How can I intercept all key events, including ctrl+alt+del and ctrl+tab?

Question

I\'m writing a screen saver type app that needs to stop the user from accessing the system without typing a password. I want to catch/supress the various methods a user migh

As this seems to be a good collection spot for the accrual of various means with which to "intercept" the three key psuedo-break control alt delete, here is something I encountered yesterday that may be of use.

In my opinion, when it seems that the only practical and timely option is to cut the power (i.e. MECHANICAL removal of the battery of an overloaded android-like handheld computer) to halt whatever procession or malfunction results in rather solid and complete ( or long enduring) irresponsiveness-- it appears that a dangerous and frustrating lineage continues--- and continues to get worse.

Especially with the removal of sensible and straightforward things like mechanical speaker volume controls. ( sure, bulky, more material, but of course that is just the thing, what good to an individual or being is infinite and perfect consciousness without a handle on it or it's experience?)

It is a lineage of approaches to designing the -environment that is responsible for the responsiveness to the user- part of a critical and truly meaningful technological interface. ( The only?)

I say put some buttons --direct-to-hardware-control-- back on the things --at least until the software aspects of these technologies become fully adapted to artificial soft interfacing, which I account for in an exhaustive accounting of all heuristical provisionings.

Even in the mechanics of the universe I bet there's a handy reset, restore, suspend, halt type of function(s) for the safety and fundamental viability of the presence of what would constitute as the designer of all that follows the initiating perpetual mystery of existence: INTELLIGENT AWARENESS and WILL.
