有没有办法一次使多个窗口“活动”？在 Windows 中？

Question

假设我创建了一个程序，一个屏幕键盘。我想让它处于活动状态，以便它可以接收我的键盘输入，即使 Google Chrome 或 Notepad.exe 等其他程序也在接收我的键盘输入。我主要希望我的键盘像“Nohboard”一样运行我遇到了麻烦，因为一旦我的键盘看起来和像我想要的那样工作，每当我打开另一个窗口时，只要“Windows 7”专注于我的键盘就不会工作例如“notepad.exe”。我这样做的原因是使用我自己的软件在屏幕上监控我的击键。我正在尝试使用 gm studio 1.4 设计我的键盘，但无法同时激活多个窗口，每次我点击远离我可以创建的键盘程序时，我的键盘都会变得无用。 有什么可以使用的解决方法吗？也许由另一个程序创建的第 3 方脚本允许我的程序窗口“活动”并接收键盘击键输入，而另一个程序也处于活动状态并接收键盘击键输入？ 提前感谢任何能想到一个有用的解决方案的人。

我刚刚弄清楚如何使用自动热键脚本的一件事是将密钥发送到多个程序。有没有办法使用自动热键将其发送到“最后一个活动窗口”和“当前活动窗口”？

Answer 1

在 Windows 系统上，无法同时激活多个 Windows。

只能激活一个窗口。 （重点）

但是有两种方法可以帮助您解决问题。

1 - 例如，您可以在屏幕键盘窗口中忽略/禁用该键盘窗口的焦点。 （无焦点）（无激活 + +E0x08000000）

试试这个 Ahk 脚本。

注意：这是从 F1 到 F12 的屏幕按键条

Example1.ahk

Gui, +LastFound +AlwaysOnTop +ToolWindow -Caption +Border +E0x08000000
Gui, Font, s07, Arial
Loop, 12
Gui, Add, Button, % "x" 5+(A_Index-1)*60 " y5 w60 h25 vF" A_Index " gButton", F%A_Index%
Gui, Show, y0 w730 h35 NoActivate
Return

Button:
    SendInput, % "{" A_GuiControl "}"
Return

GuiClose:
    ExitApp
Return

~esc::exitapp

2 - 或者您可以使用第 3 方脚本，

注意：一起运行这两个脚本。 (KeypressValueToREG + ShowKeypressValue)

第一个是大型脚本，但您可以做很多事情，它会将您所有的鼠标和键盘移动放入只有一个 Windows 注册表项。

这个 KeypressValueToREG 脚本的强大之处在于，您可以在后台运行它，然后您可以在其他应用程序或其他语言 Visual Studio/Visual Basic/c++/Python/Autohotkey/?他们只需要访问/读取该一个注册表项。

KeypressValueToREG.ahk

;KeypressValueToREG.ahk comes from KeypressOSD.ahk that was Created by Author RaptorX
; Open this Script in Wordpad and For Changelog look to the Bottom of the script. 
;This code works with a getkeyname from a Dllcall (See Bottom Script- by Lexikos)
;you can press the esc key to exit.

如果您使用 Example1.ahk 中的技巧，那么您可以制作一个专业屏幕键盘，而无需关注窗口。

;run KeypressValueToREG.ahk - together with ShowKeypressValue.ahk
;The Features Are:
; - It will Show On your Screen, [All your Mouse Movements] and [All Keyboard Shortcuts Movement]
; - You can Make Scripts, that can do actions with MultiClicks on All Keyboard Shortcuts Clicks, How Cool Is that.
