I am developing a POS, this use a keyboard and a barcode for entries. I want this to be a full proof secure by preventing the user not to go to windows environment or accidentally go to windows. how can i
1.Disable the <alt> + <tab>
2.Disable the <Ctrl> + <Alt> + <Del>
3.Disable the <Ctrl> + <Esc>
4.Disable the <Ctrl> + <Shift> + <Esc>
5.Disable the SCREENSAVER/AUTOPOWER OFF (MONITOR)
6.SOME keys on the keyboard
7.Or anything you can think of to disable as long as the user will not go to the windows environment. Only my POS should be on focus and on TOP of all other applications.
I'm using Delphi 7 under Windows XP operating system.
Thank you in advance.
