捕获隐藏桌面的屏幕截图 [英] Capture screenshot of hidden desktop

问题描述

我在Windows上使用虚拟桌面使用简单的应用程序，我用C ++自己编码，我想知道是否有办法捕获次要/隐藏桌面的屏幕截图？
我知道我可以做SwitchDesktop - >捕获截图 - > SwitchDesktop，但它不是听起来像很好的解决方案....

I am using virtual desktops on Windows using simple app that i coded myself in C++, i was wondering if there is way to capture screenshot of secondary/hidden desktop ? I know that i can do SwitchDesktop -> capture screenshot -> SwitchDesktop, but it doesnt sound like good solution....

也许我运行一些窗口在隐藏的桌面，得到它的hwnd和SOMEHOW使用它来捕获整个屏幕？

Maybe i run some window in the hidden desktop, to get its hwnd and SOMEHOW to use it to capture the entire screen ?

我已经运行Spy ++，但似乎没有找到不属于目前的窗口

I have run Spy++ but seems it not finding windows that dont belong to currently active desktop.

提前感谢。
