Internet Explorer Shows Error When Downloading Excel File In SSL Site?

Mar 8 10 at 3:55

I get the following error when downloading excel file in SSL site:

Internet Explorer cannot download xxxx.aspx from mysite.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.

After googling, I suspect that it's the problem of the response header. I try the solution in this page and set the header:


HttpContext.Current.Response.AddHeader("Pragma", "no-cache");
HttpContext.Current.Response.CacheControl = "private";

Web Forms :: Unable To Execute Code After Downloading File To A Browser

Jul 30, 2010 02:04 AM

I have a web app which displays some data in a GridView. This GridView is populated with a method called BindGrid. The user selectes one or more rows from the grid, then clicks the Process button. What needs to happen is that the selected rows are assembled into a CSV file which is downloaded to the browser, then the database is updated to reflect which rows were selected, and the grid is refreshed so the previously selected rows are no longer displayed. This all sort of works, except...

My code is below, which is very similar to lots of snippets found in this forum.

The problem is that if I uncomment Response.End(), or replace it with ApplicationInstance.CompleteRequest, it all works great except none of the code after Response.End() executes, and so the log entry is not made and the grid is not refreshed.

If I comment Response.End(), as in the snippet below, the code following does run, including the log entry and the call to BindGrid. (I know that because log entries inside BindGrid are made.) However, the page does not refresh. If I press F5 to refresh the page, it redraws correctly refreshed.

So the question is, how do I refresh the page after downloading the file?

I have tried calling both Response.Redirect and Server.Transfer after BindGrid

For what it is worth, I am using IE7.

SQL Server :: Unable To Open The Physical File

Oct 20, 2010 09:11 AM

I'm getting tired figuring out this error. Well, Basically. I have uploaded my ASP.net website to a server (IIS installed) as well as the VB project I made.

BOTH are connecting to a DB named CLIENTS.

the website uses a datagrid to show data, while the VB Project updates the DB based on a monitored folder.

The Problem is If the website is opened first the VB project shows an error "Unable to open the physical file (MDF). Operating system error 32 (error not found)" and Vice Versa if the VB project is first started.

C# - Automatically Open File After Downloading In Silverlight 4?

Dec 9 10 at 2:35

I am creating an excel spreadsheet server side and downloading to the client via a Silverlight front-end. It is started by the user clicking a button and being presented with a SaveFileDialog. Once the user enters a file name then silverlight starts an asynchronous call to a web service and when finished returns a byte array which is written to wherever the user requested to save it. This all works fine.How do I then automatically open this file on the client's PC?

It's probably a simple mistake I'm making but I'm not able to open an asp file on internet explorer. When I try that ie pops up a file transfer window asking me if I want to open or keep the asp file. If I answer "open" it actually opens the file with Dreamweaver where I've orginaly created it.

Internet Explorer - Unable To Download File

Jan 26 at 17:22

In our ASP.NET web site we have developed an aspx page that allows the user to download a file. The file path is sent as a parameter and then the file contents are read and written to the response stream. The code that we have used is the following:

string filepath = HttpContext.Current.Request.Params["FilePath"];
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(filepath));

Everything works as expected in our development environment, but when we use this piece of code in our production server, we noticed that when trying to download almost all kind of files, nothing happens in the browser. It just opens a new window for that aspx page, but then it gets closed almost inmediately. It is very weird since we have tried downloading .pdf, .doc, .xls, .txt and image files with no luck, except with some (not all) .msg files.

We have being looking for a clue sniffing the HTTP traffic that reach to the browser with Fiddler, but we have seen nothing strange. In all cases the file contents are sent to the browser with no differences, so it seems that it is the browser doesn´t show the open/save/cancel dialog. Here is a sample of the headers received in the browser with a failing file:

HTTP/1.1 200 OK Proxy-Connection:
Keep-Alive Connection: Keep-Alive
Content-Length: 421395 Via: 1.1
IBISA01 Date: Wed, 26 Jan 2011
12:02:54 GMT Content-Type:
application/octet-stream Server:
Microsoft-IIS/7.5 Cache-Control:
private Content-Disposition:
attachment;filename=P08-0656 Interflex
Especificación Inteface SGA ERP
Version 0.1.pdf X-AspNet-Version:
4.0.30319 X-Powered-By: ASP.NET

And these are the headers of a file that can be downloaded:

HTTP/1.1 200 OK Proxy-Connection:
Keep-Alive Connection: Keep-Alive
Content-Length: 290816 Via: 1.1
IBISA01 Date: Wed, 26 Jan 2011
12:03:29 GMT Content-Type:
application/octet-stream Server:
Microsoft-IIS/7.5 Cache-Control:
private Content-Disposition:
attachment;filename=Acalaracion final
Fichero ascii proveedores
Interflex.msg X-AspNet-Version:
4.0.30319 X-Powered-By: ASP.NET

In all cases, the full contents of the file appear after the headers with apparently no problems related to encoding. We are wondering if there is some possibility to debug or trace the Internet Explorer activity to see why is rejecting to download the files. The web server has Windows Server 2008 R2 and IIS 7.5. The browsers that we are using are IE 8.0 over Windows 7.

