这个要用到API
得到窗体的句柄Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
如果是自己的的就直接用me.hwnd好像就是你那个窗体的句柄
再根据其句柄改变窗休的显示.可以设其在最前要代码加我QQ
我
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
如果是你自己的窗体的话
dim b as long
b= SetWindowPos(me.hwnd, -1, 0, 0, 0, 0, 3)
me.hwnd可以换成其他程序的窗体.你就用findwindow()找也可以枚举.

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

private sub form_load()
SetWindowPos(Me.hwnd, -1, 0, 0, 0, 0, 3)
end sub
