I am using the FileSystemWatcher and think that I need to use invoke on the
code below:

Private Sub dirMon_InformationMessageEvent(ByVal InformationMessage As String)
Me.txtActivity.Text = (InformationMessage & Me.txtActivity.Text)
End Sub

The program fails when I am trying to update the textbox as shown so that
the user can see the progress. Is there an easy way that I can use Invoke
and pass the InformationMessage variable, as this contains the message for
the user to see.

Here is how I set up the event handler which goes with the code from the
previous post:

'Set up the handler for the "InformationMessageEvent" event.
'This will enable the application to receive messages from the directory
object.
AddHandler _dirMon.infoMessageEvent, New
DirectoryMirror.infoMessageDelegate(AddressOf dirMon_InformationMessageEvent)
