Detecting Screenshot Event

[Olby]

Hi,

I would like to receive screen print event and do some processing before the actual screen print is taken.
Something like: -> #IDHOT_SNAPDESKTOP/#IDHOT_SNAPWINDOW -> modify interface for the screen print -> return #True -> Windows takes screen print.
All I could do was to register a global hot key but then whenever my application is opened I receive the event but nothing happens afterwards. Is there a way to detect the event before and after the screen shot is taken without substituting windows screen print function with my own?

Thanks,

If you can block the message from being passed to windows
why not take the screen shot yourself?

I can but it would be more elegant if Windows did it.

maybe you should be using a low level keyboard hook instead
so you can get the message do what you need and send it back on its way.
