Except that -1 isn't reliable because, as already discussed, it could be a valid data value. I would in fact expect the code returned to vary by OS and device (and that's what RaiseLastOSError is for) but I really didn't expect there to be an OS or device on which an LB_GETITEMDATA request out of the range of the listbox wasn't an error! Evidently I'm too trusting or something. Under the circumstances, checking the bounds first seems necessary.
