在WindowNT5.0中最小化窗口，即使拥有窗口的线程被挂起也会最小化。在从其他线程最小化窗口时才使用这个参数。  Windows Server 2003, Windows 2000, and Windows XP: Minimizes a window, even when the thread that owns the window is hung. Only use this flag when minimizing windows from a different thread.

最小化显示 Hides the window and activates another window.

最小化指定的窗口并且激活在Z序中的下一个顶层窗口。 Minimizes the specified window, and activates the next top-level window in the Z order.

在窗口原来的位置以原来的尺寸激活和显示窗口。  Activates the window, and displays it at the current size and position.

依据在STARTUPINFO结构中指定的SW_FLAG标志设定显示状态，STARTUPINFO结构是由启动应用程序的程序传递给CreateProcess函数的。   Sets the show state based on the SW_ value that is specified in the STARTUPINFO structure passed to the CreateProcess function by the program that starts the application.

激活窗口并将其最大化  Activates the window, and displays it as a maximized window.

激活窗口并将其最小化 Activates the window, and displays it as a minimized window.
