It all depends on the windfows version you are working with, in XP you could modify / create a new GINA.DLL which is the one that handles Ctrl+Alt+Del, or start modifying policies.

Ctrl+alt+Del is a subset of keys that has to be captured in a different way than a normal key set.

Search for samples, but don't expect to be able to do it from your program.

Search for this ctrl+alt+del blocking windows in google.

Good luck.

Try it:

VB

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Timer1.Start()
    End Sub
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    For Each selProcess As Process In Process.GetProcesses
    If selProcess.ProcessName = "taskmgr" Then
    selProcess.Kill()
    Exit For
    End If
    Next
    End Sub
 End Class

or for example you can set the registry key to this value:
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableTaskMgr, i.e.

VB

systemRegistry.SetValue("DisableTaskMgr", 1)

or for example you can write :

VB

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim systemRegistry As RegistryKey = _
Registry.CurrentUser.CreateSubKey("Software\Microsoft\Windows\CurrentVersion\Policies\System")
systemRegistry.SetValue("DisableTaskMgr", 1)
systemRegistry.Close()
End Sub
End Class
