Question

我有一个PowerShell脚本需要很长时间才能运行，除非我检查，否则我经常不知道它什么时候完成。

是否有一个命令，我可以坚持我的powershell脚本的末尾，可以在脚本运行时通知我，有点像Communicator聊天窗口在菜单栏上变黄，当有人给我发消息通知我去检查？

您可以从user32.dll导入FlashWindowEx，如本文http://learn-powershell.net/2013/08/26/make-a-window-flash-in-taskbar-using-powershell-and-pinvoke/

所示

Add-Type -TypeDefinition @"
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

public class Window
{
    [StructLayout(LayoutKind.Sequential)]
    public struct FLASHWINFO
    {
        public UInt32 cbSize;
        public IntPtr hwnd;
        public UInt32 dwFlags;
        public UInt32 uCount;
        public UInt32 dwTimeout;
    }

    //Stop flashing. The system restores the window to its original state. 
    const UInt32 FLASHW_STOP = 0;
    //Flash the window caption. 
    const UInt32 FLASHW_CAPTION = 1;
    //Flash the taskbar button. 
    const UInt32 FLASHW_TRAY = 2;
    //Flash both the window caption and taskbar button.
    //This is equivalent to setting the FLASHW_CAPTION | FLASHW_TRAY flags. 
    const UInt32 FLASHW_ALL = 3;
    //Flash continuously, until the FLASHW_STOP flag is set. 
    const UInt32 FLASHW_TIMER = 4;
    //Flash continuously until the window comes to the foreground. 
    const UInt32 FLASHW_TIMERNOFG = 12; 

    [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool FlashWindowEx(ref FLASHWINFO pwfi);

    public static bool FlashWindow(IntPtr handle, UInt32 timeout, UInt32 count)
    {
        IntPtr hWnd = handle;
        FLASHWINFO fInfo = new FLASHWINFO();

        fInfo.cbSize = Convert.ToUInt32(Marshal.SizeOf(fInfo));
        fInfo.hwnd = hWnd;
        fInfo.dwFlags = FLASHW_ALL | FLASHW_TIMERNOFG;
        fInfo.uCount = count;
        fInfo.dwTimeout = timeout;

        return FlashWindowEx(ref fInfo);
    }
}

在Powershell中有闪存窗口的命令吗？
