I would STRONGLY recommend that you NOT disable CTRL+ALT+DELETE. That is a
system wide function that users may need for applications other than yours.
There are certain things that an application shouldn't do, even if it is
possible to do so. This, and changing display resolution, are at the top of
that list. I would not use an app that did either of these things.

I have a excel workbook that is via VBA goes out to various 3rd party
applications and gets data from them. The problem I have is that this is
not
instantaneous and even tough I have a progress bar showing things moving
along the user will hit CTRL+ALT+DEL and end the task. This is not a
problem
for excel, but the other software applications seem to be getting "hung
up"
b/c the data transfer is not complete. Is there a way when this workbook
is
opened to disable the CTRL+ALT+DEL function?

I have tried using:
Application.OnKey "^%{DEL}", "NotAllowed"
but nothing happens.

I have even tried just looking for the CTRL + ALT
Application.OnKey "^%", "NotAllowed"
but with this I get run-time error 1004

and if I change it to
Application.OnKey "^{%}", "NotAllowed"
or
Application.OnKey "%{^}", "NotAllowed"
nothing happens
