Hi

I am trying to figure out how to monitor user input.

I have the user typing in a textbox where I fire a method on the text
changes event but this fires on every letter and it fies mant times if the
user types a long string - I 'd rather just run my method when the user is
done or if user pauses

What is the best way to use a timer or thread to check the textbox to see if
the user is still typing or done ???

Thanks

How long a pause constitutes "done"?

It seems like the easiest thing would be to have a Forms.Timer instance
that you simply reset each time the user types something. If the timer
ever actually expires and raises its event, then you do your processing.

The shorter your interval for the timer, the more likely you'll run into
situations where the user wasn't really done but you ran the processing
anyway. You'll have to balance that issue (corrected by lengthening the
timer) with the need to run the processing without excessive delay (if
that's a need you have).

Would you be able to use the textbox's Validating event? This event is fired
when the textbox loses focus. If you need to run your method when the user
pauses, however, Peter's solution sounds much better.
