I am curious as to how the file sharing sites like rapidshare detect users downloading files through download managers.
How do you enable an ASP.NET web application to prevent downloads from a download manager.
I'm trying to create a ZIP file on the fly which might contain a few thousands of pictures.
[code]....
My question:
Is there a way to initiate the download (let the download manager on client side popup), and then start writing on the stream?
I monitored w3wp.exe (IIS) process, and it seems that the data is being written on memory instead of Stream.
When w3wp.exe memory usage riches a certain number, it releases the memory and nothing happens (no download).
I currently have an asp.net page which a loggd in user goes to and theres a bunch of dynamically generated links to zip files that he or she owns and can downloads.Currently they click download and I have no way of knowing if it completes succesfully etc so can't log it. I do log the attempt.Is there are good download manager or solution I can use so they will have progress bars on the site, they can queue multiple ones up and most importantly I can track failed and successful downloads.
View 1 Repliesi want to show info like how much time will be requited to download file in client machine. every client will have different internet speed so how can i detect and show time required to download file in client machine. is it possible in asp.net.
View 2 RepliesIn an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is:
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.AddHeader("Content-Disposition", "attachment;filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.End();
This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this:
HttpResponse response = HttpContext.Current.Response;
response.ClearHeaders();
// Setting cache to NoCache was recommended, but doing so results in a security
// warning in IE6
//response.Cache.SetCacheability(HttpCacheability.NoCache);
response.AppendHeader("Content-Disposition", "attachment; filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.Flush();
response.End();
However, I don't believe that any of the changes made will fix the issue.
I'm trying to use jquery.Ajax to post data to an ASP.NET MVC2 action method that returns a JsonResult. Everything works great except when the response gets back to the browser it is treated as a file download instead of being passed into the success handler. Here's my code:

If I open the downloaded file the json is exactly what I'm looking for and the mime type is shown as application/json. What am I missing to make the jquery.ajax call receive the json returned?
I have a mail list where i can select many mails and download (with/without opening the mail). During the download process i update the mail status(download/open) and show the content in pdf. In normal browser dialog opens where user can save open or cancel options exits. But if the user cancel then the update process done on the mail should not happen. so i think about doing the update process if the user clicks open or save but how can i identity that client control (i think it depend on the browser)
The issue is present if i download and unopened mail and click cancel button in the dialog box the pdf creation code i have done is in this link

which i used to open that dialog in browser to save pdf

I'm downloading a vCard to the browser using Response.Write to output .NET strings with special accented characters. Mime type is text/x-vcard and French characters are appearing wrong in Outlook, for example Montréal;Québec .NET string shows as Montréal Québec in browser.Apparently vCard default format is ASCII. .NET strings are Unicode UTF-16.I'm using this vCard generator code from CodeProject.com
I've played with the System.Encoding sample code at the bottom of this linked MSDN page to convert the unicode string into bytes and then write the ascii bytes but then I get Montr?al Qu?bec (progress but not a win). Also I've tried setting content type to both us-ascii and utf-8 of the response.If I open the downloaded vCard in Windows Notepad and save it as ANSI text (instead of default unicode format) and open in Outlook it's okay. So my assumption is I need to cause download of ANSI charset but am unsure if I'm doing it wrong or have a misunderstanding of where to start.Update: Looking at the raw HTTP, it appears my French characters are being downloaded in the unexpected format so it looks like I need to do some work on the server side...

View 7 RepliesI am using VSTS 2008 + C# + .Net 3.5 + Silverlight 3.0 + ASP.Net to develop a Silverlight application (a video media player) in browser and the function is simple, just use MediaElement to play a remote video file.The remote server is Windows Server 2008 + IIS 7.0 + IIS Media Bit Rate Throttling Control.Since the request media URL can be discovered (e.g. from traffic sniffer), and I want to know how to prevent from download directly from the Url? i.e. I want end user to use my Silverlight media player application in browser to play the file, prevent them from download to local directly. Any easy and quick solution or reference code/documents?

Does anyone know if it is possible to measure when a file has been downloaded?
I place files for clients to download but there are two things I need to know. One is if the file has been downloaded at all at any point. Second is how many times the file has been downloaded. Can each file (usually but not always image files - sometimes pdfs) be tagged in some way to record what happens to it?
I am building an excel file using the OpenXml sdk 2.0. I am putting it in a memory stream and outputting it to the browser.The problem I am receiving is wiht IE 9 if I click Open it says "filename couldn't be downloaded". If I hit save/save as and save it to the filesystem, then open it, the file opens fine with no errors.
In Firefox regardless of if I use save or open the file when opened in excel says its corrupt.I already built the file by writing it to the filesystem first and that code works. Also since saving to desktop in IE lets me open the file, im assuming the problem has to be with the settings on the Response.BinaryWrite.

I am working on a web application and in ASp.Net using VB.net. The requirement is to create a csv file on the server and the user should be able to save the file on his machine. I am creating a csv file on the server and throwing the contents of the csv file to the user using Response.Write method.The problem I am facing is instead the csv file content, user is getting the html code of the page which he is accessing I wrote the following code in my aspx.vb :
strPhysicalPath = Server.MapPath("CSV/" & PathVirtual)
appendFileContents(AppStartupPath, "strPhysicalPath : " & strPhysicalPath)
Dim objFileInfo
As System.IO.FileInfo
objFileInfo = New System.IO.FileInfo(strPhysicalPath)
Response.Clear()
How can I get the csv content in the file that is being downloaded by the user?

View 1 RepliesThe web app in question provides a UI for editing a client (in the business sense, not the browser sense), identified by a ClientID. I store the ClientID in Session, which gets passed from page to page, along with a number of other pieces of data in Session. Works great.
The problem is that if the user opens a new browser window using Ctrl N or File->New Window (in IE), the new window comes up with the same page as the current page, with the same session info. Then if the user navigates to a different client in the 2nd window, the ClientID in session refers to the new client. If they go back to the original browser window and save, the original client gets saved using the 2nd ClientID, and all hell breaks loose, because now the data from the two jobs are intertwined.
I have enabled trace and verified that the new browser window uses the same SessionID as the original. If an entirely new instance of IE is opened, it has a different SessionID, so is not a problem. I have not yet investigated other browsers, such as Chrome or Firefox.
Is there any way to determine if a browser instance is opened for a web app which is already open in another window or tab? Or to prevent that from happening?
In my app, there is a grid that you can drill down. You can go back to prev view via some links but the back bowser button is not integrated to that, so that if you do hit the back browser button, it logs out of the app which I don't want. I would be happy if it would redirect to the first page. I think this part is what we need. [URL] this is the startpage.xaml, at the end there is the hyperlink - so maybe here I can see if the back browser is pressed ( there is no other place in the codes that would navigate out), and if this is pressed I can redirect to a different spot? Is this a sound idea and how do I check if this back browser has been pressed?
