i want to make form like the ctrl+alt+del close program form

How about I give you some tips, and you write the code yourself?

You're going to need to do a little tinkering with API, so I suggest you look through the Topic Areas of VB-World and find the example the retrieves a list of all the available windows. Next, you're going to need to get the process of the handle you want to terminate and kill it, I think there's an example of that around here somewhere too.

...do your own work.
