截取不可见窗口的屏幕截图

Question

（在Windows 7上）是否可以对不可见窗口进行屏幕截图（即不带WM_VISIBLE标志的窗口）？该方法最好是高性能的，因此我每秒可以捕获数百张这些屏幕截图。

Answer 1

也许您会在这里找到一些有用的信息： 从XP中的隐藏或剪切窗口复制内容？

Answer 2

Well-written Windows programs check that a window is visible before they paint themselves.

You are telling these windows not to render themselves, and then expecting them to render themselves. That is simply not going to work.
