由于任何程序最终都会在屏幕上显示其内容，因此可以对其进行捕获.即使您找到了检测正在运行的屏幕捕获软件的神奇方法.

Since any program ends up showing its content on a screen then it can be captured. Even if you found that magic way of detect running screen capture software.

我的意思是?信息通过VGA，HDMI或DVI电缆从CPU连接到显示器.如果用户不是将电缆连接到显示器，而是将其连接到外部视频捕获硬件，该怎么办?您可能不知道，所以我的建议是不要浪费您的时间.键盘上的Prt Scr键呢?

What I mean? Info runs through a VGA, HDMI or DVI cable from the CPU to the monitor. What if the user instead of plugging that cable to the monitor it does to an external video capturing hardware? You can't know it, so my suggestion is don't waste your time. What about the Prt Scr key on the keyboard ?

我相信甚至好莱坞都无法做到你想做的事.

I believe not even Hollywood can do what you want to do.
