Binaryworld - Hide or disable the Windows' application bar ... [ VB -> Windows ]

The Windows' application bar (or Startbar) is a window like any other window in the system, so you can hide/show and enable/disable it. The only thing you need to know is that that the class name of the Start bar window is "Shell_TrayWnd" and that its window name is a null string. Here is the code that lets you do the trick:

Click here to copy the following block

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal _
  lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, _
  ByVal nCmdShow As Long) As Long
Private Declare Function EnableWindow Lib "user32" (ByVal hwnd As Long, _
  ByVal fEnable As Long) As Long
Private Const SW_HIDE = 0
Private Const SW_SHOW = 5

Sub ShowStartBar(ByVal bVisible As Boolean)
  Dim hWnd_StartBar As Long
  hWnd_StartBar = FindWindow("Shell_TrayWnd", "")
  If bVisible Then
    ShowWindow hWnd_StartBar, SW_SHOW
  Else
    ShowWindow hWnd_StartBar, SW_HIDE
  End If
End Sub

Sub EnableStartBar(ByVal bEnable As Boolean)
  Dim hWnd_StartBar As Long
  hWnd_StartBar = FindWindow("Shell_TrayWnd", "")
  If bEnable Then
    EnableWindow hWnd_StartBar, True
  Else
    EnableWindow hWnd_StartBar, False
  End If
End Sub

If you like concise code you can rewrite the above procedures as follows:

Click here to copy the following block

Sub ShowStartBar(ByVal bVisible As Boolean)
ShowWindow FindWindow("Shell_TrayWnd", ""), IIf(bVisible, SW_SHOW, SW_HIDE)
End Sub

Sub EnableStartBar(ByVal bEnable As Boolean)
EnableWindow FindWindow("Shell_TrayWnd", ""), bEnable
End Sub
