[求助]如何使form直接显示在桌面上，并“总在最前面”？

求助：

各位老师：

如何使Word的表单直接显示在桌面上，并“总在最前面”，即象某些媒体播放器软件一样，窗口总在最前面，其他程序的窗口不会遮盖它，需要使用ＡＰＩ完成么？我对ＡＰＩ不太懂，也未找到相应的功能，请帮助我。

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
    (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

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_NOSIZE = &H1

Private Sub UserForm_Activate()
    Dim hwnd As Long
    hwnd = FindWindow("ThunderDFrame", vbNullString)
    SetWindowPos hwnd, HWND_TOPMOST, Me.Left + Me.Width / 2, Me.Top + Me.Height / 2, 0, 0, SWP_NOSIZE
End Sub
