Downloading Double The Size Of Actual File?
May 23, 2010
I have a website that hosts video files. Some are small around 5mb and some are up to 200mb. This site is not live yet, but when I try to do a test download, it doesnt show the total file size, it just shows how much it has downloaded and the speed.
I tried downloading a 5mb file and once it completed it had actually downloaded 15.2mb. The file worked fine but why was it so large when the actual file is not that size at all. The type of files that are donwloaded are FLV's and MOV's.
I have tested this on IE 6, IE 8, Chrome, Safari, and Firefox, all with the same results.

I've always been required show download size next to the file hyperlink. Only the file in question is rebuilt everyday and the file size can change often. So needless to say the size has been wrong for months. I'm not going to update our site daily to display needless info.
instead of
<a href="file.xxx">click here to download (20mb)</a>
I'd prefer
<a href="file.xxx">click here to download [sizeof('file.xxx')]</a>
The best solution would be javascript based or similar.

I want to embed a silverlight app into a web page and have the height/width of the div that contains the silverlight control match the dimensions of the actual size of the silverlight control.
I essentially want the div to stretch to accommodate the size of the silverlight control. I do not know what size the silverlight control will be before it loads as it is pulling in data and adding controls dynamically. I want to avoid dueling scroll bars and use only the browser scroll bars.
I need this to work in both IE and Firefox.Is there a way to accomplish this?

I have made an application where I am displaying the .pdf , .doc , .docx files. These files are uploading from an Admin Panel.When user place a mouse pointer on download icon provided in front of every file, it shows the complete path where it’s get saved.I want to avoid this path visibility even when user place mouse on download icon and even if it Inspect an element (as most modern browser will have this functionality).

we are working on a file download page. We want to download a file with a name with spaces and accents. Although the filename is shown correctly on the filedownload dialog, when we click open, the file name is shown with %e1%ba%a3n%20... on notepad. ('Save as' shows the correct name) This problem only happens in Internet Explorer.
Is there anyway we can Display the file name correctly (on the target application) after opening it (without saving) from file download dialog ?
We use this code to set the filename :
fileName = Server.UrlPathEncode(fileName);
Response.AppendHeader("Content-Disposition", "attachment; filename="" + fileName + """);

I am working on a http based (NOT Secure) Web Application. In this, I have provided a provision to add some appointment to the Client's outlook calendar. I am creating the .vcs file dynamically when clicked on a hyperlink. The code of generating .VCS file is:
string calendarFormat = GetVCSFormat();
Response.ContentType = "text/calendar";
Response.AppendHeader("content-disposition", "attachment; filename=MyCalendar.vcs");
Response.Write(calendarFormat);
Response.End();
It is working fine in all browsers except IE. It is giving me following error:Internet Explorer cannot download GenerateAppointment.aspx from server. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found.

I'm trying to write come code for users to download files, but the files are located above the webroot (e.g. c:downloads)
I've found some code online that allows me to download a file via a url parameter/argument which is perfect, but the files need to be located within the website structure.
<%@ Page language="vb" runat="server" explicit="true" strict="true" %><script language="vb" runat="server">Sub Page_Load(Sender As Object, E As EventArgs)Dim strRequest As String = Request.QueryString("file") '-- if something was passed to the file querystringIf strRequest <> "" Then 'get absolute path of the fileDim path As String = Server.MapPath(strRequest) 'get file object as FileInfoDim file As System.IO.FileInfo = New System.IO.FileInfo(path) '-- if the file exists on the serverIf file.Exists Then 'set appropriate headersResponse.Clear()Response.AddHeader("Content-Disposition", "attachment; filename=" & file.Name)Response.AddHeader("Content-Length", file.Length.ToString())Response.ContentType = "application/octet-stream"Response.WriteFile(file.FullName)Response.End 'if file does not existElseResponse.Write("This file does not exist.")End If 'nothing in the URL as HTTP GETElseResponse.Write("Please provide a file to download.")End IfEnd Sub</script>
Source: http://www.xefteri.com/articles/show.cfm?id=8
how this can be modified so that it can access files outside the webroot?
I'd like it so that I can create an href like: <a href="download.aspx?file=test.pdf">Download File</a> and then the code will download the file from c:downloads est.pdf

I have VB code that parses XML data from a webpage. Up until 2 days ago the XML data could be viewed right on the page and I could just grab the HTML source code to get the information. Now they have changed the page to a link button to download the XML file.
The problem is that when I click on the XML link I get the 'File Download Prompt' which asks me to run or save the file. I figured I could just save the file to temp directory and then open it up to parse it in my VB app but I can't figure out how to grab the file from the browser in my application.

1. xml parsing error not well-formed --> this error is getting only in mozilla.

I have an export to excel functionality on my web application. WHen the user clicks the "Export to Excel" button, the file is created and it will ask the user to open it or save it to their local machine.
Since the file creation process takes a long time, I added the ajax update progress control. SO now, as soon as the user clicks the "Export to Excel" button, the progress bar image shows up, but after the file is created, I get the following error.
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.
I know that, if we use Response.write in the code behind, we get this error. But I have to use Response.Write because I am presenting the user with a prompt to save or open the newly created file. Is there any other way to do this?
The following is the aspx code.
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdateProgress ID="UpdateProgress1" runat="server">
<ProgressTemplate>

I'm downloading a file from my intranet site and on Chrome, it works as expected. But when I try it on IE, it crashes.
ASP.NET Code:
<a href="../nbd.exe">TEST</a></h2>
Is there something I need to do just for IE?
Also, it works fine in Opera and Firefox. So just IE...

I want to know two things about ASP.NET MVC2 that I've researched from Google but still confusing. Hope I can find clear and clean answer here.
First, how to upload a file to server with custom file path. (Eg. to /Content/Files)
Second, how to download that file, since the url has applied URL Rounting, how to map to them?

In my ASP.Net page, I allow users to download files from the server. If the file is of even a moderate size (does it with a 40 meg file, for example), when downloading, it fails with the error message:
"Insufficient system resources exist to complete the requested service".
I've checked out the server, and it's quiet (CPU, RAM, Hard Drive, Task Manager Processes, etc all very low in their numbers).
I've run the code from several client machines and I'm getting this error message no matter where I run it from.

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?

Ive created a Web App where it is possible to download an xml file from the server to the client. It works just fine except that the Save Dialog recognizes the file being dowloaded as of type .aspx and the name of the file as being the name of the page I' on. The page is called Download.aspx and it contains a button that when clicked executes the following code:
[Code]....
The save dialog appears and says:
Name: Download.aspx
Type: ASP.NET Server Page, 1,16KB
From: 127.0.0.1
If I download the file and open it it contains the correct Xml file content and nothing else, so it is working correctly. It just annoys me that it appears to the user that he is downloading the aspx site (and it shows up as such in windows explorer as well) rather than the xml file which is the actual content.
