  • It's a long story.but basically i dont want any student to get out of our locked in browser while he is taking the exam using a combination like Ctrl + Alt + Del to run a taskmgr – m7md Sep 15 '14 at 18:52

  • @m7md sounds like an IT problem, not a web problem. – MikeSmithDev Sep 15 '14 at 19:10
  • I'm confused if it is even possible. cause all links u guys put is talking about issues not necessarily related to web application – m7md Sep 15 '14 at 19:16
  • @m7md, The answer is: It's not possible. Even with `ActiveX` for a web application, you can't prevent Ctrl + Alt + Del combination within a web application. – user2711965 Sep 15 '14 at 19:23

It is not possible. Web applications will run in client's browser. You can't disable Alt key on client's machine.
