System control keys handling from BCB4 project

Hi!

Anybody can say me how I can handle system control keys:
 Alt-F4 - close application,
 Ctrl-C - copy to Clipboard,
 etc.
from my BCB4 project form?
For example, I would like to disable Ctrl-C handling.. How I can reach it?

Thanks,
 kooper.

For disable Alt + F4 set Variable CanClose to false in event OnCloseQuery
For disable some other keystroke
try adding a hidden menu item that handles that keystroke - and let the
menu item do exactly nothing.
I hope, it helps. Alex
