Rapid desktop screen capture on Windows -

-

I want to capture desktop screen image on Windows.

I know about CreateCompatibleDC and CreateCompatibleBitmap. .. works in C ++ but they are very slow I need a more intense method that captures a screen for real-time updates. In Linux I can use Xlib functions, for example. Are there any high speed or system-level screencaps for Windows?

Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that?
