指定窗口总处于其他窗口之上

使指定窗口总处于其他窗口之上   
     
将以下代码加入到Form中,这个Form就成为一个在其他所有窗口之上的窗口了.

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

Const HWND_TOPMOST = -1

Private Sub Form_Load()
SetWindowPos Me.hwnd, HWND_TOPMOST, Me.Left / Screen.TwipsPerPixelX _
, Me.Top \ Screen.TwipsPerPixelY, Me.Width \ Screen.TwipsPerPixelX, _
Me.Height \ Screen.TwipsPerPixelY, 0
End Sub
