MAXIMISE windows.

When you maximise windows they do not take up the entire screen, they leave a small gap at the bottom for the taskbar. How can you change this. I have seen it somewhere, setting the area of the desktop that maximised windows occupy. Any ideas?
-Thanks
:) :) :)

Code:

---

'Give you full screen without have to hide taskbar

Private Declare Function SetWindowPos Lib "user32" _
(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

Private Declare Function GetSystemMetrics Lib "user32" _
(ByVal nIndex As Long) As Long
Const SM_CXSCREEN = 0
Const SM_CYSCREEN = 1
Const HWND_TOP = 0
Const SWP_SHOWWINDOW = &H40

Private Sub Command1_Click()
Dim cx As Long
Dim cy As Long
Dim RetVal As Long
' Determine if screen is already maximized.
If Me.WindowState = vbMaximized Then
' Set window to normal size
Me.WindowState = vbNormal
End If ' Get full screen width.
cx = GetSystemMetrics(SM_CXSCREEN) ' Get full screen height.
cy = GetSystemMetrics(SM_CYSCREEN)
' Call API to set new size of window.
RetVal = SetWindowPos(Me.hwnd, HWND_TOP, 0, 0, cx, cy, SWP_SHOWWINDOW)
End Sub
