Hi all,

Is it possible to grab a screen shot of an application window even when the
PC is locked?

It is possible when it's not locked but just get a black image when it is locked.

推荐答案

不，可能不是。



麻烦的是，为了截取屏幕截图，你需要处理器时间 - 如果你可以获得处理器时间，那么你的系统很可能不会被锁定开始！ ：笑：

No, probably not.

The trouble is that in order to take a screenshot, you need processor time - and if you could get processor time, then there is a good chance your system wouldn't be locked up to start with! :laugh:

您可以使用数码相机或智能手机相机。



理论上，您可以远程连接到锁定的机器并读取当前显示。但如果在锁定之前尚未建立连接，则可能无法连接。



您甚至可能会使用GoToMeeting之类的电话会议软件来实现此目的 - 如果一端冻结，您仍然可以从另一端快照最后传输的显示。但如前所述，您需要在锁定之前进行连接。

You could use a digicam or your smartphone camera.

Theoretically, you may be able to remote-connect to your locked machine and read the current display. But if the connection isn't already established before it locks down, chances are that you can not connect.

You might even use some teleconference software like GoToMeeting for that purpose - if one end freezes you can still snapshot the last transferred display from the other end. But as stated before, you need to connect before the lock.
