调用win32 API 实现窗口的最小最大化，特别应用在IE窗口操作上，可以有效的释放占用内存。

Public Function min_and_max(hwnd)

        Extern.Declare micVoid ,"SendMessageA","user32.dll","SendMessageA",micHwnd,micInteger,micInteger,micInteger
        SC_MINIMIZE =61472
        SC_MAXIMIZE =61488
        WM_SYSCOMMAND = 274
        Extern.SendMessageA hwnd,WM_SYSCOMMAND,SC_MINIMIZE,0
        wait 1
        Extern.SendMessageA hwnd,WM_SYSCOMMAND,SC_MAXIMIZE,0
End Function
