How to use Windows Encorder

First you have to download encoder software http://www.microsoft.com/en-us/download/details.aspx?id=17792
(it's run time free we are using only run time library  )
the install it

Add  references to the project(Encoder all library has update into your VS dll table)

Using web camera or IP camera capture the rock image and save it in DB and Filtering data that are taken from the excel sheets.I used Windows encoder and those library and  Muthu created API to do those algorithm. Not only that but I did viewing part of that filtering data using graphs and user can came to conclusion using those graphs.
Important : I learn those things using CodeProject web site(http://www.codeproject.com/kb/cs/)

                {

                    using (Graphics g = Graphics.FromImage(bitmap))

                    {

                        // Get the paramters to call g.CopyFromScreen and get the image

                        Rectangle rectanglePanelVideoPreview = vidPanel.Bounds;

                        Point sourcePoints = vidPanel.PointToScreen(new Point(vidPanel.ClientRectangle.X, vidPanel.ClientRectangle.Y));

                        g.CopyFromScreen(sourcePoints, Point.Empty, rectanglePanelVideoPreview.Size);

                    }

                    string strGrabFileName = String.Format("E:" + i + ".jpg", DateTime.Now);

  //                 statusStrip1.Text = strGrabFileName;

                    bitmap.Save(strGrabFileName, System.Drawing.Imaging.ImageFormat.Jpeg);

                    string img1 = "E:" + i + ".jpg";

         }

}

Thank you

 

Specially I use lots of references specially codeproject(http://www.codeproject.com/ )
