vb.net how to start a folder monitor service at runtime and pass on the folder path to monitor?
- by mazrabul
hi,
I have the following windows service file:
Imports System.ServiceProcess
Imports System.IO
Public Class fswService
Dim fsw As FileSystemWatcher
Dim lf As StreamWriter
Protected Overrides Sub OnStart(ByVal args As String())
' Add code here to start your service. This method should set things
' in motion so your service can do its work.
lf = New StreamWriter(Application.StartupPath & "\fsw_lg.log")
fsw = New FileSystemWatcher()
fsw.Path = args(0)
fsw.IncludeSubdirectories = True
fsw.Filter = ".txt"
fsw.EnableRaisingEvents = True
AddHandler fsw.Created, New FileSystemEventHandler(AddressOf file_created)
AddHandler fsw.Changed, New FileSystemEventHandler(AddressOf file_changed)
AddHandler fsw.Deleted, New FileSystemEventHandler(AddressOf file_deleted)
End Sub
Public Sub file_created(ByVal obj As Object, ByVal e As FileSystemEventArgs)
lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-created")
End Sub
Public Sub file_changed(ByVal obj As Object, ByVal e As FileSystemEventArgs)
lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-changed")
End Sub
Public Sub file_deleted(ByVal obj As Object, ByVal e As FileSystemEventArgs)
lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-deleted")
End Sub
Protected Overrides Sub OnStop()
lf.Close()
End Sub
End Class
i have the ServiceName set to fswService (same as class name). When I added an installer I also set the ServiceName for the ServiceInstaller1 as fswService.
I want to start this service at runtime based on the user setting the path of the folder to be watched. To achieve this I have the following:
Dim fsw_controller As New ServiceProcess.ServiceController
fsw_controller.Start(fswService)
2 problems: first, intellisense error saying: 'fswService' is a type and cannot be used as an expression. second, I can not figure out a way to pass on to the service the path of the folder to watch (which is stored at My.Settings.userPath).
I really thought this is how you start a service. Am I missing something?
Your help is, as always, appreciated.
Thanks
