Thanks for the reply.
I want to continuously capture what all applications are running on the system along with their users.
1) I am running a Mozilla FF, so I want to capture that I am using Mozilla & accessing the www.xyz.com URL.
2) I am writing in a word file, so I want to capture that I am using MS-Word & writing in XYZ.doc.
OS - Currently I am planning to start with Windows but yes I want to build this application for other platforms as well - Linux, Mac.
I understand that there will be different ways of capturing the required information for different platforms.
Please guide me from where to start
