Hiding Your Program in the Ctrl-Alt-Del list

The easiest method is probably by using the TaskVisible property of the App-object. If you set it to False, the task will be hiden from the CTRL-ALT-DEL-list. If you set it to True, your task will reappear again.
'Hide from list
App.TaskVisible = False
'Show on list
App.TaskVisible = True

Thanks to Fernando Robles for this tip.

There is another, more complicated way to accomplish the same effect.
You can register your program as a service. This is done by passing the process ID of your application to the RegisterService API.

Declarations

Copy the following code into the declarations section of a module:

Public Declare Function GetCurrentProcessId _
Lib "kernel32" () As Long
Public Declare Function GetCurrentProcess _
Lib "kernel32" () As Long
Public Declare Function RegisterServiceProcess _
Lib "kernel32" (ByVal dwProcessID As Long, _
ByVal dwType As Long) As Long

Public Const RSP_SIMPLE_SERVICE = 1
Public Const RSP_UNREGISTER_SERVICE = 0

Procedures

To remove your program from the Ctrl+Alt+Delete list, call the MakeMeService procedure:

Public Sub MakeMeService()
Dim pid As Long
Dim reserv As Long

pid = GetCurrentProcessId()
regserv = RegisterServiceProcess(pid, RSP_SIMPLE_SERVICE)
End Sub

To restore your application to the Ctrl+Alt+Delete list, call the UnMakeMeService procedure:

Public UnMakeMeService()
Dim pid As Long
Dim reserv As Long

pid = GetCurrentProcessId()
regserv = RegisterServiceProcess(pid, _
RSP_UNREGISTER_SERVICE)
'End Code

Don't forget to unregister your application as a service before it closes to free up system resources by calling UnMakeMeService.
