Handling Keystrokes

[Alessio]

Hi All!
I've a problem : Into an application I'm developing, I need to check if a
key (or a key set) is pressed and handle this event.
Well : I can now capture the event "key_is_pressed", but I can't avoid the
event this pression generates.
For Example : If an user on W98 presses the keys CTRL+ALT+Canc I receive
from my application an error status, and I show a dialog like "what do you
do?". So, All seems ok but, after the Dialog has been shown, I can't avoid
the visualization of the task-list window.
How Can I do?

N.B : that's only an example : the same problem was encountered while monitoring
the status of ALT+F4 or CTRL+Esc etc.etc...

Thanx All

Alessio
