Hello all,
I am trying to develop an application which will run as a windows
service.
The application should have Normal options available with service
like start, stop and pause but along with this I need an option to
show the windows application which
my service has started as a result of its invokation.
So I have written a service control by adding a new project of type
Windows Service
below is the sample code for the class which I have written for the
service to start and work.
Public Class FirstWindowsService
Public Sub New()
' This call is required by the Windows Form Designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
End Sub
Protected Overrides Sub OnStart(ByVal args() As String)
Me.Timer1.Enabled = True
'I have added a ProcessControl which .NET provides to execute
the process which
'I want to run as a service .
'So now in my case it is the windows application which I want
to execute.
Process1.Start()
Me.LogMessage("Service started")
End Sub
Protected Overrides Sub OnStop()
Me.Timer1.Enabled = False
Me.LogMessage("Service stoped")
Try
If Not (Process1.HasExited) Then
Process1.Kill()
End If
Catch ex As Exception
Debug.WriteLine(ex.Message)
End Try
End Sub
Protected Overrides Sub OnPause()
MyBase.OnPause()
Me.Timer1.Enabled = False
Me.LogMessage("Service Paused")
End Sub
Public Sub LogMessage(ByVal message As String)
Dim connection As SqlConnection = Nothing
Try
connection = New
SqlConnection("Server=LocalHost;Database=master;Us er
Id=sa;password=;")
Dim command As SqlCommand = New SqlCommand("INSERT INTO
MyServiceLog (vc_Status, dt_Created) VALUES ('" + message +
"',getdate())", connection)
connection.Open()
Dim totalRows = command.ExecuteNonQuery
Catch ex As Exception
Debug.WriteLine(ex.Message)
Finally
connection.Close()
End Try
End Sub
End Class
Now I have created a windows application which could provide me the
notifyIcon where I can put in my menus for start,stop,pause and View
the application.
below is the sample code for the class which I have written for
making this to work
'This pauses service
Private Sub PauseToolStripMenuItem_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
PauseToolStripMenuItem.Click
Try
ServiceController1.Pause()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
'This Continues paused service
Private Sub ContinueMenuItem_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles ContinueMenuItem.Click
Try
ServiceController1.Continue()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
'This Stops service
Private Sub StopToolStripMenuItem_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
StopToolStripMenuItem.Click
Try
ServiceController1.Stop()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
'Enable disable proper menus
Private Sub ContextMenuStrip1_Opening(ByVal sender As
System.Object, ByVal e As System.ComponentModel.CancelEventArgs)
Handles ContextMenuStrip1.Opening
ServiceController1.Refresh()
Try
Select Case ServiceController1.Status
Case ServiceControllerStatus.Paused
StartToolStripMenuItem.Enabled = False
PauseToolStripMenuItem.Enabled = False
StopToolStripMenuItem.Enabled = False
ContinueMenuItem.Enabled = True
Case ServiceControllerStatus.Running
StartToolStripMenuItem.Enabled = False
ContinueMenuItem.Enabled = False
PauseToolStripMenuItem.Enabled = True
StopToolStripMenuItem.Enabled = True
Case ServiceControllerStatus.Stopped
StartToolStripMenuItem.Enabled = True
PauseToolStripMenuItem.Enabled = False
ContinueMenuItem.Enabled = False
StopToolStripMenuItem.Enabled = False
Case ServiceControllerStatus.StopPending,
ServiceControllerStatus.StartPending _
, ServiceControllerStatus.PausePending,
ServiceControllerStatus.ContinuePending
StartToolStripMenuItem.Enabled = False
PauseToolStripMenuItem.Enabled = False
ContinueMenuItem.Enabled = False
StopToolStripMenuItem.Enabled = False
End Select
Catch ex As Exception
MsgBox(ex.Message)
End Try
ServiceController1.Refresh()
End Sub
I need help on how to make the application to interact with desktop. I
want to show the
application of my service when a ViewToolStripMenuItem is clicked to
show the application.
I have tried some code which manipulates the registry contents in
order to make the application to interact with desktop. It sets the
proper values but won't lauch application
What should I do?
below is the link which I have used for this is there any other
alternative?
