How to find a child of a parent unmanaged win32 app
提问by Joan Venge
Basically I am looking for a win32 method to invoke in C# to set the focus to a children of an unmanaged application.
基本上，我正在寻找一种在 C# 中调用的 win32 方法，以将焦点设置为非托管应用程序的子级。
But first I need to find the child control's handle which is the problem. Any useful win32 functions to solve this?

SystemWindow.AllToplevelWindows
and then just dig your way down (looking at class names, process names, titles, dialog IDs, whatever).
然后继续往下挖掘（查看类名、进程名、标题、对话框 ID 等等）。

Have you tried to use FindWindowEx?
您是否尝试过使用 FindWindowEx？

Use FindWindowExto find the Handle of the Window you're looking for. Once you have that handle, use EnumChildWindowsto find the correct child you need. There's too much code involved for me to quickly write up a sample, but there's enough on the web to help.
使用FindWindowEx查找您要查找的窗口的句柄。获得该句柄后，请使用EnumChildWindows查找所需的正确子级。涉及的代码太多，我无法快速编写示例，但网络上有足够的帮助。
