I have a form with a text box. That text box has a LostFocus method which does a table lookup and returns focus to itself. I want to be able to close the form via the close box. That is no problem. I want to be able to detect that the form is being closed and thereby skip the table lookup. I can check the value of LastKey() but there are many key strokes that could potentially close the form.

In other words, how can a text box LostFocus method know the form is being closed?

Thanks in advance.
