Make the window permanently on top

How do I make the window of my application stays on top of the screen permanently even though other application launch later ?
Thanks.

SetWindowPos API. Post this code into a form:

VB Code:

Option Explicit
 
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 Const HWND_TOPMOST = -1
Private Const SWP_NOMOVE = &H2
Private Const SWP_NOSIZE = &H1
Private Const SWP_STAY_AS_IS = SWP_NOMOVE Or SWP_NOSIZE
 
 
Private Sub Form_Load()
    SetWindowPos Me.hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_STAY_AS_IS
End Sub
