maybe you could use the last modified value, Windows will store the date the last time a file was modified... or you could try matching the File Size, if the file is larger than it was before then new content has been added... etc...

hope this helps

You could set up a timer and scan every (60 or whatever) seconds if the 'modification date' has changed or the file size. And if changed process the file..

It works for me ...

Test it...

Place a timer and a textbox on your form and test it...

Dim FirstTime As Boolean
Private Sub Form_Load()
FirstTime = False
Timer1.Interval = 1000 '1 second
End Sub
Private Sub Text1_Change()
If FirstTime = True Then
MsgBox Text1
End If
End Sub
Private Sub Timer1_Timer()
    Text1 = FileDateTime("c:\test.txt")
    FirstTime = True
End Sub