Downloading File To Web Server?

Jun 18, 2009 01:16 PM

First of all, I am looking to "download" a file from a url to a remote web server, not upload a file from a client to the web server.

I have an application that needs to be deployed on multiple domains on my web server. The application is quite large so I want to avoid uploading via FTP for every domain.

Since the control panel software we use (HELM) prevents the copying of files between domains, I would like to host the installation files at a specific url then create an installer that is uploaded to the new domain and downloads the files to disk from the remote location.

I know I can do this using System.Net.WebClient.DownloadFile method e.g:

string url = "http://mysite/installers/installer.zip";
WebClient client = new WebClient();
client.DownloadFile(url, Server.MapPath("~/installer.zip"));

I need to clarify that the file is downloaded from the remote connection by the web server - and NOT downloaded to client and uploaded to the web server (using the clients internet connection).

Since both source and destination servers are on the same network they should transmit the installation file much quicker than if i was to upload it using FTP.

WebClient.DownloadFileAsync Downloading The File On Server

Oct 25 10 at 8:08

I am downloading a file from a remote location to my local machine. The paths I am using are saved in web.config and are in following format:

<add key="FileFolder" value="Files/"/>
<add key="LocalFileFolder" value="D:REAL" />

the code I am using to download is:

WebClient webClient = new WebClient(); [code]...

When i deploy it on the server; and run my program, i get a message saying that download has completed successfully. But the problem is that the file is downloaded on the server machine in the filefolder (LocalFileFolder). I want it to be downloaded on the local machine. What is it that I am doing wrong?

Downloading A File From ServerA And Saving It On Own Server

Nov 03, 2008 05:46 PM

I have a need to download some large files from any server (like a regular download) but save them on my own server.

The need for this is because I hate keeping my machine on over nights, especially when I travel and some sites that I download big files don't allow resuming, my server does, and I have unlimited bandwidth on my Server.

I've used this with PHP before to transfer video's from server to server using their own connections, which blows regular ADSL / Cable out of the water. I'm looking for a solution in ASP.NET

Web Forms :: Open Files Without Downloading

Aug 21, 2009 01:16 PM

I'm attempting to add file collaboration to the intranet system I've developed for my company. Well the thing that caused the system they had bought prior to my starting that failed terribly is with the file manipulation you had to download the file, save it to your hard drive, edit the file, then upload it again... (they are used to having a network drive and abuse it horribly but it's only "a double click" away.

So what I want/need to do for this to survive and replace our horrible "Shared Drive" is a means of making it so when a user goes to open a file on the intranet instead of the whole download, etc, etc ,etc it opens the file directly from the network drive. That way when the user saves it also saves directly back to the network drive. (I realize this will be a project with permissions etc, but I already have a plan on how I can make this work if I get past my current hurdle, where I also don't have to worry about users simply bypassing the system all together)

and also in Javascript with the following code:

Downloading A File From An FTP Server To Local Drive Using StreamWriter?

Nov 07, 2010 05:51 PM

i have been trying to solve this for hours with no luck. i seem to be missing something fundamental.

i have a remote FTP server with a file called log.txt on it, i wish to allow web users to download this file to their local drive to a designated folder.

i have a function calling this sub i found on the web with the filename to download.when trying to run this code i get this error:

" Could not find a part of the path 'C: empFtpDownloadsFolderlog.txt'. "


if i replace this line:


i get no error but the file is not in the TempPath. (it shows it to be saved to "C:WindowsTEMPlog.txt" )

i have a feeling its being save on the server instead of my local drive.

Web Forms :: Downloading Files From Remote Ftp Site?

Sep 28, 2009 09:41 PM

I have already wired up code that checks a remote ftp site for files and downloads the files to a local directory for processing, but the problem I now have is how to most efficiently determine whether the file already exists on the local system first. This project is going to manage files for book conversions, and there will easily be thousands of books, and perhaps tens of thousands of images, pdf files, xml files, etc. That being the case, doing a recursive check on the file system to locate and compare every existing file to the file currently slated for download will be very costly.
