Title Body

The following method is taken from a WinForms app. It simply captures the screen, but I needed to modify it to work in a WPF application. When I use it, it returns a black image. The dimensions are correct. I have not got any open DirectX or videos and it wouldn't work even on my desktop. public static Bitmap CaptureScreen() { // Set up a bitmap of the correct size Bitmap CapturedImage = new Bitmap((int)SystemParameters.VirtualScreenWidth, (int)SystemParameters.VirtualScreenHeight, System.Drawing.Imaging.PixelFormat.Format32bppArgb); // Create a graphics object from it System.Drawing.Size size = new System.Drawing.Size((int)SystemParameters.VirtualScreenWidth, (int)SystemParameters.VirtualScreenHeight); using (Graphics g = Graphics.FromImage(CapturedImage)) { // copy the entire screen to the bitmap g.CopyFromScreen((int)SystemParameters.VirtualScreenWidth, (int)SystemParameters.VirtualScreenHeight, 0, 0, size, CopyPixelOperation.SourceCopy); } return CapturedImage; } Can anyone show me the error in my ways?
