Hi All

I try to build a system that monitors xls files. how is it possible to
notice if someone cloeses an excel file?is there an event i can connect on or
something? (i will develop the system with visual studio .net c#)
aditionally i know what the filename is and i also know what the userid is.

if someone could show me an example that would be nice.

thanks for your help
