Keep user from ctl+alt+del to kill app 2

[jadams0173]

I've read on this forum that disabling or circumventing the ctl+alt+del keys is anything from VERY dangerous to not possible. So how do you keep a user from killing an app this way? I have an app that the users are killing this way instead of entering the data.

I have looked into ways to make it not show up in the task list but have been unsuccessful at this. Any suggestions?

No. We do it on Honeywell PlantScape/Experion PKS.

strongm,
was that a sigh of frustration or aggrevation? I tried the app.taskvisible and it didn't work.

I think it was a sigh of frustation....sorry....

TaskVisible Property

In Visual Basic 6.0, the TaskVisible property of the App object determines whether an application appears in the Windows Task List (Windows 9x) or the Task Manager Applications tab (Windows 2000 or later). The property is commonly used to prevent a user from closing an application that was designed to run as a background task. In most cases, the TaskVisible property is used with applications that do not display user interfaces.

Frustration about a number of issues, to be honest. TaskVisible was just one of them ...

Maybe I should be more explicit

1) In the VB IDE, try pressing F1 with TaskVisible highlighted. The help file is pretty explicit

2) Do some serious research on whether the Task Manager is what we always expect to appear when we press CAD

3) Realise that ancient W95 screensaver hacks are unlikely to be relavant on a modern Windows OS

4) Trust thos people who say that trapping/deactivating CAD isn't possible in VB (amongst the info in this thread are two solutions that, to my knowledge, actually work; however, neither can be achieved in VB, and at least one of them can potentially render your machine unuseable if you get your (non-VB) code wrong - although this may be less of a problem in these days of virtual OS installations)

Thanks for the info strongm. I will do as you suggested and do my homework before I try to do anything.

A tipster with 1000+ stars can't be all wrong! Just a little humor. Thanks for all that you do in the forums!!
