System.IO.FileSystemWatcher

System.IO.FileSystemWatcher

When a user copies and pastes a file from one directory to a directory that is monitored
by the FileSystemWatcher, the FileSystemWatcher executes twice, once for a CREATED file
event and once for a CHANGED file event.

I think I understand why. First the monitored file is created and then contents are
inserted into it. (Although the file datetime remains the same.)

This is not what I require. If there is a new file created in a monitored directoy, I
only want TRUELY CREATED event raised, not the default of CREATED event raised & CHANGED
event raised.

Is there anyway I can turn-off the second event (CHANGED event raise) ?

Thanks

Hi this is a bug from Microsoft in this Obj

''' <remarks>Implementing a trick to stop double call from the onChange
FileSystemWatcher event bug</remarks>
Protected Sub OnChanged(ByVal source As Object, ByVal e As
FileSystemEventArgs)
Try

If lastChange <>
TimeSpan.FromTicks(Now.Ticks).TotalMilliseconds Then
'DO YOUR STUFF HERE
End If

lastChange =
TimeSpan.FromTicks(Now.Ticks).TotalMilliseconds

Catch ex As Exception
errorHandler(ex, Me.GetType.ToString & ".onChanged")

Finally
End Try

End Sub

Hope this help

Thanks!!! I'll play with this and let everyone know the outcome. This double call is
an interesting feature from MS.
