新建立类模块：
Option Explicit
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)
窗口代码：
Dim rtn
'让窗口在顶层
rtn = SetWindowPos(Me.hwnd, -1, 0, 0, 0, 0, 3)
'取消窗口在顶层
'rtn = SetWindowPos(F_V.hwnd, -2, 0, 0, 0, 0, 3)
这个简单啊，引用API函数SetWindowPos就可以解决。下面看看我的代码：
Private Declare Function SetWindowPos Lib "user32.dll" (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 SWP_NOMOVE = H2
Const SWP_NOSIZE = H1
Const FLAG = SWP_NOMOVE Or SWP_NOSIZE
Const HWND_TOPMOST = -1
Const HWND_NOTOPMOST = -2
Const HWND_TOP = 0
Const HWND_BOTTOM = 1
将窗口设置最前：Call SetWindowPos(Me.hwnd, HWND_TOPMOST, 0, 0, 0, 0, FLAG)
取消窗口的最前：Call SetWindowPos(Me.hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, FLAG)
函数的第一个参数是根据实际情况改变的，它要求你给它传送一个窗口的句柄，这里的 Me.hwnd 就给函数传送了当前窗口的句柄，也就是将当前窗口前置或取消前置。如果要前置其他窗口，那么请向函数传送其他窗口的句柄，这个可以根据：FindWindow API函数获取。希望采纳意见，谢谢。。。
