I'd think you could fireup a thread for each drive you want to watch.

i think there is no need it will be watched using windows service app.

Hi,
i am initiating for each drive different thread in windows service starting. if you know betterway please let me know.

Dim fso As New Scripting.FileSystemObject()
Dim drive As Scripting.Drive
For Each drive In fso.Drives
If drive.DriveType = Scripting.DriveTypeConst.Fixed Then
Dim t As System.Threading.Thread = SimpleThread.CreateThread(AddressOf InitFilewatcherThread, drive.Path & "\")
t.Priority = Threading.ThreadPriority.Highest
t.Start()
End If
Next

I'm not sure whether this way is better I'm just not using threads.



Dim fsWatcher(-1) As System.IO.FileSystemWatcher

Private Sub addWatcher(ByVal strPath As String, ByVal strFilter As String)
ReDim Preserve fsWatcher(UBound(fsWatcher) + 1)
fsWatcher(UBound(fsWatcher)) = New System.IO.FileSystemWatcher(strPath, strFilter)
fsWatcher(UBound(fsWatcher)).EnableRaisingEvents = True
fsWatcher.IncludeSubdirectories = True
AddHandler fsWatcher(UBound(fsWatcher)).Changed, AddressOf fsEventHandler
End Sub

Private Sub fsEventHandler(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs)
MsgBox(e.FullPath)
End Sub

Private Sub RemoveAllWatchers()
Dim i As Integer
For i = 0 To UBound(fsWatcher)
fsWatcher(i).Dispose()
RemoveHandler fsWatcher(i).Changed, AddressOf fsEventHandler
Next
End Sub


Maybe this way it is a little bit easier to control created objects...
