Exception was unhandled

Exception was unhandled

• mkamioner

  The real code is very big, but I can put a part of it. The line at which the exception occurs is underlined.

  private void displaymap()

  {

  if (bmp_map != null)

  {

  picturebox_map.Image = null;

  bmp_map.Dispose();

  }

  if (bmp_map_zoom != null)

  {

  picturebox_map.Image = null;

  bmp_map_zoom.Dispose();

  }

  if (g != null)

  {

  g.Dispose();

  }

  bmp_map = new Bitmap(@"\Localize\Images\" + currentfloor.TrimStart('f', 'l', 'o', 'r', '-') + ".jpg"); <<<<<<<<<<<<<<<< this is where exception occurs.

  bmp_map_zoom = new Bitmap((int)(Math.Round((double)(bmp_map.Width * 0.25 * zoom_index), 0)), (int)(Math.Round((double)(bmp_map.Height * 0.25 * zoom_index), 0)));

  g = Graphics.FromImage(bmp_map_zoom);

  g.DrawImage(bmp_map, new Rectangle(0, 0, bmp_map_zoom.Width, bmp_map_zoom.Height), new Rectangle(0, 0, bmp_map.Width, bmp_map.Height), GraphicsUnit.Pixel);

  picturebox_map.Width = bmp_map_zoom.Width;

  picturebox_map.Height = bmp_map_zoom.Height;

  picturebox_map.Image = bmp_map_zoom;

  picturebox_map.Visible = true;

  int ax = (int)(Math.Round((double)(Int32.Parse(tnx[0].ToString()) * 0.25 * zoom_index), 0));

  int ay = (int)(Math.Round((double)(Int32.Parse(tny[0].ToString()) * 0.25 * zoom_index), 0));

  int bx = (int)(Math.Round((double)(Int32.Parse(tnx[1].ToString()) * 0.25 * zoom_index), 0));

  int by = (int)(Math.Round((double)(Int32.Parse(tny[1].ToString()) * 0.25 * zoom_index), 0));

  int cx = (int)(Math.Round((double)(Int32.Parse(tnx[2].ToString()) * 0.25 * zoom_index), 0));

  int cy = (int)(Math.Round((double)(Int32.Parse(tny[2].ToString()) * 0.25 * zoom_index), 0));

  x_topnode = ax;

  y_topnode = ay;

  x_topnode_centre = -x_topnode + 120;

  y_topnode_centre = -y_topnode + 146;

  picturebox_map.Location = new Point(x_topnode_centre, y_topnode_centre);

  picturebox_map.Refresh();

  Point previous_one = new Point(ax, ay);

  Point previous_two = new Point(bx, by);

  Point previous_three = new Point(cx, cy);

  Point[] localization_triangle = { previous_one, previous_two, previous_three };

  g.DrawPolygon(new Pen(Color.OrangeRed), localization_triangle);

  g.FillEllipse(new SolidBrush(Color.Red), ax - zoom_index, ay - zoom_index, zoom_index * 2, zoom_index * 2);

  g.FillEllipse(new SolidBrush(Color.Orange), bx - zoom_index, by - zoom_index, zoom_index * 2, zoom_index * 2);

  g.FillEllipse(new SolidBrush(Color.Yellow), cx - zoom_index, cy - zoom_index, zoom_index * 2, zoom_index * 2);

  picturebox_map.Refresh();

  progressBar1.Value = 0;

  progressBar2.Value = 0;

  progressBar3.Value = 0;

  zoomin.Enabled = true;

  zoomout.Enabled = true;

  }

  I wonder if its going to be of any use to assist me. I'll wait for any suggestions.

  Thanks!!!

  Looking at the exception stack trace I would guess that there was some error while reading data from the image file. An easy thing to check would be making sure that the file you are loading also loads properly in some other image viewing program. Also do you know if your device supports loading JPG images (NetCF relies upon OS support for imaging operations so not all image types work on all devices)

  Where is the exception being thrown from can you show us the code where the exception is being thrown from
