   //In the whole application 
   DicomEngine.Startup(); 
   using (DicomDataSet ds = new DicomDataSet()) 
   { 
      //Load DICOM File 
      ds.Load(dicomFileName, DicomDataSetLoadFlags.None); 
 
      int bitsStored = 16; 
      bool add = false;//Add a new window or replace the existing one(s) 
      int windowIndex = 0; 
      DicomWindowAttributes windowAttributes = new DicomWindowAttributes(); 
      if (ds.GetWindowCount(0) > 0) 
      {
