Dear Experts,
I am working on a project for Cyber Cafe on VB.Net. I am unable to give the facility for storing how much data downloaded and uploaded during net surfing on a particular computer.

i went on link and gotted more codes but all of them was not up to the mark because i need code for recording file size dowload and upload during net surfing whether surfing in firefox,ie8,chrome etc. i.e. our code will run and keep the history of only files download and upload (It will be limited for 20 MB if DL/UL exceed 20 MB only DL(Downloading/UL(Uploading) should be blocked automatically)
