yes i save graphics from g, where g is printscreen from rectangle where i put picture box. So if i put picturebox top left with height 50 and width 50, it will save it top left screen(it take picture from picturebox). If i put middle of screen so it will take it too. But with lambda expresion, it take picture from somewhere i dont know because it is only grey area...

Ok I changed it a little bit, however same idea. So that you know what image you're getting, I have the image saved to your desktop

Code: Select all

        Invoke(
            DirectCast(
                Sub()
                    Using bmp = New Bitmap(CameraView.Width, CameraView.Height)
                        Using g = Graphics.FromImage(bmp)
                            Dim sourcePoints = CameraView.PointToScreen(New Point(CameraView.ClientRectangle.X,
                                                                                  CameraView.ClientRectangle.Y))
                            g.CopyFromScreen(sourcePoints, Point.Empty, CameraView.Size, CopyPixelOperation.SourceCopy)
                            bmp.Save(My.Computer.FileSystem.SpecialDirectories.Desktop + "\pic.bmp", ImageFormat.Bmp)
                  End Using
                  End Using
                  End Sub,
                MethodInvoker))
