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?
I'm new to this forum, infact this is the first forum i hav ever joined. I need some help urgently as i'm reaching the deadline of my project.I created an asp.net website, where administrator will upload files to SQL database which is connected to the webpage. From the web page there will be a download link to download those uploaded files. I have been successful in uploading files to the database. But nothing is striking in my mind regarding how to download files directly from database using asp.net C#.
View 11 Repliesi made a file uploader to folder named (Books) and i saved the name and the bath of the uploaded file to my DataBase but when i wanna download the uploaded file from the server ? how i make it ? by hyperlink ?
View 3 RepliesI am working on some project where I am needed to allow users to upload files, but only in pdf and .doc format. Now I know how to let users upload files, but I do not know how to check whether an uploading files is pdf and .doc or not. How could I know that? And how could I know the size of each file, for the file should be no greater than 3 MB?
Also, I have alloted a separate folder for the files that are uploaded by users. I have one page that displays the links to download the files in that folder. I needed to know how could I keep the track of the folder, for the files get uploaded every time? Or in other words, how could my 'downloads page' know about the files in that folder and create links for each file in that folder for the download? Also, if I create a link of a file for downloading purposes, will the file be downloaded when one clicks the link?
I am using an ASP.NET FileUpload to upload files to the server. How to upload it to the rootfolder of my project. I want to add the files to a collection or list of files to be shown on the webpage in the form of gridview. Each file should have a link to itself in the list So that it could be downloaded by the click-if desired. The gridview will also have a delete column so that I can delete any of the corresponding file-as desired.
View 3 RepliesI 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).
View 1 Replieswe 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 + """);
My requirement is client has to download files which were uploaded by employees. But if the file name contains a space, Mozilla Firefox use only the name up to the first white space and remaining name is truncated. Is it issue with mozilla firefox? if so how can i get rid of this. Important thing is in IE its working well.
View 2 RepliesI 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 have a link button which the user clicks on it and will download a .PDF file into their PC.It is just a file for them to download.
Currently, I have the following code.
Response.Clear()
Response.Buffer = True
Response.AddHeader("content-disposition", "attachment;filename=Savings Account eStatement.pdf")
Response.Charset = ""
Response.ContentType = "application/vnd.pdf"
Dim objSw As New StreamWriter("Savings Account eStatement.pdf")
objSw.Close()
lblMsg.Text = "Your file created successfully"
lblMsg.ForeColor = Color.Green
'Response.Output.Write(sw.ToString())
Response.Flush()
Response.End()
' Download the file
Response.Redirect("~/Savings Account eStatement.pdf")
Response.Flush()
Response.End()
i am making a gridview in which textfield of password should match with the password stored in the database (table) .As soon as that happens, the file should be ready to download . now the problem is that the code is niether working nor showing any error, which is very sarcastic.
if (txtval.Text != null || txtval.Text !="")
{
if (txtval.Text == ds.Tables[0].Rows[0]["FilePassword"].ToString())
{
lblmessage.Text = "File has been downloaded successfully.";
WebClient fileReader = new WebClient();..........
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>

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.
I am trying to find a way to prevent a PDF from being printed or downloaded when view from web. Also, it is prefered that user cannot Print screen.
According to the required futures, it will cose a lot to create a desktop application from scratch.
I am thinking about converting those PDF files to Flash.
I have 4 checkboxes named(Laptop, Car, Phone, TV) and a button. when user checks one Car checkbox and clicks a button, car specifications pdf should be downloaded. Similarly when phone or laptop checkbox checked, relevant pdf's should be downloaded. For this i have written following code

I wrote download excel file in my code. If I click download button I need show ajax-load image (pnlPopup panel). But it is not displaying. I think because of Some "Response" statements (see below code). Download working fine, but simultaniously I want show loader panel too.
<asp:Panel ID="pnlPopup" runat="server" visible="false">
<div align="center" style="margin-top: 13px;">
<asp:Image runat ="server" ID="imgDownload" src="Images/ajax-loader.gif" alt="" /> <br />
<span class="updateProgressMessage">downloading ...</span>

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:UpdateProgress ID="UpdateProgress1" runat="server">

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...
Here is the code I'm using:

Works great on localhost. But when I upload it to the server with IIS6.it works 25% of the time. the other times, I just get an empty (0 bytes) file to download.
i have designed an c#.net application in which i am uploading the files and saving them into a directory.
now i want to download them.
i had wrote a code to download files,its neither giving any result nor error.
the code is as :

i got following error when downloading ZIP file having size 4GB the error says
The size parameter must be between zero and the maximum Int32 value.
Parameter name: size
Actual value was 2166897372.
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?
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 am currently developing an ASP.net application, where I generate a word document in server and I want to save it in client machine who access that feature with out user interactions. How can I download it and save it in client machine, using javascript?
