I tried uploading the files to App_Data folder and then I added an image handler to display the image inside the webform.
I tested it and it worked perfectly fine in my localhost.
Now, after IIS installation, I can't seem to access the file and the image is not displayed.
What am I missing?
This is my code:
if (System.IO.File.Exists(Server.MapPath("~") + @"App_Data\" +pic.Replace("/", "\\")))
{
bimage.ImageUrl = "ShowImage.ashx?fileName=" + pic.Replace("/", "\\");
}
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Web;
namespace Qsoft_DMS
{
/// <summary>
/// Summary description for ShowImage
/// </summary>
public class ShowImage : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
System.Web.HttpRequest request = System.Web.HttpContext.Current.Request;
//HttpResponse r = context.Response;
string fileName = request.QueryString["fileName"];
string filepath = System.Web.HttpContext.Current.Server.MapPath("~") + @"App_Data\\" + fileName;
//int W = Int32.Parse(context.Request.QueryString["w"]);
//int H = Int32.Parse(context.Request.QueryString["h"]);
Image img = Image.FromFile(filepath);
Image _img = new Bitmap(img);
Graphics g = Graphics.FromImage(_img);
Point p = new Point(0);
g.DrawImage(img, p);
g.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighSpeed;
g.Dispose();
img.Dispose();
System.IO.MemoryStream str = new System.IO.MemoryStream();
// _img = _img.GetThumbnailImage(W, H, null, IntPtr.Zero);
_img.Save(str, System.Drawing.Imaging.ImageFormat.Png);
_img.Dispose();
str.WriteTo(context.Response.OutputStream);
str.Dispose();
str.Close();
context.Response.ContentType = getContentType(System.Web.HttpContext.Current.Server.MapPath("~") + @"\" + fileName.Replace("/", "\\"));;
context.Response.End();
}
public bool IsReusable
{
get
{
return false;
}
}
string getContentType(String path)
{
switch (System.IO.Path.GetExtension(path))
{
case ".bmp": return "Image/bmp";
case ".gif": return "Image/gif";
case ".jpg": return "Image/jpeg";
case ".png": return "Image/png";
default: break;
}
return "";
}
}
}
