Answer 1

模块的代码Public 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 '以上为API函数声明
Public Const HWND_TOPMOST = -1
Public Const SWP_NOMOVE = &H2
Public Const SWP_NOSIZE = &H1
Public Const SWP_FRAMECHANGED = &H20
'The frame changed: send WM_NCCALCSIZE
Public Const SWP_DRAWFRAME = SWP_FRAMECHANGED '以上为程序中用到的常量
Public Const HWND_BOTTOM = 1
Public Const HWND_BROADCAST = &HFFFF&
Public Const HWND_DESKTOP = 0
Public Const HWND_NOTOPMOST = -2
Public Const HWND_TOP = 0
Public Const SWP_HIDEWINDOW = &H80
Public Const SWP_NOACTIVATE = &H10
Public Const SWP_NOCOPYBITS = &H100
Public Const SWP_NOOWNERZORDER = &H200
'Don't do owner Z ordering
Public Const SWP_NOREDRAW = &H8
Public Const SWP_NOREPOSITION = SWP_NOOWNERZORDER
Public Const SWP_NOZORDER = &H4
Public Const SWP_SHOWWINDOW = &H40 '以上常量声明在程序中没有使用'可以试着在调用SetWindowPos函数时使用这些常量或它们的组合'得到其他效果
Public Const Flags = SWP_DRAWFRAME Or SWP_NOMOVE Or SWP_NOSIZE
窗口代码Private Sub Form_Load()Dim res As Long
res = SetWindowPos(Me.hwnd, HWND_TOPMOST, 0, 0, 0, 0, Flags)End Sub
