.Runtime.Remoting.Channels.Tcp
Imports System.Runtime.Serialization.Formatters.Binary
Public Class Service1
Inherits System.ServiceProcess.ServiceBase
#Region " Component Designer generated code "
Public Sub New()
MyBase.New()
' This call is required by the Component Designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call
End Sub
'UserService overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
' The main entry point for the process
<MTAThread()> _
Shared Sub Main()
Dim ServicesToRun() As System.ServiceProcess.ServiceBase
' More than one NT Service may run within the same process. To add
' another service to this process, change the following line to
' create a second service object. For example,
'
' ServicesToRun = New System.ServiceProcess.ServiceBase () {New
Service1, New MySecondUserService}
'
ServicesToRun = New System.ServiceProcess.ServiceBase() {New
Service1}
System.ServiceProcess.ServiceBase.Run(ServicesToRu n)
End Sub
'Required by the Component Designer
Private components As System.ComponentModel.IContainer
' NOTE: The following procedure is required by the Component Designer
' It can be modified using the Component Designer.
' Do not modify it using the code editor.
Friend WithEvents SqlConnection1 As System.Data.SqlClient.SqlConnection
<System.Diagnostics.DebuggerStepThrough()> Private Sub
InitializeComponent()
End Sub
#End Region
Protected Overrides Sub OnStart(ByVal args() As String)
Dim chan As New TcpChannel(8085)
Dim remotingObj As RemotingObj
Dim RemotingConfiguration As RemotingConfiguration
Dim ChannelServices As Channels.ChannelServices
Try
ChannelServices.RegisterChannel(chan)
RemotingConfiguration.RegisterWellKnownServiceType (GetType
(RemotingObj), "RemotingObj", WellKnownObjectMode.SingleCall)
Catch
System.Diagnostics.EventLog.WriteEntry("ERROR: Failed to
register well known service type ", _
Err.Description, EventLogEntryType.Error)
End Try
End Sub
Protected Overrides Sub OnStop()
' Add code here to perform any tear-down necessary to stop your
service.
End Sub
End Class
Public Class RemotingObj
Inherits System.MarshalByRefObject
Public Function RemoteCall(ByVal name As String)
RemoteCall = "I heard You"
End Function
End Class
