In my new job, they have already written an httphandler to handle all the .aspx files, and they are not using asp.net's httphandler. Now, I want to use asp.net's regular .aspx httphandler for some web pages (.aspx files) in the project and the other pages need to be handled using their customized httphandler, i.e., 2 httphandlers for same file type (.aspx), how to do this?

View 1 RepliesI am having a specific requirement of which I am not sure it is even possible to do but I have read somewhere in the past few days that similar to what I am trying to achieve shoud be done by writing a custom HttpHandler (or module?). Basically, I currently have a simple aspx page that accepts a file upload and forwards it to another URL (after doing some checking). The way this currently works is that my Page_Loaded gets called only after the entire file is uploaded.
What I am looking to achieve is get a hold of an uploaded file Stream early on as soon as request headers are processed so I could do some sort of piping froim the uploaded file Stream to my destination Stream. With large files this should be extra beneficial because there is no waiting time for the large file to get uploaded and my gut feeling tells me this way the memory footprint should also be lower. What I need is a forward-only Stream. No seeking needed. Therefore, I don't need to manage the entire uploaded file at some point in time. I just want to send the bytes as soon as they are received (with some lightweight processing in between).
I am developing an ASP.NET application that takes user input and serializes them into a text file. Now, when a second update request comes while the file is still being written, an IOException will be generated.How do I handle concurrent update request to this file?
View 2 RepliesOne of the current projects I'm working on is converting an existing Access front end to a web app for a SQL Database. I wasn't involved in the original design of the, formerly, Access db and front end. I have the project nearly complete except for one remaining task, which involved links to part datasheets for a particular part.
The current db has a table with 8 columns "File1" through "File8". For each datasheet created for the part one of these columns is populated with the UNC path to the file, "<Server><Department>Documents<filename>.pdf". The Documents folder currently has over 16000 files stored there. The Access front end has a series of textboxes with associated file save, file open, and delete buttons for each. I could do the same think in the webform where I need to allow access but it doesn't seem very clean.
I've thought about importing the documents to the SQL db then use a fileupload method to maintain them, which I've used in apps for new databases but that seems like a daunting task with the existing db.
Any way to use the existing file path data in the db and existing document folder to allow access to the documents and the user to manage them?

When I am adding below code on image button click to download file it doesn't work. It says "Internet explorer cannot display webpage".

I'm using a HttpHandler to intercept PDF file download requests and modify the PDF file. I'm stuck on what to do if the requested file doesn't exist on the webserver. If I handle the Exception and return an empty response, it gives the user a 0 byte file to download. If I ignore the Exception, then ASP.NET catches it and the user is redirected to my unfriendly customError page.

View 3 RepliesI 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?
