Need a VB-Script that read a txt-file and only the lines that are new since last time

Hi,

I need help to write a VB script that read all new lines since the last time.

For example:  The script reads the textfile at specific time, then 10 minutes later the script read the file again, and it should now only read the lines that are new since last time. Anyone that has such a script in your scriptingbox?

cheers!
