Exception was unhandled

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!!!
