>I have a field which I need to accept the double click but when the user does a single click or presses a key, the focus should not appear on the field. What is the best approach to do that?

In the GotFocus event: set cursor off. In DoubleClick event set cursor on in LostFocus event set cursor on. Is it enough? If not, you may try to move focus to another control, but this way, DoubleClick would not work too.
