将窗口内容打印到文件 [英] print window content to a file

问题描述

我想运行一个程序来识别所有当前打开的窗口，然后将它们的内容打印成单独的png（每个窗口分成一个png）。

这有可能吗？

我真的可以使用一些帮助......我是新手。

提前致谢

解决方案

我不确定它是怎么回事在W10中完成，但在W7中，您需要显示要打印的窗口。即，仅当窗口在屏幕（例如LCD监视器）上完全可见时，窗口的内容才被激活。但是，您可以更改设备上下文并将
重定向到重新绘制窗口的内存设备上下文。

Hi,

I would like to run a program which identifies all currently opened windows and then prints their contents into seperate pngs (each window into one png).

Is this possible at all?

I could really use some help.. I'm a newbie to this.

Thanks in advance

Hi,

I am not sure how it is done in W10, but in W7 you need to display a window you want to print. i.e. the content of the window is protted only if the window is fully visible on a screen (e.g. LCD monitor). However, you can change the device context and redirect the drawing to memory device context at the window is re-drawn.
