设置自动隐藏 Windows 任务栏的命令或消息或 DLL 调用? [英] A command or message or DLL call to set automatic hiding of Windows taskbar?

问题描述

我需要以编程方式设置或切换自动隐藏 Windows 10 任务栏.绑定到热键的操作以提高生产力和便利性.是否有命令行命令或 DLL 调用可以实现相当于翻转以下开关:

I need to set or toggle auto-hiding of Windows 10 taskbar programmatically. An action bound to a hotkey for productivity and convenience. Is there a command-line command or a DLL call which allows to achieve equivalent of flipping the following switch:

目前我通过打开上面的设置窗口并发送按键进行搜索来实现这一点，然后是Downs和Space和Alt+F4 但速度慢且不可靠.

Currently I am achieving this by opening the above Settings window and sending keystrokes for search, followed by Downs and Space and Alt+F4 but it is slow and unreliable.

这个问题不是特定于语言的，因为 DLL 调用在任何地方看起来都差不多，尽管我的最终实现将在 AutoHotKey.

This question is not language-specific since DLL calls look pretty much the same everywhere, although my final implementation will be in AutoHotKey.

预期结果:运行该命令后，Windows 资源管理器将更改其行为，就像启用(或禁用或切换)设置在桌面模式下自动隐藏任务栏一样.

Expected result: After running the command, the Windows Explorer will change its behavior as if the setting Automatically hide the taskbar in desktop mode was enabled (or disabled or toggled).

推荐答案

ABM_SETSTATE 消息.

在找到合适的 Windows 消息后我在 实施://www.autohotkey.com/" rel="nofollow noreferrer">AutoHotKey:

It is ABM_SETSTATE message.

After finding the proper Windows message I have also found the implementation in AutoHotKey:

ABM_SETSTATE    := 10
ABS_NORMAL      := 0x0
ABS_AUTOHIDE    := 0x1
ABS_ALWAYSONTOP := 0x2
VarSetCapacity(APPBARDATA, 36, 0)
Address := NumPut(36, APPBARDATA)
Address := NumPut(WinExist("ahk_class Shell_TrayWnd"), Address + 0)
NumPut(ABS_NORMAL, Address + 24)
DllCall("Shell32.dll\SHAppBarMessage", UInt, ABM_SETSTATE, UInt, &APPBARDATA)

将第二行中的参数从ABS_NORMAL改为ABS_AUTOHIDE，以达到预期的其他状态.

Change the parameter in the second line from the bottom from ABS_NORMAL to ABS_AUTOHIDE to achieve the expected other state.
