How can you prevent a window being captured by Print-Screen?
- by John
I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios.
Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard?
I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.
