Web Forms :: Fetching Of Files Saved In Database Using Generic Handler Is Slow
Jul 8, 2013
I have used [URL]....
above method to save and retreve files from sql server database. I have uploaded around 50-60 images as jpg. But it taking so much time to get display online. but it's working faster when accessing from local database.
There's the page where images are displaying [URL]....
Is the speed for images retreiving from sql database is slower as compared to retrieving images from folder..?
.vb code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
scroll = fillbannerpics()
End If
End Sub
[CODE]..

I need displaying my image file stored from my database into the image control. I've had read some articles and watch video tutorial which there were perfectly working and I followed it but I wasn't able to make it work. The image control just displayed blank. I used Generic Handler to retrieve the image file from my database based on the articles and tutorials I've got. here are my codes below:
Generic Handler:
Code:
<%@ WebHandler Language="C#" Class="ShowImage" %>
using System;
using System.Configuration;
using System.Drawing;
using System.Drawing.Imaging;
[Code] ....
Asp.Net Code for the Image control:
HTML Code:
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "ShowImage.ashx?ID=" + Eval("ID") %>' Height="128px" />

I have write a simple generic handler with VB as the language.
I am then trying to access the static properties of the handler via an aspx page using <%= handlerclassname.propname %> code.
However it is failing to compile. The compiler throws an error Name HandlerClassname is not declared.
I have checked in my code about namespace or something like that, but there aren't any.
Compilation option in web.config is
<compilation
debug="true"
strict="true"
explicit="true">

In Visual Studio 2010, when you say new Item, you can see Asp.NET Handler and Generic Handler. Can you tell me what's the difference, I think it came with .NET 4.0 because I couldn't find related thins on Google.

I Have a generic handler that's serving member logo images:
http://site.com/logo.ashx?memberid=123
Now, I want to use it by caling a url like:
http://site.com/logo/john.jpg
So I would create a route for that (pattern: "logo/{username}.jpg"). But, my problem is - how do I retrieve {username} when inside ProcessRequest() of my generic handler? It's not a page, so I can't get Page.RouteData.Values.

I am new to MongoDB and have a perfect place in mind to use it. However, it's only worth it if I can make the queries from JavaScript and return JSON.
What's the easiest way I can implement a generic service/handler in asp.net/c# that would allow me to interact with mongodb via JavaScript? I understand JavaScript can't call mongodb directly, so the next best thing is what I'm looking for.

I am creating a myspace application and for some database entries I am using generic handlers which I have hosted on another website. From my myspace application I use ajax calls to those handlers to perform the activities that I want. I want to know how can I make these ajax calls secure? I mean I want to be sure that the handlers are being called by only the myspace app and not by entering url into the browser etc.

How can i resolve a virtual path to a file into a path, suitable for the browser, from within a generic .ashx handler?
e.g. i want to convert:
~/asp/ClockState.aspx
into
/NextAllowed/asp/ClockState.aspx
If i were a WebForm Page, i could call ResolveUrl:
Page.ResolveUrl("~/asp/ClockState.aspx")
which resolves to:
/NextAllowed/asp/ClockState.aspx
But i'm not a WebForm Page, i'm a generic handler. You know, that IHttpHandler object with all kinds of things injected:

I have a WYSIWYG editor on one of my forms and I want to send the contents of the editor to an ASP.NET generic handler for processing via an Ajax call.
I am having a little bit of trouble parsing the html received.
Client Side:
$(function(){
$('.send').bind('click', function(event){
var message = $('#TxtMessage').htmlarea('toHtmlString');
message = escape(message);
[Code]....
So the problem is that even when I call Server.HtmlDecode(string) the message is garbled.

I'm busy writing a handler to serve various documents for download or presentation in web forms pages. The documents range from various image formats, to PDF, to MS Office documents, to generic binaries. My basic draft of the download process is as below:
[code]....
However, I have some misgivings about lumping all documents together as application/octet-stream, and I would prefer, if feasible, to use a more specific content type per document type. I have a DB table for document types where I could store this. Am I going in the right direction, and if so, where can I find a suitable starting list of content types for document types?

I have a Silverlight application hosted in an ASP.NET site, through which I'm starting an HttpWebRequest to a Generic Handler in order to save a CSV file to the user's machine.
From the Silverlight app, a Uri is constructed with parameters to make the CSV file server-side. A button is clicked which triggers the following:
string httpHandlerName = "HttpDownloadHandler.ashx";
// CustomUri handles making it an absolute Uri wherever we move the handler.
string uploadUrl = new CustomUri(httpHandlerName).ToString();
UriBuilder httpHandlerUrlBuilder = new UriBuilder(uploadUrl);
httpHandlerUrlBuilder.Query = string.Format("{3}startdate={0}&enddate={1}&partnerId={2}", startDate, endDate, partnerId, string.IsNullOrEmpty(httpHandlerUrlBuilder.Query) ? "" : httpHandlerUrlBuilder.Query.Remove(0, 1) + "&");
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(httpHandlerUrlBuilder.Uri);
webRequest.Method = "POST";
webRequest.BeginGetResponse(new AsyncCallback(GetResponseCallback), webRequest);
Now here is the ProcessRequest code from the HttpDownloadHandler.ashx
public void ProcessRequest(HttpContext context)
{
_httpContext = context;
string partnerId = _httpContext.Request.QueryString["partnerId"];
string startDate = _httpContext.Request.QueryString["startDate"];
string endDate = _httpContext.Request.QueryString["endDate"];
ExportCsvReport exportCsv = new ExportCsvReport();
_csvReport = exportCsv.ExportMemberRegistrationReport(partnerId, startDate, endDate);
context.Response.Clear();
context.Response.AddHeader("content-disposition", "attachment; filename=Report.csv");
context.Response.ContentType = "text/csv";
context.Response.Write(_csvReport);
}
Here is the HttpResponse header information that comes back when the Save File Dialogue refuses to appear:
{System.Web.HttpResponse}
Buffer: true
BufferOutput: true
Cache: {System.Web.HttpCachePolicy}
CacheControl: "private"
Charset: "utf-8"
ContentEncoding: {System.Text.UTF8Encoding}
ContentType: "text/csv"
Cookies: {System.Web.HttpCookieCollection}
Expires: 0
ExpiresAbsolute: {1/1/0001 12:00:00 AM}
Filter: {System.Web.HttpResponseStreamFilterSink}
HeaderEncoding: {System.Text.UTF8Encoding}
Headers: 'context.Response.Headers' threw an exception of type 'System.PlatformNotSupportedException'
IsClientConnected: true
IsRequestBeingRedirected: false
Output: {System.Web.HttpWriter}
OutputStream: {System.Web.HttpResponseStream}
RedirectLocation: null
Status: "200 OK"
StatusCode: 200
StatusDescription: "OK"
SubStatusCode: 'context.Response.SubStatusCode' threw an exception of type 'System.PlatformNotSupportedException'
SuppressContent: false
TrySkipIisCustomErrors: false
When I navigate to localhost/HttpDownloadHandler.ashx while the site is up, without initiating it from within the Silverlight app - the Save File Dialogue appears just fine, it seems to be a case where Silverlight is not accepting the response header properly.

I've created a Web application (VS2008) that contains a single Generic Handler (handlername.ashx) and a web.config. I've also added a Web Setup project to use for deployment that uses the primary output from the Handler project. Install works without any errors and all the referenced DLLs are installed in the target location, with one issue. It doesn't install the ASHX file or the web.config.
Publishing the web app to the target location works as expected (includes both DLLs and the ASHX/Config files).
Is there something specific I need to do for the Web setup to include the ASHX/Config files?
