如何使用 JScript 或 VBScript 控制 Windows 系统音量? [英] How to control Windows system volume using JScript or VBScript?

问题描述

我想通过 JScript 或 VBScript 脚本控制我的 Windows 系统的音量.有什么想法吗?

I want to control the volume of my Windows system from a JScript or VBScript script. Any ideas?

另外，如果系统音量被静音，我可以取消静音吗?

Also, can I unmute the system volume if it is muted?

推荐答案

要使系统音量静音或取消静音，您可以使用 WshShell.SendKeys 方法:

To mute or unmute the system volume, you can simulate the Mute key press using the WshShell.SendKeys method:

var oShell = new ActiveXObject("WScript.Shell");
oShell.SendKeys(Chr(&HAD));

至于从脚本更改音量级别，有一个涉及一些 Windows 自动化的解决方案，例如启动系统音量小程序并在其中模拟相应的键盘快捷键，但我认为它不可靠.因此，我建议您使用一些能够更改音量级别的外部实用程序，并从您的脚本中调用它.例如，您可以使用免费的 NirCmd 工具:

As for changing the volume level from a script, there's a solution that involves some Windows automation, such as launching the System Volume applet and simulating the appropriate keyboard shortcuts in it, but I don't think it's reliable. Therefore I recommend that you use some external utility capable of changing the volume level, and call it from your script. For example, you could use the free NirCmd tool:

var oShell = new ActiveXObject("WScript.Shell");

// Increase the system volume by 20000 units (out of 65535)
oShell.Run("nircmd.exe changesysvolume 20000");

// Decrease the system volume by 5000 units
oShell.Run("nircmd.exe changesysvolume -5000");

NirCmd 还可以将系统音量静音或取消静音:

NirCmd can also mute or unmute the system volume:

var oShell = new ActiveXObject("WScript.Shell");
oShell.Run("nircmd.exe mutesysvolume 0");  // unmute
oShell.Run("nircmd.exe mutesysvolume 1");  // mute
oShell.Run("nircmd.exe mutesysvolume 2");  // switch between mute and unmute
