I\'m developing a vbnet/c#.NET based application that opens files with different applications(excel, word, etc).

There are different approaches for this problem. You can calculate some sort of initial check-sum and see whether your document has any changes by redoing the check-sum and comparing against the original one.

This part is not very clear from your question, If the document gets saved, probably you can look at the date_modified value of the file to see whether there has been any modifications.
