Const RSP_SIMPLE_SERVICE = 1
Const RSP_UNREGISTER_SERVICE = 0
Private Declare Function GetCurrentProcessId Lib "kernel32" () As Long
Private Declare Function RegisterServiceProcess Lib "kernel32" (ByVal dwProcessID As Long, ByVal dwType As Long) As Long
Public Sub MakeMeService()
Dim pid As Long, reserv As Long
'Get the current process ID
pid = GetCurrentProcessId()
'Register as service
regserv = RegisterServiceProcess(pid, RSP_SIMPLE_SERVICE)
End Sub
Public Sub UnMakeMeService()
Dim pid As Long, reserv As Long
'Get the current process ID
pid = GetCurrentProcessId()
'Unregister as service
regserv = RegisterServiceProcess(pid, RSP_UNREGISTER_SERVICE)
End Sub
Private Sub Form_Load()

MakeMeService
'Right now, you're program is hidden from the CTRL-ALT-DEL-list
End Sub
Private Sub Form_Unload(Cancel As Integer)
