C# - How To Detect That A File Was Successfully Received By A Webclient
Feb 18, 2010
My question is similar to http://stackoverflow.com/questions/194579/how-to-detect-when-a-user-has-successfully-finished-downloading-a-file-in-php but I have to do the same using IIS, ASP.NET and C#.
None of the methods in the HttpResponse class provide feedback if the data was sent or not, TransmitFile just does its job (or not) and does not provide any means of knowing the result.I was thinking of using the .Filter property but then again, the filter is based on the HttpResponseStream which does also not provide any feedback.

we have windows xp operating system, here we installed my website that will be stored in the location(c://programFiles/) if we run the sample after executing ouputfile(scan.pdf)image file will be stored in C://inetpubs/ftproot/(if file transfer type is FTP). if file transfer type is HTTP then the image file is transfered to the location:c://programFiles/website1/app-data. If we install the same website in windows 2007 64 bit os website will be stored at c://programfile x(86)/. if we run the sample through ftp it is running fine and file is stored at FTP folder. but if we run the same application through HTTP, file is not transferring to destination folder(c://programFiles x(86)/website1/app-data.)

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:
CreateDirectoryIfDoesNotExist();
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?

I have an aspx website and I'd like to upload a file to it. The file is being processed later, so I need to support some extra information with it.
This is the website I have to far:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Upload.aspx.cs" Inherits="ABC.Web.Upload" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="Form1" method="post" enctype="multipart/form-data" runat="server">
<input type="file" id="File1" name="File1" runat="server" />
<input type="text" id="FileId" name="FileId" runat="server" />
<input type="submit" id="Submit1" value="Upload" runat="server" />
</form>
</body>
</html>
This (and the code behind) works very well when using a browser and clicking through the form. But I want to upload the file using the WebClient from C# code. I don't have to use the WebClient. I can also modify the upload.aspx to suit me, there is no requirement that it works from a browser, but this is the only example I've got working.
Looking at fiddler (I just started using it, so I probably have missed it) I could not figure out how I would create such a request from code.
At the moment when using the WebClient I am specifying the address and the local filename. I have a breakpoint in the code behind in my website but the File1 and FileId are not set (as expected).
How do I have to modify the website and how do I have to use the WebClient to get the upload working?
EDIT: Just found out about the Request.Files, that will give me the file, but how about the other fields?

I'm trying to use a java servlet in a 3rd party tool's web interface (CA service desk) to invoke it's download file functionality using a webclient in vb.net. The trouble is the text stream from response is markup and not the acutual text file stream.
It's like the page is redirecting to another page which actually presents the file for downloading. I have no idea what the redirected page URL is.
Is there a way I can process this redirected page in order to get at the download using a system.net.webclient?

Referencing my Earlier Question, regarding downloading a file from a server and handling exceptions properly. I am positive that I had this solved, then in classic programming fashion, returned days later to frustratingly find it broken
Updated code:
private static void GoGetIt(HttpContext context)
{
var directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe = new FileInfo(......); [code]....
This was working fine, and returning the zip, otherwise if the file didn't exist returning 404. Then on the client side I could handle this:
public bool Download()
{
try
{
using (var client = new WebClient()) [code]....
But the problem now is two things.
1) I get System.Threading.ThreadAbortException: Thread was being aborted in the server side try-catch block. Usually this was just a file not found exception. I have no idea what or why that new exception is throwing?
2) Now that a different exception is throwing on the server side instead of the file not found, it would seem I can't use this set up for the application, because back on client side, any exception is assumed to be filenotfound.]

In my asp .net project, my main page receives URL as a parameter I need to download internally and then process it. I know that I can use WebClient's DownloadFile method however I want to avoid malicious user from giving a url to a huge file, which will unnecessary traffic from my server. In order to avoid this, I'm looking for a solution to set maximum file size that DownloadFile will download.

I am using webclient object to download a file to a windows folder from a sharepoint document library. The credentials I am passing to the webclient object are that of site collection administrator. everything works fine while i test it by uploading a file to the document library. But since the document library is email enabled; when an email is received the file is not transferred to the windows folder. i have put some workflow history events to see which user account is used when the email is received. the user account shown is the network service account. I have given write permissions on the folder to all the users; Everyone, Network service, the site collection administrator user etc. but still i cant figure out what is the problem.

I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too.
Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive.
The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their respective formats.
For example, lets say that there are 2 files I need to display, one is tiff and one is PDF. The page should show up with a tiff image, and perhaps a link that would open up the PDF in a new tab/window.
The problem:
As these files are all extension-less I had to force IIS to just serve everything up as TIFF. But if I do this, the PDF files won't display. I could change IIS to force the MIME type to be PDF for unknown file extensions but I'd have the reverse problem.

Is this problem easier than I think or is it as nasty as I am expecting?

I'm developing a website that has modular section. I would like it that when a new aspx (and aspx.cs) file is placed in a subdirectory of the application that I can ask the class some information...The idea is that when the file is placed in the directory a new menu item is added to the menu. To do that I need to "ask the class" for its name, icon, description, etc. Is there a way to determine the class that is defined in codebehind file and to instantiate an instance of it?I know I could look for and parse a config file for each plugin but I would rather not have to go that route.

using vb.net/asp.net 2005
I am opening and reading and I need to detect the encoding of the file that I am reading. There are different system users who will be using different encoding in their files so I have no control over this.
[Code]....
While the default encoding normally works there are special foreign language (non-English) characters that are not being read correctly, instead there are garbage characters in their place that I see "myString" above. Good foreign characters are visible in the file but the result in myString are unreadable garbage characters that are not valid.
I have researched this and it has been suggested to determine the encoding of the file and then use that encoding, but I have not been able to find out how to to do this.
so in a nutshell: how can I use vb.net to detect the encoding of an excel file?

I'm trying to let the user download different documents where the data is stored in an SQL DB. In firefox, the filetype is correctly read, but not in IE. I'm trying to do this without having to set the ".pdf" or whatever extension the document has, because I haven't got that information. I only have the filetype.

My users like to upload password-protected Word documents into our custom document management system. I'd like to add a validation to check for the password and refuse the upload if it has a password.
Automating Word - with COM interop - is out of the question because this is a server side application.
