Create an .dll file with this code, call it by inserting a code in the code cave of your app, work in all the files that I develope to sell when I need to lock the sequence crtl+alt+del.
*you don't need admin previlegies to run it
**translate this code to the language that you used in your app

This isn't real solution to disable ctrl+alt+del keys but only hidden the "taskmgr.exe" from shown. This will only affect on xp but not on w7 when the ctrl+alt+del key was pressed.

Alternate way just like your code do, you can also do this:

Open "C:\Windows\System32\Taskmgr.exe" For Input Lock Read Write As #1
