获取外部程序句柄

Question

I made a small program in C++ that can type text into a notepad document, it does so using FindWindow and FindWindowEx, but I was only able to do that because I knew the names of the windows I was trying to access (in this case it was "Notepad" for the doc and "Edit" for the text area).

If I didn't know the names how would I go about figuring that out? Lets hypothetically say I wanted to make text appear in Chrome's URL box, how would I figure out what the name of that box is so I can use FindWindowEx on it?

Answer 1

The least painful approach to automating 3rd party applications is to use UI Automation . It allows you to navigate UI hierarchies as well as operate on the individual objects.

All native windows controls support UI Automation out of the box. UI Automation also works with frameworks, that do not implement their UI using native controls (eg Qt). Particularly with Qt, tools like Spy++ will not give you the information you need.

运行另一个应用程序，然后使用Spy ++，Winspector等工具查看另一个程序的窗口层次结构，以查找所需的内容。
