When I read the link that fastestindian posted I tried googling the problem. It's quite complicated. It looks like you'll have to create an override for a windows dll. Control+Alt+Del ete is a system level thing and it's not easy to interrupt.

First try this though....

Perhaps you can just disable the task manager?

If that doesn't work, the name of the dll you need to look into creating is called "gina.dll".

Good luck!

I tried it
It doesn't work

You tried the registry setting and it didn't work?

Then you'll have to look into creating your own "gina.dll" I guess.

i don't want to lock key combination. i want to lock alt and control if i lock this then keycombination couldn't not work.

so can you post sample code

No, I can't because I don't know how to do it. This is something you'll have to solve on your own. If we can help, we will, but ultimately it's up to you to do your own work.

Sorry if this comes across as harsh, but the purpose of Bytes isn't to do your job for you, it's to help you to learn to do your job better and become a better developer. Just giving you the answer doesn't serve that purpose.

Please read what was posted above, dive in and give things a try. If you get bogged down, come back with specific questions.

Good luck!
