Filesystemwatcher triggers multiple events for one file

Question

I'm using a FileSyswtemWatcher and when a new file is created or changed, it shows up as a duplicated event.  If printing to a PDF file in the monitored folder, then 4 events come up...the problem I'm having is mainly with insertions to am SQL database are also duplicated.  has anyone figured out how to supress the additional messages down to just one event?
