Q: Iwould like to disable a checkBox from focusing,so that even user tabbed to orclicked on that checkBox,the checkBox still would not accept the focus,andthe focus remains where it prevIoUsly is.

Possible? Thanks...

A1: Ifyou want to skip the control while tabbing,use control's TabStop property andset it to false. Still,if clicked with mouse,it will still get focus. If youwant to disable the checkBox,set it's Enabled property to false. And in caseyou don't want to disable the checkBox but still don't want it to take focus,use it's GotFocus event to set Focus to any else control.

A2: ActuallyI would like to prevent prevIoUsly focused control to issue lost-focus event.

But,that seems impossible. So,I wouldlike to try different approach to solve the problem.

Anyway,thank you all.
