Clipboard.SetDataObject seems not to work in Adobe Acrobat Protected Mode

 public void CopyToClipboard()
 {
     try
     {
         Size s = tape.GetPrintSize(0);
         if ((s.Width > 0) && (s.Height > 0))
         {
             const int margin = 20;
             s.Width += margin + margin;
             s.Height += margin + margin;
             Bitmap bmp = new Bitmap(s.Width, s.Height);
             Graphics gcs = Graphics.FromImage(bmp);
             gcs.FillRectangle(Brushes.White, 0, 0, s.Width, s.Height);
             gcs.DrawRectangle(Pens.Black, 0, 0, s.Width - 1, s.Height - 1);
             tape.Print(gcs, new Point(margin, margin), 0);
             Clipboard.SetDataObject(bmp);
         }
     }
     catch (Exception)
     {
         DisplayError("Error saving image to clipboard");
     }
 }

 Issue while i am trying to copy a bmp object to clipboard from a windows form ,my code works perfectly fine in non-protected mode ,but fails in protected mode.
