>I have a TextBox on a form where I am trying to stuff a message. The message seems to stop after 255 characters. In looking at the help, it says that if MaxLength=0, then there is no limit. Does this really mean no limit, up to 255 characters?

Probably, the max field length is 255 characters, so it kindof makes sense. Use an Edit box instead, 255 in a textbox would be very hard to use anyway.
