Assume we have the access to sth.avi on [URL] with a direct link.
e.g : [URL] Also we have a website => www.dl2.com.
Now, we wanna let some users to download sth.avi from [URL], but we don't have enough space on [URL] to save sth.avi. Is it possible in ASP.NET for us to read sth.avi from www.dl.com as streaming file and share it without saving the file on our domain.
P.S: I don't wanna share this link [URL], actually I wanna share something like this link [URL]

I changed an app so one of the edit screens opens as a pop-up window via showModalDialog. Previously everything was done in the same window and more back and forth navigation was required. The pop-up provides greater continuity. Unfortunately, as a pop-up, files will not stream to the desktop. If I bring up the page by entering a URL on the address line, so it is not a pop-up, files stream to the desktop OK.
Streaming a file to the desktop is done as follows:
[Code]....
This causes an open/save/cancel dialog to appear in the browser. Does anyone have an idea why a file cannot be streamed to a pop-up window? To get pop-ups to work I always include
[Code]....
in the header. That way I can open other pop-ups such as warnings and database error messages from a prvious pop-up.
I don't think there is a way around this but figured I'd ask... We have an application where a user can generate PDF documents that are streamed to the browser. There is some additional functionality going on behind the scene and I would like to be able to display a message to the user (via updating a literal tag on the page). I don't get any errors when doing this but the page isn't updated and the message isn't displayed. My guess is that streaming the document blocks any other content from going down to the client. In particular, we're using CeTe Dynamic PDF and calling one of their methods but I think it's essentially just doing a Response.BinaryWrite to stream out the PDF.
View 6 RepliesWhen user requests to download a document, I'm writing out a PDF file to HttpResponse using HttpResponse.OutputStream.Write method. It works in every browser except Firefox(3.5.8). In Firefox it sometimes displays the file and sometimes it displays the actual byte stream. When it displays a byte stream, http response is never finished. I see 'transferring data' status and the byte stream ends with EOF. After some time, I get 'connection was reset' window.
Here is response header:

I wrote an ASP.Net web page that will take a QueryString and stream a file to the client. The file is stored in a SQL Server database. Everything works great when I'm running the web site locally during development. When I run it in production from the server I can get a file through Firefox, but not Chrome. In Chrome I get Error 100 (net::ERR_CONNECTION_CLOSED): Unknown error.See some other posts that mention this could be related to Content-Length, however, I can't understand why this would work in development and not production. For that reason I think there must be something else going on here.Here is my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim Data_ID As String = Request.QueryString("Data_ID")
Using dt As New Enterprise_Error_Log.Field_FileDataTable

I have a third party CMS system that can create forms but can't manage true File upload capabities. I am able to get users brows for thier file and have the value submited to my custom .net code behind page for processing. So I end up with like "C:somefilefoldersomefile.doc".
But on my processing page I want to read this file (like the file uploader) and save it to a location. I tried using the file uploader control (but have it not visible) but realized I can't preset it as I was planning to set it and do the normal processing from there. Is there another way to do this?

I have an httpmodule and it has a handler for OnEndRequest. I am trying to write the HttpContext.Response.OutputStream to a file. I am trying to use the Read method of it. But when it is called the exception message i get is "Specified method is not supported". So i am not able to do what i want that is, write the response to a file on the disk. I am able to write the HttpContext.Request.InputStream to a file using its Read method which i do in a handler for OnBeginRequest.

How can I remove the layover after the dialog is done?
Most of my DAL functions use structures to pass the data back to the BLL and to the UI. I have got the try catch code now and it all works fine. I capture the exceptions in a seperate db table and it all works fine.I wanted to know how to pass the error up and what varable would be used to hold the error statusWhat I was think was - if I had a BO structure that was used to in the DAL and was populated and I wanted the error state up do I need to have a specific error field in the structure.
