To create the functions and to see how they work, follow these steps:
  1. Press ALT+F11 to start the Visual Basic Editor (or in Microsoft Access, open a database.)
  2. Type the following code in a new module:
          Option Compare Database  ' In Microsoft Access only.      Option Explicit      Dim handleW1 As Long      Private Declare Function FindWindowA Lib "user32" _      (ByVal lpClassName As String, _      ByVal lpWindowName As String) As Long      Private Declare Function SetWindowPos Lib "user32" _      (ByVal handleW1 As Long, _      ByVal handleW1InsertWhere As Long, ByVal w As Long, _      ByVal x As Long, ByVal y As Long, ByVal z As Long, _      ByVal wFlags As Long) As Long      Const TOGGLE_HIDEWINDOW = &H80      Const TOGGLE_UNHIDEWINDOW = &H40      Function HideTaskbar()         handleW1 = FindWindowA("Shell_traywnd", "")         Call SetWindowPos(handleW1, 0, 0, 0, _         0, 0, TOGGLE_HIDEWINDOW)      End Function      Function UnhideTaskbar()         Call SetWindowPos(handleW1, 0, 0, 0, _         0, 0, TOGGLE_UNHIDEWINDOW)      End Function
