1、首先应该把以下声明放再窗体的声明部分：
Const SWP_NOSIZE = &H1
Const SWP_NOMOVE = &H2
Const SWP_NOACTIVATE = &H10
Const HWND_TOPMOST = -1
Const HWND_NOTOPMOST = -2
Const SWP_SHOWWINDOW = &H40
Private Declare Function SetWindowPos Lib _
"user32" Alias "SetWindowPos" (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
2.使窗口Always On Top时，可以用下面的语句：
SetWindowPos hWnd, HWND_TOPMOST, 0, 0, 0, 0, _
SWP_NOACTIVATE Or SWP_SHOWWINDOW Or SWP_NOMOVE _
Or SWP_NOSIZE
3.使窗口取消Always On Top功能，用下面的语句：
SetWindowPos hWnd, HWND_NOTOPMOST, 0, 0, 0, 0, _
SWP_NOACTIVATE Or SWP_SHOWWINDOW Or SWP_NOMOVE _
Or SWP_NOSIZE |
