在另一个应用程序中获取当前关注的控件的句柄 [英] Getting the handle of the currently focused control inside another application

问题描述

人们将如何检索当前具有焦点的控件的句柄?我正在使用WH_KEYBOARD_LL捕获所有按键，并且我应该能够确定用户在哪个文本框中键入内容.捕获事件的代码无法直接访问 其他应用程序中的控件.

How would one retrieve the handle of the control that currently has focus ? I am using WH_KEYBOARD_LL to capture all keypresses in, and I should be able to determine in which textbox the user is typing in. The code capturing the events has no direct access to the controls in the other application.

我知道存在win32函数GetFocus()来获取当前的窗口句柄，但是对于当前控件，我需要类似的东西.

I know the win32 function GetFocus() exists for getting the current window handle, but I need something similar for the current control.

任何想法都会受到赞赏.

Any ideas would be appreciated.

推荐答案

您可以将GUI线程ID传递给

You can pass the GUI thread ID to GetGUIThreadInfo() which will provide you with a GUITHREADINFO.hwndFocus.
