I originally stole this code from Microsoft. Check out the KB article clifABB cited as well. Note that this does not work if you run from the VB environment, you will have to compile an EXE and run it.
Put this in a module:
'---------- start of module code.
Option Explicit
Public Const SWP_NOMOVE = 2
Public Const SWP_NOSIZE = 1
Public Const FLAGS = SWP_NOMOVE Or SWP_NOSIZE
Public Const HWND_TOPMOST = -1
Public Const HWND_NOTOPMOST = -2


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

Public Function SetTopMostWindow(hwnd As Long, Topmost As Boolean) _
   As Long

   If Topmost = True Then 'Make the window topmost
      SetTopMostWindow = SetWindowPos(hwnd, HWND_TOPMOST, 0, 0, 0, _
         0, FLAGS)
   Else
      SetTopMostWindow = SetWindowPos(hwnd, HWND_NOTOPMOST, 0, 0, _
         0, 0, FLAGS)
      SetTopMostWindow = False
   End If
End Function
'--------- End of module code

To set a window to always on top:
    Dim lR As Long
    lR = SetTopMostWindow(Form1.hwnd, True)

To remove always on top:
    Dim lR As Long
    lR = SetTopMostWindow(Form1.hwnd, False)
