Dockable App Bar

i want to make a dockable application bar,
meaning to make a form that will be always on top, and will also
be on the top part of the screen, reducing the usable part of the screen.

'use following code to make/keep a form on top :

Public Const SWP_NOMOVE = &H2
Public Const SWP_NOSIZE = &H1
Public Const FLAGS = SWP_NOSIZE Or SWP_NOMOVE
Public Const HWND_TOP = 0
Public Const HWND_TOPMOST = -1
Public Const HWND_NOTOPMOST = -2

Declare Function SetWindowPos Lib "user32.dll" _
(ByVal hWnd As Long, _
ByVal hWndInsertAfter As Long, _
ByVal X As Long, ByVal Y As Long, _
ByVal cx As Long, ByVal cy As Long, _
ByVal wFlags As Long) As Long

Declare Function GetPrivateProfileString Lib "kernel32.dll" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long

Public Sub KeepWindowOnTop(handle)
'Keeps the window with handle hWnd on top
Dim result%
result% = SetWindowPos(handle, HWND_TOPMOST, 0, 0, 0, 0, FLAGS)
If result <> 1 Then
MsgBox "keep window on top failed"
End If
End Sub 'KeepWindowOnTop

Public Sub RemoveWindowFromTop(handle)
'Removes the window with handle hWnd from top
Dim result
result = SetWindowPos(handle, HWND_NOTOPMOST, 0, 0, 0, 0, FLAGS)
If result <> 1 Then
MsgBox "remove from top failed"
End If
End Sub


' good luck
