Hi,
Do you know if there is a component in which I can write the data into, that

Currently I am writing to a rich text box.

Once again, thank you,
Celia

Look in your ASCI table and determine what the EOF character is then search 
for it - if you're going to do it that way rather than the way Tyler does 
it.
