How can I display a messageboxby typing a single Windows command, e.g. in the Rundialog from the Start menu, or in the [cmd.exe] command interpreter?
如何通过键入单个 Windows 命令来显示消息框，例如在“开始”菜单的“运行”对话框中，或在 [cmd.exe] 命令解释器中？

One way is to use apparently undocumented functionality, namely that [mshta.exe], the runtime engine for Windows .hta HTML applications, accepts a general URL as command line argument, including a javascript:protocol URL:
一种方法是使用明显未公开的功能，即 [mshta.exe]，Windows .hta HTML 应用程序的运行时引擎，接受通用 URL 作为命令行参数，包括javascript:协议 URL：
mshta "javascript:var sh=new ActiveXObject( 'WScript.Shell' ); sh.Popup( 'Message!', 10, 'Title!', 64 );close()"
This command can be issued in e.g. [cmd.exe]], or e.g. in the Rundialog from the Start menu, perhaps combined with the schtaskscommand to create a tea-timer…
这个命令可以在例如 [cmd.exe]] 中发出，或者在开始菜单的运行对话框中发出，也许结合schtasks命令来创建一个茶计时器......
The above messagebox times out after 10 seconds, but specifying a 0 second timeout means “don’t time out”, producing a more ordinary persistent messagebox.
上述消息框在 10 秒后超时，但指定 0 秒超时意味着“不超时”，生成更普通的持久消息框。
For a simpler messagebox you can instead use the alertfunction provided by the MSHTA host.
对于更简单的消息框，您可以改用alertMSHTA 主机提供的功能。

Found that if you copy msg.exe from a Win7 Pro machine to a Win7 Home machine it works. Copy msg.exe to and from the C:\Windows\System32 folder.
发现如果您将 msg.exe 从 Win7 Pro 机器复制到 Win7 Home 机器，它可以工作。将 msg.exe 复制到 C:\Windows\System32 文件夹或从 C:\Windows\System32 文件夹复制。

What if you create a small VBScript with the message you want to display? I.e. create e file, named "Message.vbs" with the content:
如果您使用要显示的消息创建一个小的 VBScript 怎么办？即创建 e 文件，命名为“Message.vbs”，内容如下：
MsgBox "Some info here", 0, "Message Title"
MsgBox "Some info here", 0, "Message Title"
and call it like this:
并这样称呼它：
cscript.exe PATH\Message.vbs
cscript.exe PATH\Message.vbs
