Start button and screen saver help needed...

Alright, I have 2 questions for you all:

1) I want to make it so when my program loads the window's start button is unuseable. I mean I want it so the user can't click it... How can I go about doing that?

2) I want it so the screen saver will not go on while my program is on. How can I do that?

Thanks for help in advance. Later,

Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Public Declare Function EnableWindow Lib "user32" (ByVal hwnd As Long, ByVal fEnable As Long) As Long
 
 
Private Sub Form_Load()
Dim h As Long
h = FindWindowEx(FindWindow("SHell_TRAYWND", vbNullString), ByVal 0&, "BUtton", vbNullString)
EnableWindow h, 0
