推荐答案

过去，您可以从仿真器(如VT100)上抓取文本.它们是基于文本的.

您可以从网络浏览器中抓取文本，因为它们是基于文本(HTML)的.

但是典型的Windows窗体是渲染的图形图像.您将不得不诉诸OCR.那是一大堆您不愿打开的蠕虫.

您也许可以使用旧的Windows Get Text消息.您需要获取主窗口句柄，然后迭代子窗口.

Windows消息为WM_GETTEXT.

In the old days, you could scrape text off of emulators (like the VT100). They were text based.

You can scrape text off of web browsers because they are text based (HTML).

But a typical windows form is a rendered graphical image. You would have to resort to OCR. That''s a pretty big can of worms you don''t to open.

You might be able to use the old Windows Get Text message. You would need to get the main window handle and then iterate the child windows.

The windows message is WM_GETTEXT.

I would google WM_GETTEXT and whatever language you are using.

使用Excel(Office)InterOp.
