hahaha.. i thought the long scroll bar means I have many people answering my question, but then..

oh, well..

ok..back to the topic... i found this program called IM Lock (www.comvigo.com). it can block/automatically shut down instant messaging, internet browser, games and any other programs.. how did they do this?

let's skip all those reasons why i shouldn't do this.. because on the second thought, as most of u suggested here, it's better for me to just use the windows security function... but just for learning purposes.. and i'm technically curious on how this thing could be done... anyone here knows how to do this?

thanks a lot
