Anytime you want to create a 'custom' event, that VFP doesn't give you, you can usuallyuse a timer that fires every so often (half a second?) that checks the status of the value you are looking for. You would need to define a form property or something that stores the old value, and set it every time after you check. When the actual value is different from the stored value, your 'event' has been fired. HTH
