从另一个应用程序中的控件获取文本(Internet Explorer) [英] Get text from a control in another application (internet explorer)

问题描述

我已经阅读了很多有关gettext和getwindowtext的文章.我可以获取Windows名称，但如何访问另一个应用程序中的控件并从文本框中提取文本?

I have been reading a lot about gettext and getwindowtext. I can get the windows name but how can I access a control in another application and extract text from a textbox?

推荐答案

使用 ^ ])，而不是.Net类名称-它不是Internet Explorer的顶级窗口.

如果WM_GETTEXT可与ie控件一起使用，但我会感到惊讶，但它会模拟
ctrl + a
ctrl + c
使用 SendKeys类 [

Use Spy ++[^] to figure out how to get the handle of the ie control - for IE 9 it will have a class named "Internet Explorer_Server" - that''s the window class (as registered with RegisterClassEx[^]), not the .Net class name - and it''s not the top level window for internet explorer.

I''d be surprised if WM_GETTEXT works with the ie control, but simulating
ctrl+a
ctrl+c
using the SendKeys class[^] will put the contents of the control on the clipboard.

来自MSDN :


要在另一个进程中检索控件的文本，请直接发送WM_GETTEXT消息，而不是调用GetWindowText.

From MSDN:


To retrieve the text of a control in another process, send a WM_GETTEXT message directly instead of calling GetWindowText.
