This is not necessarily as simple as it may seem, a text file may be opened for reading without placing a lock on the file. The best thing to do is basically attempt to place a lock on the file of the type that you require:

On Error Resume Next
Open "MyFile.txt" For Binary Access Write As #1
If Err.Number <> 0 Then
  Msgbox "Error locking file"
Else
  Close #1
End If

This will basically attempt to open the file for binary write. If it succeeds then you can be fairly certain that the file is not locked by any other user.
