monitoring a file

Thanks,
THe code work greate,

But i continue havien a problem

I,m using  the System.IO.FileSystemWatcher() to monituring my folder, when a folder is created and it detected  then I try to turn on my timer but it keep looping inside my logchange sub without entering in my timer.

I atach the code

Private Sub btn_startwatch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_startwatch.Click
watchfolder = New System.IO.FileSystemWatcher()
watchfolder.Path = "C:\"
AddHandler watchfolder.Created, AddressOf logchange
watchfolder.EnableRaisingEvents = True
End Sub

Private Sub logchange(ByVal source As Object, ByVal e As System.IO.FileSystemEventArgs)
If e.ChangeType = IO.WatcherChangeTypes.Created Then
 File = e.FullPath
 Timer1.Enabled = True
End If
End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim FileName As String = File
Try
Dim FS As IO.FileStream = IO.File.Open(FileName, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.None)
FS.Close()
FS.Dispose()
FS = Nothing
Timer1.Enabled = false
Call My Api process
Catch ex As IO.IOException
' FIle is Lock
Catch ex As Exception
'Error
End Try
End Sub

Hi there

A couple of notes.
Seeing that you are attaching the logchange sub to the Created event of watchfolder, there is no need to test again within the sub, the change type is .created as that is the event that fired and being handled

Also look at setting watcher.notifyfilter to relevant events to track
You can also try and invoke the timer.start method to ensure that the timer has started

Hope this helps as I havn't worked with the FSW in a couple of years.

Cheers
