actually, no. somebody _else_ could also listen for the OnCreate or whatever event and retain a hard reference. you cannot know whether this happens. if it happens, that hard reference will keep the disposed instance alive. so, the fact that a WeakReference can be converted to a hard reference is no guarantee that the instance has not been disposed. > regards, michael -- "Debugging is twice as hard as writing the code in the first place.
