Hard problem. how to track which application a user opens next?

Question

Hello,
When the user runs my program,
then **with his permission**, I want to be able to track
which application the user has opened.
For example, if he opens resume.rtf in MSWord, then I
should be able to record or store the full path of
MSWord and also the document path (c:\my
documents\resume.rtf).
Do you know how to do it?
I would appreciate any help.
thanks,
Anil Philip

Da Wanderer has posted code (in Visual Basic?) to open a folder. He says it is cross platform. I am stumped by the code for Linux. Does anyone know if it will work for Linux. ie. Can I use the same options to open a document in Linux?
I plan to use Runtime.exec similarly in Java, to open a doc.
if (vars.Contains("GNOME_DESKTOP_SESSION_ID"))
               processes.Add( new ProcessAndArgs("nautilus", "--nodesktop --browser " + path) );
               osFound = true;
          else if (vars.Contains("KDEDIR"))
               processes.Add( new ProcessAndArgs("kfmclient", "exec " + path) );
               osFound = true;
          }
