Bueno despues de estar buceando por horas en la web encontre este codigo, a mi me ha funcionado para ocultar mi programa del task... lo pongo aqui por si a alguien le interesa el asunto.
En un modulo Option Explicit Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Public Declare Function EnumChildWindows Lib "user32" (ByVal hWndParent As Long, ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long Public Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long Public Declare Function GetClassName Lib "user32" Alias "GetClassNameA" (ByVal hwnd As Long, ByVal lpClassName As String, ByVal nMaxCount As Long) As Long Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Y en un formulario con dos botones Private Sub Command1_Click() Ocultar Me.hwnd End Sub
Private Sub Command2_Click() Mostrar Me.hwnd End Sub
