keyboard enable/disable

HELLO,
I AM WORKING ON A REAL TIME ON LINE APPLICATION. I WOULD LIKE MY APPLICATION
TO DISABLE THE KEYBOARD ON STARTING THE APPLICATION AND ENABLE IT JUST
BEFORE THE APPLICATION QUITS.

AWAITING FOR YOUR HELP IN THIS REGARD.
THANKING YOU IN ADVANCE.
GAYATHRI.

The keyboard is a system resource and your process can't disable it. Windows doesn't work this way. Perhaps you can remove the keyboard ?
