I am using the ShowAnalyzer from Dragon Global to detect commercials on live TV (the broadcast is delayed).  Their program outputs to a .edl file which lists the blocks of commercials (in seconds).  The .edl file is constantly being updated and I was wondering what would be the best way to have my VB.Net program read and act upon a new commercial.  Thanks for the help, Ron

You can use the filewatcher object to detect when the file is changed



sub setupwatch
 
        ' Create a new FileSystemWatcher and set its properties.
        Dim watcher As New FileSystemWatcher()
        watcher.Path = yourpath
        ' Watch for changes in LastAccess and LastWrite times, and
        ' the renaming of files or directories. 
        watcher.NotifyFilter = (NotifyFilters.LastWrite)
        ' Only watch text files.
        watcher.Filter = yourfilename
        ' Add event handlers.
        AddHandler watcher.Changed, AddressOf OnChanged
 
        ' Begin watching.
        watcher.EnableRaisingEvents = True
 
    End Sub
 
    ' Define the event handlers.
    Private Shared Sub OnChanged(source As Object, e As FileSystemEventArgs)
        ' Specify what is done when a file is changed
    End Sub
