How to detect the snapshot button? RRS feed

  • 질문

  • I'm developing an application to capture using a USB Camera. I need to detect when the USB Camera snapshot button is pressed.  I haven't been able to find a way to detect when the button is pressed. Is there a directshow event?, or a USB event I can detect when the button is pressed? Or is there some other way of detecting the button?
