Check If Extender Is Already Loaded
Keywords: Check Determine AddExtender Extender Loaded
You can't attempt to load more than 10 extenders even if you are attempting to load an already loaded extender. The AddExtender function will error if you attempt to load an eleventh extender while ten extenders are currently loaded, even if the eleventh extender is an already loaded extender.
