Blocking keyboard buttons STRG+ALT+DEL

[_EMG_]

Hi there,

is there some way in LabVIEW to filter a buttom that is pressed? I need to block the keys STRG+ALT+DEL (Windows task monitor), the VI must keep alway on top, but with this keys the user is able to close it............

Or is there some other way??

Thanks,

Sascha

This functionality is part of the LabVIEW DSC Toolkit. But I believe to remember that doing so has also a few sideeffects which might be not as desirable.

Also, depending on your setup, you can do various things in windows itself to make sure your application is the only one, like disabling the ctrl+alt+del option (although I don't remember where) or by replacing the windows shell with your own application and so on. You should think about how much effort you want to put into this - how likely is anyone to crash the program and what happens if they will?
