C# - Hide An Image Path On Asp Page Without Http Handler?
Apr 20, 2010
I have many static images under a directory in my site structure, and I'm not concerned with hotlinking or copy-protecting the images. For a myriad of reasons, what I need to do is not show the image path on the site (or show a fake one).
Is there any way to do this without resorting to an http handler or a worker asp.net page?
i redirect a page from http to https using http module begin request handler .i am calling webservice using ajax but it is saying webserice not defined .which otherwise works fineits work fine when rediect page in page_load instead .but i need to add function for https to http in every page. i still not know why ajax is not working when i use http module for redirect
I have div In my page that in this div I put image control
<div id="DLogos"> <asp:Image ID="imglogo" runat="server" CssClass="ILogos" /> </div> according to below code <div id="Dart1_I1" visible='<%# !string.IsNullOrEmpty(Eval("image1").ToString())%>'>
If in database was image it show div and if there wasn't any image it didn't show div but above code is for div that I put in datalistnow I want do some thing like that for Div that I don't put it in datalist I should write code for that in behindecode page but I don't know How I can do it?behind code
SqlCommand _cmd = new SqlCommand("storeinfo1", _cn); _cmd.CommandType = CommandType.StoredProcedure; _cmd.Parameters.AddWithValue("@behcode", data); _cn.Open(); SqlDataReader _dr = _cmd.ExecuteReader(); while (_dr.Read())
In my MSSQL Server I have a table named Nomogram including an attribute named Img1 which include an image of type varbinary(MAX)I wish to load that image on my webform using an http-handler (ashx).How do I do that? I have looked at this sample but I can figure it out how to solve my exact problem. [URL]
I create custom HTTP handler for auto generating file and I want to tell IIS7 to serve current request like normal static file because I need to use IIS and web.config file to control compression setting and any other HTTP header of current requested file.I know. there is an internal class called StaticFileHandler in ASP.net. But I cannot access it. Or you have any other way to work like this.
I am trying to convert the virtual path to a physical path but don't seem to have Server.MapPath or HttpServerUtility.MapPath available in my handler. I add the System.Web namespace with no luck.
We are using the Facebook API and receive back URLs for profile image thumbnails. Unfortunately the protocol is restricted to just HTTP and it doesn't support HTTPS. The page on our site that hosts the thumbnails is always delivered via HTTPS, and if we use HTTP for the thumbnails the user will receive security warnings from their browser.
Solution:
Build an HTTP Handler that "passes through" the image from the Facebook URL, but allow the handler to be called via HTTPS. Before I started coding I thought I could something like this:
but I ended up having to save the image to an object in memory than write the image to the Response.OutputStream using the image save function.
Current Code:
[Code]....
This seems inefficient but I can't find a way of using the HTTP Handler as I orginally intended. Is there way of accomplishing the goal without creating the image memory and just "passing through" the call?
as it uses the relative path the http module is unable to understand the path and throwing following error
The file '/Root/Pages/Master/Site.Master' does not exist.
error occurred during the parsing of a resource required to service this request. review the following specific parse error details and modify your source file appropriately.
I'm trying to write an HTTP GET handler. The path should start with http://site/processTask and have a set of URL-encoded parameters. I have the following in my web.config
now when I type the URL http://mysite/processTask in browser I get HTTP 404 but if I change the add verb line to the following one:
<add verb="GET" path="processTask.asmx*" type="MyHandler.ProcessTaskHandler, MyHandler"/> and type http://mysite/ProcessTask.asmx in browser the handler is run and I get the response from the handler. What's the problem? Why is the handler run only when the path contains .asmx? How do I change web.config so that .asmx is not required?
I've created a class library project and this has a class implementing the IHttpHandler interface. Let's call this class ZipHandler. Let's say the namespace is Zip. I want that whenever any Http request comes for a zip file, my ZipHandler should handle it, regardless of whether the request is to an Asp.Net application or a normal virtual directory.
Queries:
Is it possible (it should be given the hype about integrated pipeline etc. in IIS 7)? How to do it?
I am new to this topic. SO please look over my stupid mistakes. I have web application and its virtual directory path is as followshtpp://localhost/TxtXmlImggHandler/This root has three pages one for text, one for xml, one for images. Actually these pages call three different handlers. I had no problem when I send/receive some data to HTTPHandler for processing, had no problem when I request xml file from HTTPHandler.Now I am trying to get image from HTTPHandler, but no luck. All my HTTPHandlers are sitting in root of my web application
I successfully added and configured HttpHandler in an Asp.Net WebApplication, but facing problems while trying to add same HttpHandler to Asp.Net WebSite. I have registered it in the web.config, am i missing something This is the error I am getting Configuration Error
Description:
An error occurred during the processing of a configuration file required to service this request. Parser Error Message: Could not load type 'MyHandler'.
Line 98: </pages> Line 99: <httpHandlers> Line 100: <add verb="*" path="*.result" type="MyHandler"/> Line 101: <remove verb="*" path="*.asmx"/>
Here is handler
public class MyHandler: IHttpHandler { #region IHttpHandler Members public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { } #endregion }
NOTE: I have not made any request for the handler via url, it is just not letting me run application.
Scenario: I have a bunch of web applications for which I want to add a simple ping functionality via http handler. Example: [URL]
Problem: For some of the applications this approach does not work becasue of custom HttpModule. These modules have some depedency on either authentication or some other processing logic due to which it makes the request invalid.
I am trying to find a solution to get this ping functionality work without making any changes to existing HttpModules.
UPD: Seems like the cause of problem is that HTTP handler response isn't caching on server. The following code works well for web-form, but not for handler:
I want to use HTTP Handler in order to create a RSS feeds. For the purpose, I want to put my logic for creating the rss XML in C# class, which implement IHttpHandler, then to "map" this handler into the web.config file and to register the "mapped name" in my routing rules. I am doing something like this:
public class RSSFeedHandler:IHttpHandler { public void ProcessRequest( HttpContext context ) { [code]...
I have the next problem: I need to process only 1 request at a time from each user. Lets assume that server identifies each user be UserID, sent in query string.cHow can make the server work the way like FIFO (do not start processing next request until the previous is fully processed)? Should I use the named mutexes inside HTTP handler and assign the name to mutex by UserID?
