  1. My whole "Project" is to take two screenshots(main and secondary display) and then read a few pixels to get the color of these. After I got the pixels, I want to calculate a bit with them.  Since I want to take this screenshots continuously, I have to use directX for better performance.   I tried some other methods to take a screenshot, but they are to slow.    The directX solution is in another clean project to test it before I implement it in my "main" project.     Just want to know if it is possible to take a screenshot from my second monitor.
  2. That's the whole project. Just want to take a screenshot from my main and secondary display with directx.   After changing to d.GetFrontBufferData(1, s);  i got this error:     D3DERR_INVALIDCALL: Invalid call (-2005530516)
  3. Thats what I have so far: http://paste.ofcode.org/EfjDzzQ5tJsVZ2mQe7Tnfq   With: Bitmap bitmap = sc.CaptureScreen()  I can easily take a screenshot from my main desktop.     I'm still a beginner in programming.
  4. I can take a screenshot. Its working fine for me. I just dont know how i can take a screenshot from my second desktop.      I tried "Screen.AllScreens" without success.
  5.  Thanks, but this didnt help...
  6. Hi,    How can I take a screenshot on my secondary screen? Thats what i have. public Bitmap CaptureScreen() { using(Surface s = Surface.CreateOffscreenPlain(d, Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, Format.A8R8G8B8, Pool.SystemMemory)) { d.GetFrontBufferData(0, s); Bitmap b = new Bitmap(SlimDX.Direct3D9.Surface.ToStream(s, SlimDX.Direct3D9.ImageFileFormat.Bmp, new Rectangle(222, 222, 500, 500))); s.Dispose(); return b; } } This works great, but only for my main display. I could not find anything useful with Google. Please help me.   Thanks and Greetings
