Virusim,

provided you are already sitting in the VFP READ EVENTS event queue, Use a timer that's set to trigger some time in the future. Then in it's Timer event you can check to see if what you are waiting for has finished or not. If it is carry out the task and let the timer object go out of scope. If it's not finished then let the timer go off again.
