I have implemented a generic handler to work as a restful web service in ASP.Net. I have a problem receiving the XML file that is being posted to this web service. I cannot actually see anything being passed. I have gone through the form, querystring, and file properties of the request object. Everything is empty. I know that the file has been posted correctly because I can see it while using a port sniffer.
How can I access this file?
Here is the situation,
- a user submits a form from cfm page, then cfm page transfers data to asp.net(C#) page
here is cfm form tag
<form name="form1" action=[URL]
method="post" target="_blank">
<input name="fName" value="Hello" type="text" />
<input name="LName" value="World" type="text" />
</form>
How can I write asp.net c# to get inputs from cfm page?

View 4 Repliesi have a ashx file

i want ro read this from another page
Like:

i have another page: http://www.domain2.com/default.aspx ( I want write string(Return From ashx file))
I have a simple 'file download' generic handler which sets the response contenttype and headers before sending the file through the same response.
I also have Response.Cache.SetCacheability(HttpCacheability.server) set in the global.asax.
As I have noticed from various sources, Internet Explorer doesn't like this no-cache setting and gives an error when trying to download the file (requested site unavailable or cannot be found).
I thought maybe I could override this setting in the .ashx page, so I alter the response's cacheability setting to public. This did not solve the issue. removing the line from global.asax does solve the problem but obviously affects the whole site.
Is there a way of setting the cachability just for my generic handler?
There is an ashx file containing "ProcessRequest(HttpContext context)" method which gets triggered automatically. When and how does it get fired?Another question, How can I get the current QueryString when I am inside this file? When I type "context.Request.QueryString" it says it's null or empty although the address have arguments.
View 1 RepliesIf I access session variable in ashx handler through it is always null. How can I access the current user here.
public void ProcessRequest (HttpContext context) {
context.Session[UIConstants.SessionItems.ID] = Id;
}
THere is an external ASHX url that dinamically generates an XML file.
I tried to parse this XML using the doc.Load("http://www.domain.com.br/asp.net/integration.ashx") but it haven't worked.
The same code above work fine if I use a XML file instead of ashx one.
I need to read the XML file generated by the ASHX one in order to integrate the websites.
In a basic scenario where I have a GridView with files to download and link buttons to download them, is there any benefit at all for creating a custom http handler for streaming those files as opposed to simply streaming from the event handler of the download link button?
Edit: As some suggested code reuse would favor the handler, however it's not an issue in this particular case. The handler is also faster being that it avoids the page life cycle, however this slight performance improvement is probably not worth creating a handler for in my particular situation. The only thing that comes to mind now is (assuming using the same aspx page approach) whether there is any special consideration in a situation where the GridView is inside an UpdatePanel?
I have created file upload funactionality along with progress bar in my project for this. I have referred following jquery tool you can see here.[URL]with the respective funcationality. i have created one .ashx file for string file on server but when i try to store file on server it gives me error.Could not find a part of the path so i put whole path in the respective code but still i m getting some error. my code is
sfilenamestored = ("\Users\dev5\Desktop\DataAccessLayer\PresentationLayer\"+"/Uploaded_Document/" + upload_files.foldername.ToString()) + "/" + GetUniqueKey() + file.FileName;
For our application we provide users with file downloads that utilize handlers to serve the files. Currently, the way it is served to the user is through window.location. When using this, at times, it causes issues under IE8. When an error occurs, it cannot be caught under the page that called it.
A) Is there a way to serve an ashx file handler to the user where the page that called it can catch any exceptions made from thje handler
B) What is the correct way to serve the handler, eg. window.open, window.location, etc. Would return false at the end of the javascript solve this? Are there any other ways
implemented a generic handler in my application which works great for images, but when I manually type the handler URL in the browser with the image's querystring it prompts download instead of displaying. Here is my code:
public void ProcessRequest(HttpContext context)
{
if (this.FileName != null)
{
[code]...
I have the below code which does not work. I cannot instantiate my class this way.
SecurePage secureCs = new SecurePage();
I want to be able to inherit the class instead of instantiating.

View 5 RepliesWe have a whole bunch of WML pages that are served out using ASHX files and we've had no problems with them. However, someone has just got a Windows 7 Phone and when they browse to one of these pages they get:

I'm using an .ashx handler to retrieve an image file... It queries a local database, which retrieves the URL of an image which is hosted on Amazon S3.
But I can't use context.response.write(AmazonS3URL) because it returns the error '...is not a virtual path'.
Can context.response.write only return files that are on the local machine? Or is there another function to call remote files?

I have read in many places that referencing IRequiresSessionState or IReadOnlySessionState will allow me access to the Session scoped variables from within the ProcessRequest method in an ASHX file.
I have implemented these changes, as follows, and I am unable to retrieve this data still, as the server returns a null object reference error:
using System;
using System.Web;
using System.Web.SessionState;[code]....
The error is most certainly specific to pulling data from the session, yet I am 100% certain that the session contains data in this key.
It shouldnt matter where I am storing the data (cookies, vs db, etc), right?

View 10 RepliesI'm working on a project that has a C# app (running 24/7 as a server) on the client's machine). This app needs to send a file as a byte stream via POST to a server I am currently hosting on my home desktop.
Can this file be received by a C# app running on my server, or does it have to be as ASP app/page?
Also, I know how to send a bytestream via POST, but how will I set my server side app to listen for this incoming data? I have never done something like this, so I'm looking for some pointers to get me started.
